Here's the function:

And here is where i call it:

Why this doesn't work? I've tried onkeydown= "KeyCheck()" too.

Simple Echo OnClick Function Not Working

Jul 6, 2010

I am trying to do a simple echo onclick, but despite what I try to do, it shows no errors, but won't work. I've tried things like:
echo "<div onclick="alert('test');">t</div>";
echo '<div onclick="alert('test');">t</div>';
But just can't seem to get it to work right. I'm trying to do this on a script that is being eval on the ajax request. Thus I'm having problems placing the ',", marks.

When Event Run Function Not Working

Nov 1, 2011

In the file script.js I got 2 functions:
Code:
function tooltip(){
var m=document.getElementsByTagName("A");
var k=[];
var mover = document.createAttribute("onMouseOver");
mover.nodeValue = "showtooltip()";
for (var i = 0; i<m.length; i++) {
var mover = document.createAttribute("onMouseOver");
mover.nodeValue = "showtooltip()";
m[i].setAttributeNode(mover)
}}
This one is working. It's putting into <a href="#" title="some title" /> an attribute: onMouseOver with value: showtooltip()

And that's my 2nd function.
Code:
function showtooltip() {
document.write(this.getAttribute("title"));
}

When event is run the function isn't working. But when my html looks like this:
Code:
<a href="#" title="some title" onMouseOver="document.write(this.getAttribute("title"))">link</a>
Everything is fine. And javascript console doesn't show any errors.

My 2nd problem is, that onMouseOver doesn't work in chrome (I got dev version). Even function like this:
Code:
showtooltip() {
document.write("......");
}

Function In OnLoad Event Not Working

Sep 14, 2010

I've been developing an application that uses a combination of Javascript and PHP. It's a sizeable form that includes the option for the user, on certain form objects, to add additional text boxes for multiple answers. I created a Javascript function that uses the insertRow() method. The user can click on a link which adds a row with a text box for an additional response. My function works great and, after some work around I got the values to post correctly, but where I'm running into trouble is re-populating those additional fields if I have to bring the user back to edit input that was not put in correctly.

My solution was to have create a PHP varible which is a javascript function call, e.g.:
$var = "js_function('varName1','varName2', 'varName3', 1 , '" . $post_val . "')";
Using the posted variables that apply and then echoing that into the onload event handler in the body tag. This calls the same function that was originally used to add the row to have it add the row again and populate it with the already submitted data. It all looks great, like it should work, but it doesn't and I'm wondering if there is something about the onload event handler which I don't know about. It was my understanding that the event handler executes when the page is fully loaded. If that is the case, my solution should work.

I don't know if there's some error I'm not seeing or if I'm trying to make the onload event handler do something it's not supposed to. I used a similar solution on another application and it works there. To give a better understanding, here is the function:
function appendIaRow(tblId, valID, oName, Nbr, populate1, populate2) {
var tbl = document.getElementById(tblId);
var newRow = tbl.insertRow(tbl.rows.length);
var numi = document.getElementById(valID);
var num = (document.getElementById(valID).value -1)+ 2;
numi.value = num;
var rowID = 'Row'+num;
newRow.setAttribute('id',rowID);
var newCell = newRow.insertCell(0);
newCell.innerHTML = "<input type=\"text\" name=\""+oName+"Name["+num+"]\" value=\""+populate1+"\" size=\"20\" maxlength=\"150\"/> <a href=\"Javascript:;\" onclick=\"deleteLastRow('"+tblId+"','"+rowID+"');\" style=\"text-decoration:none\">X</a><br /><br />";
var newCell2 = newRow.insertCell(1);
if (Nbr == 1){
newCell2.innerHTML = "";
}else{
newCell2.innerHTML = "# <input type=\"text\" name=\""+oName+"Number["+num+"]\" value=\""+populate2+"\" size=\"17\" maxlength=\"17\"/><br /><br />";
}}

Here is the coding for the event handler('initialize()' is a different function altogether - that works):
<body onload="initialize(),<?php echo $init ?>;">
And here is what it looks like from the source code when the page is displaying in a browser:
<body onload="initialize(),appendIaRow('AdmTbl','AdmValue','Administrator', 1, 'Joan'),;">

Very Simple Rollover Image, Not Working?

Feb 15, 2010

This code works:

Code:
<html>
<script language="Javascript">
if (document.images) { [url].....

What happens: You see both image1 and image3, but when you mouse over either of them, nothing happens...So I'm trying to have "multiple images" rollover...

Edit: So by adding in the red, that's when all rollovers cease to function.

In firebug I can see the match in the if statement is fine, the onClick function is attached to the element and I can watch it stay there through to the end of debug session. But when I click on the element.

JQuery :: Simple Ajax Post Method Not Working?

Sep 11, 2010

I'm pretty new to jQuery so try and go easy. Trying to do a simple AJAX POST using the jQuery post method and it doesn't seem to be working.

Heres my code:
$.post("sub-account-ajax.php", { email_address: "test@test.com" },
function(data){
alert("Data Loaded: " + data);
});

Heres the code for sub-account-ajax.php:
<?php
if (isset($_POST['email_address'])){
echo 'youre set';
}else{
echo 'nothing set';
}?>

When this code is executed I do not get any alerts or any error messages whatsoever. I've been pretty good with figuring things out so far with jQuery, but this is the first I'm stumped with.
