首次加载页面时，然后在时间段之后执行jQuery代码

Question

I have a piece of jQuery code and I need to execute when page load for first time, then I need to execute the same code after 30 minutes (less take this value as example) of course if page is open. I know how to execute code every 30 minutes by using this:

window.setInterval(function() {
    ...
    });
}, 1800000); // Updates each 30 minutes

But which is the best approach to do this, I mean execute code first time page loads and then every 30 minutes, do I explain myself?

Answer 1

Put your function into a name func:

function blah() {
...
}

Then call it:

window.setInterval(blah, 18000000);
blah();

Answer 2

$(window).load(function () {
    function func() {
        //code here
    }
    func(); // call the function window.load 
    window.setInterval(func, 1800000); // also set setInterval to run function func .
});

or

$(document).ready(function () {
    function func() {
        //code here
    }
    func(); // call the function window.load 
    window.setInterval(func, 1800000); // also set setInterval to run function func .
});

Answer 3

Or just

(function() {
    // Your code

    // Then call itself again
    setTimeout(arguments.callee, 18000000);
})()
