<script>
$(document).ready(function() {
$.get("index.json?" + new Date().getTime(), function(result) {
console.log(result);
setNewsList(result);
setNewsCates(result);
setNewsContent(result, T.getQueryString("id"));
});
});
function setNewsList(data) {
var htmlTemplate = "<div><a href='json.test.html?id={id}'>{title}</a></div>";
var list = $("#newsList");
for (var i = 0; i < data.length; i++) {
list.append(T.formatEx(htmlTemplate, data[i]));
}
};
function setNewsCates(data) {
var htmlTemplate = "<div><a href='json.test.html?cate={cat}'>{cat}</a></div>";

list.append(T.formatEx(htmlTemplate, data[i]));
output[data[i].cat] = true;
}
};
function setNewsContent(data, id) {
for (var i = 0; i < data.length; i++) {
if (data[i].id != id) continue;
$("#newsContentTitle").html(data[i].title);
$.get("news/" + id + ".html", function(result) {
