How do I add dropdown menu to JavaScript template literal

I am trying to add a feature whereby when the user clicks on another user's name a dropdown menu appears with some options. The username is dynamically created using AJAX and template literals. The drop down menu appears to append when I check in dev tools but it doesn't physically appear in the UI. I'm not sure if I am going about it in the right manner. Here is my code:
`
[...]
<div class=card-text">
<p class="venue-text">${venueDescription}</p>
<h6 class="venue-source card-subtitle" id="${source}-adder" data-idtext="${source}-adder">-${source}</h6>
</div>
<div id="o"></div>
</div>
</div>
`);
venueCard.appendTo(myCol);
myCol.appendTo('#venueCard');
document.getElementById(source + "-adder").addEventListener('click', function(e) {
if (e.target && e.target.matches("h6.venue-source")) {
let sourceDropdown = document.getElementById('o');
let dropdown = $(`
<div class="dropdown">
<div class="user-options" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"></div>
<div id="${source}-dropdown" class="venue-card-dropdown dropdown-menu" aria-labelledby="dropdownMenuButton">
<a id="share ${source}" data-idtext="share-${source}" class="dropdown-item" href="#">Share</a>
<a id="add ${source}" data-idtext="${source}" class="dropdown-item add" href="#">Add to List</a>
</div>
</div>
`)
console.log(`dropdown for ${source}`)
dropdown.appendTo(sourceDropdown)
};
});

Pop selection off dropdown menu

I have a question about popping selection from dropdown off the menu. I have a dropdown that gets dynamically populated with people's names, and I'd like the name selected to pop off the drop down menu and appear in a div next to it. The dropdown menu:
<div class="col-md-4">
<div class="dropdown">
<button style="width: 100%;" class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Select Group Members
<span class="caret"></span></button>
<ul class="dropdown-menu scrollable-menu" role="menu">
{{#each users}}
<li data-uid={{this.u_id}}>{{this.full_name}}</li>
{{/each}}
</ul>
</div>
</div>
And the div I'd like the information (name) to appear:
<div class="col-lg-4">
<h2 class="text-center" style="margin-top: 0;">Selected Group Members</h2>
<ul class="list-unstyled">
<li data-uid={{this.u_id}} class="text-center">{{this.full_name}}</li>
</ul>
</div>
I'm imagining this can be done with some jQuery, which I'm unfortunately not too great at, so I'm not quite sure how to do this. Any help is appreciated!

This should does the work. Please check.
// selected element
var selections = [];
// container that holds selections
var listContainer = $('.container .list-unstyled');
// sorting array of objects by provided field
var sortBy = function (arr, field) {
return arr.sort(function (a, b) {
if (a[field].toLowerCase() < b[field].toLowerCase()) return -1;
if (a[field].toLowerCase() > b[field].toLowerCase()) return 1;
return 0;
});
};
// redraw list on container
var reorder = function(){
listContainer.html('');
for(var i = 0; i < selections.length; i++){
listContainer.append('<li data-uid=' + selections.id + '>' + selections.value + '</li>');
}
}
// list items click handler
$('ul.list-unstyled li').click(function(){
selections.push({
id: $(this).attr('data-uid'),
value: $(this).text()
});
selections = sortBy(selections, 'name');
});

AngularJS - How to maintain checked ticket ids of a table

I have a table containing next & previous pages. I am able to navigate to next/previous pages using next & previous buttons.
On previous & next page actions on call(controller methods) I am pushing checked ticket ids by pushing in an array $scope.checkedTicketIds
angular.forEach($scope.tickets, function(ticket) {
if(ticket.checked) {
$scope.checkedTicketIds.push(ticket.id);
}
});
HTML code is
<div class="mail-tools tooltip-demo m-t-md">
<div class="btn-group pull-right">
<button ng-click="previousPage()" ng-disabled="previousPageBtnDisabled()" class="btn btn-white btn-sm"><i class="fa fa-arrow-left"></i></button>
<button ng-click="nextPage()" ng-disabled="nextPageBtnDisabled()" class="btn btn-white btn-sm"><i class="fa fa-arrow-right"></i></button>
</div>
<div class="input-group">
<div class="input-group-btn" dropdown>
<button ng-disabled="ticketsChecked()" class="btn btn-white dropdown-toggle pull-left" dropdown-toggle type="button">{{'ACTIONS' | translate}} <span class="caret"></span></button>
<ul class="dropdown-menu pull-left">
<li ng-repeat="(key, value) in actions"><a ng-click="convertAction(key)">{{key | translate}}</a></li>
</ul>
</div>
</div>
</div>
In controller on clicking previous page button calling method
$scope.previousPage = function() {
angular.forEach($scope.tickets, function(ticket) {
if(ticket.checked) {
$scope.checkedTicketIds.push(ticket.id);
}
});
$scope.ticketsUpdatedQueryCriteria.page = --$scope.page;
Tickets.query($scope.ticketsUpdatedQueryCriteria).then(function(tickets) {
$scope.tickets = tickets.data;
$scope.ticketsPageData = tickets.cursor;
});
};
How to pop/remove id on uncheck & I wanted to maintain checked ticket ids for further bulk actions, like change status of one/more tickets. How can I do this?

