I have created an array: 

var endFlowArray = new Array;
for (var endIndex in flowEnd) { // <- this is just some numbers 
    for (var i in dateflow) { // <- same thing 
        var check = $.inArray(flowEnd[endIndex], dateflow[i]);
        if (check >= 0) {
            endFlowArray.push(i);
            flowEnd[endIndex] = null;
        }
    }
}

how can i convert a string array : 

["286", "712", "1058"]

to integer array : 

[286, 712, 1058]

It's an easy fix. .push(+i) or .push(parseInt(i)). Simply converting a string to an integer. –  Kevin B May 10 '12 at 20:39

my endFlowArray came up with something like this You need to explain this statement. How did it "come up"? Are you using a javascript debugger? alert? Something else? –  Chris May 10 '12 at 20:40

is dateflow an array of strings or numbers? –  gdoron May 10 '12 at 20:41

Strings in the console are symbolized by wrapping them in quotes. By that fact, we can assume that i is a string. Convert it to an integer and it will no longer be a string and no longer have those quotes.

endFlowArray.push(+i);

Your "numbers" in flowEnd and dateFlow are actually strings, not numbers.
