Select all and invert z during checkout in AngularJS shopping cart

This time I bring to you, what are the precautions, the following is a practical case, let's take a look.

Without further ado, I will just post the code for you. The specific code is as follows;

nbsp;html>


 <meta>
 <title></title>
 <link>
 <style>
 .p1{
  margin: 20px;
 }
 </style>


<p>
 </p><h4 id="angularJS-购物车实现全选-取消全选">angularJS--购物车实现全选/取消全选</h4>
 <button>添加商品</button>
 <button>删除商品</button>
 <br><br>
 

                                       

操作	check状态	商品名称	单价	数量	小计
	{{p.checked}}||{{p.checked}}	{{p.name}}	单价：￥{{p.price}}	数量：	小计：￥{{p.sum}}

 
 全选取消全选  

 已选择{{jishuqi}}件商品，总金额：￥{{ sumTotal }} <script></script> <script> angular.module(&#39;testMo&#39;,[&#39;ng&#39;]).controller(&#39;testCtrl&#39;,function($scope){ // $scope.p1=new Object(); // $scope.p1.price=10; // $scope.p1.count=1; //购物车应该是一个数组 $scope.selectAll=false;//全选默认为false $scope.cart=[{id:0,name:&#39;商品0&#39;,price:10,count:5,sum:10,checked:false}]; $scope.addProduct= function (){ var p=new Object(); p.id=$scope.cart.length; p.name=&#39;商品&#39;+ p.id p.price=Math.floor(Math.random()*100);//对数值向下取整 p.count=1; p.sum= p.price* p.count; p.checked=false; $scope.cart.push({id: p.id,name: p.name,price:p.price,count: p.count,sum: p.sum,checked: p.checked}); console.log($scope.cart); } //删除商品 $scope.deleteProduct= function (){ $scope.cart.pop();//删除数组中的最后的一个元素，并且返回这个元素，会改变数组里的元素 } //全选按钮check的点击事件 $scope.selectAllClick= function (sa) { for(var i=0;i<$scope.cart.length;i++){ $scope.cart[i].checked=sa; } } //单个数据的check事件 $scope.echoChange=function(id,ch,se){ $scope.cart[id].checked=!ch; //当所有都选中时，全选也要被勾选 var cc=0;//计算当前数组中checked为真的数目 for(var i=0;i<$scope.cart.length;i++){ // if($scope.cart[i].checked==true){ // cc++; // } $scope.cart[i].checked?cc++:cc; } $scope.selectAll=(cc==$scope.cart.length);//当为真的数目=数组长度时，证明全部勾选 // console.log($scope.selectAll); } //监控数据 $scope.$watch(&#39;cart&#39;,function(newValue,oldValue,scope){ $scope.sumTotal=0; //总计 $scope.jishuqi=0; //计数器 for(var i in newValue) { var sumN = newValue[i].count * newValue[i].price; //计算出新的结果 $scope.cart[i].sum = sumN.toFixed(2); //保留两位小数并且把它赋值给元数据; if (newValue[i].checked) { $scope.sumTotal += sumN; $scope.jishuqi++; // console.log($scope.sumTotal); // console.log($scope.jishuqi); } } },true); /*$watch简介:在digest执行时，如果watch观察的的value与上一次执行时不一样时，就会被触发。 AngularJS内部的watch实现了页面随model的及时更新。 $watch方法在用的时候主要是手动的监听一个对象，但对象发生变化时触发某个事件。 $watch(watchFn,watchAction,deepWatch); 如果不加第三个参数，那么只会监听cart数组，只有当cart引用改变时才会触发,因此当需要监听一些引用对象时需要把第三个参数设置成true。 */ }); </script>

PS: Let me share with you the code of the angularjs shopping cart. The specific code is as follows:

  <meta>
  <title>购物车</title>
  <script></script>


<center>
<h2 id="商品列表">商品列表</h2>
<p>
  <!--导航栏-->

          <input>   
           产品价格:
          <select>

            <option>1000-2000</option>
            <option>2000-5000</option>
          </select>

<script>
  angular.module(&#39;product&#39;,[])
    .factory(&#39;productList&#39;,function(){
      return [
        { id:910,name:"imac",price:15400 },
        { id:80,name:"iphone",price:5400 },
        { id:29,name:"ipad",price:14200 },
        { id:500,name:"ipad air",price:23400 },
        { id:1200,name:"ipad mini",price:22000},
        { id:100,name:"android",price:9990 }
      ]
    })
    .controller(&#39;productController&#39;,function($scope,productList){
      /*$scope.search = "ipad";//定义一个变量
      alert($scope.search);*/
      $scope.productList=productList
      $scope.orderColumn=&#39;name&#39;; //排序字段
      $scope.orderSign=&#39;-&#39;;   //为空时正序 为负号时倒序
      $scope.sortProduct=function(sortColumn){ //点击列标题排序事件
        $scope.orderColumn=sortColumn;//觉得按照那一列进行排序
        if($scope.orderSign=="-"){
          $scope.orderSign="";
        }else{
          $scope.orderSign=&#39;-&#39;;
        }
      };
      //删除产品
      $scope.delProduct = function(name){
        //alert(name);
        if(name!=""){
          if(confirm("是否删除"+name+"商品") ){
            var p;
            for (index in $scope.productList) {
              p = $scope.productList[index];
              if(p.name == name){
                $scope.productList.splice(index,1);
              }
            }
          }
        }
      }
      //清空购物车
$scope.removeAll = function(){
if(confirm("你确定要清空购物车所有商品吗?")){
$scope.productList = [];
}
}
    });
</script>
</center>

Okay, this ends the code.
