php下使用kindeditor插件，用js始终获取不到内容，。

<?phpfunction smarty_function_html_kindeditor(){    $editor1='        <script type="text/javascript">        var editor1;		kindeditor.ready(function(k) {			var editor1 = k.create(\'textarea[name="content1"]\', {				csspath : \'/wxy/view/plugins/code/prettify.css\',				uploadjson : \'/wxy/view/upload_json.php\',				filemanagerjson : \'/wxy/view/php/file_manager_json.php\',				allowfilemanager : true			});			prettyprint();		});	</script>		<textarea name="content1" style="width:700px;height:200px;" id="content1"></textarea>	       <input type="button" value="提交" id="subcontents"/> ';    return $editor1;}

//jquery代码		$("#subcontents").click(function(){			 alert("字符串长度："+($("#content1").val()).length+"类型："+(typeof $("#content1").val()));		});
