I have a form that has a drop-down of dates. What I want to do is for the dates to not appear until another drop-down has an option selected because this other drop-down will determine what dates show and what ones don't.
I have created two drop-down menus one without the dates that will display until the other drop-down has an option selected and another with all of the dates in. How can I get this one to appear exactly where the one without the dates was?
I am a novice when it comes to jQuery and JavaScript I have tried a couple of basic things but it doesn't seem to be working.
Can anyone help me please?
You can use jQuery change event
$("#form").change(function() { // some logic here });
Here is jsfiddle demo http://jsfiddle.net/a92b40w9/
Here you can get some smart stuff about events in jQuery https://api.jquery.com/category/events/ pay attention to those associated with form and input

I wanted to create a simple multi-select dropdown which displays days (mon,tue...sun), select all, unselect all...using angular JS, bootstrap,JS.
I wanted to write controller in a way that if i select monday twice, it de-selects and remove it from the selected items....instead it is keep on adding the elements again and again...and unselect all is not working.
I tried every other way and couldn't succeed. Plz help me or share any similar code that can give me a idea.
PS: I don't want to use jQuery for this.
Check out the following:

The second link seems to be exactly what you are looking for.
Currenty I am using checkboxes to select more than one value in a form. So when creating a new post I can select all the categories it falls into. But the cat list is getting longer and is becoming a bit unmanagable.
I like how wordpress adds tags to each post via ajax. Wordpress has a text input field with autocomplete, you just start typing and then if it's already there (in the db) then it'll show and get adding to a list dynamically. If it's not found in the list then it gets inserted on form submit.
How can I achieve this or similar so that I don't have to use x amount of checkboxes?
Check out this jQuery library. It works on multi selects instead of checkboxes, but the logic and result is exactly what you need.

(not affiliated, I've just used it a few times)
One option would be to make use a library such as jquery-autocomplete
https://www.devbridge.com/sourcery/components/jquery-autocomplete/
This makes use of AJAX based functionality and will give you the ability to tweak it based on values stored in a database table. You can make a simple check function that, in the case the value can not be found, the user will have the option to simply press add and insert it into said library.
The rest is jsut a matter of styling and design.
I am working on creating a website using node.js and express. I want to add a multi-select dropdown box. I have a Javascript object which contains a variety of properties and would like to populate the dropdown box with all the property values. I would also like to be able to add new options to the dropdown and have them visible without having to refresh the page. Is there someway to accomplish this? Perhaps using JQuery? I would appreciate if someone could provide an example.
I've tried this example, but I would like to have a multi select checkbox for the dropdown. The example requires the user to press ctrl while clicking to select multiple options.
Thanks!
$("#select_id").append("<option value='value'>name</option>");
I saw this post:
How can I highlight certain options in a HTML select using jQuery
which is similar to what I need to do, except a bit too complicated for my understanding. In the html body, I have a dynamically changing select form. The user can select multiple items from this form, and click a button ("Display") to run a javascript function. This function already goes through the list to determine which ones have been selected and uses the information somewhere else.
I would like it so that when the user clicks "Display", the items that were selected will be highlighted (and each with a specific color).
What do you think?
Yes! I figured it out.
myList.options[i].style.backgroundColor='yellow';
IN my case i want to implement multi select auto complete combobox using html,javascript.
Is there any body who knows how to implement it.
Which will be similar to text field shown in stackoverflow while adding multipal tags to any question.
If you are talking about multiple drop down boxes that are linked, so that the selection in the first drop down menu determines the possibilities in the next, then the ASP.NET Toolkit has a nice cascading drop down sample. This will only, of course, come in handy if you are programming in ASP.NET. I would not recommend trying to reverse engineer the solution.
What do you mean by auto populate?
If you want to populate the drop down box dynamically you can just use a normal HTML Select tag and use Ajax to fetch the list of values to be shown in the drop down
