Angularjs中使用指令綁定點(diǎn)擊事件的方法

本篇文章主要介紹了Angularjs中使用指令綁定點(diǎn)擊事件的方法，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下。

項(xiàng)目中，模板中的菜單是jQuery控制的，在Angularjs中就運(yùn)行不到了，因?yàn)椴藛雾?xiàng)是ng-repeat之后的。

如html

<ul id="main-menu">
 <li class="">
  <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Menu1</a>
  <ul class="sub-menu">
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
  </ul>
 </li>
  <li class="">
  <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >Menu2</a>
  <ul class="sub-menu">
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
  </ul>
 </li>
</ul>

Jquery給第一級(jí)a鏈接綁定事件代碼像:

$(function(){
 $("#main-menu li a").click(function(e){
   if ($(this).next().hasClass('sub-menu') === false) {
        return;
     }
     console.log("click");
 });
});

因?yàn)槲抑翱催^(guò)文檔說(shuō)，Angularjs的Controller不處理Dom的操作，所以一直在找方法怎么處理和jQuery 一樣綁定a的點(diǎn)擊事件,在看了jQuery not working with ng-repeat results之后，原來(lái)可以將所有鏈接的單擊事件，放在一個(gè)指令中。如果在Controller中綁定了ng-click,并操作了Dom元素，就不太規(guī)范了，使用指令會(huì)好一些。

html

<ul id="main-menu">
 <li class="">
  <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" toggle-main-menu>Menu1</a>
  <ul class="sub-menu">
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
  </ul>
 </li>
  <li class="">
  <a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" toggle-main-menu>Menu2</a>
  <ul class="sub-menu">
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--1</a></li>
    <li ><a href="javascript:;" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >--2</a></li>
  </ul>
 </li>
</ul>

javascript:

.directive("toggleMainMenu", function() {
  return {
    restrict: "A",
    link: function(scope, elem, attrs) {
      $(elem).click(function() {
        if($(this).next().hasClass('sub-menu') === false) {
          return;
        }
      console.log("click");
      });
    }
  }
});

原來(lái)指令是這樣使用的。以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
