在textarea文本域中显示HTML代码的方法
这是一个iframe 的
给你一个参考的：
代码如下:
<iframe ID="tryit" MARGINHEIGHT="1" MARGINWIDTH="1" width="100%" height="300" scrolling="auto"></iframe>
<script language=javascript>
tryit.document.designMode="On";
tryit.document.open();
tryit.document.innerHTML+=tryit.document.write("<b>asdf</b>");
tryit.document.close();
tryit.focus();
</script>
这个是textarea
代码如下:
<body>
<textarea id="txt" rows=10 cols=10></textarea>
<button onclick="insert()">click</button>
<script>
function insert(){
var oDiv=document.createElement("DIV");
oDiv.innerHTML="<br><Font color = Red>red<BR></FONT><Font color = Blue>blue</font>";
document.getElementById("txt").appendChild(oDiv);
}
</script>
