Question

JQUERY - IF the element's current value ends with !!!, trigger an Alert

Answer 1

+1 A:

It looks like there is a \n after the !!!. Use /m flag for making the regex multiline.

if (/!!!$/m.test(value)) {
    console.log("it works");
}

Check this:

var s = "When the user tl, sem.The 3 !!!";

if (/!!!$/m.test(s)) 
    console.log("multiline matches");   //prints

if (/!!!$/.test(s)) 
    console.log("single line matches"); //prints

s += "\n";

if (/!!!$/m.test(s)) 
    console.log("multiline matches");   //prints

if (/!!!$/.test(s)) 
    console.log("single line matches"); //doesn't print

Answer 3

A:

$this doesnt refer to self. $(this) refers to self. so it should be like:

var value = $(this).text();

full eg.:

<body>
    <p>hello!!!</p>
    <p>done</p>
</body>
<script>
    $(document).ready( function()
    {
        $("p").click( function()
        {
            var value = $(this).text();
            if (/!!!$/.test(value)) { msg = 'done';}else{ msg = 'not done';}
            alert(msg);
        });
    });
</script>
