regex - How to replace src with regular expression and jquery -

-

i have following output. 

<img width='70' height='70' class='centreimg' src="http://localhost/aktivfitness_new/assets/images/centre/centre1.jpg" />

there same outputs centre2.jpg etc. want replace centre1.jpg hover.jpg when hover.

but when use following becomes centre1hover.jpg

 $(".centreimg").mouseover(function() {         var hoverimg = $(this).attr("src").match(/[^\.]+/) + "hover.jpg";         ...

something wrong match(/[^.]+/) + "hover.jpg part. how can this?

thanks in advance.

don't think easier:

var newsrc = oldsrc.replace(/[^\/\.]+\./, 'hover.');

anyway: shouldn't use javascript hovers =) if there way: use it. not bad practice, it's not user friendly: when image loads when hover, user see 'flash' because entire image still has loaded = not pretty.
