Get the text after span element using jquery

<div id="mydiv">
    <div>
        <span>Text inside span</span>
        Text next to span
    </div>
    <div>
        Contents inside the 2nd div element...
    </div>
</div>

如果想取得上面html代码中的”Text next to span”，使用下面的方法即可：

var a = $('#mydiv div').first().contents().filter(function(){
    returnthis.nodeType ==3;
}).text();
