How To Run Multiple OnChange Events On Page

May 27, 2010

I've done extensive searching, but each example or explanation I come across is too different from my own, so it's ultimately no use. The problem is that I barely know anything when it comes to Javascript, but yet I'm trying to use it. I have a form on a page. This form contains 6 <select> elements, each with its own <option>Other</option> element. If something isn't listed, the user can choose "Other" and then type into a textbox which appears.

I have the following code, which works great if only applied to one <select> element.
<select name="How did you hear about us?" id="How did you hear about us?" onchange="makeBox1()">
<option value="0" selected="selected">-- Select --</option>
<option value="1">Search Engine</option>
<option value="2">Referral</option>
<option value="3">Trade Publication</option>
<option value="4">Vendor Web Site</option>
<option value="5">Your Company Website</option>
<option value="6">Direct Mail</option>
<option value="7">Other</option>
</select><div id = "inputBox1"></div>
<script type = "text/javascript">
function makeBox1() {
var a = "<input type = 'text' name = 'box1' id = 'box1' class='form popup'>"
if (document.getElementById("How did you hear about us?").value==7) {
document.getElementById("inputBox1").innerHTML = a;
} else {
document.getElementById("inputBox1").innerHTML = "";
}}
</script>

I've read that you have to combine onchange events, but I have no idea how to do this (I've done plenty of trial and error, trying to make every item unique, but to no avail.

Linking A Single Img To Multiple OnChange Events?

Mar 16, 2010

I am trying to tie the value of an image src to two onChange events. the events are drop down boxes in a form. I do have a couple of single event driven peices working so I think my logic is sound. I originally tried to do this with multiple if statements that tested both conditions/events. I have since given each event it's own function. I have no idea what i am doing wrong. the onChange events have no effect on the image display at all. The default image just stays in place. My JS knowledge is limited but it looks correct as far as I can tell. What am I missing.Here are the functions:

Code:
function dropdownimageMidC()
{

I got a very good select script that produces multiple values and it works fine by itself but I have two other instances of the same script on the same page. I know that multiple scripts don't work on the same page unless you execute the onChange for all three. But I dont have a clue how to do that. Code:

I've got 2 pages: a current events page and a past events page the current events page loads fine as there is only about 10 events the past events page takes about 30 seconds to load and will crash if u click your mouse in the loading time.

The pages are near identical the only difference is the query that selects the events (> versus <)

The page loads immediately without:

OnClick Or OnChange Events To SQL Record

Oct 5, 2011

Have an asp page that user selects a week from date picker and it returns data from sql table in a series of checkboxes for overtime availability. i.e., for the week of 10/10/2011 the checkboxes are Monday through Sunday, the user clicks the checkboxes they want to work overtime and hits a submit button. Let's assume they chose Monday and Wednesday. If they go back to this page later and pick the week of 10/10/2011 the sql table shows checked in the Monday and Wednesday checkboxes.

They can then make any changes they want, hit the submit button, and that sql record is updated with the new data. So on to the issue. For audit purposes, there is another sql table called ot_audit. What I want to do is every time one of the checkboxes is changed (pre hitting the submit button), I need a new record added to the ot_audit table. It will show a datetime stamp, who made the change, what was clicked, and if it was checked or unchecked. I'm new here and all I know is there are onChange and onClick events. Lost after that.

JQuery :: Select Appropriate Row For Updating Onchange Events

Jan 4, 2011

I have a button which creates a clone of the current row. Within each row is a drop down box for which the users can select red or yellow, which represent soccer cards. Based on that selection it calls a function which populates a div tag with the appropriate drop down options for that card color. The problem I am having is that the function is updating all div tags with the drop down selections and not the one for my current row. Please note that the drop down selection box is not guaranteed to be the last row in the table. The referee could go back and realize, that he or she made a mistake and make a change to the second row. So I need this to always be applicable to the current row of editing.

Multiple Events For Onclick

Jan 23, 2010

I have several pages, each having a button and a textbox. The button has an onclick event directly coded into the HTML markup.The textbox has a onchange event in a similar fashion.What I need to do is create a small javascript snippet which adds another function to the onclick event of the button, and the onchange event of the textbox.I am not allowed to make any changes to the HTML of the pages, or the functions which are called originally by the events.All I can do is place a small javascript file in the head section of the pages.

The code should attach another function which is called during the event, while at the same time preserving the current function attached to the event.

Ajax :: Calling Multiple Functions With OnChange?

