Javascript 如何使用“获取HTML”;window.getSelection();

Javascript 如何使用“获取HTML”;window.getSelection();,javascript,internet-explorer,google-chrome,w3c,Javascript,Internet Explorer,Google Chrome,W3c,我的代码: <p id="p"> 123<span>abc</span>456 </p> <script> document.getElementById("p").onmouseup=function(){ if (window.getSelection) { //code } else if (document.selection) {

我的代码:

<p id="p">
    123<span>abc</span>456
</p>
<script>
    document.getElementById("p").onmouseup=function(){
         if (window.getSelection) {
             //code
         }
         else if (document.selection) {   
             alert(document.selection.createRange().htmlText)  //IE6 7 8
         }
    }
</script>

123abc456

document.getElementById(“p”).onmouseup=function(){ if(window.getSelection){ //代码 } else if(document.selection){ 警报(document.selection.createRange().htmlText)//IE6 7 8 } }
在“//code”中写些什么,我可以在chrome或FF中获得相同的htmlText?


这是一个精确的复制品。请关闭.alert(this.outerHTML);而不是警报(selObj);
document.getElementsByTagName('p')[0].onmouseup = function() {
    if (typeof window.getSelection === 'function') {
        //code
        var selObj = window.getSelection(); 
        alert(selObj);
        var selRange = selObj.getRangeAt(0);             
    } else if (document.selection) {   
        alert(document.selection.createRange().htmlText)  //IE6 7 8
    }
}
