Javascript push

Question

I'm trying to push multiple values into an array.

When I use:

csvData.push('data[0][index],data[1][index],data[2][index],data[3][index]');

it formats it corrects so that

csvData[0] = "data[0][index],data[1][index],data[2][index],data[3][index]"
csvData[1] = "data[0][index],data[1][index],data[2][index],data[3][index]"
etc

Also when it evolves into a csv, it is correct in the 4 columns.

However when I use no quotes:

csvData.push(data[0][index],data[1][index],data[2][index],data[3][index]);

I get the values I want, but it's single dimensional.

csvData[0] = 23
92
74
22
etc

instead of

csvData[0] = 23,92,74,22

How can I add values it correctly?

What do you want the value of each element of csvData to be? An array? A string? — Felix Kling

You can create an array and push that:

csvData.push( [ data[0][index],data[1][index],data[2][index],data[3][index] ] );

The added brackets ([ ]) around the list of values creates an array, and that in turn is what's pushed onto the csvData array.

Ahh, Added the brackets and we're good. I tried join() and that also worked. Thx!

Put them inside an array and join them using join() method then push it.

csvData.push([data[0][index],data[1][index],data[2][index],data[3][index]].join());

if you want multidimentional than use

csvData.push([data[0][index],data[1][index],data[2][index],data[3][index]]);
