Question

I basically have the following string in the format:

A,B,C:D,E,F

What I am trying to achieve is a means of pairing up left hand side JavaScript variable, to the left of the “:” with the right hand side values to the right of the “:”

I would like to have the following variables set in, so that I can use in my coding, i.e:

var A = D;
var B = E;
var C = F;

I can then use the values of A,B and C as parameters into other JavaScript functions.

I have looked at the split and slice methods for this string manipulation but unsure how to pair up left hand side with right hand side values.

Answer 1

With this method (attaching variables to an object), you can reference variables in code without an eval statement.

a = "A,B,C:D,E,F";
array = a.split(":"); //split on the colon, get two strings
lefts = array[0];
rights = array[1];

obj = {} //object to attach variables to.
for( var i = 0; i < lefts.length; i++ )
{
  obj[lefts[i]] = rights[i]; //set the member variables of obj
}

obj.A // D
obj.B // E
obj.C // F

If you care about the wasted comma property, check if lefts[i] is equal to a comma before you set on the object.
