Javascript - Find Comma Exists In String

Question

I need to find if a comma exists in a javascript string so I know whether to do str.split(',') on it or not.

Is this the correct way: var myVar = str.search(','); ?

If the value of myVar is greater than 0 (zero) then there is a comma in the string?

I'm just not sure if I've got the parameter right in search()

Thanks!

Answer 1

Try using indexOf function:

if (string.indexOf(',') > -1) { string.split(',') } 

Answer 2

Use new functions natively coming from ES6:

const text = "Hello, my friend!"; const areThereAnyCommas = text.includes(','); 

Answer 3

.search() is used for regular expressions, making it a bit overkill for this situation.

Instead, you can simply use indexOf():

if (str.indexOf(',') != -1) {
    var segments = str.split(',');
}

.indexOf() returns the position of the first occurrence of the specified string, or -1 if the string is not found.

Answer 4

var strs;
if( str.indexOf(',') != -1 ){
    strs = str.split(',');
}
