我有这段代码,但是有些人在我的网站上的值可能会改变.我需要每30秒钟更新一次#finance div.这可以做吗
$(function() {
$.getJSON(
"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22%5EFTSE%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=?",function(json){
$('#finance').text(json.query.results.quote.Change);
// Patching payload into page element ID = "dog"
});
});
解决方法
您可以将代码放在单独的函数中,如下所示：
function LoadFinance()
{
$(function() {
$.getJSON(
"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20(%22%5EFTSE%22)%0A%09%09&format=json&env=http%3A%2F%2Fdatatables.org%2Falltables.env&callback=?",function(json){ $('#finance').text(json.query.results.quote.Change);
// Patching payload into page element ID = "dog"
});
});
}
setInterval( LoadFinance,30000 );
祝你好运！
