我正在尝试制作一个自动刷新json,它每5秒重新加载一次更改。它在加载时第一次完全加载,但我的setinterval无法正常工作。这是每5秒钟,但即使已经进行了更改,它也不会更新我的菜单? 。
这是我到目前为止所得到的:
$(document).ready(function(load) {
var dmJSON = "example.com";
$.getJSON( dmJSON, function(data) {
setInterval(function () {
$(news).html("");
$.getJSON();
}, 5000);
var html = '';
// loop through all the news items, and append the
// title and published date to the html variable.
for(var i = 0; i < data.feed.data.length; i++){
html += '<div style="width: 600;direction: rtl;background-color: white;padding: 12px 12px 0;border: 1px solid;border-color: #e5e6e9 #dfe0e4 #d0d1d5;border-radius: 4px;margin-bottom: 20px;color: black;">';
html += '<span style="/* text-align: left; */direction: rtl;position: absolute;left: 250px;"> ' + data.feed.data[i].created_time + ' </span><span><img alt="" src="http://icons.iconarchive.com/icons/gakuseisean/ivista-2/128/Network-Globe-Disconnected-icon.png" style="background-size:auto;background-repeat: no-repeat;display: inline-block;height: 20px;width: 20px;position: absolute;left: 490px;padding-top: 9px;" /></span>' ;
html += '<br>' ;
html += data.feed.data[i].message ;
html += '<p><img alt="" src=' + data.feed.data[i].picture + ' /></p>';
html += '</div>';
}
// append all the html variable to the ticker div.
$("#news").append(html);
});
});
我使用此代码,但在刷新时,他会给我的空页
setInterval(function () {
$(news).html("");
$.getJSON();
}, 5000);
答案 0 :(得分:1)
试试这个:
$(document).ready(function(load) {
var dmJSON = "https://";
function fetch() {
$.getJSON( dmJSON + (+new Date()), function(data) {
$("#news").html('');
var html = '';
// loop through all the news items, and append the
// title and published date to the html variable.
for(var i = 0; i < data.feed.data.length; i++){
html += '<div style="width: 600;direction: rtl;background-color: white;padding: 12px 12px 0;border: 1px solid;border-color: #e5e6e9 #dfe0e4 #d0d1d5;border-radius: 4px;margin-bottom: 20px;color: black;">';
html += '<span style="/* text-align: left; */direction: rtl;position: absolute;left: 250px;"> ' + data.feed.data[i].created_time + ' </span><span><img alt="" src="http://icons.iconarchive.com/icons/gakuseisean/ivista-2/128/Network-Globe-Disconnected-icon.png" style="background-size:auto;background-repeat: no-repeat;display: inline-block;height: 20px;width: 20px;position: absolute;left: 490px;padding-top: 9px;" /></span>' ;
html += '<br>' ;
html += data.feed.data[i].message ;
html += '<p><img alt="" src=' + data.feed.data[i].picture + ' /></p>';
html += '</div>';
}
// append all the html variable to the ticker div.
$("#news").append(html);
});
}
setInterval(fetch, 5000);// call fetch every 5 seconds
fetch(); // call fetch first time
});
