Question

js 获取 含有<div class="tt"></div>

<div class="nb">1</div>
<div class="dd">2</div>
<div class="tt">3</div>
<div class="tt">4</div>

Answer 1

如果没有ID,没有NAME,只有class的话，要方便快捷的获取标记内容，建议你使用jquery。
先去下载个jquery包，然后导入到页面。http://feiyu.asgard.cn/article_50.html

然后语句就可以简单很多啦！

$('.tt')

就这么简单！

Answer 2

<script type="text/javascript">
window.onload = inifDiv;
function inifDiv(){
var divFF = document.getElementsByTagName("div");
for(var i=0; i<divFF.length; i++){
if(divFF[i].className == "tt"){
var divValue = divFF[i].innerHTML;
alert(divValue);
}
}
}
</script>

上面的JS是寻找所有class = "tt"的div;然后弹出该div标签里所包含的内容;

Answer 3

getElementsByClass('tt');

function getElementsByClass( searchClass, domNode, tagName)
{
if (domNode == null) domNode = document;
if (tagName == null) tagName = '*';
var el = new Array();
var tags = domNode.getElementsByTagName(tagName);
var tcl = " "+searchClass+" ";
for(i=0,j=0; i<tags.length; i++)
{
var test = " " + tags[i].className + " ";
if (test.indexOf(tcl) != -1)el[j++] = tags[i];
}
return el;
}

用innerHTML可以获取HTML标记
