How do you call a function with arguments repeatedly with setInterval()?

Question

My function runs correctly once but I want it to run repeatedly:

$('button').click( function(){

    setInterval(magicWords(7,3), 1000); 

});

I tried hardwiring the parameters in the function itself and running it parameter-less, but still its a no go...?

You could also use `setInterval(magicWords.bind(this, 7, 3), 1000);` — Ian, Jun 27 '13 at 05:27

You can do this way.

$('button').click( function(){

    setInterval(function(){
        magicWords(7,3)
     }, 1000); 

});

When you do setInterval(magicWords(7,3), 1000); it invokes the function as it executes the statement and effectively the result of your function (probably undefined if it does not return anything) will be set to run at that interval not the function itself. ou can use

And of-course if you are ready to add a shim for support for earlier browsers you can use ecmaScript 5 function.bind. This will bind y our function with specified context and parameters whenever invoked.

setInterval(magicWords.bind(this, 7,3), 1000);

Use closure:

setInterval( function(){ magicWords(7,3); }, 1000);
