How to assign array into variable in jquery

Question

The original and working array is this:

 var columns =[{
        name: 'level',
        minWidth: '200px'},
        {
        name: 'subject',
        minWidth: '70px'},
        {
        name: 'catid',
        minWidth: '70px'}],

However, I want to use if else statement to assign different array for different 'target' value. So I tried as below but it doesn't seem to supply the array correctly to the 'columns' variable.

 var useThis=[];
        if(target=="subject")
        {
            useThis = {
            name: 'level',
            minWidth: '200px'},
            {
            name: 'subject',
            minWidth: '70px'},
            {
            name: 'catid',
            minWidth: '70px'};

        }
        else
        {
            useThis = {
            name: 'level',
            minWidth: '200px'};

        }
var columns="["+useThis+"],";

How do I assign array correctly with if else statement?

var useThis=[];
        if(target=="subject")
        {
            useThis = [{  <---- Put here Opening bracket
            name: 'level',
            minWidth: '200px'},
            {
            name: 'subject',
            minWidth: '70px'},
            {
            name: 'catid',
            minWidth: '70px'}];  <--- Put here closing bracket

        }
        else
        {
            useThis = [{ <--- Put here opening bracket
            name: 'level',
            minWidth: '200px'}];  <--- Put here closing bracket

        }
var columns = useThis;

There's nothing wrong with the if-else statement itself. You have several problems in the rest of the code. You are assigning two different types of data (array of dictionaries or dictionary) depending on whether if or else is executed. Finally, you cannot just add string braces to your array when you assign useThis to columns.

var useThis=[];
    if(target=="subject")
    {
        useThis = [{
        name: 'level',
        minWidth: '200px'},
        {
        name: 'subject',
        minWidth: '70px'},
        {
        name: 'catid',
        minWidth: '70px'}];

    }
    else
    {
        useThis = [{
        name: 'level',
        minWidth: '200px'}];

    }
var columns = useThis;

I think you're missing the large brackets.

if(target=="subject")
        {
            useThis = [{
            name: 'level',
            minWidth: '200px'},
            {
            name: 'subject',
            minWidth: '70px'},
            {
            name: 'catid',
            minWidth: '70px'}];

        }

Here's how you'd use it, http://jsfiddle.net/gvmy9r8o/
