Thread: javascript array enquiry

a tiny bit of background:

have 2 arrays - 1 parent , 1 child, if will.

child subset of parent.

parent array:

code:

parent=new array() parent[0]=image1; parent[1]=image2; parent[2]=image3; parent[3]=image4; parent[4]=image5; parent[5]=image6;

child array:

code:

child=new array() child[0]=parent[0]; child[1]=parent[3]; child[2]=parent[4];

each image "value" (in parent array) has unique parameters - e.g. horizontal vs. vertical orientation - address in third array. when images selected - web-based thumbnail gallery (which made of parent or child subset of images) - (larger) image displayed proper positioning , orientation.

the central issue:

searching way access index number of parent "value" within child array - i.e. "3" within parent[3] - number keyed formatting characteristics (of image4, example) defined within 3rd array.

suggestions.

store id image , use id lookup in third array. or better, store information of third array image third array no longer needed.
