开源软件名称（OpenSource Name）：watusi/jquery-mobile-iscrollview开源软件地址(OpenSource Url)：https://github.com/watusi/jquery-mobile-iscrollview开源编程语言(OpenSource Language)：JavaScript 70.6%开源软件介绍(OpenSource Introduction)：watusi/jquery-mobile-iscrollview, Version 1.3.6JQuery Mobile widget plug-in for easy use of the iScroll scroller in JQuery Mobile projects. iScroll is a javascript that can scroll content in a window within a web browser with very similar behaviour to native scrolling on mobile devices such as iPhone and Android. This means you can scroll a window within the browser using native-like scrollbars and physics. jquery.mobile.iscrollview adapts the iScroll javascript to the jQuery Mobile environment. It is an implementation of a JQuery Widget Factory widget. It follows the widget-factory-mobile Widget Factory Pattern. Release NotesPlease see releaseNotes.txt for information on changes in this and prior releases. iScroll Version 4.2.5This widget is not yet compatible with iScroll version 4.2.1 through 4.2.5. Please stick with iScroll 4.2 for now. Some investigation and testing is needed due to changes in iScroll event code. Also, iScroll 4.2.1 introduced and change that may not be desirable. Scrolling continues when your finger leaves the wrapper. While this is a nice feature for small scrollers, this is not always desirable. It is very odd on desktop browsers, as scroll continues when you drag with the mouse, even outside of the browser! It should be optional. (It will be in iScroll5). Roadmap1.4 - Fully implement usejQueryEvents ? - Option to un-enhance widget temporarily (and optionally hide headers/footers) during virtual-keyboard input on select devices (iOS first), to eliminate all form input problems when using a virtual keyboard. ? iOS keyboard handing for inputs. Guess keyboard height based on device/orientation/fullscreen. Resize wrapper to fit page in space above keyboard, center focused element. ? - Better support for collapsible content (scroll on expand if expanded content below window) Plug for jquery.mobile.simultaneous-transitionsThis plugin works best when used with jquery.mobile.simultaneous-transitions It puts back the old, simultaneous, non-scrolling transitions that everybody knew and loved from jQuery Mobile 1.0. It's an ideal companion for jquery.mobile.iscrollview! Stop fighting the goofy transitions in jQuery Mobile 1.1. If you're using iScroll, you probably don't need them. What This is ForThis widget is intended for use in any jQuery Mobile project, but it was designed to be especially useful for some specific uses. First and foremost are native mobile applications that use HTML/CSS/Javascript in a webview for their user interface. It is especially desirable that such applications reproduce a "native" look and feel. A native look and feel is impossible to achieve without an embeddable scroller with native-like physics and scrollbar action. While iScroll4 is useful to help achieve this goal, it is difficult to use along with jQuery Mobile. It is not an easy task to integrate iScroll4 with jQuery Mobile - at least not correctly and efficiently. My intention is that this widget will handle 80% of use cases with very minimal effort. The most common need for iScroll in jQuery Mobile projects is to have a fixed header and footer with a single vertically-scrollable area in-between. This can be accomplished by simply including the required files in the If you need to do something different than this, this widget will probably work for you, but you will probably have to set some options and dig into the documentation a bit. Because the primary target for this widget is native mobile applications, it has a large number of configurable options, which may be usable only in certain target environments. I want you to be able to tailor the widget to your specific needs when you are using it in specific, known environments. Secondarily, it is intended to support websites that will be viewed on mobile browsers, and "full-screen" websites and "web apps" for mobile devices (i.e. "Add to Home Screen" in Mobile Safari). Finally, it supports desktop browsers, and is regularly tested using current versions of FireFox, Safari, Chrome, and Opera. It generally works well in these browsers, and fortunately hasn't needed a lot of work to acheive compatability. This widget is not well-tested on Android devices, and I very much appreciate assistance in ferreting-out Android issues. It is tested regularly in all three modes (Mobile Safari, full-screen, and UIWebView) on iPad 1(5.1), iPad 3(5.1), iPhone 4 (4.3.5) and iPhone 4S(5.1). UsageThe most basic usage of this widget is simple: just add a Note that As well, you may have no content in the wrapper initially. You might do this, for example, if
you will be inserting dynamic content later. In this case, the plugin will create an empty

within the viewport after fixed headers/footers are taken into account. This behaviour can be
disabled using the The widget has been designed to support multiple scrollers on a page - for example, you might want a second, gallery-like horizontal scroller. So, all data related to a scroller is stored in the scroller's container, not the page. Feel free to experiment with multiple scrollers - I just haven't had the need so haven't put the effort into testing and supporting that scenario.

