How to change array all values in javascript by button click event?

Question

I have one array as below in JavaScript :

Actual array in JavaScript: array('123456' => '1', '456789' => '0', '789123' =>'1', '4456784' => '0', 'so on...' => '0');

Wanted result array in JavaScript: array('123456' => '1', '456789' => '1', '789123' =>'1', '4456784' => '1', 'so on...' => '1');

Is there any way to change JavaScript array all values as fix like 1 or 0(In wanted result array) without using any loops like(for, .each, etc...).

Please suggest any idea if there is any possibilities in this. Thank you in advance!

You're showing a PHP array in a Dictionary form, Javascript doesn't support Dictionary (yet). — haim770

JS supports dictionary as objects... The solution is a loop... Why don't you want to use a loop to do the loop job ? You could use a function that do a loop :D — Loenix

Use objects as dictionaries. Creating this object with Object.create(null) helps. And you need to use a for in loop to process it. — Aravind

There are 1092 elements in array, and maybe it can increase more then this, so is not loop takes more time? So i need shorter way then loop to assign same value in all elements of array. — b03Developer

you can define your array in javascript:

var arrayData = new Array({'key':'123456','value':'1'}, {'key':'456789','value':'0'},{'key':'789123','value':'1'}, {'key':'4456784','value':'0'});

and use array like that :

 $.each(arrayData, function(index,data){
     alert(arrayData[index].key);
     alert(arrayData[index].value);
 })

and set value in array according to your condition.

Suppose I have javascript array like you gave,

var arrayData = new Array({'key':'123456','value':'1'}, {'key':'456789','value':'0'},{'key':'789123','value':'1'}, {'key':'4456784','value':'0'});

And now if i wanted replace its value without using $.each, then how can it be?

apply check on key and change its value accordingly. like : arrayData[index].value = 10
