jQuery indexOf to ignore Case

Question

I am trying to find if an image has in its source name "noPic" which can be in upper or lower case.

var noPic = largeSrc.indexOf("nopic");

should i write

var noPic = largeSrc.toLowerCase().indexOf("nopic");

It doesn't work

Answer 1

No, there is no case-insensitive way to call that function. Perhaps the reason your second example doesn't work is because you are missing a call to the text() function.

Try this:

var noPic = largeSrc.text().toLowerCase().indexOf("nopic");

Answer 2

You can use regex with a case-insensitive modifier - admittedly not necessarily as fast as indexOf.

var noPic = largeSrc.search(/nopic/i);
