js的数组对象怎么阻止代码继续往下执行

Question

let tableDataAdd = [];

this.tableDataAdd.push({
    materialName: '',
    materialNum: '',
    specification: '',
    brandName: '',
    categoryName: '',
    unit: '',
  }, {
    materialName: '',
    materialNum: '',
    specification: '',
    brandName: '',
    categoryName: '',
    unit: '',
  }, {
    materialName: '',
    materialNum: '',
    specification: '',
    brandName: '',
    categoryName: '',
    unit: '',
  }, {
    materialName: '',
    materialNum: '',
    specification: '',
    brandName: '',
    categoryName: '',
    unit: '',
  }, {
    materialName: '',
    materialNum: '',
    specification: '',
    brandName: '',
    categoryName: '',
    unit: '',
  })

我想在保存列表的接口之前做一个验证,只要tableDataAdd里面的materialNum为0或者''阻断代码继续往下执行，不让调取接口该怎么处理，我用了map，some的 return false和break都不行

如下图，本来打算用async-validator表单验证 但是提示在表格里面太丑了

是这个意思吧

const len = this.tableDataAdd.filter(item=>item.materialNum===0).length;
if(len>0) {
    return;
}
request()……
