角JS不允许preventDefault或返回false在表单提交工作

问题描述

我有一个表格，我想通过AJAX提供：

I have a form I'd like to deliver via AJAX :

<form class="form-inline ng-pristine" ng-submit="sendForm()" method="post" action="/sign_up" accept-charset="UTF-8">

$scope.sendForm = (e) ->
  e.preventDefault ->
  console.log 'sendForm()'
  return false  

将出现的console.log ，并立即将其传递的形式。

The console.log appears, and immediately it delivers the form.

它忽略了两个即preventDefault（）和返回false 。

AngularJS提醒蜜獾的我。它只是不小心。

AngularJS reminds me of the honey badger. It just doesn't care.

推荐答案

好了，你不这样做的角路。角提供了一个名为NG提交指令，这是否preventDefault你（只要你没有你的表格上指定的操作属性）

Well, you're not doing it the "Angular way". Angular provides a directive called ng-submit, which does that preventDefault for you (as long as you don't have an action attribute specified on your form).

标记（与验证！）

<form name="myForm" ng-submit="sendForm()">
  <div>
    <input type="text" name="name" ng-model="data.name" required/>
    <span ng-show="myForm.name.$error.required && myForm.name.$dirty">required</span>
  </div>
  <div>
    <input type="email" name="email" ng-model="data.email" required/>
    <span ng-show="myForm.name.$error.required && myForm.name.$dirty">required</span>
    <span ng-show="myForm.name.$error.email && myForm.name.$dirty">invalid email</span>
  </div>
  <button type="submit" ng-disabled="myForm.$invalid">Submit</button>
</form>

code

app.controller("MyCtrl", function($scope, $http) {
    $scope.sendForm = function (){
       $http.post('/Submit/To/Url', $scope.data).success(function(data) {
           alert('done!');
       });
    };
});
