JavaScript - Drop Dopwn Box When User Leaves The Page

our requirement is client wants to know howmany users leaving the main page without entering
data in the application page.at that time we need to show the css popup overlay.

in the following scenarios overlay should pop up.

1)when user leaves the page.(e.g. type other address in the address bar).bascially user shy away from the browser.
2)clicks browser close button.


we will show one css popup overlay(not browser popup) and in the back ground main application will be greyed out.this overlay consists of some text fields and some buttons will be there and parallely in the back ground we will execute AJAX call.

can we accomplish this requirement??is yes how?will it work in all browsers?
my concern is how to prevent the browser from closing(e.g.when user chooses browser X button) when css overlay comes up.

I'm working in iWeb (I had to say that first). I need to create (using JAVASCRIPT) a text box with a button. When the button is clicked, the contents of the box are added to the URL (the url is in the code, probably a variable, for this example it is mydomain.wordpress.com/) and the url produced loads. For example, if the text "Hello" was printed in the text box once the button is clicked the page mydomain.wordpress.com/Hello is loaded.

Hi there guys! My group is working on a basic document management system that includes four users. staff member, department director, division chief and clerk. The programming language that we used is PHP.

when staff member logs-in on his homepage and uploads a file he must choose reviewer from a dropdown menu that consists of dep. director and div. chief.

When he clicks the upload button the homepage of who he chose as reviewer should receive a prompt/alert box upon log-in saying "you have a document to review".

For example:
if he chose division chief as the reviewer when the person logs-in on his homepage a prompt/alert should display that he has something to review.

The code for uploading file is already up and working. We are looking for advice on how to integrate javascript in this system. Especially in the prompt part. thanks for your ideas.

How could I open a page/popup after closing one?
The objective is to log the user out if they haven't Logged out or clicked Logout.

I am sure there is a simple way to do this. None of my ideas work.

The only answer I could come with (after testing the whole day...)
IE(any version), Firefox, and other browsers don't support this idea, due to the fact that the user clicked close and you can't impose things on them.

I want to use javasript to create a new html page named from a text field in a form. Then I want to use javasript to copy all of the form fields to the new html page that was created using javascripting. I am creating a user are using a Javascript password login. With most of them the page is the user name or password. So this is why I am looking to do this. I use web 1000 a free host and they will only let me use javascripting. Any info or help would be great thank you

Hi,

Please i am not getting clear understanding of a javascript code to redirect user to a different web page based on the day of the week.

Please i have search for many script and not getting clear understanding from their code.I have also try several code myself but nothing good has come from it.

Please can someone help me and write a descriptive code for me to understand better.I really plead you and your to help me...but i belief the Lord God will bless you for your time helping me.

On various video sites you can click cinema mode and the page goes dark, whilst you watch the video.

On my page I have a box which appears, where the user enters their name and email address. But I would like the box to remain active and in view. While the rest of the page goes darker and unusable, Like on the video player websites


How do I do this?

I have a small form that I'm working on for a client. They want a form that their potential leads can fill out and then hit 'calculate rate'.

Once this is done, the results should display on another page with a short summary of what their quote will be as well as some of the other information they filled out. It should also send an email to my client displaying the information that their lead just filled out. My only problem is I am not sure how to go about the calculation part. I know I would have to do an onSubmit, but how would I hide that calculation and then receive that number on another page. Here is the javascript for that form:

    var divobj = document.getElementById('totalPrice');
    divobj.style.display='none';
}

If you look at the bottom you can see where the Function that Calculates everything is. Right now it calculates onClick. I just want it to calculate after the user has filled out the form completely and display that calculation on another page along with the rest of the information they inputted.

I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text.

Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box.

The clickable link could be a button, image or text (no preference).

They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately.

Question:

What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7).

I offer $10 via paypal for well commented method/script.

I have a page with multiple drop down menus for selecting a State then City, then Zip. The State and City both work fine but I can't seem to make the Zip function properly.

Page with drop downs:
Code:

var xmlhttp;
function showCity(state)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Browser does not support HTTP Request");
  return;
  }
var url="get_cities.php";
url=url+"?q="+state;
url=url+"&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
var s=state;
function stateChanged()
{
if (xmlhttp.readyState==4)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}

function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}


var xmlhttp;

function showZip(city)
{
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null)
  {
  alert ("Browser does not support HTTP Request");
  return;
  }
var url="get_zips.php";
url=url+"?z="+city;
url=url+"&q="+s;
url=url+"&sid="+Math.random();
xmlhttp.onreadystatechange=stateChanged1;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}

function stateChanged1()
{
if (xmlhttp.readyState==4)
{
document.getElementById("txtZip").innerHTML=xmlhttp.responseText;
}
}

function GetXmlHttpObject()
{
if (window.XMLHttpRequest)
  {
  // code for IE7+, Firefox, Chrome, Opera, Safari
  return new XMLHttpRequest();
  }
if (window.ActiveXObject)
  {
  // code for IE6, IE5
  return new ActiveXObject("Microsoft.XMLHTTP");
  }
return null;
}

</select>

I have my page set to only show the drop down's when there is a value to select. The Zip drop down shows up at the correct time but is empty.

