我只需要使用jQuery 选择器选择前一个元素.

<li class="collapsable">
    <div class="hitarea collapsable-hitarea"></div>
    <span id="devicelist" class="ankr">Device List</span>
    <ul id="ultree">
        <li type="dev" device="/dev/sdh1" id="dev0" class="litab">
            <img height="20px" width="20px" src="../Images/drive.png" class="dicon">
            <a class="ankr dn" href="#">'/dev/sdh1'</a>
        </li>
    </ul>
</li>

$(document).on("click","#devicelist,**Here Selector will be used**",this,function(event){
    console.log(this);
    console.log(event.target);
});

我想选择有课程的div .hitarea.我正在寻找类似的东西$("#devicelist:div.hitarea")

它应该只使用jQuery 的选择器来完成.

我想在元素上启用/禁用单击事件.我有以下代码......

HTML:

<a id="CP" style="cursor: pointer; text-decoration: underline;">Current Processes</a>

jQuery的:

$(document).on("click", "#CP", function(event) {
    $this = $(this);
    $this.click(function() {
        return false;
    });
    $this.html("Processing...").css({
        "text-decoration": "none",
        "cursor": "default"
    });
    $.ajax({
        type: 'post',
        url: 'abc.jsp',
        success: function(process) {
            //My code goes here...
            $this.on("click"); //  Here i want to bind or add handler which is fired previously.
        }
    });
});
