Javascript array undefined in for loop

Question

I have a problem with a javascript array: \"arrFinal[i] is undefined\"

In my script arrFinal is dynamically generated

function fillTextareas () {
var         


        

Answer 1

It looks like an off-by-one error in the outer loop.

It should be i < tailleArrFinal, not <=.

Answer 2

By looking at your loop I can see at least 2 errors: you miss "var" and ".length" (you have to test for array length!)

try to replace:

for(i=0;i<=tailleArrFinal;i++){
        for(j=0;j<tailleArrSubFinal;j++) {
            $("form textarea#t" + i + "_" + j).val(arrFinal[i][j]);
        }
    }
}

with:

for(var i=0;i<tailleArrFinal.length;i++){
        for(var j=0; j<tailleArrSubFinal.length; j++) {
            $("form textarea#t" + i + "_" + j).val(arrFinal[i][j]);
        }
    }
}
