ViewsCannot replace all ^ symbol to 25%5E
I have replace the problem in react. I want ^ to 25%5E, but I just can replace one of ^ in the string, cannot replace all ^ symbol to 25%5E. Below is my sample code:
var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replace("^", "25%5E");
console.log(newUrlStr);Error Result:
Hope someone can guide me on how to solve this problem. Thanks.

You should use replaceAll which is for replacing all matched strings
var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replaceAll("^", "25%5E");
console.log(newUrlStr);You also can use regex with /g (a global flag) to have similar behaviour
var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replace(/\^/g, "25%5E");
console.log(newUrlStr);0
use regex to find all occurence of ^ and replace.
var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replace(/\^/g, "25%5E");
console.log(newUrlStr);0
Use the replaceAll() method
var urlStr = "http://localhost:3005/branch-management/edit-branch/?companyName=ABC%20SDN%20BHD%20!!!!%40%40%40%40%23%24%^%26*()&branchName=ABC%20!%40%23%24%^%26*()_";
var newUrlStr = urlStr.replaceAll("^", "25%5E");
console.log(newUrlStr);
the replace method either takes a pair of char's or a pair of CharSequence's (of which String is a subclass, so it'll happily take a pair of String's).
The replace method will replace all occurrences of a char or CharSequence. On the other hand, the first String arguments of replaceFirst and replaceAll are regular expressions (regex). Using the wrong function can lead to subtle bugs.
