Question

I’m attempting to find and replace a string of text, but it doesn’t seem to like when I reference a variable? It works fine if I hardcode the number in there, but returns

missing : after property id

if I try to reference a variable:

var text = "section-1 section_1 section[1]";
var cloneCount = 1;
var cloneUp = 2;
var array = {
  "section-"+cloneCount:"section-"+cloneUp, 
  "section_"+cloneCount:"section_"+cloneUp, 
  "section\\["+cloneCount:"section\["+cloneUp
};

for (var val in array) {
  text = text.replace(new RegExp(val, "gi"), array[val]);
  alert(text);
}

Hoping someone here can help?

Your array initialization is incorrect and should just cause a syntax error. You want this:

var array = { };
array["section-"   + cloneCount] = "section-"  + cloneUp;
array["section_"   + cloneCount] = "section_"  + cloneUp;
array["section\\[" + cloneCount] = "section\[" + cloneUp;

You can’t use an expression as a key in an object literal, if you need to use an expression to build the key then you have to use the o[...] = ... syntax.
