Angular ng-model in appended Html code not working

This is my code. Where I dynamically add html on a button click.but the ng-model which I gave there is not working.
Can anyone solve my issue
$scope.addParam = function(selected) {
if (selected == "bucket_policy_privacy_status") {
var myElement = angular.element(document.querySelector('#inputParameters'));
myElement.append('<input type="text" style="width:220px" class="form-control" name="" disabled="" value=' + selected + '> <select class="form-control" style="width:196px" ng-model="fields.privacyStatus" ><option value="range">Range</option><option value="public">Public</option><option value="private">Private</option></select> <br><br>');
$scope.$watch('fields.privacyStatus', function() {
var privacy_status = $scope.fields.privacyStatus;
alert();
var status = {
"term": {}
}
status.term[selected] = privacy_status;
output.push(status);
});
$('#params option[value="bucket_policy_privacy_status"]').remove();
$scope.input.select = "bucket_owner";
}
};

There are a few things you will need to change:
You need to use Angulars $compile option to evaluate angular attributes/expressions when inserting HTML dynamically.
Adding the line below after you added the element ot the DOM should do the trick:
$compile(angular.element('.form-control'))($scope);
It basically just let's angular know there is something new it should evaluate and start watching.
(Don't forget to add $compile to your module dependencies).
Further to that I assume you have actually added an object called fields on your $scope?
Another thing you could do is use ng-change on your form instead of using $watch. The function you bind on ng-change would be invoked every time one of the selects in your form changes.
For further reading have a look at this:
https://docs.angularjs.org/api/ng/service/$compile

I think that will not work, you are adding only dom, that's all, there's no bind.
One way is to create directive which will do that, or add that input in template with "ng-hidden", and on click just show.

Clearing a div in Jquery using its i.d

I am trying to remove the user input and replace it with the original placeholder by using the empty() function.
Here is the jQuery file which takes input from user through a <form> and appends it to list with the template() structure:
var template = function(text) {
return '<p><input type="checkbox"><i class="glyphicon glyphicon-star"></i><span>' + text + '</span><i class="glyphicon glyphicon-remove"></i></p>';
};
var main = function() {
$('.form').submit(function() {
var text = $('#todo').val();
var html = template(text);
$('.list').append(html);
$('#todo').empty();
return false;
});
};
$(document).ready(main);
After the user submits their text and it is added to the list I want the 'form' input to empty so you can enter a new item with out deleting what you just typed.
Here is a snippet of the html file that jQuery is interacting with:
<form class="form">
<div class="form-container">
<input id="todo" type="text" class="form-input" placeholder="Add item">
</div>
<button type="submit" class="btn">+</button>
</form>
Why is the line
$('#todo').empty();
not removing the user input and returning it to the original placeholder?

The empty method doesn't delete the attributes or values but it removes the html inside an element. You should use val:
$('#todo').val('');//To empty the value
If you want to remove the placeholder too then use removeAttr method:
$('#todo').removeAttr('placeholder');

.empty() is for other use cases. From the docs...
Remove all child nodes of the set of matched elements from the DOM.
Instead, you can .val('') your <input />. Observe the following simplified example...
$('.form').submit(function() {
$('#todo').val('');
return false;
});
JSFiddle Link - demo
as an observation to your neighboring code you can also pass the event and call .preventDefault() in place of return false;. Alternatively, you can call reset() in your function block as such: this.reset() - reset demo with default behavior prevented.

Try this:
$('form').trigger("reset");
This is the most elegant and correct way since it will work when you have multiple and different type of inputs without needing to do any changes. Much better than trying to empty and resetting placehorders on all fields. This will make sure to set the fields to initial state (having placeholders set too).
Based on your code you could do:
$('.form').submit(function() {
// ...
$(this).trigger("reset");
// ...
});
See it working on an example form based on yours with more fields inputs and select here.

CKEditor SetData JQuery

I have a DropDownList where onChange sets the content of the TextArea which is my CKEditor control.
When the editor is not in use I run this bit of code for onChange:
$(".setBody").change(function() {
//
var className = "." + $(this).attr("sExternalId");
var text = $(this).val();
//
$(className).val(text);
});
I'm not very experienced with Javascript/JQuery and I just can't figure out how to perform the same using CKEditor's setData() function. This is what I've tried:
$(".setCKBody").change(function() {
//
var className = "." + $(this).attr("sExternalId");
var text = $(this).val();
//
var editor = $(className).ckeditorGet();
editor.setData(text, function() {
alert("The content was set");
});
});
$(".setCKBody").change(function() {
//
var className = "." + $(this).attr("sExternalId");
var text = $(this).val();
//
CKEDITOR.instances[$(className)].setData(text, function() {
alert("The content was set");
});
});
Am I close? I think one of the main limitations is that I have multiple editor controls with the same id and name, only the class can tell them apart which is why I'm using that with the JQuery. I've tried working through some examples online, but I'm not sure how to apply them to this scenario - that's probably my inexperience coming through there...
Thanks.
EDIT
This is how my textarea and dropdownlist appears in view source:
<textarea class="editArea M3" cols="20" id="Body" name="Body" rows="5">
*some text*
</textarea>
<select class="setCKBody" id="Templates" name="Templates" sExternalId="M3">
<option value="some value">Option 1</option>
<option value="some value">Option 2</option>
</select>
The onChange event above is triggered from the dropDownList changing and is linked to the textArea via the "sExternalId" attribute. I realised I used "id" as the attribute name in the example above which was in error, so I changed that.
I use this to set it as a CKEditor control:
<script>CKEDITOR.replaceAll('editArea');</script>
I have between 2 to 6 textarea controls on the same page, created with razor like this:
#Html.TextAreaFor(m => m.Body, new { #class = "span12 editArea " + Model.ExternalId, rows = 5 })
They are contained within a partial view that is used like this:
#foreach (MailTemplateModel oTemplate in Model.Templates)
{
#Html.Partial("_MailPartial", oTemplate)
}
This is why each text area has "Body" set as the id and name. I think this is the heart of the problem, with there being multiple elements with the same id and name CKEditor is not able to select the correct one. I've tried to do CKEDITOR.instances["className"] but that was undefined, whereas doing CKEDITOR.instances.Body did work, but would only ever return the same value.
I'm going to restructure the way the page is created to avoid this, hopefully my issues will be solved at the same time.

