經過試驗后發現HTML錨點在JSP中并不兼容。兩者表示錨點的方法有所不同
HTML錨點
<a href="#1">goto1</a>
.
.
.
.
<a name="1">111</a>
這樣從goto1可以定位到111
JSP錨點
<a href="javascript:void(0)" onclick="document.getElementById('1').scrollIntoView();">goto1</a>
。
。
。
<a id="1">1111</a>

通過js事件獲取元素中的屬性值
<div id="c-title1" onclick="openAndClose(this)" value="content1" >報告概覽</div>
function openAndClose(myelement) {
alert(myelement.attributes["value"].value );
}
