Select Boxes Switched :: The Color Option Would Return To The 'selected' Position?
Mar 3, 2010
Here's what I'm trying to do is...If you select a color, then select a shape, the color option would return to the 'selected' position.If you select a shape, then select a size, the shape option would return to the 'selected' position and so on. The end result is I would like to have only one item selected from one of the select boxes, with the other two select boxes returned to the selected position.The code is presented here.
I wish to identify the option chosen in the function but not by its value, by its position:
<script> function goHere(){ var s = document.getElementById("input");
[code]....
I was hoping that variable "u" would be either 0, 1, 2, or 3.How can I get a variable to alert me the position of the selected option in the form? I think it is elements[i].
I have more than once wanted to manipulate the contents of select boxes dynamically, whilst the boxes contain <optgroup> tags. Manipulation of a select box containing only <option> tags is fairly easy and there is plenty of material on the net to assist with this. However, I have searched long and found the material on the subject of <optgroup> to be sparse, with a few posts here & there, but basically you're on your own.
After much trial & error regarding techniques for this, I have a fairly generic solution, which I decided to share, and the code is below. Two different scenarios I have come across are (1) altering the contents of one <select> dynamically depending upon another, and (2) being able click 'up' and 'down' buttons to alter the sequence of the listing (whilst keeping each <option> within its respective <optgroup>) I tried various solutions for both of these which tended to either trash the screen, alter which <optgroup> an <option> was under or trash the <optgroup>s altogether.
Both these situations can be handled with the solution here. Basically I keep the <optgroup>s and <option>s stored in an Array(), and then use the Array() to reconstruct the <select>.
To use, just manipulate the Array() in memory - which I find very easy - and then call the function to reconstruct.
I like to build the <select> <optgroup> <option> set using HTML as normal and then create the Array() with <body as this makes it usable where javascript is unavailable, rather than have the Array() as a hard-coded start point. Code:
I'm currently working with a bit of javascript to dynamically add <option>s into a select box. My code currently works fine in Internet Explorer, however in Firefox the dropdown only displays the first option in the list, and when clicked the other values aren't displayed.
Here is the code;
//ar_options is an array with the option to be displayed in.
for (count=0; count<number_of_options+1; count++) { document.forms['enquiry'].enquirytype.options[count] = new Option(ar_options[count],ar_options[count]); };
As I said - fine in Internet Explorer, but not in Firefox. I did discover some discussions about this, which were talking about an issue and workarounds but I couldn't get any of them to work. I have also tried simply using the document.write() function to output the HTML in the correct place. However this is just hte same, works in IE but not Firefox.
In the code below I want to alert the selected option of select. In Mozilla the code works (If I choose "3" alerts it). In IE alerts: nothing appear --------------------- <script> function hi() { d = document.getElementById("day").value; alert(d); } </script> <select id=day onchange="hi();"> <option>0 <option>1 <option>2 <option>3 <option>4 </select> ---------------------
I have a little bit of a complex script where I have a <SELECT> that is pre-loaded with options that are loaded from a database in PHP. But, when this page is loaded the <SELECT> is disabled, and is only enabled when an onChange() is triggered on another <SELECT> that is situated on the same page.
Anyway, when I enable the <SELECT> I would like to have one of the <OPTION>'s selected (instead of having a blank <SELECT>).
The line of JavaScript that I have so far (but isn't really getting me anywhere) to try to select an <OPTION> when the <SELECT> is enabled is as follows...
I am making a usermanagementsystem and working with access levels. I been trying to make a script that when it does a post request and get data in return in json to choose default selected option in a select input. I been trying for two days now all different things. This is what I got that somewhat works. Any ideas how to make it select the right option?
="theOptions1 " name ="theOptions1 "> <option> [Code]....
I want to pass it to a function that will show me the selected element: $(function() { $('#theOptions' + 2)).filterOn('#theOptions' +1, { 'a': ['a'], '1': ['1'] });}); here is a part of the function:
I have a select control that has over 400<option></option>. To cut down on the user having to scroll through all 400 options I have included a text control that acts as a "Quick Index" and with each char entered into the text box the options are narowed. The problem I am having isthe once I have determined which option should be selected, how to set the option to value of "selected"
I have a drop down with approx. 200 <option> elements, each option element has a value such as value="1", value="23", etc. Given a list of values, such as 5, 34, 43, 68, 123, how can pass those values to a function and then insert selected for each corresponding element?
I'm assuming it's possible to change the selected option of SELECT box with JavaScript based on the value and not index, but my searches have turned up nothing that seem to address this. It may be my searching terms, but if someone knows how to do this, could you post some code samples?
I am putting together a form for people to view their profile. The form includes dropdown/select elements to get the users Occupation/Job Title, Organization Type and also their State/Province.
For the profile form, I would like whatever value the user has stored in the database to show up as the "selected" option within the select element.
When a user clicks "Add To Basket" I need some javascript to check that the size option they have selected is not "-" in the form before the actual form is submitted. my form is like so:
I tried using the following code to check if the user has selected a particular option in a single select drop down has been selected, then add a class to a div to display it but it's not working and I can't figure out why. I've tried a ton of other things to but this one seems to make the most sense.
if ($("#existing-subscriber option[value='Yes']").attr('select')) { $(".information").toggleClass("show"); }
cna anyone tell me how to use the Select = "selected" option for a simple dropdown. for example when someone chooses c it will have a code like <option selected="">c</option> (am I doing it right, well if you got a firebug some site with dropdowns offers that option) so can anyone tell me how that works. I will be using it for a purpose of just selecting parts on my array, well incorporating it
When user select, for example, option 3, how can i find which was the previously selected option? etc... I've found some javascript example that evaluate "previousIndex" property of the select element but it doesn't work at all
I am trying to display a rel of each option as they are selected into a div below it . There are several selects of classProductAvailability on the page. When one of the selects changes, I'd like the value of the rel of the selected option to display.At first it seems to work, but only if you start by changing the last pull down menu. The trouble seems to be in the"select.ProductAvailability option:selected", this needs to be written for this instance, not all of the selects of that class on the page. How do I write that, I've tried$(this+" option:selected") but it won't take.
I am trying to extract value of a dropdown on select and use it in a function. Jquery has .each method to loop over matches, but I just need the first match. I could use each and break loop after first run, but there must be a better way..
I have four html form check boxes.The user is allow to choose one or three of the check boxes, the last check box has a value of None.
Example: What's your favorite color.1. Red 2.Blue 3. Green 4. Gray. 5. None.The user can select more then one color.So I'm wondering how can I make the other check boxes deselect when the user click None.So if the user select None, then the other boxes cannot be checked. know you can do this with radio buttons but I would like the user to select more then one option.
