Ajax在Web应用中的作用越来越大，许多工具都包含了对这一功能的使用，以下是对这些常用工具中Ajax的典型实例.
一、jQuery中Ajax的调用（需要引用jQuery代码库）。
1.$.get(url, function(data) { //deal with the data });
2.jQuery.post( url, [ data ], [ success(data, textStatus, jqXHR) ], [ dataType ] )
$.post(url,postdata, function(data) {
//deal with the data }); 3.$.ajax({ type: "POST",// or get contentType: "application/json; charset=utf-8", url: url, data: "{'countryModel':" + JSON.stringify(countryModel) + "}", dataType: "json",//html,xml,script async: true, //true 表示异步，默认就是true success: function(data) { //deal with the data }, error: function() { // deal with error } }); 二、jQuery.Form plugin Ajax（需要引用jQuery代码库和jQuery.Form插件） 中文API地址：http://www.aqee.net/docs/jquery.form.plugin/jquery.form.plugin.html#getting-started 基于Form表单的Ajax调用 1.ajaxForm, 这个方法在调用时不是马上提交，只是说明调用的Form要以ajax方式提交，该方法一般在$(document).ready方法里设置。 2. ajaxSubmit，这个方法在调用时就会马上提交。 var options = { target: '#divToUpdate', url: 'comment.php', success: function() { alert('Thanks for your comment!'); } }; $('#myForm').ajaxForm(options)；或$('#myForm').ajaxSubmit(options)；三、Ajax在MVC中的使用以上两种方法都可以用，另外我们可以MicrosoftAjax，这就必须引用MicrosoftAjax.js, MicorsoftMvcAjax.js这两个文件1.Ajax.BeginForm <% using (Ajax.BeginForm( " action " , " controll " , new AjaxOptions { UpdateTargetId = " ajaxdiv " , HttpMethod = " POST " }, new { id = " AjaxForm " })) { %> < input type = " text " id = " EmployeeId2 " /> < input type = " submit " value = " Submit " /> <% } %> < div id = " ajaxdiv " > </ div > 2.Ajax.ActionLink <%= Ajax.ActionLink( " LinkName " , " action " , " controll " , new AjaxOptions { LoadingElementId = " loadingdiv " , UpdateTargetId = " ajaxdiv " , HttpMethod = " POST " }); %> <div id="ajaxdiv"> </div> <div id="loadingdiv"> </div> 四、jquery.form与jquery.validate结合使用 前端代码 < script type ="text/javascript" language ="javascript" src ="http://www.cnblogs.com/Scripts/jquery-1.4.1.min.js" ></ script > < script type ="text/javascript" language ="javascript" src ="http://www.cnblogs.com/Scripts/jquery.validate.min.js" ></ script > < script type ="text/javascript" language ="javascript" src ="http://www.cnblogs.com/Scripts/jquery.form.js" ></ script > < h2 > AjaxFrom </ h2 > < div id ="output1" style ="color: Red;" > </ div > <% using (Html.BeginForm( " Login " , " Home " , FormMethod.Post, new { id = " loginForm " })) { %> < table border ="0" cellpadding ="0" cellspacing ="0" > < tr > < td > <% = Html.TextBox( " UserEmail " , "" , new { @class = " name required " }) %> </ td > </ tr > < tr > < td > <% = Html.Password( " Password " , "" , new { @class = " required " }) %> </ td > </ tr > < tr > < td > < input type ="submit" value ="submit" /> </ td > </ tr > </ table > <% } %> < script language ="javascript" type ="text/javascript" > $(document).ready( function () { var opts = { submitHandler: function (form) { var submitOpts = { target: ' #output1 ' , success: function () { alert( ' Thanks for your comment! ' ); } }; $(form).ajaxSubmit(submitOpts); } }; jQuery( " #loginForm " ).validate(opts); }); </ script > 后端Action public PartialViewResult Login( string UserEmail, string Password) { // you code return PartialView( " Success " ); }转载于:https://www.cnblogs.com/wangjq/archive/2011/03/08/1977301.html
