I am having a JavaScript array and I want to convert this array into string with a separator, in a way PHP implode does.

e.g.

var daysArr = [];
daysArr.push('monday');
daysArr.push('tuesday');

I want to get "monday*tuesday"

How can we achieve this?

Thx.

Try using this

daysArr.join('*');

NameOfArray.join('separator');

I tried doing that, but there is a constraint in place which says you can accept answer after 5 minutes –  Jatin Dhoot Jul 6 '11 at 12:34
    
Hmm, how strange. Probably a good thing in case better answers appear. –  JLevett Jul 6 '11 at 12:42

Use JavaScript function join 

daysArr.join('*');

var arr = new Array();
arr[0] = "1";
arr[1] = "2";

alert(arr.join("*"));

This function should do it

<script>
var daysArr = [];
daysArr.push('monday');
daysArr.push('tuesday');

function implode(arr, sep) {
    //Output string
    output = '';
    //Counter
    j = 1;
    for (i in arr) {
        //Append
        output += arr[i];
        //Add seperater if not the last item
        if (j != arr.length) {
            output += sep;
        }
        j++;
    }
    //Return output
    return output;
}

alert(implode(daysArr, ','));
</script>

Oops, forgot about the join function! –  fin1te Jul 6 '11 at 12:27
    
Yup, we need not write this big heap of code, if it offered as default. Good try though –  Jatin Dhoot Jul 6 '11 at 12:35