Feb 25, 2009

I have a series of dropdowns that allow the user to choose country, province and town respectively. The province dropdown is populated by an Ajax function when the user chooses their country, and the town dropdown is likewise populated by the user's selection in the province dropdown. This all works fine.

Of course, my client now wants to add a "major centres" dropdown between the province and town selection. This seemed straightforward to me, however in practice it's proving problematic. The "major centres" are drawn from the same dataset as the towns, however an extra flag is applied so that only records flagged as "main centre" appear.

Called separately , both the town dropdown and the main centre dropdown are populated. However, the problem comes in when the onChange event which is meant to update both dropdowns simultaneously fires. Watching the network behavior in Firefox, I see that calls to the ASP files which populate the town and major centre dropdowns DO happen, though only one of the calls actually returns values. I've checked this in IE7 also, and the same thing happens.

My function is called from the Province dropdown, like so:

Code:
<select name="Province" id="Province" onChange="callOthers(this);">
<option value="">---</option>
</select>

[Code]....

what might cause only the one dataset to be returned via Ajax? Either the towns are populated or the major centres, depending on which order I call the two handleOnChange functions from my callOthers function. As I said, BOTH Ajax calls are made, however only the results of ONE are being used in my page. Could this problem be related to 2 Ajax calls being made too close together?

Onclick Events For Multiple Fields

May 30, 2009

I am working on a simple control panel where I have text input fields in which a user can click on a text box and the text will automatically focus and select. I have done this fine. However, when I use the same onclick event for multiple fields, only the last one created works. So, if I were to comment out the password and email field additions, then the userName field would work correctly. If I were to just comment out the email field, password would work correctly but userName would not. And finally, if I have the code as is, userName and password do not function correctly while email does.

JQuery :: Best Way To Bind Events To Multiple Elements?

Jul 5, 2011

Im working on a ajax app and not sure what is the best way to bind events to elements (performance wise).I have a number of elements with 'click', 'focus', 'keydown' events which can be assigned though the delegate to the parent, like so:$('#parent').delegate('#child', 'click', func.....)but is it better to add a delegate to the 'document' for multiple events and use IF statement to filter for elements which should fire an event, like so:[code]Each element can be replaced with an updated version retrieved from the server.

Multiple OnClicks Events Aren't Working Together?

Feb 14, 2009

I have a simple javascript overlay (like a lightbox) with a message that pops up. The user is meant to click a button, see the overlay thanking them for their vote, and then be redirected to the affiliate page (its a poll site) after about 3 seconds. I have everything down, except, it will either display the overlay as one of the onClick events, or it will do the timedRedirect but not both. I've tried putting the redirect before and after, and when its before it redirects, when its after, it shows the overlay. How can I do a timed redirect and show this message?

<script type="text/JavaScript">
<!--
redirectTime = "3500";
redirectURL = "http://x.azjmp.com/2KTCs";

Process Of Handling Multiple Mouse Events

Jan 8, 2010

If you've caught a mouse event (say, onmousemove) and you're currently in the process of handling that event, is it possible for that, or another, mouse event handler to get hit again, at the same time that you're handling the previous event? Or is it guaranteed that no additional events will actually call any of your event handlers until your code returns from handling the prior event? That is, is it strictly sequential processing, or can they occur simultaneously?

Blur Function - Multiple OnClick Events?

Dec 29, 2009

I would like to open a window "under" the current window (So it doesn't open on top). I think this can be achieved using the .blur function.

So something like:
<a href="#" onclick="openWindow [URL];this.blur();return false;">Open website</a>
(Obviously this doesn't work)

I've seen ways to do it, if I'm using 1 url, but because I have a list of 30 different links, I can't simply use:
Code:
<SCRIPT LANGUAGE="JavaScript">
function goNewWin() {
TheNewWin =window.open("somepage.html");
TheNewWin.blur();
}
</SCRIPT>

Which is why I need something that I can use on each different url individually that opens a new window under the current one.

Assigning Pre-defined Texts Onchange To Multiple Input Fields?

Feb 19, 2010

The simplified code below works, and should give you an idea of what Im trying to achieve. The final version will have dozens of input fields so you can see why the below method stinks :D

<html><head><title>Values</title>
<script type="text/javascript">
<!--
function getid() {

[Code].....

Each text input will have A or B written in by the user, which should automatically place that letters associated ID in its partner field. If any other letter is entered the ID will automatically be left blank.

With the above code I'd need to repeat it over and over for each of the dozens of input fields. The final version wont be using simply A/B either but around 50 possible inputs each with their own ID which would make around 1000 possible variations.
