我有一段 JavaScript 显示当前温度,但它不会随着温度的变化而更新。有没有办法在计时器上更新 JavaScript 的那部分?
编辑:对不起,这是代码(不是我创建的)。
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script type="text/javascript">
// javascript will go here
$(function(){
// Specify the ZIP/location code and units (f or c)
var loc = '10001'; // or e.g. SPXX0050
var u = 'f';
var query = "SELECT item.condition FROM weather.forecast WHERE location='" + loc + "' AND u='" + u + "'";
var cacheBuster = Math.floor((new Date().getTime()) / 1200 / 1000);
var url = 'http://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent(query) + '&format=json&_nocache=' + cacheBuster;
window['wxCallback'] = function(data) {
var info = data.query.results.channel.item.condition;
$('#wxIcon').css({
backgroundPosition: '-' + (61 * info.code) + 'px 0'
}).attr({
title: info.text
});
$('#wxIcon2').append('<img src="http://l.yimg.com/a/i/us/we/52/' + info.code + '.gif" width="40" height="40" title="' + info.text + '" />');
$('#wxTemp').html(info.temp + '°' + (u.toUpperCase()));
};
$.ajax({
url: url,
dataType: 'jsonp',
cache: true,
jsonpCallback: 'wxCallback'
});
});
</script>
