formValidator向struts2 ajax传參验证

话不多说，直接上代码

页面head里面的formvalidator验证配置

  <script type="text/javascript">
	$(document).ready(function() {
		$.formValidator.initConfig({
			formID : "form1",
			theme : "ArrowSolidBox",
			wideWord : false,
			submitOnce : true,
			onError : function(msg, obj, errorlist) {
				$("#errorlist").empty();
				$.map(errorlist, function(msg) {
					$("#errorlist").append("<li>" + msg + "</li>")
				});
				alert(msg);
			},
			ajaxPrompt : '有数据正在异步验证，请稍等...'
		});

		$("#name").formValidator({
			tipID : "nameTip",
			onShow : "请输入角色名",
			onCorrect : "正确"
		}).inputValidator({
			max : 10,
			onError : "最多输入10个字符。"
		}).regexValidator({
			regExp : "notempty",
			dataType : "enum",
			onError : "请输入角色名"
		}).ajaxValidator({
		   url:"sysRoleAction_isRoleNameAjax.action",
		   type:"post",
		   dataType:"html",
		   data:{roleName:function(){return $("#name").val()},filterName:"${name}"},
		   success:function(data){
			if(data=="true"){
				return false;
			}else{
				return true;
			}
		   },
		   buttons: $("#button"),
		   error: function(){alert("server没有返回数据。可能server忙。请重试");},
		   onError : "该角色名已经存在!",
		   onWait : "正在对角色名进行合法性校验。请稍候…"
		});
		$("#description").formValidator({tipID : "descriptionTip",empty:true,onShow:"请输入你的描写叙述",onCorrect:"恭喜你,你输对了"}).inputValidator({max:20,onError:"最多输入20个字符"});
	});
</script>

struts2 action中script验证的方法

public void isRoleNameAjax() throws IOException {
		/** 文本输出流打印 */
		PrintWriter out = response.getWriter();
		String roleName = request.getParameter("roleName");
		String filterName = request.getParameter("filterName");
		boolean findByRoleName = systemRoleService.findByRoleName(roleName,filterName);
		out.print(findByRoleName);
		out.flush();
		out.close();
	}
