easyui实现ValidateBox自定义验证数据库中是否存在重复字段

1.jsp页面代码

<script type="text/javascript">
	var isRepetition = false;
	$.extend($.fn.validatebox.defaults.rules, {
		myminLength : {
			validator : function(value, param) {
				var b = $('#pg').propertygrid('getData');
				//alert('hehe' + b.rows[0].value);

				$.ajax({
					tyep : "post",
					dataType : "text",
					async : false,//是否异步执行
					url : "testSystemAndJobRepetition.htm",
				    data:{systemName:b.rows[0].value,jobName:value},
					success : function(result) {
						isRepetition = (result === "true" ? true : false);
					},
					error : function(result) {
						isRepetition = false;
					}
				});
				//alert(isRepetition)
				return isRepetition;
			},
			message : 'Please enter at least {0} characters.'
		}
	});
</script>

2.java代码

	@RequestMapping("/testSystemAndJobRepetition")
	public void testSystemAndJobRepetition(HttpServletRequest request,HttpServletResponse response) {
		String systemName = request.getParameter("systemName");
		String jobName = request.getParameter("jobName");
		logger.info("systemName:" + systemName + ",jobName:" + jobName);
		try {
			response.getWriter().write("" + !etlJobService.isRepetition(systemName, jobName));
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
