jquery ajax 简单范例(界面+后台)

界面:

<script> 
$(document).ready(function () { 
$("#b01").click(function () { 
htmlobj = $.ajax({ url: "/Content/upFile/测试.txt", async: false }); 
$("#div01").html(htmlobj.responseText); 
}); 
}); $(document).ready(function () { 
$("#test").load("/Content/upFile/测试2.txt #p1", function (responseTxt, statusTxt, xhr) { 
if (statusTxt == "success") 
alert("外部内容加载成功！" + xhr); 
if (statusTxt == "error") 
alert("Error: " + xhr.status + ": " + xhr.statusText); 
}); 
}); 
$(document).ready(function () { 
$("#getbutton").click(function () { 
$.get("/DownSet/index", function (data, status) { 
alert("数据：" + data + "\n状态：" + status); 
}); 
}); 
}); 
$(document).ready(function () { 
$("#postbutton").click(function () { 
$.get("/CustomerInformation/getS", { par: "ww" }, function (data, status) { 
alert("数据：" + data + "\n状态：" + status); 
$("#postText").html(data); 
}); 
}); 
}); 
</script> 
<div id="div04"> 
<h2 id="postText">post方法加载文本后 会在这里显示</h2> 
<input type="button" value="post方法获取" id="postbutton" /> 
</div> 
<div id="div03"> 
<h2 id="getText">get方法加载文本后 会在这里显示</h2> 
<input type="button" value="get方法获取" id="getbutton" /> 
</div> 
<div id="div02"> 
<h2>jquery load方法加载的显示在这里</h2> 
<h2 id="test">加载文本后 会在这里显示</h2> 
</div> 
<div id="div01"> 
<h2>加载文本后 会在这里显示</h2> 
</div> 
<p> 
<input type="button" value="加载文本" id="b01"/> 
</p>

后台:

public string getS(string par) 
{ 
string content = ""; 
if (par.Equals("ww")) 
{ 
content = "cheng gong le"; 
} 
else 
{ 
content = "shi bai le"; 
} 
return content; 
}
