jquery - Manipulating a copied attr -

-

i'm working on simple lightbox script website, wraps link (a) around image. link url should src of image, manipulated.

the image url this: "pb028855_copy_147x110.jpg" , want delete "147x110", after "copy" before ".jpg" is.

my current script, copy src image link this:

$(function(){     $('img.withcaption').each(function(){         var $imgsrc = $(this).attr("src");         $(this).wrap('<a rel="lightbox" />');         $(this).parent().attr("href", ""+$imgsrc);     }); });

how can use parts of attr?

thank in advance...

if you're not numbers be, use replace()(docs) method regular expression.

$(function(){     $('img.withcaption').each(function(){         var $imgsrc = this.src.replace(/_\d+x\d+\./,'.');         $(this).wrap('<a rel="lightbox" />')                .parent().attr("href", ""+$imgsrc);     }); });

so this:

pb028855_copy_147x110.jpg

will end this:

pb028855_copy.jpg

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
