JavaScript in the IFRAME open the file and detect the presence of IFRAME _javascript tips

But Iframe[name], it involves the onload question ... So it's a lot of trouble ....
The following is only added delay ... There is no "real" deal with the onload problem .... In fact, can be recycled window.open to solve, but lazy to get a little ... ^^
<a href= "javascript:void (0);" onclick= "Openc (' http://www.jb51.net/', ' CS ', this)" >jb51.net</a>
<script type= "Text/javascript" >
Window.openc = function (href, target, e) {
try {
window.open (' Javascript:if (!document.body) {Opener.openc.isnull=true;opener.open ("c.asp"); Close ();} ', Target | | '');
Window.settimeout (function () {
if (window.openC.isNull) {
Delete Window.openC.isNull;
Window.settimeout (function () {
E.fireevent (' onclick ');
}, 500);
} else {
window.open (href, target);
}
}, 100);
} catch (exp) {
alert (exp.message);
}
};
</script>
