JS实现pasteHTML兼容IE、Firefox和Chrome的方法

核心代码实现

<html>
<body>
<script language="JavaScript">
function test() {
 if (document.selection && document.selection.createRange) {
   var myRange = document.selection.createRange();
   var m = myRange.pasteHTML('<iframe width=100 height=100 src="http://localhost/t2.htm"></iframe>');
 }
 else if (window.getSelection) {
   var selection = window.getSelection();
   var range = window.getSelection().getRangeAt(0);
   range.deleteContents();
   var newP = document.createElement('iframe');
   newP.src="http://localhost/t2.htm";
   newP.width="100";
   newP.height="100";
   range.insertNode(newP);
 }
}
</script>
<p>Highlight a part of this text, then click button below</p>
<input id="myB" type="button" value="Click me" onclick="test();">
</body>
</html>
