In ie, the IFRAME of document. createelement cannot be set.

The IFRAME name can be the target of the link or form, and the link or form can be opened to the IFRAME.
I have encountered a problem in IE that I cannot set the IFRAME name attribute.

JavascriptCode

VaR IFRAME = Document. createelement ('iframe ');
IFRAME. Name = 'ifr ';
// IFRAME. setattribute ('name', 'ifr'); // No.

Neither of the above methods can be set. Later, we found that we could also create it like this.

JavaScript code

VaR IFRAME = Document. createelement ('<IFRAME name = "IFR"> </iframe> ');
In this way, there is no problem in IE, but this method cannot be passed in Firefox. So last

JavaScript code

Try {
VaR IFRAME = Document. createelement ('<IFRAME name = "IFR"> </iframe> ');
} Catch (e ){
VaR IFRAME = Document. createelement ('iframe ');
IFRAME. Name = 'ifr ';
}

In this way, it is compatible.
