Allow Selection From List If User Select At Least One Checkbox
Apr 14, 2010
How do we use javascript to only allow selection from the list in question 3 to be made IF the user selected at least 1 check box in question 2?
Below is my code:

I've got the following code snippet in a function to set a coockie based on whether or not the user selects a checkbox. Using an alert the cookie text looks fine but when I go to retrieve the values the only one it can find is the value for user. I've a few different things and none of them seem to work. I'm getting the same thing in both IE and Firefox. The only cookie listed is the 'user' with the proper expiration date. Code:
I have a ColdFusion page with a select drop down list. On submit, I'm storing the value in a cfparam and trying to use jQuery to auto select that particular option. Currently I'm using :contains but this is unacceptable because it selects the last item that contains the cfparam.
$("option:contains('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected'); Is there something like this: $("option").equals('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected');
[Code]....
I willconsider other alternatives to accomplishing my objective.
I am trying to create a web page in which the contents of one selection list depends upon which element in another selection list is chosen, but where the information to populate the first selection list comves from an SQL database on the web server.
There are a couple of these situations in my application but, for example, the first list might be a list of counties, and the second list a list of states/provinces. Obviously the names of counties depend upon which state/province is chosen, but there are too many possibilities to be able to embed them within the web page itself. So when the user selects a state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example it is suggested to use <script src="a URL"/> to ask the server side code to send up data of type "text/javascript". However the examples do not seem to address how the server side code would know which state/province the user had selected.
If there is a web site that addresses this sort of thing, I would appreciate any pointers.
I've been beating my head against a wall for a few days trying to get this working. I'm trying to create a dynamic menu where a user selects one item and another select list is shown, then another and another (and so on). Here is my JS, it *should* be taking the ID of the div, comparing it to the selected value and then showing another div by settings it's class property to visible:
iam trying to use 5 drop downs in my form for user to select languages and each select drop down should not allow the user to select the same language again and all my drop downs are populating individually from the DB on the page so if "English" is selected for "dropdown 1" then again "drop down 2" should not allow "English" to be selected.
i am writing a script that will update a dropdown list based on the selection of a previous list. the script is run by a PHP script, so instead of posting the PHP, i will post an example client-side script. the hierachy is: category, sub category, brand (but sometimes there exists no sub category and the PHP script queries and adds brands instead) everything works correctly, except for one major issue: you can not change the selection of the third (brand) box this could be an easy fix for some coders, but i am not experienced in javascript and could really use some help. here is an example script, sorry it is so long
I have been struggling on a bit of code for a while now. I need to populate a second drop down list (Region) based upon the selection of the first (County).I have found a piece of code that works on its own and have adapted to suit my needs - see below. However, when I drop it into my main page the javascript is not working. It's because of the formObject but I just don't know enough to resolve this! Furthermore, I need the textboxes the user has already completed in the form to retain their value once the javascript kicks in as the completed form will submit to a database.This piece of code is working well . . . .
<?php
$link = mysql_connect('myhost', 'myusername', 'mypassword') or die('Could not connect: ' . mysql_error()); mysql_select_db('mydatabase') or die('Could not select database');[code]......
I have 3 ASP list boxes. I would like to populate the second list box based on the selection in the first list box and based on the selection in the second list box, populate the third. I would like to do this using AJAX. How can I do it? Can someone please give me the code snippet as I am a complete noob when it comes to AJAX and I kinda am running outta time to finish implementing it. Additionally, should I use ASP boxes or HTML <select> tag?
'trying' to write a checkbox type calculator. How can I do something along the lines of,If 5 checkboxes are checked, apply a 2% discount to the total.I am by no means an expert in javascript. I found a bit of jQuery
Code: $(document).ready(function() { var total = 0;
I've created a dynamic table with a checkbox.I'd like to be able to return the value of the cell in the right column of the checkbox that has been ticked, and then disply the values when the approve button is clicked.Looks something like this:
I've been having problems getting my select option to change the options of another select option. I'm not much of a javacsript coder, so I'm at a lost.When I select the first option nothing appears in the second option.
I wrote an application that generates HTML based on some database record set. One of the HTML generated is a checkbox with NAME=StudentID. This is to facilitate user to select this user for further processing. This also means that ALL student have a checkbox named StudentID. I do I ensure that only one checkbox is selected at any time before the user proceed with the processing of the selected student.
I'm wanting to hide certain divs within a container. If the sub div DOESN'T have a checkbox which is selected in it, then it should be hidden when you click the link. eg: if #2 and #5 checbox only where selected then divs(sub_1,sub_3,sub_4) would be hidden when link was clicked.
I am trying to pass the slection made by a user to a javscript function using the onchange event. The problem is I can get the index but not the actual value. As my list is variable (dependent on a db) I cannot hard code to a static index. I either need a way to determine the number of items in a select control or a way to determine the actual selection made by the user.
Can anyone enlighten me as to the code to determine what option the user selects?
I'm working on a search filter trying to get a form to update itself depending on what options have been checked from a selection of checkboxes. i.e. selecting one checkbox can bring up other checkboxes. It's just posting the form to update_filter.php and putting the updated form into searchNavigation div.
This works for the first checkbox that is checked, but after that nothing.
Is it something to do with the fact that the form is not the same form that it was before the checkbox was checked if that makes sense? or shouldn't that make any difference?
Can we retain multiple checkbox selection upon refresh or using pagination for few hundred records? There is a page where user sees all the items which has search box on the field column to perform searches and select items using checkbox besides those items. While searching the items page result changes and previous selected value is lost. Also the selection is lost when I use the pagination link below the result.
Code: <script type="text/javascript"> /* <![CDATA[ */ function closed_changed(day) {
[Code].....
it should call closed_changed(), which sees if it's ticked/checked, if it is it calls clear_open() and sets the four open related input elements to empty/blank (because a shop can't be open and closed at the same time). works fine in firefox (pc and mac) and safari. not ie7. why not? (the intended clear does happen but only when another subsequent closed box is ticked; it works on the previous day which was ticked; so it's lagging one behind)
