Replace substring containing '+'

I have a string with sub-string '5+' and it looks like sales/100/5+. I need to remove the sub-string 5+.

Input : sales/100/5+

Demanded output : sales/100

The jquery script is as follows:

var rstring = 'sales/100/5+';
if((splitStr == '5+')||(splitStr == '4-')) {
    var key = rstring.replace(new RegExp('/'+splitStr, 'g'),"");
    alert(key);
}

Now im getting the result : sales/100+

But desired output is : sales/100

You don't really need to use a Regex to make your string replace work

the simplest the best :

  var rstring = 'sales/100/5+';
  if((splitStr == '5+')||(splitStr == '4-')) 
  {
       var key = rstring.replace('/' + splitStr, '');
       alert(key);
  }

the '+' in your Regex is a quantifier. It matches between one and unlimited times, as many times as possible, giving back as needed. That's why your + was still ther after your replace.

You can remove /5+ from given strings. No jQuery code is neede, just a simple JS function.

function replace5plus(str) {
    return str.replace('/5+', '');
}

To achieve this you can split() the string by /, remove the last element, then join() it back together, like this:

var arr = 'sales/100/5+'.split('/');
arr.pop();

console.log(arr.join('/'));
