大家好我想知道如下的
元素<div id="datatable">
<form id="theForm" name="theForm" >......</form>
<div class="no_data_dd" id="no_data" >....
<div class= ....>.....
<div class= ....>
</div>
</div>
</div>
<div class="score_row score_header">.../div>
<div class="score_row match_line e_true" >..</div>
<div class="score_row padded_date ">..</div>
<div class= ....>.....</div>
</div>
我试过
Set itemEle = objIE.document.getElementById("scoretable")
Length = itemEle.getElementsByTagName("class").Length
length = 0且nont = 5
为什么?
