记录一个表单验证功能

$(document).ready(function() {

$.validator.addMethod("regex", function(value, element, regexpr) {          
        return regexpr.test(value);
      }, "Please enter a valid code.");

		$("#inputForm").validate({
			rules:{
				componentCode:{
					required:true,
					rangelength:[6-30],
					regex:/[a-zA-Z0-9]{6,30}/,
					/* regex: /^(?![0-9]+$)(?![a-zA-Z]+$)[0-9A-Za-z]{6,20}$/  */
				}
			},
			messages:{
				componentCode:{
					required:'子件号码不能为空',
					rangelength:'请输入{6}-{30}位字母或者数字',
					regex : '密码必须是数字和字母组合'
				}
			},
			
			submitHandler: function(form){
				loading('正在提交，请稍等...');
				form.submit();
			},
			errorContainer: "#messageBox",
			errorPlacement: function(error, element) {
				$("#messageBox").text("输入有误，请先更正。");
				if (element.is(":checkbox")||element.is(":radio")||element.parent().is(".input-append")){
					error.appendTo(element.parent().parent());
				} else {
					error.insertAfter(element);
				}
			}
		});
