Hello I have a JSON array data.cells that I need to iterate through to get the values out of and put the values into an onclick event listener.

Right now the variable name data.cells.letter is being based through the buildString function for each cell in my board, instead of the value of the variable. Same goes for the x and y variables.


for(var i = 0; i < data.cells.length; i++) {
			var x = i % 4 + 1;
			var y = 0;
			if(i < 4) {
				y = 1;
			}
			else if(i < 8) {
				y = 2;
			}
			else if(i < 12) {
				y = 3;
			}
			else {
				y = 4;
			}
			document.getElementById('t' + i).addEventListener('click',function(data){
				buildString(this, data.cells[i].letter, x, y);}, false);
			document.getElementById('t' + i).setTextValue(data.cells[i].letter);
		}

I have no idea what you're trying to do, you're already are passing those variables to the function.

buildString(this, data.cells[i].letter, x, y);

So when the buildString function gets called instead of some value for data.cells.letter like 'A' the string data.cells.letter is being passed to the function. I want to get what the value of data.cells.letter is.

This might get what you need. An example of passing the arguments ( or parameter ) to another function.
