Poll with image input type not working

Copy linkTweet thisAlerts:
Mar 24.2013

Hello

I am having a problem making a php+ajax poll work. The code can be found here: [URL=”http://www.w3schools.com/php/php_ajax_poll.asp”]http://www.w3schools.com/php/php_ajax_poll.asp[/URL]

Now instead of

[CODE]<input type=”radio” name=”vote” value=”0″ onclick=”getVote(this.value)”>[/CODE]

I’ve changed it to

[CODE]<input type=”image” src=”image.png” name=”vote” value=”0″ onclick=”getVote(this.value)”>[/CODE]

in hoping that when I click on the image, the same result would be produced like when its a radio button.

But its not working. By that I mean when I click the image, nothing happens, and the values in poll_result.txt doesn’t change either. As for the URL I get [url]http://localhost:8080/[/url][B]?vote.x=181&vote.y=90&vote=0[/B]

Any help would be much appreciated.

Cheers

@rtretheweyMar 24.2013 — <input type="image"> is treated the same as <input type="submit">. So when you click on it, the JavaScript is being executed, but the <form> is "submitted" immediately thereafter. That means the browser will (essentially) reload the page and it looks like no changes have occurred. Try using a plain <img> tag instead. You won't be able to use 'getVote(this.value)', since <img> tags don't have a 'value' attribute. But you should be able to find a workaround easily enough.

Thank you it solved my problem. I didn't even think about using the img tag ?
