中文汉化版,官方只有英文的。同时根据中国国情修改了部分验证规则。
这个插件支持大部分的浏览器,但由于有使用到了css3的阴影和圆角样式,所以在IE浏览器下无法看到圆角和阴影效果(万恶的IE)。

普通验证的例子:http://www.position-relative.net/creation/formValidator/
ajax验证的例子:http://www.position-relative.net/creation/formValidator/demoSubmit.html
jquery.validationEngine-en.js是语言文件,所有的提示都在这个文件找的到,可以很方便的转成其他语言,同时你也可以在这个文件内定制属于自己的验证规则。
验证规则是写在表单元素的class属性内。比如下面:
验证规则非常多样,基本上包含了所有的数据类型的验证。
所有的验证规则写在validate[]内,有多种验证,用逗号隔开,这里简要说明下常用的验证规则。
validationEventTriggers属性就是修改绑定事件,上面是增加了个keyup,也就是键盘按键起来就触发验证。
promptPosition就是控制位置,有5种模式:topLeft, topRight, bottomLeft, centerRight, bottomRight
这几个参数很好理解。
这里需要对后台脚本返回的数据进行下说明:
返回的数据格式是json。
出现一个错误,产生一个数组,如下:
二:修改过的地方
解决ie6下select遮挡div的办法
jquery.validationEngine.js要修改的地方:
calculatedPosition.callerTopPosition += "px"; calculatedPosition.callerleftPosition += "px"; calculatedPosition.marginTopSize += "px"; //add matychen if ( $.browser.msie && /6.0/.test(navigator.userAgent) ) { $(divFormError).append('<iframe class="iframe" frameborder="0" scr="javascript:false;"></iframe>'); } // add matychen $(divFormError).css({ "top": calculatedPosition.callerTopPosition, "left": calculatedPosition.callerleftPosition, "marginTop": calculatedPosition.marginTopSize, "opacity": 0 });
validationEngine.jquery.css里面加入以下代码:
.iframe { position: absolute; width: expression(this.parentNode.offsetWidth+\'px\'); height: expression(this.parentNode.offsetHeight-32+\'px\'); z-index: -1; top: expression(((parseInt(this.parentNode.currentStyle.borderTopWidth)||0)*-1)+\'px\'); left: expression(((parseInt(this.parentNode.currentStyle.borderLeftWidth)||0)*-1)+\'px\'); }

jquery.validationEngine-cn.js如下:

部分jquery.validationEngine.js
/* AJAX VALIDATION HAS ITS OWN UPDATE AND BUILD UNLIKE OTHER RULES */ if(!ajaxisError){ $.ajax({ type: "POST", url: postfile, async: true, data: "validateValue="+fieldValue+"&validateId="+fieldId+"&validateError="+customAjaxRule,//+extraData,//自己把其中的+extraData去掉了,不然后面的ajax验证有问题。 beforeSend: function(){ // BUILD A LOADING PROMPT IF LOAD TEXT EXIST if($.validationEngine.settings.allrules[customAjaxRule].alertTextLoad){ if(!$("div."+fieldId+"formError")[0]){ return $.validationEngine.buildPrompt(ajaxCaller,$.validationEngine.settings.allrules[customAjaxRule].alertTextLoad,"load"); }else{ $.validationEngine.updatePromptText(ajaxCaller,$.validationEngine.settings.allrules[customAjaxRule].alertTextLoad,"load"); } } },
struts.xml文件:
<struts> <package name="json" extends="json-default"> <!--验证--> <action name="validate" class="com.bw30.zjvote.action.ValidateAction" method="vali"> <result type="json"> <param name="excludeProperties">msg</param>//jsonplugin-0.32.jar </result> </action> </package> </struts>
validateAction
public String vali() { ActionContext ac = ActionContext.getContext(); HttpServletRequest request = (HttpServletRequest) ac .get(ServletActionContext.HTTP_REQUEST); String validateId = request.getParameter("validateId"); logger.info("vali() - String validateId=" + validateId); String validateValue = request.getParameter("validateValue"); String validateError = request.getParameter("validateError"); logger.info("vali() - String validateError=" + validateError); //注意下面的顺序,感觉这是个缺陷之一,不过可以在jquery.validationEngine.js更改, jsonValidateReturn.add(validateId); jsonValidateReturn.add(validateError); if(validateValue.equals("chen")) jsonValidateReturn.add("true"); else jsonValidateReturn.add("false"); return SUCCESS; }
jquery.validationEngine.js要更改的地方:
success: function(data){ // GET SUCCESS DATA RETURN JSON data = eval( "("+data+")"); // GET JSON DATA FROM PHP AND PARSE IT ajaxisError = data.jsonValidateReturn[2];//这里官方文档写死了,可以根据自己需求更改。 customAjaxRule = data.jsonValidateReturn[1];//这里官方文档写死了,可以根据自己需求更改。 ajaxCaller = $("#"+data.jsonValidateReturn[0])[0]; fieldId = ajaxCaller; ajaxErrorLength = $.validationEngine.ajaxValidArray.length; existInarray = false; if(ajaxisError == "false"){ // DATA FALSE UPDATE PROMPT WITH ERROR; _checkInArray(false) // Check if ajax validation alreay used on this field if(!existInarray){ // Add ajax error to stop submit $.validationEngine.ajaxValidArray[ajaxErrorLength] = new Array(2); $.validationEngine.ajaxValidArray[ajaxErrorLength][0] = fieldId; $.validationEngine.ajaxValidArray[ajaxErrorLength][1] = false; existInarray = false; }
用到了jsonplugin-0.32.jar这个包在附件里面,其他struts的包,自己添加。
需要注意的地方:
1.每一个需要验证的控件必须给定ID。
2.验证框架的版本尽可能同JQuery的版本保持一致, 比如新版本的最好用JQuery 1.7的, 否则会有bug
或者直接不能运行, 所以如果根据上述步骤配好的还不能运行的话, 可用用Firefox 的Firebug 打开控制台
调试一下, 也可以尝试更换JQuery的版本。
有问题可以一同研究。
