[SOLVED] Javascript not being called from HTML

stockton · April 13, 2007

I have a web page that includes javascript as follows:-

I have attempted and tested this when coded between the <head> and </head>

as well as after the </html> tags and cannot get it to work.

The html that should access this are :-

and those called functions are all within the AdjustmentFunctions.js file as follows:-

function AdjustmentDone()

{

window.location="Administration.php";

}

function ClearAdjustmentForm()

{

document.getElementById("CardNumber").value = "";

document.getElementById("MemberName").innerHTML = "";

document.getElementById("Amount").value = "";

document.getElementById("Reason").value = "";

document.getElementById("CardNumber").focus();

}

function CheckAmount()

{

if (!document.getElementById("Amount").innerHTML)

{

alert ("An value must entered");

document.getElementById("Amount").focus();

return false;

}

else alert(document.getElementById("Amount").innerHTML);

}

function CheckReason()

{

if (!document.getElementById("Reason").value = "")

{

alert ("A reason is required and must be entered");

document.getElementById("Reason").focus();

return false;

}

if ((document.getElementById("Amount").innerHTML) &&

(document.getElementById("Reason").value))

{

document.getElementById("Issue").disabled=false;

}

function submit_click()

{

var bError = false;

var strErrorMsg = "";

document.getElementById("Issue").disabled=false;

Adjustments.submit();

}

Other pages using javascript work fine. Just this one fails.

Please tell me how I got this one wrong?

Well your JavaScript looks clean and since I can't see your HTML file I will just suggest a couple of things:

Ensure that the code that links to the script is inside your <head> element.

<html>
<head>
	...
	<script language="JavaScript" type="text/javascript" src="js/AdjustmentFunctions.js"></script>
	...
</head>
...
</html>

The code that calls the script is using relative linking which means that the .js file needs to be in a folder called "js" that is in the current working directory. It that isn't the case you may need to change your pathing by starting from the webroot.

The page looks like:-

<html>

<title>Adjustments</title>

</head>

<?php

require_once('includes/configuration.php'); // database connect script & the rest.

require_once('includes/logo.inc');

// We 1st check if user has logged on and has authority to add, delete or amend Earn Rates.

if ((!$_SESSION['UID']) && (!$_SESSION['Usrname'])) // Not logged in

{

$Message = sprintf("%s %d <br> Logon to be able to access this task!", __FILE__, __LINE__);

trigger_error($Message, E_USER_ERROR);

exit;

}

if ($_SESSION['UserRights'] <

{

$Message = sprintf("%s %d <br>User %s with access level %d does not have authority for this task!",

__FILE__, __LINE__, $_SESSION['Usrname'], $_SESSION['UserRights']);

trigger_error($Message, E_USER_ERROR);

exit;

}

?>

<h2>Adjustments</h2>

<tr>

<td>Event:<br></td>

<?php

DBConnect(); // Connect to Events database

// Get todays date.

$Datum = date("Y-m-d H:i:s"); /* 2006-03-17 23:22:32 */

$SQL = "SELECT EventID, EventName, LastDrawDate FROM Event WHERE '$Datum'>=EndDate AND '$Datum'<=LastDrawDate";

$rs = mssql_query($SQL, $link);

echo "<br /><center><td><select name='Event'>";

$Count = 0; while ($row = mssql_fetch_array($rs))

{

$EventID = $row['EventID'];

$Message = sprintf("%s", $row['EventName']);

$LastDrawDate = $row['LastDrawDate'];

echo "<option value=$EventID>$Message</option>";

++$Count;

}

if ($Count == 0)

{

$Message = sprintf("%s %d <br>No events currently applicable!", __FILE__, __LINE__);

trigger_error($Message, E_USER_ERROR);

exit;

}

$SQL = "Select EarnTypeID, TableType, EarnType from EarnType";

$rs = mssql_query($SQL, $link);

echo '<tr><td>Earn Type :<br /></td>';

echo '<td><select name="Earn Type">';

$Count = 0; while ($row = mssql_fetch_array($rs))

{

$EarnTypeID = $row['EarnTypeID'];

$EarnType = sprintf("%s", $row['TableType']);

echo '<option value='.$EarnTypeID.'>'.$EarnType.'</option>';

++$Count;

}

if ($Count == 0)

{

$Message = sprintf("%s %d <br>No Earn Types defined!", __FILE__, __LINE__);

trigger_error($Message, E_USER_ERROR);

exit;

}

DBDisConnect();

?>

</td></tr>

<font size=+1>Member No:<br />

Member Name :<br />

Amount :<br />

Reason :<br /></font>

</td><td>

<input type=text name="CardNumber" id="CardNumber" onBlur="sendRequest('<?php echo $GetName.",".$EventID ?>',this.value)">

<div style="position:relative;" id="MemberName";><b>Member name.</b></div>

</td></tr>

</table>

</form>

<br />

</center>

<?php

require_once('includes/tail.inc');

?>

</body>

</html>

document.getElementById("Issue").disabled=true;

document.getElementById("CardNumber").focus();

</script>

and the AdjustmentFunctions.js is in the correct folder and the Ajax scripts work fine.

Generally when your JS stops working it can also be because there is a JS error somewhere. If you use firefox (and have the Web Developer add-on installed) you can see the Browser's Error Console and if your page in firefox it will show you where your JS is breaking, if that is the case.