I implement an example on jsbin, using an independent checked list.

Hope I help you.

Convert razor enumdropdownlistfor to bootstrap button group dropdown

I have a razor syntax enumdropdownlist for displaying either active/inactive status.
#Html.EnumDropDownListFor(model => model.Status, new { #class = "btn btn-default btn-lg dropdown-toggle" })
I want to use a button group drop down with glyphs like I have below but don't know how to get my model value 'model.Status' to set the value of the button group drop down.
$(document).ready(function() {
$('#item1').on('click', function() {
$('#item0').text('Active');
});
$('#item2').on('click', function() {
$('#item0').text('Not Listed');
});
});
<div class="btn-group">
<button id="item0" type="button" class="btn btn-default">Action</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
<li id="item1">
<span class="glyphicon glyphicon-ok" aria-hidden="true"></span>Active
</li>
<li id="item2">
<span class="glyphicon glyphicon-remove" aria-hidden="true"></span>Not Listed
</li>
</ul>
</div>
I don't care if I use html or razor, I just want to use the boostrap button drop down with glyphs and I want to be able to set the enumerated view model value active/inactive (Status) when the page loads.

Although the Bootstrap dropdown buttons look similar to a select list, their functionality is vastly different. I wouldn't recommend trying to use a Bootstrap dropdown button as a replacement for a select list if you need to actually post the "selected" item.
If you're just looking for a more stylistic and visually appealing alternative to a traditional select control, take a look at something like Select2, and while the look is pleasant enough out of the box, there's also a project that styles it to fit even better with the rest of Bootstrap.
If you're dead set on using Bootstrap dropdown buttons, you've got a lot of work ahead of you. You'll need to set up some JavaScript that will read the information from the select element and dynamically create the Boostrap dropdown button based on that, while hiding the original select. Then, you'll need to map over all the events such as a click on one of the items in the dropdown so that it selects the same item in the actual select element. You'll also have to account for highlighting the item in the dropdown that corresponds with the selected option in the select list, etc. If you run into specific problems while writing all that code, you can ask additional questions here as necessary, but providing you with all the code you'll need here is far beyond the scope of StackOverflow.

You can try to enumerate through enum values and put them in page, please notice the Html.HiddenFor from the end, we will use it to store the selected Status.
<div class="btn-group">
<button id="item0" type="button" class="btn btn-default">Action</button>
<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
<span class="caret"></span>
<span class="sr-only">Toggle Dropdown</span>
</button>
<ul class="dropdown-menu" role="menu">
#{
var values = Enum.GetValues(typeof(Status));
for(int i=0; i < values.Count; i++)
{
var status = (Status)values[i];
<li id="item#(i+1)" class="select-status" data-status="#values[i]">
<span class="glyphicon glyphicon-ok" aria-hidden="true"></span>#status.ToString()
</li>
}
}
</ul>
</div>
#Html.HiddenFor(model => model.Status)
After we create the html we have to update the selected Status in Html.HiddenFor to persist when a POST is performed.
$(document).ready(function() {
$('.select-status').click(function(){
$('#Status').val($(this).data('status')); // update the status in hidden input
});
#for(int i=0; i < values.Count; i++)
{
<text>
$('#item#(i+1)').on('click', function() {
$('#item0').text('#status.ToString()');
});
</text>
}
});
HTML snippet example:
$(document).ready(function() {
$('.select-status').click(function(){
$('#Status').val($(this).data('status')); // update the status in hidden input
});
$('#item1').on('click', function() {
$('#item0').text('Active');
});
$('#item2').on('click', function() {
$('#item0').text('Not Listed');
});
});

</li>
</ul>
</div>
<br />
Visible Status just for test
<input type="text" id="Status" value="1" />
Note: The code may have some errors but the logic/flow is the same.

