插入

后重置所有字段

尝试以下方法：

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.emplist = [{
    empname: 'samudrala',
    empsalary: '4.5 - pam',
    empid: 'Emp - 450'
  }, {
    empname: 'soujanya',
    empsalary: '4.5 - pam',
    empid: 'Emp - 451'
  }, {
    empname: 'suguna',
    empsalary: '4.5 - pam',
    empid: 'Emp - 452'
  }, {
    empname: 'sangeetha',
    empsalary: '4.5 - pam',
    empid: 'Emp - 453'
  }, {
    empname: 'sadhanandham',
    empsalary: '4.5 - pam',
    empid: 'Emp - 454'
  }, {
    empname: 'jai',
    empsalary: '4.5 - pam',
    empid: 'Emp - 455'
  }, {
    empname: 'vijay',
    empsalary: '4.5 - pam',
    empid: 'Emp - 456'
  }, {
    empname: 'Ajay',
    empsalary: '4.5 - pam',
    empid: 'Emp - 457'
  }, {
    empname: 'Sandya',
    empsalary: '4.5 - pam',
    empid: 'Emp - 458'
  }, {
    empname: 'Raamu',
    empsalary: '4.5 - pam',
    empid: 'Emp - 459'
  }];
  $scope.addItem = function() {
    if (typeof($scope.empname) == "string" && typeof($scope.empsalary) == "string" && typeof($scope.empid) == "string") {
      $scope.emplist.push({
        'empname': $scope.empname,
        'empsalary': $scope.empsalary,
        'empid': $scope.empid
      });
      $scope.empname = $scope.empsalary = $scope.empid = null; //reset fields				
    }
  }
});

Answer 2

您需要做的两件事：

添加
使用ng-form验证空对象

Answer 3

首先清除所有字段，然后输入值，它将添加到数组中。

像这样使用：

   $scope.empname="";
   $scope.empsalary="";
   $scope.empid="";
   $scope.emplist = [
                  {empname:'samudrala',empsalary:'4.5 - pam',empid:'Emp - 450'},
                  {empname:'soujanya',empsalary:'4.5 - pam',empid:'Emp - 451'},
                  {empname:'suguna',empsalary:'4.5 - pam',empid:'Emp - 452'},
                  {empname:'sangeetha',empsalary:'4.5 - pam',empid:'Emp - 453'},
                  {empname:'sadhanandham',empsalary:'4.5 - pam',empid:'Emp - 454'},
                  {empname:'jai',empsalary:'4.5 - pam',empid:'Emp - 455'},
                  {empname:'vijay',empsalary:'4.5 - pam',empid:'Emp - 456'},
                  {empname:'Ajay',empsalary:'4.5 - pam',empid:'Emp - 457'},
                  {empname:'Sandya',empsalary:'4.5 - pam',empid:'Emp - 458'},
                  {empname:'Raamu',empsalary:'4.5 - pam',empid:'Emp - 459'}
                  ];
      $scope.addItem = function(){

            if($scope.empname!='' && $scope.empsalary!=''&& $scope.empid!=''){
                console.log('add'); $scope.emplist.push({'empname':$scope.empname,'empsalary':$scope.empsalary,'empid':$scope.empid


                                                        });

重复行添加到我的Emp表和空行也
