项目中有一个小功能 要实现 text字符框中显示斜体的效果 所以参考了xheditor, 网上搜索等
<script src="jquery/jquery-1.4.2.min.js"></script>
<script>
$(document).ready(function(){
// var win = $('#ifr').contentWindow;
var win = document.getElementById('ifr').contentWindow.document;
var html = "<html><body></body></html>"
var s = $('#text_i').val();
//针对IE and !IE 的情况
win.designMode = "on";
win.contentEditable = true;
//
win.open();
//win.write(html);
win.write(s);
win.close();
//alert(win);
});
</script>
<span>
<input type="text" id="text_i" value="<i>斜体</i>" style="display:none;"/>
<iframe id="ifr" width="60" height="20" src="javascript:;">
</iframe>
</span>
