对Jquery中的ajax再封装,简化操作示例
代码如下:
<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "https://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
<html xmlns="https://www.w3.org/1999/xhtml">
<head>
<title>jqueryajaxjson取值示例</title>
<script type="text/javascript" src="scripts/jquery-1.4.4.min.js"></script>
<script type="text/javascript">
$(function () {
jsonajax("ajaxquery.x", "type=json", "json", callback);
jsonajax("ajaxquery.aspx", "id=1&name=2&type=text", "text", callbacktxt);
});
function callback(data) {
$("#ddd").html('');
var json = eval(data); //数组
$.each(json, function (index, item) {
//循环获取数据
var name = json[index].name;
var age = json[index].age;
var sex = json[index].sex;
$("#ddd").html($("#ddd").html() + "<br>" + name + " " + age + " " + sex + "<br/>");
});
};
function callbacktxt(data) {
$("#ccc").html(data);
};
/**
* ajax post提交
* @param url
* @param param
* @param datat 为html,json,text
* @param callback回调函数
* @return
*/
function jsonajax(url, param, datat, callback) {
$.ajax({
type: "post",
url: url,
data: param,
datatype: datat,
success: callback,
error: function () {
jquery.fn.mbox({
message: '恢复失败'
});
}
});
}
</script>
</head>
<body>
<span id="ccc"></span>
<span id="ddd"></span>
</body>
</html>
。 代码如下:
using system;
//新增
using system.web.script.serialization;
using system.collections.generic;
public partial class ajaxquery : system.web.ui.page
{
protected void page_load(object sender, eventargs e)
{
if (!ispostback)
{
//数据模拟,仅供参考
string messgage = string.empty;
string id = request["id"];
string name = request["name"];
string gettype = request["type"];
if (gettype=="text")
{
messgage = (id == "1" && name == "2") ? "ok符合条件" : "sorry不符合条件";
}
else if (gettype == "json")
nbsp; {
list<student> list = new list<student>();
for (int i = 0; i < 50; i++)
{
student a = new student();
a.name = "张三" + i;
a.age = i;
a.sex = "男";
list.add(a);
}
messgage = new javascriptserializer().serialize(list);
}
else
{ }
response.write(messgage);
response.end();
}
}
public struct student
{
public string name;
public int age;
public string sex;
}
}
