请教_如何用脚本将硬回车转换成软回车?

Question

就是把 <p> 转换成 <br>如:<p>abckdfgjoewrgj</p>fhgdrdtshnjdfh    转换成:abckdfgjoewrgj<br>fhgdrdtshnjdfh

Answer 1

<script>
str="<p>abckdfgjoewrgj</p>fhgdrdtshnjdfh";
str=str.replace(/<p>(.*?)<\/p>/g,"$1<br>")
alert(str);
</script>

Answer 2

是因为designMode来的问题么？
<iframe id=demo></iframe>
<script>
demo.document.designMode="on"
demo.document.onkeydown=function (){
if(demo.window.event.keyCode==13){
demo.document.selection.createRange().pasteHTML("<br>")
demo.document.selection.createRange().select();
demo.window.event.returnValue=false;
}
}
</script>
