replace double slash in javascript

Question

I'm working in a javascript function, in a given string I need to replace // for only one slash / by now I have:

result= mystring.replace("\/\/", "/");

bt it's not working, I still get the string with double slash, so which is the proper regex to indicate the double slash to the replace function?

I already tried:

• !//!
• ////
• ///g///g

Edit: I'm using it to correct a URL that is saved in the string, for example, sometimes that URL can be something like: mywebpage/someparameter//someotherparameter and that double slash gives problem, so I need to replace it to one single slash like: mywebpage/someparameter/someotherparameter

Answer 1

Use regex /\/\//(or /\/{2}/) with a global modifier to replace all occurrence.

result= mystring.replace(/\/\//g, "/");

console.log(
  'hi// hello//123//'.replace(/\/\//g, '/')
)
