項目中，模板中的菜單是jQuery控制的，在Angularjs中就運行不到了，因為菜單項是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"); });});因為我之前看過文檔說，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的點擊事件,在看了jQuery not working with ng-repeat results之后，原來可以將所有鏈接的單擊事件，放在一個指令中。如果在Controller中綁定了ng-click,并操作了Dom元素，就不太規范了，使用指令會好一些。
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"); }); } }});原來指令是這樣使用的。以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
