You can use regex:
var matches = /Price:(.*?) /g.exec("Price:$20 is very cheap");
if(matches.length > 1) {
var price = matches[1];
}
else {
// Not found
}
Note this will match any sequence of characters after the word Price:. If there is whitespace after the word price, it will break. If there is no space after $20, it will break. You need to make the rules more complex depending on your input source.
Split the string by : and then with space.
string.split(":")[1].split(" ")[0]
Various solutions without regular expressions :
var s = 'Price:$20 is very cheap';
var s1 = s.slice(6, s.indexOf(' '));
var s2 = s.slice(s.indexOf(':') + 1, s.indexOf(' '));
var s3 = s.slice(s.indexOf('$'), s.indexOf(' '));
// s1 === s2 === s3 === "$20"
var str = 'Price:$20 is very cheap';
var price = str.split(' ')[0].split(':')[1]; // $20
var matches = /Price:(\$\d+)/.exec(string)
matches[1];//"$20"
You can use string.split(":")[1].split(" ")[0]
or else you can use combination of str.substring(); & str.indexOf();.Fiddle example:
Using Regular Expression is a better way, as string methods cannot return correct answers on all cases.
