Hello!

The function changes the background-color of the input field.</p> First name: <input type="text" id="fname" onfocus="setStyle(this.id)"><br> Last name: <input type="text" id="lname" onfocus="setStyle(this.id)"> </body> </html> Many thanks!!! |

Please try to post new threads in relevant sub forums. This one seems to be about client side javascript, so I moved the thread here.

QUOTE(pinklemon @ Jul 5 2014, 08:12 PM)  can somoene tell me what EXACTLY means "this" in next example: CODE <input type="text" id="fname" onfocus="setStyle(this.id)"> In that example it means the HTML element. In other contexts it can mean other things. See http://quirksmode.org/js/this.html for details. |
