I am a newbie in html. My scenarios goes as below.
I have a drop down with values. My need is to navigate to respective webpage(which I have created for each values in the dropdown) on click/selection of one value.
Help me in achieving this.
I think Javascript is needed for your case...
<select onchange="document.location.href=this.value;">
<option value="https://www.stackoverflow.com">Stack Overflow</option>
<option value="https://www.google.com">Google</option>
<option value="https://www.instagram.com">Instagram</option>
</select>
I have a simple form with some select options that need to do stuff when the options are changed (create new form elements). This all works fine, however when a select option is chosen and the user clicks elsewhere on the page (either another form option or a blank area of the page) the text of the chosen option remains highlighted blue.
I've used select's before and not had this problem, however they weren't linked to the .change function. Is that something to do with why this is happening? Has anybody encountered this issue before? All help greaty appreciated! Code is below...
<div id="container1" class="form-group">
<label class="control-label">Select an option</label>
<div>
<select class="form-control" id="mySelect">
<optgroup label="A">
<option value="1A">Option1A</option>
<option value="2A">Option2A</option>
<option value="3A">Option3A</option>
<option value="4A">Option4A</option>
</optgroup>
<optgroup label="B">
<option value="1B">Option1B</option>
<option value="2B">Option2B</option>
<option value="3B">Option3B</option>
<option value="4B">Option4B</option>
</optgroup>
</select>
</div>
</div>
I've seen the issue brought up here
Remove Blue highlighting of option
However I don't think this quite describes my problem, as it seems to me that that person wants to remove the blue highlighting whilst using the form (hard to be 100% sure though). I don't mind the blue highlighting being there when using the form, I just want it to stop persisting when you stop using the form and do something else on the page.
UPDATE: Problem only seems to occur in Internet Explorer (tested versions 9, 10 and 11). Tested in Chrome and issue doesn't occur. Just to elaborate on the comments, the issue has nothing to do with JS (so I have removed the JQuery code and subsequent tags). The issue occurs when using optgroups in a select form. Loading the HTML outlined above into IE produces the error.
I am not able to search for a solution for this in google. Maybe some will help me here.
Here is the HTML code for the combo box, I need to choose Application Acknowledgement
<select class=”form-control” data-bind=”options: UniqueCorrespondenceTemplates,value: SelectedLetter, optionsCaption:’-- select -- ‘”>
<option value=””>-- select --</option>
<option value=”Application Acknowledgement”>Application Acknowledgement</option>
<option value=”Pend”>Pend</option>
<option value=”Withdraw”>Withdraw</option> </select>
after that, two buttons will appear, Validate and Cancel..
Here's the validate button
<button class=”btn btn-success” data-bind=”click:validation,
visible: $root.canShowValidate() && !$root.ShowConfirmation()”>Validate</button>
I tried looking for the classname, but I does not appear in the loop. Maybe I did wrong. the code I used is in the office. I also tried parent.exep, the javascript trigger, gives a error. I found at google that this is a knockout js, but I don't know what that means.
Can anyone help me call/trigger those dropdown menu and button?
I am using a SELECT2 Input box. I need help trying to change the color (to white) of the "X" that would remove the tag from the field. I have included a fiddle with some sample code.
The below is just some sample code. I am using an input box with angular utilizing ui-select2 functionality. I figure is someone can figure out below, I can at least translate it to what I need. Thanks!
<select multiple id="e1" style="width:300px">
<option value="AL">Alabama</option>
<option value="Am">Amalapuram</option>
<option value="An">Anakapalli</option>
<option value="Ak">Akkayapalem</option>
<option value="WY">Wyoming</option>
</select>
<input type="checkbox" id="checkbox" >Select All
Some Script:
$("#e1").select2();
http://jsfiddle.net/jimfromthegym/jEADR/1112/
It appears that the "X" is actually an image: select2.png
If you check your browser web tools network tab you can see this external resource loaded.
I'm assuming it is part of the select2 plugin you are using. If you can find this image in the source of the plugin and change the color manually using an image editor that would be your quick fix/change.
I have a very simple select drop down. In Chrome, it doesn't drop down. The code itself works fine, and the drop down works in Safari, but for some reason it won't open in Chrome. Here is the HTML:
<select name="pellet_credit" class="item_discount">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
It should be pretty simple. It's a dropdown... Here's a screenshot of the select, selected, but not open:

This is a jsfiddle with the full source included. The dropdown works for me in the jsfiddle view, but not on the actual site.

Other drop downs on the page work fine.
Validate your HTML to make sure there aren't extraneous closing/end tags. Make sure you aren't hiding the options through CSS as well.
I had the same problem with Firefox and Chrome and due to the z-index of the form being -1.
When changed the z-index, it worked fine.
This happened to me when I put a <select> inside a jQuery .sortable() element. I copied this code right off the jQuery website, and the .disableSelection() method call killed my <select>.
$(function() {
$( "#sortable" ).sortable();
$( "#sortable" ).disableSelection();
});
Once I removed the .disableSelection(); (which oddly enough they've deprecated...) everything worked just fine.
I think you should set a value for your options
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>

what ended up happening to me that caused me to be on this page is that display was set to display:none; on the option elements
solution:
$(yourdropdown).children().show();
We had a crazy problem when we were developing a client/server programming language which had a listbox. Although INPUT worked the listbox didn't. We have mouse tracking on it and by a bug the $(window).mousedown... was being enabled by default.
We were able to track the problem with this page: https://hackernoon.com/finding-that-pesky-listener-thats-hijacking-your-event-javascript-b590593f2a83
Just in case the above page disappears:
In Chrome (possibly other Chromium flavours [works on Opera too]):
Right click on element.
Click 'Inspect...'
When the 'Elements' are shown, the right panel will have [Styles][Computed][Event Listeners] (tabs). Click on 'Event Listeners'.
Look for 'mouseup', 'mousedown', 'keyup', etc and expand what you suspect and remove it to see if that fixes the problem (debug).
Change the code.
What we did was change the 'return false' to 'return true' in our code.
To debug such issues try removing all attributes from the html and add them one at a time to find out what is causing the issue.
For example, the snippet below does not work as needed.
<select size="10">
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
</select>
Removing the size attribute fixes it
<select >
<option value=1>1</option>
<option value=2>2</option>
<option value=3>3</option>
</select>
I'm adding an answer just to call out the comment by #Agos in the selected answer. Check if you have event handling code (mousedown, click, etc.) that might be stealing the events from the dropdown.
The problem for me was that I had included class names in the id declaration.
For future audience, notice in particular if your select element is inconsistent with the surrounding form styles. This is a likely clue that a class isn't being applied correctly, and you may have accidentally placed it in the wrong spot.
