TalkPHP - View Single Post - onfocus and onblur events -- I'm confused, of course...

Dave · 10-18-2009, 09:11 PM

This is the first time I have dealt with onfocus and onblur. I researched it, so I know a little more that I did.

In the following example snippet, however, I don't get the \" part. I know that the \ is used to escape the next character. However, I'm still confused. So, my questions are:

1. Is the coding in the onfocus example a Javascript applet? (...don't know javascript..)
2. What is the \" doing?

Thanks,
Dave

PS. I did not compose the example code below. (Unlike my code, it works.)

PHP Code:


			
<?php



if (!$username&&!$userid)

  echo "<span class='bigheader'>

              <img src='login.png'>

        </span>

        <p>" ;

else

     echo "<p><a href='logout.php'>Log out</a><p>

        <form action='user.php'

              method='GET'

              style='display:inline;'>

          <input type='text'

                 size='15'

                 value='Jump to member'

                 name='user'

--->             onFocus=\"if (this.value == 'Jump to member')

                           { this.value=''; }\"

--->             onblur =\"if (this.value == '')

                           { this.value='Jump to member'; }\">

                 <br>

          <input type='submit'

                 value='GO'><p>

        </form>

       " ;

?>
