javascript - Select image by default on page load -


I have a JSON feed and I have the values ​​to populate a selection menu with product size, color / thumbnail Extract and submit the value in an object.

What I want, is to select an image by default, if its title matches the value of a declared variable and has been started at the top (like < Code> var initialColour = "wheat"; ). So if the initial color is "brown", the image titled "brown" should be selected by default and should reflect the size selection in the dropdown menu.

This is what I am trying to: 

  if (main img.reiter ('title') == initial collar) {$ (this) .addClass (" Active "); }

This is on the 27th line on the jsfiddle link below.

I appreciate any indication of the structure, I know its a mess.

What do you want to do?
I have changed some code in two places, I have left an original reference there. Actually, I have fixed the image directly to mainImg . Then use that, even when adding the class, besides, you missed some ' s in the image html: 

  $ ("& lt; img src = "+ BuildImageURL (mainImgID) +" id = "+ MainImgID +" class = 'colorhumb' title = "+ color +" data-value = '"+ color +"' & gt; ")

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
