javascript - Replace first character of string

Question

I have a string |0|0|0|0

but it needs to be 0|0|0|0

How do I replace the first character ('|') with (''). eg replace('|','')

(with JavaScript)

Answer 1

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?????????????????????????????????????????
