jquery的表單驗證問題

如果發現自己的表單驗證不起作用，但是寫了

注意找那些最易忽略的地方例如小小的逗號

$.validator.setDefaults({submitHandler: function() {waitSubmit();mainForm.submit();}});$().ready(function() {if(window.screen.availHeight <= "600"){$(".apply_main").attr("style","align:left;width:700px;height:350px;overflow:auto;");init('450px','300px');$("#sCont2").attr("style","height:300px");}if("${applyCailDetAsso.applyTitle}" == ""){    addRow('productTable', 'setTr');    }stringValidator();fmtTableBackground(document.getElementById("commonTable"));$("#mainForm").validate({rules: {"applyCailDetAsso.applyCailDet.parameterCh": {required: true,byteRangeLength: [0,200]},"applyCailDetAsso.applyCailDet.parameterEn": {required: true,byteRangeLength: [0,200]},"applyCailDetAsso.codeString": {required: true},"applyCailDetAsso.applyCailDet.begintime": {required: true},"applyCailDetAsso.applyCailDet.count": {required: true},     //次地方的逗號},messages: {"applyCailDetAsso.applyCailDet.parameterCh": {required: "【主要校準參量】內容未填寫！",byteRangeLength: $.format('【主要校準參量】填寫內容超長！最大應為{1}個字元（一個中文算3個字元）。')},"applyCailDetAsso.applyCailDet.parameterEn": {required: "【Parameter】內容未填寫！",byteRangeLength: $.format('【Parameter】填寫內容超長！最大應為{1}個字元。')},                //例如這個地方的逗號最容易被忽略}});});
