Sample Use of JavaScript OnFocus and OnBlur Event

You can see this example on many sites today such as yahoo mail.

When you click on the search box, the word “Search” will go.

When you click on another part of the webpage, the word “Search” comes back in it.

HOW TOs.

Step 1: Create your index.html file and put the following codes:

<html>
     <head>
          <title>Sample Use of JavaScript OnFocus and OnBlur Event</title>
     </head>
<body>
     <input type="text" value="Type keywords here..." size="40"
       OnFocus="if(this.value=='Type keywords here...') this.value='';"
       OnBlur="if(this.value=='') this.value = 'Type keywords here...';" />
</body>
</html>

TIPs

This thing is used often in search boxes. You will save webpage space ‘coz you won’t have to put the label “Search” before the search box
