项目中，模板中的菜单是jQuery控制的，在Angularjs中就运行不到了，因为菜单项是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给第一级a链接绑定事件代码像:
$(function(){
$("#main-menu li a").click(function(e){
if ($(this).next().hasClass('sub-menu') === false) {
return;
}
console.log("click");
}
);
}
);
因为我之前看过文档说，Angularjs的Controller不处理Dom的操作，所以一直在找方法怎么处理和jQuery 一样绑定a的点击事件,在看了jQuery not working with ng-repeat results之后，原来可以将所有链接的单击事件，放在一个指令中。如果在Controller中绑定了ng-click,并操作了Dom元素，就不太规范了，使用指令会好一些。
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");
}
);
}
}
}
);
原来指令是这样使用的。以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。
