一个基于jQuery的数据验证插件，比较好用
其中自定义验证需要在：jquery.validationEngine-zh-CN.js jquery.validationEngine-zh-EN.js中分别实现
例如添加一个验证：在一个class为js_needSum 的层中的input 输入的数字之和为100
(function($){ // 验证规则 $.fn.validationEngineLanguage = function(){}; $.validationEngineLanguage = { newLang:function(){ $.validationEngineLanguage.allRules = { "requiredInFunction": { "func": function(field,rules,i,options){ //alert("11"+field.attr('type')); var objs = field.parents(".js_needonlyone").find("input"); var bFg = false; for(var j=0; j< objs.length; j++){ if(objs.eq(j).is(":checked")){ bFg = true; break; } } return (bFg) ? true : false; }, "alertText": "* '升级选项'和'降级选项'必须选择一个" }, "SumEqual100": { "func": function (field, rules, i, options) { //alert("11"+field.attr('type')); var objs = field.parents(".js_needSum").find("input"); var bFg = false; var sum = 0; for (var j = 0; j < objs.length; j++) { //alert(objs.eq(j).val()?"":"0"); sum += parseFloat(objs.eq(j).val() == "" ? "0" : objs.eq(j).val()); } if (sum == 100) { bFg = true; } return (bFg) ? true : false; }, "alertText": "和必须为100" }, "SumEqual1": { "func": function (field, rules, i, options) { //alert("11"+field.attr('type')); var objs = field.parents(".js_needSum").find("input"); var bFg = false; var sum = 0; for (var j = 0; j < objs.length; j++) { sum += parseFloat(objs.eq(j).val() == "" ? "0" : objs.eq(j).val()); } if (sum == 1) { bFg = true; } return (bFg) ? true : false; }, "alertText": "和必须为1" }, "required":{ // Add your regex rules here, you can take telephone as an example

调用html：
<li> <div class="js_needSum"> <p><label>A<input type="text" class="text fwd40 validate[custom[numberAndInteger]]" /></label></p> <p><label>B<input type="text" class="text fwd40 validate[custom[numberAndInteger]]" /></label></p> <p><label>C<input type="text" class="text fwd40 validate[required,custom[numberAndInteger],custom[SumEqual100]]" /></label></p> </div> </li>
表单提交时需要引用验证引擎：
jQuery('.js_form').validationEngine({
showOneMessage: true,
ajaxFormValidation: true,
ajaxFormValidationMethod: 'post',
//onBeforeAjaxFormValidation: showLoading,
onAjaxFormComplete: ajaxValidationCallback
});
好的程序员，他们删掉的代码，比留下来的还要多很多。
