Javascript Ajax Get
Javascript Ajax Get
提问于 2013-03-26 04:38:24
我正在尝试让javascript加载和刷新实时数据。但我无法让它显示任何数据。
下面是我的代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<script type="text/javascript">
function updateStats() {
$.ajax({
type: 'GET',
url: "http://localhost/data.php",
dataType: 'json',
success: function(data) {
$('#sysstats').html(data.sysstats);
$('#aststats').html(data.aststats);
scheduleStatsUpdate();
},
error: updateFailed
});
}
function scheduleStatsUpdate() {
stats_timer = setTimeout('updateStats();',6000);
}
</script>
<body>
<div id="aststats" class="infobox ui-widget-content ui-corner-all">
</div>
<div id="sysstats" class="infobox ui-widget-content ui-corner-all">
</div>
</body>Data.php文件返回以下内容：

更改：
function scheduleStatsUpdate() {
stats_timer = setTimeout('updateStats();',6000);
}通过
(function scheduleStatsUpdate() {
stats_timer = setTimeout('updateStats();',6000);
})();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
