regex - JavaScript - Regular expression to convert image source -

-

my question related javascript regular expressions.

i'm building simple lightbox wordpress mootools javascript framework.

wordpress stores pictures in variety of sizes file names like:

'image-50-50x100.jpg' 'image-50-150x100.jpg' 'image-50-1024x698.jpg' 'image-50.jpg'

when user clicks thumbnail image, have convert source of image source of full size image, , preload full-size image.

the question

how change string this:

'http://some-path/image-50-50x100.jpg' 'http://some-path/image-50-150x100.jpg' 'http://some-path/image-50-1024x698.jpg' 'http://some-path/image-50.jpg'

, into:

'http://some-path/image-50.jpg'

missing piece accurate regular-expression in code below:

source.replace( /regular-expression/, '' );

thanks in advance.

this should it:

str = str.replace(/-\d+x\d+/, '');

e.g.:

var str = 'http://some-path/image-50-1024x698.jpg'; str = str.replace(/-\d+x\d+/, ''); console.log(str); // "http://some-path/image-50.jpg"

and case don't want change, doesn't:

var str = 'http://some-path/image-50.jpg'; str = str.replace(/-\d+x\d+/, ''); console.log(str); // "http://some-path/image-50.jpg"

edit: you've said in comment elsewhere that:

in rare cases can happen wordpress user uploads image image-1024x698.jpg, wordpress creates thumb image image-1024x698-300x300.jpg

okay, add \. , . above:

var str = 'http://some-path/image-1024x698-300x300.jpg'; str = str.replace(/-\d+x\d+\./, '.'); console.log(str); // "http://some-path/image-1024x698.jpg"
