单击表单中的按钮会导致页面刷新 [英] Clicking a button within a form causes page refresh

问题描述

我在Angular中有一个表单，里面有两个按钮标签。一个按钮在 ng-click 上提交表单。另一个按钮纯粹用于使用 ng-click 进行导航。但是，当单击第二个按钮时，AngularJS会导致页面刷新，触发404.我在函数中删除了一个断点，它正在触发我的函数。如果我执行以下任何操作，它将停止：

I have a form in Angular that has two buttons tags in it. One button submits the form on ng-click. The other button is purely for navigation using ng-click. However, when this second button is clicked, AngularJS is causing a page refresh which triggers a 404. I’ve dropped a breakpoint in the function and it is triggering my function. If I do any of the following, it stops:

1. 如果我删除 ng-click ，该按钮不会导致页面刷新。


2. 如果我注释掉函数中的代码，它不会导致页面刷新。


3. 如果我使用 href =将按钮标记更改为锚标记（< a> ） ，然后它不会导致刷新。

1. If I remove the ng-click, the button doesn’t cause a page refresh.
2. If I comment out the code in the function, it doesn’t cause a page refresh.
3. If I change the button tag to an anchor tag (<a>) with href="", then it doesn’t cause a refresh.

后者似乎是最简单的解决方法，但是为什么AngularJS甚至在我的函数之后运行任何代码导致页面重新加载？好像是一个错误。

The latter seems like the simplest workaround, but why is AngularJS even running any code after my function that causes the page to reload? Seems like a bug.

以下是表格：

<form class="form-horizontal" name="myProfile" ng-switch-when="profile">
  <fieldset>
    <div class="control-group">
      <label class="control-label" for="passwordButton">Password</label>
      <div class="controls">
        <button id="passwordButton" class="secondaryButton" ng-click="showChangePassword()">Change</button>
      </div>
    </div>

    <div class="buttonBar">
      <button id="saveProfileButton" class="primaryButton" ng-click="saveUser()">Save</button>
    </div>
  </fieldset>
</form>

以下是控制器方法：

$scope.showChangePassword = function() {
  $scope.selectedLink = "changePassword";
};

推荐答案

如果你看一下 W3C规范，看起来很明显的尝试是用<$标记你的按钮元素c $ c> type ='button'当你不想让他们提交时。

If you have a look at the W3C specification, it would seem like the obvious thing to try is to mark your button elements with type='button' when you don't want them to submit.

特别需要注意的是它在哪里说

The thing to note in particular is where it says

没有指定type属性的按钮元素表示与type属性设置为submit的按钮元素相同的东西

A button element with no type attribute specified represents the same thing as a button element with its type attribute set to "submit"
