将 JSON 与 Jquery Ajax 结合使用
今天早上我开始练习 Jquery AJAX JSON。我了解 Jquery，但了解 JSON & Ajax 对我来说是个新鲜事物。
我开发了一小段代码来使用 ajax 读取 JSON 文件并通过附加列表来显示数据值。
在正文部分使用以下 div。
<div id="tabPanelWrapper"></div>
Javascript：
$(document).ready(function() {
// Calling Ajax Function
loadContent();
});
function loadContent() {
$.ajax({
type: "GET",
url: "data.js",
dataType: "json",
cache: false,
contentType: "application/json",
success: function(data) {
alert("Success");
$.each(data.dashboard, function(i,post){
$('#tabPanelWrapper').append('<ul><li>' + data.id + '</li><li>' + data.name +'</li></ul>');
});
},
error: function(xhr, status, error) {
alert(xhr.status);
}
});
}
JSON 文件：
{
dashboard: [
{
"id": "tcm:20-1869",
"name": "FEATURED ARTICLE"
},
{
"id": "tcm:20-1869",
"name": "FEATURED ARTICLE"
}
]
}
页面抛出 404 错误。请帮我处理这段代码。

I started my hands on training on Jquery AJAX JSON this morning. I have knowledge of Jquery but JSON & Ajax is something new to me.
I have developed a small snippet of code to read JSON file with ajax and show the data values by appending the list.
using following div in body section.
<div id="tabPanelWrapper"></div>
Javascript:
$(document).ready(function() {
// Calling Ajax Function
loadContent();
});
function loadContent() {
$.ajax({
type: "GET",
url: "data.js",
dataType: "json",
cache: false,
contentType: "application/json",
success: function(data) {
alert("Success");
$.each(data.dashboard, function(i,post){
$('#tabPanelWrapper').append('<ul><li>' + data.id + '</li><li>' + data.name +'</li></ul>');
});
},
error: function(xhr, status, error) {
alert(xhr.status);
}
});
}
JSON File:
{
dashboard: [
{
"id": "tcm:20-1869",
"name": "FEATURED ARTICLE"
},
{
"id": "tcm:20-1869",
"name": "FEATURED ARTICLE"
}
]
}
Page is throwing 404 error. Please help me with this code.
Thanks in advance | Lokesh Yadav

404 错误是页面未找到错误。我会尝试浏览到您尝试访问的 data.js 文件，并且可能尝试在 .ajax 调用中写出该文件的完整 url。
即
如果那是您的脚本的位置。
更新
您的错误是无效的 Json。如果您检查错误函数中的错误参数，您就会看到这一点。
尝试在仪表板周围添加引号，您应该更进一步！
而且您还必须更改您的成功方法：
请注意，我正在查看
post.id和post.name因为这是$.each 枚举。 data.id 会在 Json 中的仪表板旁边查找 id 属性，但该属性不存在。a 404 error is a Page Not found error. I'd try to browse to the data.js file you're trying to access, and maybe try to write out the full url to the file in your .ajax-call.
I.e.
if that's the location of your script.
UPDATE
Your error is invalid Json. If you check the error argument in your Error-function, you'd see that.
Try adding quotes around dashboard, and you should be one step further!
And you'll also have to change in your success-method:
note that I'm looking at
post.idandpost.namesince that is the current item in the $.each enumeration. data.id would look for an id-property next to dashboard in your Json, but that doesn't exist.更改
为
404 错误肯定不是由此引起的。
change
to
defnitely the 404 error is not due to this.
检查 URL 属性。
404 错误不是 json 错误。
Check the URL property.
An 404 error is not a json error.
