主要用到了以下几个文件
1 js文件 jquery.validationEngine.js | jquery.validationEngine-cn.js | jquery.js
2 css文件 validationEngine.jquery.css
3 在需要验证的页面引入以上文件

注意 上面有部分粗体标示的地方 是用来验证用户名是否重复的(这里折腾了好久才出来)
在 jquery.validationEngine-cn.js中有这样一段
- "ajaxUser" :{
- "file" : "[i]syncTask!val.action[/i]" ,
- "alertTextOk" : "* 帐号可以使用." ,
- "alertTextLoad" : "* 检查中, 请稍后..." ,
- "alertText" : "* 帐号不能使用." },
上面斜体部分是你的action 或servlet 都可以
下面是比较重要的你后台返回的东西了
- public void val(){
- this .getResponse().setContentType( "text/html;charset=utf-8" );
- try {
- PrintWriter out=this .getResponse().getWriter();
- ActionContext ac = ActionContext.getContext();
- HttpServletRequest request = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);
- String validateId = request.getParameter("validateId" ); //获取插件post参数validateId
- String validateValue = request.getParameter("validateValue" ); //获取插件post参数validateValue
- String validateError = request.getParameter("validateError" ); //获取插件post参数validateError
- boolean flags = this .iFacadeSyncTask.valdateTaskName(validateValue);
- String message = "" ;
- if (flags){
- [b]out.println("{'jsonValidateReturn':['" +validateId+ "','" +validateError+ "','false']}" );[/b]
- }else {
- [b]out.println("{'jsonValidateReturn':['" +validateId+ "','" +validateError+ "','true']}" );[/b]
- }
- }catch (Exception e){
- e.printStackTrace();
- }
- }
上面加粗的地方就是前台页面需要的东东
