Remove (not Disable And Not Delete) An Option In A "select" List
Nov 29, 2010
Is there a way to remove (not disable and not delete) an option in a "select" list, and restore it later when needed?
I have a form with many huge lists ("select" with many "options") that depend on eachother. I am dynamically updating the form through server, and wish to update the list values by sending a mask string. This way I could remove and restore the options without the need to pass the whole list again.
I tried many ways but none work:
* option.diabled="disabled" is not good because it is still shown
* option.style.visibility='hidden' is not good because it is still taking a row
* option=null is not good because I will not be able to restore it
I need a method similar to the following one for remove/add fields in a form:
trying to remove one or all elements of select options fails for Pocket Internet Explorer. Is there a way to do this?
if is_PIE { // this does not work on Pocket IE while (opt.length) { opt.remove(0); } } else { # IE 5.+, Moz, FF, Galeon, Opera, Konq # remove everything at once opt.length = 0; }
Tried doing this a few different ways but it seems no matter what I do the last option won't remove for some reason.. if it's the only option, it won't remove either. as it's the last one.code...
I have some fields and a Select option as below, I want to add a new field if I select "Add" option, and remove field when I select "Remove" option, can I do it in very simple JavaScript? my code will be has a error, can you fixed it for me?code...
I have a form that uses jeditable to edit-in-place several fields and select boxes. Everything is working great. Now I need to a way to add a new option to the select list. What I would like is the user select "Add New..." from the select list that would pop-up a dialog window where several fields are filled in. When the form is saved the select field is updated with the new ID and description. I use Facebox for pop-up windows to display notes when the user clicks on a topic. I know Facebox can be used to display a form. It would be ideal to use this ability when creating a new option for the select box.
So then I have some JavaScript code, that automatically determines which state you're in. My question is, how do you get JavaScript to select the state the code has determined you're in? I tried these, to no avail.
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?
If i have a drop down list on my website, and i want to use javascript to change its selected value,however, i do not have the id/name attribute of the option i want to select, only have the "value" attribute of the option, can it be done?
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
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 have an select option list, each option has a numerical id, value and text. Each option has an array of its own. So when I choose an option from this list, I want to insert the options array into another option list with an id, value and text. Whats the best way of doing this? How do I select an array based on the value or text of a select option? For for example, take a list of car makes. If I choose the make Audi, how do I select the array of Audi models and insert these models into another select option list. All makes and models have their own numerical id, value and text.
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.
I have a list called drawPathList thats just a list of xy coordinates. I use this to construct a drawing on a map. However, people would like to be able to 'Undo' something that they have drawn, so I'd like to yank that last item in a given list.
drawPathList looks like this: 23,34||45,67||456,678||43,78
Can someone help me with a function to remove the last item in the list (regardless of length)?
I have a form, with two drop down boxes. I want to be able to disable the second drop down box when a specific value is chosen on the first. I can't seem to figure out how to do this.
Go easy on me, I'm a newbie for the most part, but here is my code...
How can I disable an option in a drop-down menu? Specifically, I want to disable the option "Bouncy Castles". I want to display it, I just want the user to be able to select it. As well, how can I remove the indentation?
disable select until user puts mark in check box. Then enable select.I have two select box's on a page. The first asks what product, the second is based on the first and presents a list of pdf's according to which product the user selected. (yes, multi dimensional)What I have works fine, but now i need to make the user put a check mark in a check box before the First SELECT box becomes enabled/available.So basically, when they agree, they can get the download.Here are my select boxes.
HTML Code: <form> <select name="category" style="width:180px"></select> <select name="site" style="width:180px" onchange="openLink(this.value)"></select>[code]....
(ignore the The 'open' button. It's there in case the default option is what the user wants, so they don't have reselect via the select box.)
1. How do I disable the select boxes by default on page load?
2. How do I detect that the user has put a tick in and the enable the disabled Select box?
