You can do exactly what you have :)
var string = "|0|0|0|0";
var newString = string.replace('|','');
alert(newString); // 0|0|0|0
You can see it working here, .replace()
in javascript only replaces the first occurrence by default (without /g
), so this works to your advantage :)
If you need to check if the first character is a pipe:
var string = "|0|0|0|0";
var newString = string.indexOf('|') == 0 ? string.substring(1) : string;
alert(newString); // 0|0|0|0?????????????????????????????????????????
