一、jQuery中Ajax的调用(需要引用jQuery代码库)。
方法1:
$.get(url, function(data) { //deal with the data });
方法2:
jQuery.post( url, [ data ], [ success(data, textStatus, jqXHR) ], [ dataType ] ) $.post(url,postdata, function(data) { //deal with the data });
方法3:
$.ajax({ type: "POST",// or get contentType: "application/json; charset=utf-8", url: url, data: "{'countryModel':" + JSON.stringify(countryModel) + "}", dataType: "json",//html,xml,script async: true, //true 表示异步,默认就是true success: function(data) { //deal with the data }, error: function() { // deal with error } });
二、jQuery.Form plugin Ajax(需要引用jQuery代码库和jQuery.Form插件)
基于Form表单的Ajax调用
1.ajaxForm, 这个方法在调用时不是马上提交,只是说明调用的Form要以ajax方式提交,该方法一般在$(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="https://3water.com/Scripts/jquery-1.4.1.min.js"></script> <script type="text/javascript" language="javascript" src="https://3water.com/Scripts/jquery.validate.min.js"></script> <script type="text/javascript" language="javascript" src="https://3water.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"); }
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持三水点靠木。
