我怎么可以触发使用angularjs在NG-点击另一个元素的单击事件？ [英] how can i trigger the click event of another element in ng-click using angularjs?

问题描述

我试图触发＆LT的Click事件;输入类型=文件＆GT; 从按钮元素。

<input id="upload"
    type="file"
    ng-file-select="onFileSelect($files)"
    style="display: none;">

<button type="button"
    ng-click="angular.element('#upload').trigger('click');">Upload</button>

其通常的做法是隐藏已知的变丑兽＆LT;输入类型=文件方式＆gt; ，并通过其他方法触发其click事件

Its common practice to hide the uglified beast known as <input type=file> and trigger its click event by some other means.

推荐答案

如果你的输入和按键是兄弟（他们都是你的情况OP）：

If your input and button are siblings (and they are in your case OP):

<input id="upload"
    type="file"
    ng-file-select="onFileSelect($files)"
    style="display: none;">

<button type="button" uploadfile>Upload</button>

使用指令，你点击按钮绑定到像这样的文件输入：

Use a directive to bind the click of your button to the file input like so:

app.directive('uploadfile', function () {
    return {
      restrict: 'A',
      link: function(scope, element) {

        element.bind('click', function(e) {
            angular.element(e.target).siblings('#upload').trigger('click');
        });
      }
    };
});
