JQuery :: Populating A Select Pulldown Based On The Value Of A Previous Option?
Jul 14, 2010
I'm populating a select pulldown based on the value of a previous option on a pulldown
When I run it on the firebug command line it works fine, but when it is run in the source it does not populate the html with option's for the pulldown.
this is for a test, am not sure what they mean by "do not hard-code the resulting quarter years in the javascript":
Instructions: when a user selects a date from the investment cycle drop-down box, the subsequent investment values must display the next three fiscal quarters. (e.g. for "January 2010", the subsequent quarters will be Q2 2010, Q3 2010, Q4 2010; for "June 2010", the subsequent quarters will be Q3 2010, Q4 2010, Q1 2011.)
Do not hard-code the resulting quarter years in the javascript (empahsis mine...;-)
The subsequent quarters should be presented with checkboxes which are all unchecked.
My markup for the checkboxes:
The values to populate the checkboxes (value and label) have to be hardcoded somewhere, no? what am I missing?
(and, since markup doesn't change when u set value for chkbx dynamically, how do you check that you have set correct value for the checkbox? (don't know if it shows in Firebug, since don't know if code have there now is correct (have this funky code in there for now.. not sure how to approach this...$('#checkbox1').attr('value', 'Q2 2010');
And how do I populate label? (<label for=""....></label> -- do I need to give label an id? or can you grab "for" attr for a label with jQuery?)
I'm using the following code to remove an option from a select control based on a selection in a different select control and the option text in the select option that is being removed. The code works as I want it to, but I would prefer to use the option value for identifying the option to remove instead of using the option text. I've tried several different ways to do this, but can not find the proper syntax.
Not sure if this should have went into the php or javascript forum. I am trying to setup a script that will automatically population a html selection option based on the choice of the previous selection. If hard code everything it will work fine example manufacturer is currently being populated dynamically when the pages loads. The issue is I am can't pass pass the manufacturer variable through to be processed to only retrieve the models for that manufacturer. The code also uses a standard ajax script which httprequest in it.
My mission: Open/collapse TD cells based on items selected in a list box. Getting no response from jQuery so I've done something wrong but cant quite get there. Listbox 'mainselect' contains option values that refer to names of TDs in a table. When a mainselect option is clicked, it will toggle to open or close the referenced TD list box by option value. Does hide/show make a TD 'blank' or actually set it's width to '0'? I want it to close, moving other cells left.
I don't know if this is something you could do without JavaScript, but anyways... I want to make a drop down menu that changes a form based on the option, like if I chose Option1, it would show Form1 and so on.
Is there some example js that shows how to populate a text field on a form, based upon what option is chosen in a select form field? The options can be hardcoded and it would be great to also have a default if js is off on the client side.code...
I want a page to have a different item pre-selected in an option menu-button according to the parameter at the end of the URL. Eg if the URL ends in "?choice=Beta", the item that says "Beta" should be pre-selected. Here's what I have so far:
Code: <script type="text/javascript"> function show(choice) {
what would be the best way to have a hidden array of possible text directed at a textarea and then if something is not within that array "onfocus", a certain select option is chosen within that form?
This code block occurs several times. Sometime the first div ist just "inner" and the second div is missing.
Now I need to update the "new" DIV based on the height of the previous inner-new DIV. For one it works fine:
var height = $('#inner-new').outerHeight(); $('#new').css('margin-top', height*(-1)-30);
But how could I re-use this universally for all my boxes. It needs to check if the DIV "box" contains the DIV "inner-new" as first element, if that is true it need to update the DIV "new".
I tried several things with $('#box').each(function(i) { ... }); but couldn't come up with a solution.
I have a site that can consist of one or several (up to 20) select boxes that all list the same data (TeamID, Team). There are about 8000 list items to be loaded in the select box.This data is fetched in a seperate file using php+sql and with javascript and ajax, I populate the boxes. Note that these are populated on page load and not based on a specific action/change. The script looks for select boxes that have the class="ajax-team-list". Well, the above works. My drop-downs are being populated. However, it takes an insanely amount of time (30 seconds in IE). Skipping the javascript and only using php to get the same output takes 2-4 seconds, so something must really be messed up in the code, or?Any ideas, suggestions or thoughts about an alternative solution? For whatever reason, Firefox loads the above code in 2-4 seconds, Chrome takes 12 seconds.. and like I mentioned, IE takes 30 seconds.
With IE 8 when a select element is created and populated the select element appears as if it doesn't contain any options until it is clicked. Once clicked the select element then resizes and the data is displayed. I ran across an article mentioning this issue could be resolved by adding an extra line of code that applies a "blank" style to the element but unfortunately the issue still persists. I'm currently using jquery 1.4.2 and the code I use to populate a select element is:

I'm trying to populate select boxes depending on choices in other select boxes. In my case, the person has to choose a type of fixture type, then a select box with all the models would populate, and then a third select box with the watts have to populate.
In my code, the second select box is populating, but the third one is not. I'm sure that the problem is not in the php, but has to be in the jquery side. I'm a newbie in jquery and javascript.
I have a property site and I currently have it set up do that when entering a property the person selects a country.Depending on the country selected, the town drop down populates with certain towns in that country.ecause of the number of countries this javascript is pertty large and that worries me slightly. Also, if someone hasjavascript turned off then it doesn't work.In order to make it more accessible, would I have to seperate the form into 2 sepertate pages.
I was wondering if it's possible to make it so that once a user selects a certain option in a list, it makes the next input for that form change to either a textfield or a list without losing the values entered in the inputs above.I know PHP is a server-side script, does that make this not possible?
I need to put previous/next navigation button images on a lot of slides.If i am on slide 3 I'd like javascript to identify previous button as slide2.html and next button as slide4.html and so on
According to [URL] intended way for jQuery to change dynamically the selected option of a dropdown select control isassigningthe desired text instead of the value. I found this way veryinconvenient (data structures usually deal with value codes, not value descriptions) and it seems to work only sometimes.
Trying different options I came out with this approach that seems to do the job so far:
function setSelect(pID,pSelectedValue) { $('#'+pID + ' option:selected').removeAttr('selected');
I don't know what it is I am doing wrong, I am trying to get the menus to either expand or contract based on their previous states, i.e if already expanded if clicked again contract, and if contracted, expand, so far it doesn't work for the about and services link(but works for the expand all and contract all links), Code:
I have spent the last 6 hours working on this, and I am about to lose my sanity. I need your help very desparately. I want to create some radio buttons for building a computer for a class project. Basically, what I have now is the radio buttons in separate groups, and a function that calculates the total price of the items selected. But what I am finding impossible to get is this: I need to set it up such as that if you select a radio button in one group, it disables part of the second. What this means in my work, is that say I choose AM3 as the CPU socket, only AM3 motherboards and processors will be enabled, and the rest in these categories will be disabled.
I am trying to set it up in a way that when you first open the page, cpu, motherboard and ram groups all disabled, then based on your socket choice you get different options for motherboards and processors, and then based on your motherboard choice you get different choices for RAM.
I am creating a form in which a checkbox is checked based on the info from previous page.The info I am passing is the client ID (which is a number I can pass in the URL variable)In the form I have a list of clients (with checkboxes next to them)Now if you come from a specific client page the checkbox with the client name should be already checked since you are getting info regarding that client, with the option of selecting other clients.So any idea on how I can accomplish this using Javascript?
