Docs. For all occurrences to be discarded use:
PS: The replace function returns a new string and leaves the original string unchanged, so use the function return value after the replace() call.

2 This doesn't have anything to do with jQuery. You can use the JavaScript
You can also pass a regex to this function. In the following example, it would replace everything except numerics:

Here are some examples showing how it works:

ARCARC 1,02314 silver badges31 bronze badges 0 I was used to the C# (Sharp) String.Remove method. In Javascript, there is no remove function for string, but there is substr function. You can use the substr function once or twice to remove characters from string. You can make the following function to remove characters at start index to the end of string, just like the c# method first overload String.Remove(int startIndex):
and/or you also can make the following function to remove characters at start index and count, just like the c# method second overload String.Remove(int startIndex, int count):
and then you can use these two functions or one of them for your needs! Example:

Brett DeWoodyBrett DeWoody 56.7k28 gold badges134 silver badges183 bronze badges Another way to replace all instances of a string is to use the new (as of August 2020) It accepts either a string or RegEx as its first argument, and replaces all matches found with its second parameter, either a string or a function to generate the string. As far as support goes, at time of writing, this method has adoption in current versions of all major desktop browsers* (even Opera!), except IE. For mobile, iOS SafariiOS 13.7+, Android Chromev85+, and Android Firefoxv79+ are all supported as well. * This includes Edge/ Chrome v85+, Firefox v77+, Safari 13.1+, and Opera v71+ It'll take time for users to update to supported browser versions, but now that there's wide browser support, time is the only obstacle.

zcoop98zcoop98 2,4041 gold badge17 silver badges29 bronze badges Make sure that if you are replacing strings in a loop that you initiate a new Regex in each iteration. As of 9/21/21, this is still a known issue with Regex essentially missing every other match. This threw me for a loop when I encountered this the first time:
If you try and do it like so, don't be surprised if only every other one works
