Question

//PROBLEM SOLVED// It turned out that the JQuery Ajax call couldn't reach the URL in certain browsers.

Thanks anyway guys, for your quick responses, definitly helped to work it out.

Sorry for the non-specific title, I don't even think what should be the problem.

There is a JQuery plugin ( http://keith-wood.name/countdown.html ) which counts down from a specific date or time.

The end time from which the counter should start can be defined in 2 ways: either setting a date either setting the number of seconds left.

My project needs the second one and based on the documentation this option has to be declared like:

$('#digital_hour').countdown({until: +300});

Notice the "+" sign before the number.

It works nice on any OS and device, UNTIL I replace the number 300 with a variable that stores the seconds left until the end of the day on the server. So this version:

$('#digital_hour').countdown({until: +seconds_left_on_server});

works on specific browsers, but on others don't. Strangly enought it works under my Vista/Mozilla20.0 combo, but it doesn't on my Vista/IE6, nor on my friends Ubuntu/Mozilla combo.

I'm not a huge javascript admirer, nor an expert on the subject, but I feel that there is something around the "+" sign.

Can anyone help?

Answer 1

您可以尝试

$('#digital_hour').countdown({until: new Date(+(new Date()) + 1000 * seconds_left_on_server)});

Answer 2

Have you tried something simple like var seconds_left = 300 and then $('#digital_hour').countdown({until: +seconds_left}); and see what happens?

It sounds like your variable is not storing what it should. The "+" shouldn't be a problem.
