My JavaScript code is this:
var i=0;
var ret=[];
ret[i][0]=newID;
ret[i][1]=jobTitle;
ret[i][2]=jobText;
ret[i][3]=jobEmail;
ret[i][4]=jobOrder;
These are all strings and all have value. I'm getting the error:
"Uncaught TypeError: Cannot set property '0' of undefined" on the first assignment: ret[i][0]=newID;
Also error at jsfiddle http://jsfiddle.net/Zf9rE/2/
what am I doing wrong?
You must create ret[i] before you try to add elements to it:
var i=0;
var ret=[];
ret[i] = []; // define ret[i]
ret[i][0]=newID;
ret[i][1]=jobTitle;
ret[i][2]=jobText;
ret[i][3]=jobEmail;
ret[i][4]=jobOrder;
Unless there is a reason to hard code the array indexes, you might prefer to either create an array literal (as @Rocket shows in the comments) or use Array.prototype.push():
ret[i].push(newID);
ret[i].push(jobTitle);
Another aproach:
var jobTitle="j title";
var jobText = "j desc";
var jobEmail="jemail";
var jobOrder="j order";
var newID="3";
var i=0;
var ret = new Array();
var matrix = new Array()
ret[0]=newID;
ret[1]=jobTitle;
ret[2]=jobText;
ret[3]=jobEmail;
ret[4]=jobOrder;
matrix[i] = ret;
console.log(matrix[0][0]);
