Need to clone select box from previous one ( ie, add select box 'n' number of time from the previous one )
But when I added each time, all the previously selected options should not be available in the cloned select box list.
$('.field_select_box_list').each(function(){
$(this).find('option:selected').remove();
});
This code removes the parent select boxes selected option too.. but I want remain them to have the selected option.
any help.
Your clone code can just do something like
$('el').clone().find('option:selected').remove().end()
The .end() causes the selector to return to being $('el') rather than the filtered option:selected selector, so you can continue running things like .appendTo() etc without needing to break the chain.
I think you need use one select_box original, hidden it. Then you can remove with select_box second not hidden or add more element from select_box original.

I have a button that is cloning an element on the page each time the user clicks it. It is duplicating a select list for them to choose another option.
However, its cloning the whole element including the option that was selected so all of the new ones appended have a default value which I dont want.
globalLocales = $("<div />").append($('[name=localeID]:first').clone()).html();
$('select').select2();
Is there a way I can remove the selected option during the cloning process so it doesn't carry over to the new element?
I tried using .removeProp('selected') in the append as well as .prop('selected',false); but that didn't work for me
One way to fix the proble is to select a nonexistent value:
$("<div />").append($('[name=localeID]:first').clone().val(-1)).html();
Or you can find selected option and remove selected attribute:
$("<div />").append($('[name=localeID]:first').clone()
.find(':selected').removeAttr('selected').end()).html();
but this is a little clumsy.
you can remove the selected attribute with this code.
$('[name=localeID] option:selected').removeAttr('selected');
I have a Magento Website. I have two js files, one written in Prototype an one in jQuery.
I have two select elements, with about 10 options. From jQuery I'm changing the first select's attribute "selected" (an some more). In Prototype I have a class that creates dependencies between two select elements.
If I click on the first select element and choose an option with the mouse, on the second select element will appear only the options that are linked to the option I choosed in the first select element. This is allready done in prototype.
The idea is that I want to do the click/trigger automatically from jQuery. The first select change it's selected option. But the second select element display all the options (and should display only the options linked to the first select element).
On the Prototype file I have some Event Observers, and I guess that these observers are not triggered from jQuery:
var select_el = $('select_' + id);
...
Event.observe(select_el, 'change', this.update.bindAsEventListener(this));
Event.observe(select_el, 'swatches:change', this.update.bindAsEventListener(this));
...
update: function(event) { ...
So I need somehow to trigger these events from jQuery, or to set an autocheck in Prototype.
Please tell me what should I do.
I've read on stackoverflow that events from Prototype can't be triggered from jQuery. There should be a way to do that. I just haven't found it.
I've tried jQuery functions like:
jQuery("option[value='" + checkedId +"']").attr("selected","selected").parent().focus();
jQuery("option[value='" + checkedId +"']").parent().trigger("onchange");
jQuery("option[value='" + checkedId +"']").parent().trigger('change');
Where the "parent()" is the first select element. The first select element changes as I want, but the second select element should automatically change after the first select is changed. And this never happens. It works only if I click with the mouse on the select and choose manually an option. I want to do this from jQuery, without being necessary to manually click on the desired option.
Thanks for reading this, and now just give me a fix for this problem.
Regards.
Been trying to work this out for a little while now, no luck.
jQuery("#choosenCause option:selected").removeAttr("selected","selected");
jQuery('#choosenCause option[value="'+json.causeID+'"]').attr("selected",true);
I'm using the above, it adds selected="selected" to the right element, but does not change the selected element that the user sees.
Full JS here - http://inspire.simplyfundraising.co.uk/wp-content/themes/inspire/assets/js/promojs.js
To set the selected option of a select element, use val():
jQuery('#choosenCause').val(json.causeID);
in the first string you need to correct the code - jQuery("#choosenCause option:selected").removeAttr("selected");
the second string works fine as i see
I have a select that has dynamically created option option[0] always ends up being autofocused making my onchange not work if I want to choose the first option.
The index of the options matter so creating a " " option won't work.
Any ideas?
edit: The user creates an object. When the user saves the object, it creates a new option in the select tag. The user selects something from the select tag to go back to that object.
The autofocus is always on option[0] until they selected something else even if they created a new object/option so if they wanted to pick the first thing, but was on the second or third the user would have to click on another option first then click on the one they want.
What I want is that it doesn't focus on any of the options so that they could click on option[0] from the beginning regardless of whether they've selected anything from the dropdown.
Seems like a lot of work to workaround this issue, instead of changing one of your requirements. You say that the index corresponds to an index into an array of objects. Why can't you have the first option blank or "Select...", and then simply subtract one for your lookup into the array?
Or, have the values correspond to the array index, or use custom data attributes to store the array indexes? Seems like any of these would be easier than trying to force a consistent behavior for an unsupported functionality across multiple browsers.
A Select box always has one of its options selected (unless it doesn't have any options). You might need to use a different event (onclick, perhaps) and test the value to see if it has changed.
You can add a default empty selected option with:
<option selected="selected" disabled="disabled" hidden="hidden" value=""></option>
The select is empty by default, with the void option not selectable in the options list.
I have a div that is being used as a dialog with jQuery's .dialog(). This div has a select box with options. The options the user has already selected are displayed on the main page. They can remove options from the main page and can open the dialog multiple times to add more options.
I populate the select box with all possible options on page load, but then when I open the dialog box I use jQuery's hide() to hide the options that the user has already selected and are displayed on the main page. This adds the CSS display:none; to the element in question, which IE ignores on <option> tags and displays anyway.
I can easily enough call remove() instead and remove it from the DOM. However, if the user selects some options, them removes them on the main page, then opens the dialog again to select more options, the options are no longer in alphabetical order, the options that were removed from the DOM and put back in it are now at the bottom since I used .append().
Is there any way to get IE to hide <option> tags? Or is there a better way to do this? Or is there a way to insert in alphabetical order simply?
If you need to remove it from the DOM, you could store the options in an array. One array (or object) for each option list. Then removing options from the list itself is reversable. You can always rebuild the select menu again from the array. Just populate the array once the dom-ready event fires.
Demo online: http://jsbin.com/avuru
$(function(){
// Define variables to be used throughout this code
var colors = [];
var list = $("select[name='colors']");
var btnRestore = $("button[name='restore']");
var btnRemove = $("button[name='remove']");
// Cycle through each option, adding its value and text to our collection
$("option", list).each(function(i, o){
colors.push({ 'key':$(this).val(),'val':$(this).text() });
});
// Remove any remaining options, and add collection back into dropdownlist
$(btnRestore).click(function(){
$("option", list).remove();
for (var i = 0; i < colors.length; i++) {
$("<option>").val(colors[i].key).text(colors[i].val).appendTo(list);
}
});
// Remove first option from list - used to test 'Restore' functionality
$(btnRemove).click(function(){
$("option:first", list).remove();
});
});
I would clone the list of options before modifying it and keep the original around. That way you can reinsert it clean by replacing the modified one with the orignal.
