Angular validation function implementation steps

This time I will bring you the steps to implement the Angular verification function. What are the precautions for implementing the Angular verification function? The following is a practical case, let's take a look.

The complete example code is as follows:

nbsp;html>

  
    <meta>
    <title>angular验证功能</title>
    <script></script>
    <style>
      input{
        display: block;
      }
      ul li{
        color: red;
      }
    </style>
    <script>
      angular.module("myapp",[])
      .controller("demoC",function($scope){
        $scope.datas = [{
            id: 10011120,
            name: "iphoneX",
            num: 99
          },
          {
            id: 10011121,
            name: "华为mate10",
            num: 20
          },
          {
            id: 10011122,
            name: "vivoR12",
            num: 55
          }
        ]; //定义一个数组
        $scope.save=function(){
          //创建一个存放错误信息数组
          $scope.error_val=[];
          var reg_id=/^\d{8,8}$/; //只能8位数字
          if(!reg_id.test($scope.id)){
            $scope.error_val.push("资产编号格式，必须为数字，且长度为8位");
          }
          //资产名称
          if($scope.name==undefined||$scope.name==""){
            $scope.error_val.push("资产名称不能为空!");
          }else{
            for(var i in $scope.datas){
              if($scope.name==$scope.datas[i].name){
                $scope.error_val.push("资产名称已经存在");
                break; //结束循环,已经查找到资产名称不合法
              }
            }
          }
          //资产数量
          var reg_num=/^\d{1,}$/; //只能8位数字
          if(!reg_num.test($scope.num)){
            $scope.error_val.push("资产编号数量，必须为数字");
          }else{
            if($scope.num<=0){
              $scope.error_val.push("资产编号数量必须大于0");
            }
          }
          //何时添加进行,何时不添加
          if($scope.error_val.length==0){
            $scope.datas.push({
              id:$scope.id,
              name:$scope.name,
              num:$scope.num
            });
          }
        }
      })
    </script>
  
  
    

                                                                                      

资产编号	资产名称	资产数量
{{d.id}}	{{d.name}}	{{d.num}}

    

      

        资产编号         资产名称         资产数量         

          

            
•               {{e}}             
          

                          资产录入
