MVC中处理Json和JS中处理Json对象
ASP.NET MVC 很好的封装了Json,本文介绍MVC中处理Json和JS中处理Json对象,并提供详细的示例代码供参考。
MVC中已经很好的封装了Json,让我们很方便的进行操作,而不像JS中那么复杂了。
方法一
MVC中:
public JsonResult Test()
{
JsonResult json = new JsonResult{ Data = new{ Name = "zzl", Sex = "male",} }; // Name、Sex为可自定义的属性名
return Json(json);
}
public JsonResult TestList()
{
List<User> userList = new List<User>
{
new User{Name="zzl",Email="bfyxzls@sina.com"},
new User{Name="zhz",Email="zhanghangzheng@sina.com"},
};
JsonResult json = new JsonResult{ Data = userList };
return Json(json);
}
前台调用:
<script>
$.ajax({
url: "/Home/Test",
dataType: "json",
cache: false,
data: null,
type: "POST",
success: function (data) {
alert(data.Data.Name);
}
});
$.ajax({
url: "/Home/TestList",
dataType: "json",
cache: false,
data: null,
type: "POST",
success: function (data) {
var msg = "";
for (var i = 0, length = data.Data.length; i < length; i++) {
msg += "<DiV>Name:" + data.Data[i].Name + ",Email:" + data.Data[i].Email + "</div>";
}
$("#msg2").html(msg);
}
});
</script>
第二种 列表的方法
public JsonResult TestList()
{
List<User> userList = new List<User>
{
new User{Name="zzl",Email="bfyxzls@sina.com"},
new User{Name="zhz",Email="zhanghangzheng@sina.com"},
};
return Json(userList);
}
jq
$.ajax({
url: "/Home/TestList",
dataType: "json",
cache: false,
data: null,
type: "POST",
success: function (data) {
var msg = "<table border=1><thead><tr><td>Name</td><td>Email</td></tr></thead><tbody>";
for (var i = 0, length = data.length; i < length; i++) {
msg += "<tr><td>" + data[i].Name + "</td><td>"
+ data[i].Email + "</td></tr>";
}
msg += "</body></table>";
$("#msg2").html(msg);
}
});
注意看红色的部分,是否是更简单了呢!哈哈
纯JS进行操作:
var arr = [{ "name": "zzl", "sex": "男" }, { "name": "lr", "sex": "女"}];
for (var i = 0; i < arr.length;i++ ) {
document.write(arr[i].name);
}
