2 ajax requests onMouseOver and onClick in one span segment.

technotool · November 2, 2008

First, thanks for taking the time to read this problem.

I have a script which uses some text in <span> tags. When the user onMouseOver 's the text an ajax function( toolTip() ) is called and --> some text in a div displays. When the same text is onClick 'ed another ajax function( recallText() ) is called and some text is inserted into a textarea.

individually, the ajax behaviors work perfectly but when I combine the behaviors only the onMouseOver function works. The onClick function doesn't work. I keep both functions on the same js source file.

Here is the span segment.

Do I need to do something special when there are 2 requests in the same tag?

echo "<span id=\"$field_id\" onMouseOver=\"toolTip(this.id);\" onMouseOut=\"clearPopup();\" 

onClick=\"recallText(this.id);\">".$field_title."</span><br>";

Here is the entire code files in one text file.


//////////////////////////// get_pText.php file ////////////////////////

<?php

$q=$_GET["q"];



$con = mysql_connect('localhost', 'root', 'password');

if (!$con)

{

die('Could not connect: ' . mysql_error());

}



mysql_select_db("osemr", $con);



$sql="SELECT * FROM textfields WHERE fld_id = '".$q."'";



$result = mysql_query($sql);



while($row = mysql_fetch_array($result))

{



echo $row['fld_text'];



}



mysql_close($con);

?>

Didn't check it, but I noticed clearPopup has one argument (str), and in your span , you call it without any arguments...

could that be it? I know javascript is picky. Also, use firefox's error console to debug javascript!

function recallText() didn't have enough closing braces "}" and so it was executing the function downstream. basically needed to close off each of the ajax functions with closing "}". It is working great now. thanks
