A iframe with name "frameAccountInfo",it has a input element which name property and id property are "accountStat"
I write a script to get the value of accountSta
<script
1 var acobj = document.frames.frameAccountInfo.document
2 alert(acobj.all)
3 alert(acobj.body.all.accountStat.value);
</script
It alerts [object] and [useable
but if I comment the line 2, it shows a javascript error “missing object", why ?Thanks a lot

Regard

Hi

alert(document.frames["IFRAMENAME"].document.forms[0].ELEMENTNAME.value);
You may want to check the readystate of the frame before accessing it

if(document.frames["IFRAMENAME"].document.readyState == "complete")
