Question

HTML:

<p class="greeting">
  hello, my name is kevin. what's yours?
</p>

jQuery:

$("p.greeting").filter(function (){
  return $this.text() === "my name is";
}).css("background", "green");

I’m trying to isolate the words “my name is” in the <p class="greeting"> tag. Can anyone help me with the jQuery as it doesn’t seem to work. Thanks.

Here you go:

CSS:

.highlight { background-color: yellow; }

JavaScript:

var text = 'My namE iS';

$( 'p.greeting' ).html( function ( i, html ) {
    var regexp, replacement;

    regexp = RegExp( '(' + text + ')', 'gi' );
    replacement = '<span class="highlight">$1</span>';

    return html.replace( regexp, replacement );
});
