Element.getElementByTag（“ mytag”）有时返回空

Question

CKeditor Element1's outer html as below:

<element1 id="s1">
<mytag>Test1</mytag>
<span> </span>
Some text
<mytag>Test</mytag>
<span> </span>
<mytag>Test3</mytag>
some text
<span> </span>
</element>

var element1=EditorIns.document.getById("s1");
EditorIns.focus();
var mt=element1.getElementsByTag("mytag");
alert(mt.count());

Normally it's working fine, but sometimes mt.count() is 0.

I also tried with jQuery like this:

$(element1.$).find("mytag").length;

It also has the same problem. Please help me out from this issue

Answer 1

Write the code in a function And call this function same as following :-

<script type="text/javascript">
function testElement(){
var element1=EditorIns.document.getById("s1");
EditorIns.focus();
var mt=element1.getElementsByTag("mytag");
alert(mt.count());
}


window.onload=testElement;

</script>

The element is loading after complete the page load and window.onload will call when all the elements completely loaded on the page.

Answer 2

or

$(element1).find("mytag").length;

if element1 is a regular html element
