Trying to put the value of a variable into a function parameter

May 26th, 2009

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

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

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