Question

The preg_replace function in PHP provides a limit parameter. For instance, the first occurrence of medium replace with original, and the second occurrence of medium replace with “type”.

$path = "demo\/medium\/Web081112_P001_medium.jpg";
$path = preg_replace ("/medium/","original",$path,1);
$path = preg_replace ("/medium/","type",$path,2);
echo $path;
// output : demo\/original\/Web081112_P001_type.jpg

So, are there any way using JQuery/ JavaScript to implement similar function? Thanks

Use JavaScript’s native replace().

By default, replace() will only replace the first occurrence – unless you set the g modifier.

Example:

path = "demo/medium/Web081112_P001_medium.jpg";
path = path.replace("/medium/", "original");
path = path.replace("medium", "type");