</html>Fixed and persistent Toolbars (Headers/Footers)This plugin now works fairly well with both fixed and persistent toolbars, as long as you use jQuery Mobile 1.1.1 or later. Make sure you use Note, however: do not use If you add You can also use persistent toolbars. The JQM documentation has in the past been ambiguous as to whether these can be used with toolbars other than Navbars. They can: at least with jQuery Mobile 1.1.1. The demo now uses fixed, persistent toolbars for both header and footer. To use a persistent toolbar, assign the same Because the page height is restricted to the viewport height (at least by default) when using this plugin, jQuery Mobile (1.1.1) will not fade the toolbar during transitions. Bear in mind, though, that the combination of fixed toolbars and a page size that equals the viewport height (the default when using this plugin) may cause unwanted results in some enviroments. In particular, in Mobile Safari, this will cause the browser's navigation bar to show during page transitions. So, fixed toolbars are most appropriate only in a native environment (such as when using a WebView with PhoneGap.) I am seeking feedback on how well fixed and persistent toolbars work (or don't) in different
browsers and environments. So, I have enabled fixed/persistent toolbars in the demo. If this causes
issues in your environment, please try with In the demo, you can use see the difference between how jQuery Mobile 1.0.1 and 1.1.1 handle this. You can see that the header is fixed with 1.1.1 but slides with the page with 1.0.1. JQM tries to keep the footer fixed in 1.0.1 but is not completely successful. You will see that sometimes it stays fixed and sometimes it slides with the page transition. Ths seems related to queued transitions. Additionally, you may notice that the footer is shown briefly in the wrong position during transitions. If this is a problem in your environment, you can use an inline footer, and the plugin will insure it always appears in the right place. However, you cannot implement a persistent toolbar in JQM 1.1 with an inline footer. Dynamic ContentIf you will be adding dynamic content that you want to have scrolled, you first need to understand the HTML structure that the plugin creates for you. If you supply initial content, the plugin will create two The outermost If you supplied pull-down and/or pull-up blocks, they are moved to inside the scroller, after the scroller is created. An additional When you add dynamic content, make sure to add it inside the What you wrote: <div data-role="content" data-iscroll>
<p>This is some content that I want to scroll</p>
<p>This is some more content</p>
</div>What the plugin produces: <div data-role="content" data-iscroll class="iscroll-wrapper">
<div class="iscroll-scroller">
<!-- If you included a pull-down under the wrapper, it will wind-up here -->
<div class="iscroll-content">
<!-- If you included no content above under the content div, then this div is empty -->
<p>This is some content that I want to scroll</p>
<p>This is some more content</p>
</div>
<!-- If you included a pull-up under the wrapper, it will wind-up here -->
</div>
</div>RefreshingAny time you alter the content of a scroller, in such a way that the dimensions of the scrolled
content might be changed, you need to refresh the scroller widget using the The Please see the section on the Alternately, you can trigger an Padding IssuesPrevious versions of this widget had some issues involving the way jQuery Mobile standard CSS applies padding and margin to content divs and listviews. The widget now handles this for you in the most common use cases. By default, the widget removes any padding from your wrapper. It then adds a The padding needs to be moved to inside the scroller (and to not include pull-down/pull-up) so that you will not see padding around the scroller itself. There are two options that allow you to override this default behavior: Pull-to-RefreshThis widget supports "pull-to-refresh" functionality. You can have a block of HTML that is positioned above the top or below the bottom of the scroller that the user can pull down or pull up. These blocks can be revealed by scrolling, but the scroller will "snap back" after the user stops scrolling to again hide the block. If the user pulls past this block by a certain amount, (1/2 the height of the pull block) and then releases, some action that you specify will be performed. That action can be anything, but typically will be to perform some AJAX action to retrieve data from a server and refresh or add some content within the scroller. In order to implement pull-to-refresh, you need to add a small amount of HTML markup to your page and either supply a function as an option value or else (recommended) bind or delegate to a jQuery event callback function. You also need to include the file Pull BlockTo implement pull-up and/or pull-down, structure your HTML similar to the following: <div data-role="content" data-iscroll>
