查找并用Javascript替换href值中的任何数字

Question

This is my current code, which does not work:

$( "#cart_url" ).attr('href', this.href.replace( "ProductCode=TFLG1&Qty.TFLG1="/^[0-9]+$/"&", "test" ));

I'm not exactly sure how to write the syntax. Where I have "/^[0-9]+$/" , I'm just trying to replace any result of any number with "test".

Further information:

$( "#cart_url" ).attr('href', this.href.replace( "ProductCode=TFLG1&Qty.TFLG1=345&", "test" ));

This code would work fine, but the number '345' could be anything from 1-1000, so I need to find and replace that number dynamically instead of writing this function 1000 times.

If I understood correctly, the pattern you need is something like /[Qty.TFLG1][\\d]+(?=&)/g

It would work this way:

var pattern =/[Qty.TFLG1][\d]+(?=&)/g;
$("#cart_url").attr("href", this.href.replace( pattern, "test" ));

That would return something like:

ProductCode=TFLG1&Qty.TFLG1=test&
