I've been using this custom Bootstrap select plugin BSMultiselect. I need to select some options after the page has already been loaded, using jQuery/Javascript.
The API documentation is not very clear how to do this. What I've tried is:
var bsMultiSelect = $('#facilityFilter').BsMultiSelect();
bsMultiSelect.updateOptionSelected(0);
This effectively does nothing.
In order to select an option you need for the first set the selected attribute before you update the bsMultiSelect.
The snippet:
$(function () {
var $multiSelects = $("select[multiple='multiple']");
$multiSelects.bsMultiSelect();
// set the selected attribute...
$multiSelects.find('option').eq(0).prop('selected', 'selected');
// ....so, update the bsMultiSelect
$multiSelects.data('DashboardCode.BsMultiSelect').updateOptionSelected(0);
});
.row {
background: #f8f9fa;
margin-top: 20px;
}
.col {
border: solid 1px #6c757d;
padding: 10px;
}

I tried to detect if the clicked element is select2 and perform additional action as required not just opening dropdown list. But it is not successful as I clicked on select2 element nothing happened.
$(document).ready(function() {
$('select').select2();
$('body').on('click', function(e) {
if ($(this).data('select2')) {
console.log('select2 element was just clicked');
} else {
console.log('you are not clicking on select2');
}
});

I don't know why select2 does not receive clicked event. Is there any workaround solution archive this because I need to do more action when select2 was clicked? Thanks so much.
How about something like this?
here's another example: https://jsfiddle.net/f8q2by55/ http://jsfiddle.net/6jaodjzq/
as stated in this answer: Attach click-event to element in .select2-result
Because Select2 lib prevents any click events on popover list you can't bind events to .info directly. But you can redefine onSelect method and place there any code you want.
$(document).ready(function() {
let selector = $('#select').select2()
selector.onSelect = (function(fn) {
return function(data, options) {
console.log('selected');
}
})(selector.onSelect);
})

I'm trying to re-create the most basic "states" select2 example, but it does not match beyond the first letter - just like a normal select element. It does seem to be loading select2, for example, it displays the selected value to the right of the select element. However, when I try to type a state, it only seems to match the first character. I.e., If I type "t" it will match "Texas", but typing "dak" will match "Delaware" rather than "North Dakota".
I've create a gist of my complete html page. I copied the select element directly from the example page, so there's not a whole lot to it.
In a nutshell, I create a select element with the class js-example-basic-single, and then I call select2() on that element.
<script type="text/javascript">
$(document).ready(function() {
$(".js-example-basic-single").select2();
});
</script>
Edit: On JS Bin
Updated jsBin.
Check the simple working snippet below based on you gist code, and make sure you're adding the CSS link include :
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet"/>
Hope this helps.
$(document).ready(function() {
$(".js-example-basic-single").select2({width:'100%'});
});

I am working with the Semantic UI searchable dropdown, which if you're not familiar with it, it can be found here: http://semantic-ui.com/modules/dropdown.html#search-selection.
How would I make it so that once an item is selected in the dropdown, that when you click out and click back in, it would show the currently selected item at the top of the list? So scroll to the selected/active item?
What version of Semantic UI you're using? 'Cause the default behavior of Semantic UI search selection dropdown is just fine.
$('.ui.search.dropdown').dropdown();

Hello!
I am coding a new HTML form that will collect upon many more items a state abbreviation (i.e. "ks"). Right now I have the -input field- limited so it only allows 2 characters. That doesn't keep visitors from entering something random into the field like "SS".
I am wanting a code that allows me to limit what can be placed in that field to only USA's official state abbreviations.
I am using HTML, CSS, and Javascript so far in my website. Thank you for all your help and ideas!!
Update. Added all states, uppercase handling and jsfiddle link.
Here is a pure javascript implementation, should give you an idea of what you need to do:
<script>
function validateState(el) {
//put all states in this array.
var states = ["AK","AL","AR","AS","AZ","CA","CO","CT","DC","DE",
"FL","GA","GU","HI","IA",
"ID","IL","IN","KS","KY","LA","MA","MD","ME","MH","MI","MN","MO","MS","MT",
"NC","ND","NE","NH","NJ","NM","NV","NY","OH","OK","OR","PA","PR","PW","RI",
"SC","SD","TN","TX","UT","VA","VI","VT","WA","WI","WV","WY"];
for(var i=0;i< states.length;i++) {
if(el.value.toUpperCase() == states[i]) {
return true;
}
}
//clear element if it doesn't match a state
el.value = ""; //you could maybe do something else here.
return false;
}
</script>
<input class="up" type="text" maxlength="2" onchange="validateState(this);"/>
See it working live here : http://jsfiddle.net/k7QQs/
You could use a <select> html element.
<select>
<option value="MA">MA<option>
....
</select>
I think this would help.
It has:
mustMatch:true,
You can do it without a script:
<select name="state">
<option value="" selected>Please Select</option>
<option value="AK">Alaska</option>
<option value="AL">Alabama</option>
<option value="AR">Arkansas</option>
<option value="AS">American Samoa</option>
<option value="AZ">Arizona</option>
<option value="CA">California</option>
<option value="CO">Colorada</option>
<option value="CT">Conneticut</option>

That method is easier on your users than expecting them to know a State abbreviation.
Or-
function validState(state){
return state.toUpperCase() in{
AL:1, AK:1, AZ:1,
AR:1, CA:1, CO:1, CT:1,
DE:1, DC:1, FL:1, GA:1,
HI:1, ID:1, IL:1, IN:1, IA:1,
KS:1, KY:1, LA:1, ME:1, MD:1,
MA:1, MI:1,
MN:1, MS:1, MO:1, MT:1, NE:1,
NV:1, NH:1, NJ:1, NM:1,
NY:1, NC:1, ND:1,
OH:1, OK:1, OR:1, PA:1,
RI:1, SC:1, SD:1, TN:1, TX:1,
UT:1, VT:1, VA:1, WA:1,
WV:1, WI:1, WY:1
}
}
