Sending variable on mouseover

zingzing45 · 09-20-2012, 12:19 AM

Hi, I am trying to send a variable on mouseover but it does not seem to work - I took this to the PHP forum, since PHP was involved, but a guy there said that it was not a PHP problem.

So can anyone spot a possible error in this code?

Code:

function addAward()

{

$(document).ready(function()

{

$.ajax(
		
		{
		
		type: "POST",
		
		url: "achievements.php",
		
		data: { HomeCoinLocator: "Yes" }

		});

		});

var div = document.getElementById("newachievementdiv");

var span = div.getElementsByTagName("span")[1]; 

span.innerHTML = "' . $endtext . '";

$(div).fadeIn("4000");

setInterval( function() { $("#newachievementdiv").fadeOut("4000"); }, 4000);
		
}

BTW, the important stuff is in bold.

Thanks.

Three things ...

1) And this is the main problem: You are trying to access the DIV with ID "newachievementdiv" outside of the $(document).ready() callback. So this DIV might not be ready yet
2) There is no event handler for mouseover ... so how should your program know that it should send something on mouseover?
3) You are already using jQuery, so you should not use getElementxxxxxxxxxx methods but rather the respective jQuery methods like $('#newachievementdiv span').eq(1)

Thanks for the tips - the first one I'll look into, but the second one is something that you didn't see.

The function is called on a mouseover inside the HTML tag, but I didn't show that part. Finally, I might look over the third tip you gave me.

Thanks a lot, that might help me out a lot

Help -

<script>

function addAward()

{

$(document).ready(function()

{

$.ajax(

{

type: "POST",

url: "achievements.php",

data: { HomeCoinLocator: "Yes" }

});

var div = $("#newachievementdiv span").eq(1)

var span = $("span").get(4);

span.innerHTML = "' . $endtext . '";

$(div).fadeIn("4000");

setInterval( function() { $("#newachievementdiv").fadeOut("4000"); }, 4000);

});

}

</script>

Why doesn't this work?

Code:

function addAward()

{

$(document).ready(function()

document.ready cannot (or at least, should not!) occur within a function. But you never call the function (unless you call it from some code that you haven't shown us) so the code is never executed.

[Personally, I wouldn't use div and span as variable names - it can only lead to confusion, and possible conflict.]

This

Code:

span.innerHTML = "' . $endtext . '";

seems to be wrong. It should be

Code:

span.innerHTML = "'" . $endtext . "'";    // or perhaps..
span.innerHTML = "$endtext";

depending on where/how it is positioned within your PHP code.

Even though I followed all of your advice, this code below doesn't work!

<div id="secretcoin" onmouseover="addAward();">

</div>

<div id="newachievementdiv" align="center" class="awardBox"
style="display: none; margin: 0px auto; position: fixed; left: 250px;">
Congratulations! You have <span class="highlite-blue">found the secret coin</span>!
<br/>
<span></span>
</div>
<script>

$(document).ready(function()

{

function addAward()

{

$.ajax(

{

type: "POST",

url: "achievements.php",

data: { HomeCoinLocator: "Yes" }

});

var div = $("#newachievementdiv span").eq(1)

var span = $("span").get(4);

span.innerHTML = "' . $endtext . '";

$(div).fadeIn("4000");

setInterval( function() { $("#newachievementdiv").fadeOut("4000"); }, 4000);

}

});

</script>

BTW, that div junk at the beginning is where the function gets called.

So does this have any visible errors in it? Does anyone know of any weird problems that I might be experiencing?

devnull69 · 09-26-2012, 09:43 PM

I don't get it ... is this a mix of PHP and Javascript? Is $endtext the only PHP code here? If this part is PHP, please show us the resulting Javascript code from your browser.
