Change part of a string with jQuery

I'm sure this is something simple, but I can't figure it out.

I have this HTML:

<img src="/7290/9200572193_f95fb66c50_m.jpg" />

Which I need to change to

<img src="/7290/9200572193_f95fb66c50_b.jpg" />

This isn't always the same image, but the _m.jpg and _b.jpg are. How can I do this with jQuery?

In short, use.replace. Such as:

"/7290/9200572193_f95fb66c50_m.jpg".replace('_m.jpg', '_b.jpg');
/*  OR  */
var url = "/7290/9200572193_f95fb66c50_m.jpg";
url.replace('_m.jpg', '_b.jpg');

You use .each() in jQuery to loop through a group of elements. Thus you can use a simple selector like $('img') to select all images on the view and then make changes in the callback method. You would then use .prop to both set and get the current src and change it using old fashioned .replace

$("img").each(function(i) {
    $(this).prop("src", $(this).prop("src").replace('_m.jpg', '_b.jpg'));
});

Loop through "img" tags with $("img").each(function(){ doStuff(); });. Change attributes with attr("attribute","new_value"), get attributes with attr("attribute"). Replace with replace("from","to").

$("img").each(function(){
  $(this).attr("src",$(this).attr("src").replace("_m","_b"));
});

Something like this may help you:

$( "img" ).each(function() {
  var src = $( this ).attr( "src" );
  $( this ).attr( "src", src.replace( /_m\.(.*)$/, "_b.$1" ) );
});

This will not depend on the extension of your src attribute.

You can do:

var imgSrc = "/7290/9200572193_f95fb66c50_m.jpg";
imgSrc = imgSrc.replace("_m.jpg", "_b.jpg");