In .cshtml file
<script>
myModelStatus = '#Model.Status';
</script>
#Html.EnumDropDownListFor(model => model.Status, new { #class = "btn btn-default btn-lg dropdown-toggle" })
more html here...
In your js file
$(document).ready(function() {
var status = myModelStatus;
$('#item1').on('click', function() {
$('#item0').text('Active');
});
$('#item2').on('click', function() {
$('#item0').text('Not Listed');
});
});

You are listening for click events on the li element rather than on the anchor tag
You should stop event propagation by using event.preventDefault() method.

How to update a textfield based on other form elements

I'm writing a little database query app.
What i'm trying to do: Each time a checkbox is clicked, i'd like for a query that includes the selected fields to be generated and inserted into the textarea.
The problem: For some reason, with every click, its showing the query from the previous click event, not the current one.
Here's the markup:
<div class="application container" ng-controller="OQB_Controller">
<!-- top headr -->
<nav class="navbar navbar-default navbar-fixed-top navbar-inverse shadow" role="navigation">
<a class="navbar-brand">
Algebraix Database Client
</a>
<ul class="nav navbar-nav navbar-right">
<!--<li>Clear Queries</li>-->
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
<span class="glyphicon glyphicon-import"></span> Load Data <b class="caret"></b></a>
<ul class="dropdown-menu">
<li>Default Data</li>
<li>Custom Import</li>
<!-- <li class="divider"></li> -->
</ul>
</li>
<li>
<a href="" class="queries-clear">
<span class="glyphicon glyphicon-remove"></span> Clear Queries
</a>
</li>
</ul>
</nav>
<!-- left column -->
<div class="col-md-4">
<div class="well form-group">
<ul>
<li ng-repeat="option in options">
<input type="checkbox" class="included-{{option.included}}" value="{{option.value}}" ng-click="buildQuery()" ng-model="option.included"> {{option.text}}
</li>
</ul>
</div>
</div>
<!-- right column -->
<div class="col-md-8">
<form role="form" id="sparqlForm" method="POST" action="" class="form howblock">
<div class="form-group">
<!--<label>Query</label>-->
<textarea type="text" name="query" class="form-control" rows="10" placeholder="Write your SPARQL query here">{{query}}</textarea>
</div>
<div class="form-group">
<input type="submit" class="btn btn-primary" value="Submit Query" data-loading-text="Running Query..." />
</div>
</form>
</div>
</div>
And in my controller, i am doing the following:
var OQB_Controller = function($scope) {
console.log('OQB_CONTROLLER');
$scope.query = 0;
$scope.options = [
{ text: "checkbox1", value: "xyz123", included: false }
,{ text: "checkbox2", value: "abcRRR", included: false }
,{ text: "checkbox2", value: "abcRRR", included: false }
];
$scope.buildQuery = function() {
console.log('click');
var lines = [];
lines.push("SELECT *");
lines.push("WHERE {");
lines.push(" ?s ?p ?o .");
for(var i = 0; i<$scope.options.length; i++) {
var line = $scope.options[i];
console.log( line.value, line.included, i );
if( line.included ) {
lines.push(" OPTIONAL { ?s "+line.value+" ?o } .");
}
}
lines.push("}");
lines.push("LIMIT 10");
var _query = lines.join("\n");
$scope.query = _query;
};
};
To reiterate, every time the build query method is called, the state of the included booleans is from one click event prior. this has the symptoms of the classic javascript problem of the keyup vs keydown and the state of the event... however, i'm not sure if that is what is happening here.
is there a better way to do build the query (than what i'm currently doing) and populate the textarea based on the checked boxes?

use ng-change instead of ng-click because it is more appropriate for this particular desired behavior. See the ng-change documentation below:
The ngChange expression is only evaluated when a change in the input
value causes a new value to be committed to the model.
It will not be evaluated:
if the value returned from the $parsers transformation pipeline has
not changed if the input has continued to be invalid since the model
will stay null if the model is changed programmatically and not by a
change to the input value
