Question

I have a string in Javascript and i want to add something to it when a checkbox is checked and the submit button is activated.

What i have is this:

var strDimensions = ["Sex","Age"]; 

$("input[id='Class']:checked").each(function() {
            strDimensions += "Class"; 
    }       
);

var chart = d3.parsets().dimensions(strDimensions);

The only thing thats not working is adding up Class to the string.

i want strDimensions to be this when the checkbox is checked:

strDimensions = ["Sex","Age","Class"];

Answer 1

Don’t you mean Array.push?

strDimensions.push("Class");
