Javascript | For loop - What is my syntax error?

Javascript/JQuery

    var gallerynr = 3;
    var thumbsnrA = new Array(gallerynr);

    var a = 0;
    var b = 0;
    var d = 0;

    for (d = 0; d == gallerynr; d++) {
        thumbsnrA[a] = 22;
        a ++;
        b ++;
    };

    alert(thumbsnrA);

Result (should be):

22,22,22

But my Result is:

What is wrong with the syntax of m开发者_JAVA技巧y code?

You test is wrong.

for (d = 0; d < gallerynr; d++) {

is what you want

If you have

for (d = 0; d == gallerynr; d++) {

it only runs when d is 3 and it is not 3 from the beginning

Your array variable is declared as thumbsnr, but you reference thumbsnrA later on in the code.

Edit - OK, so you've changed your code! There is a misplaced semi-colon after your loop - that could be throwing the error.

You don't need a delimiter after the closing brace of the for loop, and if d!=gallerynr before the loop, then the for loop will never be entered.