I've tried searching the forum but since I'm still learning js I wasn't able to make use of any on the other multiple drop down examples I came accross.

Thanks for any advice you can offer.

Hi,

I'm looking for help, please. I am trying to setup a donation form for a friend, where someone can click radio buttons for set donation amounts, or click the "other" radio buttons and enter a different amount. The donation amount is then passed over to a secure credit card entry page, hosted by a 3rd party merchant.

I can set up all the pre-defined radio buttons to correctly pass on the donation amount to the credit card page, but I cannot figure out how to work the "other" radio button amount.

Any help would be very much appreciated!

Thanks!

how can set focus on Drop down after page is reset .

when i press down key first time its working fine and select value but when i press again down key its focus out from drop down

when i hard code means i give the control name its working fine but when i checking the type document.getElementById(document.activeElement.id).type == "select-one"

its getting focus out after second time pressing down key
sample code



if (document.getElementById('control name'!=null) {
document.getElementById('control name).focus();
if (document.getElementById(''control name)[document.getElementById('cntrlname').selectedIndex+1] !== null) {

document.getElementById('cntrlname').selectedIndex=document.getElementById('cntrl namer').selectedIndex+1;

document.getElementById('ctr name').onchange();
document.getElementById("ctlr name").selectedIndex = document.getElementById("ctr name").selectedIndex;
document.getElementById('cntrl').focus();


}
return false;
}


This code is working fine but this is spcefic to the control i want all drop down control in my app are set by pressing

I have been searching for a long time but have been unsuccessful on how to develop a drop down menu but have the menu items show in a list above the main nav. Not below. I really like the way this functions:

http://www.sohtanaka.com/web-design/examples/toggle/

But I would like the item in the list to appear above the main nav so it animates up not down. Can anyone help me on how to alter this js code to perform this task?

Here is the jQuery file link:

http://code.jquery.com/jquery-latest.js

I tried going through this js file but it very complex. Can anyone tell me what I need to change to have the animation roll up instead of down? Any help would be most appreciated.

Hello everyone!

So, what it does: You can successfully drag something anywhere, but when you click it again, it resets to its original position (I don't know why), and when you try to drag it again, as soon as your cursor touches the object it disappears (I don't know why). I'm hoping someone can tell me why it is happening and how to fix it!

Code:

// JavaScript Document

var posX;
var posY;
var element;

function drag(event) {
	element = document.getElementById("square");
	posX = event.clientX;
	posY = event.clientY;
	element.addEventListener("mousemove", move, false);
}

function move(event) {
	
	if (typeof(document.getElementById("square").mouseup) == "undefined")
		element.addEventListener("mouseup", drop, false);
	//Prevents redundantly adding the same event handler repeatedly
	
	element.style.left = event.clientX - posX + "px";
	element.style.top = event.clientY - posY + "px";
}

function drop() {
	element.removeEventListener("mousemove", move, false);
	element.removeEventListener("mouseup", drop, false);
}

the html is a simple (position is set to relative):

<p id="square" onmousedown="drag(event)">meep</p>

Lastly, and most importantly, thank you all for your time =]

EDIT: This is the first time I've written javascript code and would like to learn the basics, which is why I am not using a library.

Hello there, CodingForums.com!

I'm a newbie to Javascript, HTML, XHTML, CSS-- and oh god, everything, so please bear with me! I have come to understand that to get any better, I'll need support. I hope you guys (and gals) can assist!

Here is my issue: I'm currently trying to develop a first-draft calculator that will allow me to calculate some values for work and the way I want it requires me to do it with a pair of drop-downs.

Take a look at it he

http://www.projectvoid.co.uk/

I would like to select the first drop-down, on the left-hand side (Current Lighting Products -> Type of Lamp) and for the right-hand side to copy it's selected value (Energy Efficient Products -> Type of Lamp).

Furthermore, it shouldn't interfere with the fact that I'm also using those values with my dependent drop-down, below (Wattage).

The only piece of code I've found that might help is this:

Code:

function setSelect(name1, name2) 
{

var select1 = document.forms.formname.elements[name1];
var select2 = document.forms.formname.elements[name2];

select1.selectedIndex = select2.selectedIndex;

}

I am also unsure how to utilize it.

I look forward to your aid! Thank you in advance.
