javascript - How to access to dynamic key stored with JQuery data -

i stored info of key value within html element using following:

$('#newitem').data("metadata", data);

this info contains few keys name img0 img1 img2 img3

the number of images not know in advance , i'm getting in key number of images exist in key value data.

i'm trying loop on stored info , pull these value not working:

for ( var = 0; < numofpic; i++ ) { var img = $(item).data("metadata").itempic+i; }

is there way convert itempic+i key can use?

you can utilize square brackets suggested @hindmost:

var images = $(item).data("metadata"), itempic = 'img'; ( var = 0; < numofpic; i++ ) { var img = images[itempic+i]; // or images["img" + 1] }

and practice run dom search 1 time , cache search instead of doing search every iteration of loop.
