Hi there

I am trying to build a JavaScript regex to strip out the & from the key in this example:

c&.a.&activitymap.&page=https%3A%2F%2Fsitdev.online¤cy=eur

if there are any matches it would give this result:

c.a.activitymap.page=https%3A%2F%2Fsitdev.online¤cy=eur

What I have tried:

I have tried a several times to match these results but no luck with this regex:

([^=&]*(?:=[^=&]*&[^=&]*)?)&


Here is a reg ex example, but I need it to match every key/value not just the first 2:

regex101 debugger[^]

Thanks

Which flavor of Regular Expressions? I use only .net's version.

with native functions working on arrays, you have a solution :
begin_string = "the&vars&are&arg" ;
middle_string = begin_string.split('&') ; // all & are the separators, the coming array have each parts isolated ( separator & )
final_string = middle_string.join() ; // a new string is build by concatenation of the 'middle_string' members.

// final_string is "thevarsarearg"



or the string.replace function :

begin_string.replaceAll('&', '');  all '&' are 'empty chars' now

1 solution

How about:
RegEx
(?:([^&]+)&)

Hi Richard,
Thanks for your post. This solution strips out all the ampersands.
We want to get rid of the ampersands in the key, but not between the key and value:

the end result should look like this:

x=1&a.activitymap.page=https%3A%2F%2Fsitdev.onlineglobal.currency=eur&activitymap.page=https%3A%2F%2Fsitdev.onlineglobal

Let me know if you need more clarification?
