javascript string method

Question

hi i want to a one line of code (without using loop) in javascript to find the if there is semicolon in a string... please help if any one knows

Answer 1

myStringVal.indexOf(";") !== -1;

_{For more information, check out the documentation for String.prototype.indexOf() .}

• T.J. Crowder: +1 (although I always advocate >= 0 rather than != -1 out of paranoia; but the spec does specifically say -1 for not found, so...) But please refer people to the specification. w3schools is incomplete at best.

Answer 2

if (stringvalue.indexOf(";") >= 0) {
 alert("String value contains semi colon");
}
