Solution to the problem that the iframe of document.createElement in IE cannot set the attribute name_javascript skills

The name of the iframe can be the target of a link or form. Open the link or form to this iframe.
I encountered an issue before where I couldn’t set the name attribute of an iframe in IE

JavaScript code

var iframe = document.createElement('iframe');  
iframe.name = 'ifr';  
//iframe.setAttribute('name', 'ifr'); //这样也不行 

Neither of the above two methods can be set. Later I found out that it can also be created like this

JavaScript code

var iframe = document.createElement('');

This is no problem in IE, but this method cannot be passed in Firefox. So finally

JavaScript code

　try{  
   var iframe = document.createElement('<iframe name="ifr"></iframe>');  
  }catch(e){ 
    var iframe = document.createElement('iframe');  
    iframe.name = 'ifr';  
 }

This way it is compatible.
