how button click event works in combobox? - javascript

I am trying to dynamically append options in a combo box.
How does button click event work in a combo box element? I am using change event. But I need button click event in the combo box. How can I 'uniquify' the combo box element in jquery?

You are doing it wrong, add a button to add options to a combo box.
OR, add a default option like:
<option value="default">Make a choice...</option>
Then if a user cancels the dialog box, change the selected option on the combo box to default. So, when they want to add another option, they will have to click on the drop down box to choose the - add - option again.

Unselect the select box once isClearable is clicked or true

I wanted to unselect the Input box once the close button is selected after the option is selected
I have attached codesandbox link
Current output
When user select the option value is displayed when close icon is clicked it removes the option but select box is selected unless you click outside, it un-selects the box
expected output
When user select the option value is displayed when close icon is clicked it removes the option and un-selects the box as well.
You are talking about something named 'focus'.
This is actually built-in browser behavior, so if you want it to lose focus in some cases you can do it programmatically using refs.
Here is a link to guide where you can find how to do it

JavaScript - How to save a selected option

I've got a question about how to save a selected options in a select box.
I created a select box with few options, a "save and show" button, and a reset button.
But I don't know how to save the selected items whenever I'm jumping to the page (unless I select the reset button to change my option) .
Thanks for answering my questions.

Jquery: Change select box value and and activate a click state

So whats going on is that I have a site that I have taken on for my work. I have two select boxes I am tying into. The problem is when you click the second select box and choose an option it uses ajax to load a second box next to it (a hierarchical select box). The code that I am using is simple and changes the value of the second box back to the "select" option state when the first box is changed. But what it is not doing is creating click state (sorry if I am saying that wrong) but in order for ajax to bring in and remove the third select box the second select box option needs to be clicked.
Is there a way for me to re-create a "click" of the select box.
Here is the jquery:
$(".state.form-select").change(function() {
$('.hierarchical-select .form-select').val('select');
});
Here is a sample fiddle. See this Fiddle
I am not entirely sure, what exactly you are looking for but I feel that this should do the trick:
https://jsfiddle.net/vuvckm3u/5/
$(".state.form-select").change(function() {
$('.hierarchical-select .form-select option:first-child').attr('selected', true);
});

How to hide the dropdown list in a select box?

I'm working on a little custom dropdown multi-select using JQuery.
What I'm doing is hiding a multiple select box until a seperate select box is clicked - to keep things looking native in the browser it's in.
However, I'm trying to make the multiple select box look kind of like it's part of the normal select box.
So, you click the select box and the multiple appears just below it, appearing to be part of it.
Then, when you make your selections and click the original select box, the multiple box disappears again.
Anyway, this is all working great, except the single option I have inside the standard box keeps appearing on top of the multiple select box.
I've tried using z-index properties to fix this, but to no avail.
Is there a way to hide the dropdown, or essentially disable the dropdown without actually setting the disabled attribute?
You don't have to disable the dropdown, if you're using jQuery you can simply .hide() the multiselect, which basically sets the style='' attribute to display:none;.
$("#your_multiselect").hide(); // .show(); when you want to bring it back.
What I've ended up doing is having no options inside the original select box and having a disabled one in the multi select that says "Select up to 3" so people still see the instructions, but only after the click.
It's not as good, but it'll work.
You can use CSS to hide the option elements in a select box. So you could programmatically hide the options in the first select box while you have the multi-select box up. This will show the currently selected value but hide all options when you click on it.
Here's a short fiddle with the CSS/HTML:
http://jsfiddle.net/LWPL3/
CSS
.hidden {
display: none;
}
HTML
<select>
<option class="hidden">Option 1</option>
<option class="hidden">Option 2</option>
<option class="hidden">Option 3</option>
</select>
From there, you could just $(optionelements).addClass('hidden') to the option elements in the main select box whenever you want to hide them.
