jquery - Javascript remove commas from string -

-

this question has answer here:

i have below variable in javascript. want remove "comma" sign using jquery /javascript.

 var test = ",,2,4,,,3,,3,,,"  expected output: var test = "2,4,3,3"

please advice

use replace() regex 

var test = ",,2,4,,,3,,3,,,";    document.write(test.replace(/,+/g,',').replace(/^,|,$/g,''));

  1. replace(/,+/g,',') - remove multiple comma one.
  2. replace(/^,|,$/g,'') - remove comma @ starting , ending.
