问题描述
我有这块code,但该值可能改变,而有人在我的网站。我需要每30秒左右更新#finance股利。可以这样做?
$(函数(){
$ .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=?",
功能(JSON){
$('#财经)文本(json.query.results.quote.Change);
//修补的有效载荷送入页面元素ID =狗
});
});
解决方案
您可以把您的code在这样一个单独的函数:
函数LoadFinance()
{
$(函数(){
$ .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=?",
功能(JSON){$('#财经)文本(json.query.results.quote.Change)。
//修补的有效载荷送入页面元素ID =狗});
});
}
然后设置一个定时器调用该函数每30秒:
的setInterval(LoadFinance,30000);
祝你好运! ;)
I have this piece of code, but the values may change while someone is on my site. I would need to update the #finance div every 30 seconds or so. Can this be done?
$(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"
});
});
解决方案
You can put your code in a separate function like this:
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" });
});
}
And then set up a timer calling the function every 30 seconds:
setInterval( LoadFinance, 30000 );
Good luck! ;)