<div class="iscroll-pulldown">
<span class="iscroll-pull-icon"></span>
<span class="iscroll-pull-label"></span>
</div>
<ul data-role="listview">
<li>Item 1</li>
<li>Item 2</li>
</ul>
<div class="iscroll-pullup">
<span class="iscroll-pull-icon"></span>
<span class="iscroll-pull-label"></span>
</div>
</div>This is all you have to do to implement the pull-up and/or pull-down UI. The widget doesn't create the pull blocks for you, in order to provide you with the flexibility to format them as you please. The pull blocks can contain other elements, and the spans for the icon and/or label can be omitted. All of the class names used for pull-down and pull-up are configurable in options. The example above uses the default class names. Pull StatesA pull block can be in one of three states:
If the user scrolls back (without lifing) while in the If the user pulls past the edge of the pull block (by 1/2 the height of the pull block), then the block will enter the Loading state. After the action has been performed, and the scroller is refreshed, then the block returns
to the Pull Label TextThe widget has default text values that are inserted into the pull label element when the block enters each state. Each of these text values is a configurable widget option. The applicable options, and their default values are:
To change these options programatically, see the options documentation. Alternately, you can change the default values in your HTML. When you change the defaults in HTML, it changes the corresponding option value. To change the To change the To change the Example: <span data-iscroll-pulled-text="Now let er go, and we'll get some refresh action!"
data-iscroll-loading-text="Ye-haw! Waiting for the data to come through the pipes!"
class="iscroll-pull-label">Pull this here thing down to refresh!</span>Fancier Pull StatesIf you want to do something more elaborate when a pull block enters each state, you can either provide a callback option or (recommended) bind or delegate to a jQuery event callback function. The associated events are:
Event and Callback Option FunctionsIn order to implement the pull-down and/or pull-up action, you need to supply a function. You can either supply this function as an option value or (recommended) bind or delegate to a jQuery event callback function. The example code below is from the demo: $(document).delegate("div.pull-demo-page", "pageinit", function(event) {
$(".iscroll-wrapper", this).bind( {
"iscroll_onpulldown" : onPullDown,
"iscroll_onpullup" : onPullUp
});
});CallbacksYour callback function receives two parameters: eThis is the event object that originally gave rise to the callback. This is probably not very useful to you. dThis is map containing one member, Your callback should take whatever action you want when the user activates the pull-up/pull-down. This might typically involve retrieving some data from a server and inserting it into the scroller content. See the demo for an example. Calling functionsThe standard way of calling widget functions is by passing a sub-function name as a string parameter to the widget function. Any parameters to the function should follow. Note: This method works for all versions of jQuery Mobile from 1.0 to 1.4.x. See below, though, for differences when using an alternative way of calling fucntions. For example, to call the $(".example-wrapper").iscrollview("refresh");The widget factory allows you to access widget functions directly, by accessing a data variable stored in the widget's element. For jQuery Mobile versions < 1.3: $(".example-wrapper").jqmData("iscrollview").refresh();The Widget Factory changed in jQuery Mobile version 1.3. Starting with this version, you can access this variable like this: $(".example-wrapper").data("mobileIscrollview").refresh();While this is a bit awkward, it is also more conventional. It is handy in case you need to make a series of calls to different widget functions. You can first get the instance into a variable. // JQM < 1.3
var myView = $(".example-wrapper").jqmData("iscrollview");
myView.refresh(); // JQM >= 1.3
var myView = $(".example-wrapper").data("mobileIscrollview");
myView.refresh();This means, as well, you can easily call any underlying iScroll function
through the exposed // JQM < 1.3
$(".example-wrapper").jqmData("iscrollview").iscroll.scrollTo(0,10,200,true); // JQM >= 1.3
$(".example-wrapper").data("mobileIscrollview").iscroll.scrollTo(0,10,200,true);So, if you replace iscroll.js with a newer version that has new functions, or if you need to call iScroll private functions, or access iScroll member variables, you can call them without any need to modify this widget. This widget wraps all current iScroll public functions, so the above example can also be called like this: $(".example-wrapper").iscrollview("scrollTo", 0, 10, 200, true);The exceptions are the
