Q:

How to check an entire string if it contains a specific word using jQuery?

I need help on checking a certain word if it contains in a string that is being assigned into my input textbox.
For example below, If there's a string value assigned to this textbox
<input type="text" id="StartLocation" name="StartLocation" value="1 AAC, MT SECTION, RAF SCAMPTON, LINCOLN, LN1 2ST, UNITED KINGDOM" >

I want to check if it contains the word "UNITED KINGDOM" and if does not, it should return false.
I tried something like this below but it keeps returning true because the alert message is always 'It contains United Kingdom' even though I already
change the value. 
if ($("input#StartLocation:contains('UNITED KINGDOM')")) {
  alert('It contains United Kingdom');
} else {
  alert('It does not contains United Kingdom');
}

How do I fix this? Thanks...

A:

try this
if ($("#StartLocation").val().indexOf('UNITED KINGDOM') >= 0) {

}
