How to replace substring in Javascript?

To replace substring.But not working for me...

var str='------check';

str.replace('-','');

Output: -----check

Jquery removes first '-' from my text. I need to remove all hypens from my text. My expected output is 'check'

replace only replace the first occurrence of the substring.

Use replaceAll to replace all the occurrence.

var str='------check';

str.replaceAll('-','');

Try this instead:

str = str.replace(/-/g, '');

.replace() does not modify the original string, but returns the modified version.
With the g at the end of /-/g all occurences are replaced.

simplest:

str = str.replace(/-/g, "");

You can write a short function that loops through and replaces all occurrences, or you can use a regex.

var str='------check';

document.write(str.replace(/-+/g, ''));

str.replace(/\-/g, '');

The regex g flag is global.
