jQuery ajax应用总结
Wang Juqiang 人气:0一、jQuery中Ajax的调用（需要引用jQuery代码库）。
方法1：
复制代码 代码如下:
$.get(url, function(data) {
/https://img.qb5200.com/download-x/deal with the data
});
/https://img.qb5200.com/download-x/deal with the data
});
方法2：
复制代码 代码如下:
jQuery.post( url, [ data ], [ success(data, textStatus, jqXHR) ], [ dataType ] )
$.post(url,postdata, function(data) {
/https://img.qb5200.com/download-x/deal with the data
});
$.post(url,postdata, function(data) {
/https://img.qb5200.com/download-x/deal with the data
});
方法3：
复制代码 代码如下:
$.ajax({
type: "POST",// or get
contentType: "application/json; charset=utf-8",
url: url,
data: "{'countryModel':" + JSON.stringify(countryModel) + "}",
dataType: "json",//html,xml,script
async: true, //true 表示异步，默认就是true
success: function(data) {
/https://img.qb5200.com/download-x/deal with the data
},
error: function() {
// deal with error
}
});
type: "POST",// or get
contentType: "application/json; charset=utf-8",
url: url,
data: "{'countryModel':" + JSON.stringify(countryModel) + "}",
dataType: "json",//html,xml,script
async: true, //true 表示异步，默认就是true
success: function(data) {
/https://img.qb5200.com/download-x/deal with the data
},
error: function() {
// deal with error
}
});
二、jQuery.Form plugin Ajax（需要引用jQuery代码库和jQuery.Form插件）
基于Form表单的Ajax调用
1.ajaxForm, 这个方法在调用时不是马上提交，只是说明调用的Form要以ajax方式提交，该方法一般在$(document).ready方法里设置。
2.ajaxSubmit，这个方法在调用时就会马上提交。
复制代码 代码如下:
var options = {
target: '#divToUpdate',
url: 'comment.php',
success: function() {
alert('Thanks for your comment!');
}
};
$('#myForm').ajaxForm(options)；
或$('#myForm').ajaxSubmit(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
复制代码 代码如下:
<%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>
{
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="//www.qb5200.com/Scripts/jquery-1.4.1.min.js"></script>
<script type="text/javascript" language="javascript" src="//www.qb5200.com/Scripts/jquery.validate.min.js"></script>
<script type="text/javascript" language="javascript" src="//www.qb5200.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");
}
