DOM - Show BODY In The Alert Box
Feb 11, 2009
I'm experiencing some strange issues using the DOM with JS. Let's say this is my HTML source:
<html>
<head>
<title></title>
<script type="text/javascript" src="exercise1.js"></script>
[Code]....
And here is the one line of code in my external JS file: window.alert document.documentElement.lastChild.tagName); This should show BODY in the alert box, shouldn't it? It doesn't, it shows HEAD (in FF 3, IE 7 & Safari 3) and I really have NO (!) idea why it is doing that. Let me show you another example of why it's driving me insane.. window.alert(document.documentElement.lastChild.firstChild.tagName); Should show P, no? It doesn't. FF 3: undefined, IE 7: TITLE, Safari 3: undefined. Again, the question is: Why?!

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
I cannot even get a window alert to pop up. All I want to do is call the function in the body.

Right I have a process page in php which is fairly long and complex with many options. If a certain option case is met as this ie: we've hit the Note Saved case.
// save notes against company
if ($_POST['a']=="Save Note") {
if (addnote($_POST['notetitle'],$_POST['notebody'])) {
$err = "<p id="returnresults"><font color="red"><strong>Note Saved</strong></font></p>";
} else {
$err = "<p id="returnresults"><font color="red"><strong>Failed to save note.</strong></font></p>";
}
}
I want to then wait until the page load is complete and then do the following.
document.getElementById('addevent').style.display='block';
The reason I need to wait for page complete is that the div that needs to be displayed it one of the last parts of the page rendered so triggering the above too soon leads to the div not actually being available to be shown. Now my current fail attempt at doing it was this echo "<script type="text/javascript">if (confirm('You have not yet added a call back event do you wish to do so now?')) { document.getElementById('addevent').style.display='block'; } However it doesn't display the hidden div

I would like to learn jquery but have already stumbled upon a little problem.
My whole website is programmed in PHP. On every page I include my header.php containing the header, login bar etc. I am now trying to show/hide a set of divs in my HTML BODY.
Now I understand that I need to put my jquery code in my HTML HEAD tags, however, I don't want to put it in my header.php because then the jquery will be included in all my pages.

When you click on the "Printer Friendly Order Summary" button, an alert for the req'd fields popups up THREE times and I don't know why.... it's also popping up EVEN when all req'd fields have been filled out, and then it proceeds to the next page as it should. This used to work, I have no idea what happened! http:[url]....

i have a form. i'm going to store the field into mysql. there are 2 conditions : one or all fields empty OR none is empty. when there's no empty field, the data will be stored. but, when there's empty field, no data will be stored and there will come up the alert "please fill all the fields!" here's the form :
<form method=POST enctype='multipart/form-data' onclick='show_alert()' action=insert.php>
<table>
<tr><td>Data 1</td><td><input type=text name='data1'> </td></tr>
<tr><td>Data 2</td><td><input type=text name='data2'> </td></tr>
<tr><td>Data 3</td><td><input type=text name='data3'> </td></tr>
<tr><td colspan='2'><input type=submit value='Save'><input type=button value=Cancel onclick=self.history.back()></td></tr>
</table></form>";
[Code]...
i don't know how to show the alert with javasript.

I was told to use some Javascript to achieve collapsing menus. This is my current try, but it doesn't seem to be working. The end result should be like the menus on this site: [URL]
This is my code so far:
<HTML><HEAD>
<title>Test</title>
</HEAD><BODY>
<script type="text/javascript">
var hide = 0;
function Show(){
alert("Test");
if ( hide == 0 ){
document.write("<a href=\"county.htm\">County</a>");
hide = 1;
} else {
document.write("");
hide = 0;
}}
</script>
<input type="button" onclick="Show()" value="Services" />
</BODY></HTML>
For some reason, Show isn't being called. The alert doesn't even show up. Though I'm under the impression the script should go above the first time it's used in the document.

I had some code that kept repeating itself over and over again, with the only variance being some named elements changing. All the named elements ended in a sequential number, so I figured I'd just put one of the repeating blocks into a "for" loop and then make that sequential number at the end of the named elements into the variable in the loop. Again, the code worked fine when copied/pasted over and over, but now it doesn't do anything. Here's one of the code snippets outside of the loop (which worked):
Code:
$(document).ready(function () {
$("#SelectDiv1").change(function() {
if ($("#DD1").val() != "0") {
$('#SelectDiv2').hide();
$('#SelectDiv3').hide();
$('#SelectDiv4').hide();
$('#SelectDiv2').show();
$.ajax({ .....
You can see there's an "alert" as the first part of the loop. That "alert" never shows up. However, if you comment out everything in the loop after the "alert", then the "alert" works. So something else in that loop is causing the whole thing to not work. I find it odd that the first "alert" wouldn't work, though, since it should be the first thing that happens before any of the other code is executed in the loop, right???

I'd like to have an alert of some type, either standard alert or a hidden div, show up when a user selects an option in a select element.
For instance, if a select element has 5 options in it and the user chooses the first one, they would get an alert that says "You have chosen the first option". I'm confident this is something that can be done with a few lines of code, but I'm not sure where to begin.
Here's the logic - I'm just not sure how to write the syntax...
If ("#select option") changes and ("#select option:eq(0):selected"), fade in the div ("alert").

I'm trying to make my body content scroll at the same time as an iframe located within the body. This has to do with the age old problem of mouse focus on iframes. When my mouse reaches the iframe and it takes over focus, I would like the body to keep scrolling until the iframe is right at the top of the screen. After that I want to relinquish focus to the iframe. I don't mind if the iframe starts scrolling as soon as the mouse reaches it, so long as the main body keeps scrolling for a while.

It's possible to style document.body not to start at 0,0 for example: body {width: 1000px; margin-left: auto; margin-right: auto;} This means that X/Y of the body is not 0,0 but how can I find out what the position is using javascript? document.body.offsetLeft; is 0 and offsetParent is null yet if I position something absolutely at 0,0 it goes to 0,0 of the window, not the body!

I need to execute a JavaScript function "onload". The only problem is I
don not have access to the <body> tag as it is a part of the standard
page-header include (a separate file). How could I have certain pages
execute my function() onLoad?
The function basically just sets the original values of fields so that I
can determine if a field has been changed or not, which aleviates unnec.
sql update on the backend..