Here's a few pointers.
Use class="foo" if you have many things that you refer to as a group, like like here it looks like you would have many setCKBody elements you listen to for change events.
Use id="foo" if you have one single specific thing.
Using the same id and class for one element usually is not the right thing to do.
CKEDITOR.instances[xxx] <-- xxx should be a string, not a jquery object - so CKEDITOR.instances[className] might work better (I can't say not having seen your HTML).
It would help if we saw your HTML; textarea definitions and setCKBody definitions. Do you have many ckeditors and many setCKBody elements?

My original approach to this scenario was all wrong, I had a model that contained multiple mail templates and so I rendered each one via a partial view within the same page so that the user could click to edit any one of them and the details would appear in a modal popup - within the same window. What I wanted to avoid was forcing the user to navigate to another window to edit a mail template, but this lead to multiple elements having the same id and name attributes which prevented me from accessing them correctly.
I've now added a list box where the user can select a template to edit, the selected template is rendered underneath and so avoids the multiple name and id issue. Now I know there is only ever 1 CKEditor control so I can access it in my js like this:
var editor = CKEDITOR.instances.SelectedTemplate_Body;
SelectedTemplate_Body is the name and id of the element I made into a CKEditor control. The onChange function I wrote for the dropdownlist is now written like this:
$(document).ready(function() {
//
$(".setBody").change(function() {
//
var templateId = $(this).val();
//
$.ajax({
type: "GET",
url: msHost + "MailTemplates/UpdateBody",
data: { "templateId": templateId },
cache: false,
dataType: "text",
success: function (data) {
CKEDITOR.instances.SelectedTemplate_Body.setData(data);
}
})
});
});
The tempalteId attribute is the value associated to the dropdownlist selection, this lets me know which template to use for setting the content of my editor control.
MailTemplates/UpdateBody points to a public method in my MailTemplates controller which runs a search on available mail templates and matches against the template Id passed in, the method then returns the body of the template as a string.
public string UpdateBody(string tempalteId)
{
TemplateQuery oQuery;
//
oQuery = new TemplateQuery();
oQuery.Execute();
foreach (MailTemplate oTemplate in oQuery.Results)
if (oTemplate.Id.Equals(templateId))
return oTemplate.Body;
//
return string.Empty;
}
This line replaces the contents of the CKEditor control with the response from the controller method.
CKEDITOR.instances.SelectedTemplate_Body.setData(data);
Thanks #Nenotlep for trying to help out, you gave me a few things to think about there.

dynamically created form depending on <select> does not work

I'm developing a website which must display particular forms for various products depending on the value that the user selects (in <select>) - so a number various forms are created dynamically in a loop by means of a javascript function (buildform() ). The code does not work, e.g. the forms are not created/appended to the wrappers. I narrowed down the problem where i think the problem relates to a different values for the jquery selectors/div-id's (#ecorpproductwrapper"+ecorp_eprodselectid).
When I use (just as a test) #ecorpproductwrapper" (without the variable ecorp_eprodselectid; see also in code below under ALTERNATIVE WORKS) the code works fine, e.g. the forms are built. I checked by means of the console that the ecorpproductwrapper"+ecorp_eprodselectid values are the same for the div-id's and jquery selectors, so I dont understand what goes wrong?
Pls see the simplified code below:
for(var i=0;i<5;i==){
var ecorp_eprodselectid; //will have various values
//function to build form depending on selected value in <select class= eprodtype"+ecorp_eprodselectid >
$(".eprodtype"+ecorp_eprodselectid).focus(function () {
var previous;
// Store the current value on focus and on change
previous = this.value; //old select value
}).change(function() {
var optionsform = buildform(this.value);
console.log('append form'+optionsform);
//NEXT 2 lines doe NOT WORK
$("#ecorpproductwrapper"+ecorp_eprodselectid).children().remove(); //remove previous form
$("#ecorpproductwrapper"+ecorp_eprodselectid).append(optionsform);
//ALTERNATIVE works: $('#ecorpproductwrapper').children().remove(); //remove previous tariif struct form
//ALTERNATIVE works: $('#ecorpproductwrapper').append(optionsform);
var str = "#ecorpproductwrapper"+ecorp_eprodselectid;
console.log('STRING ECORP PRODUCT APPEND: '+str);
console.log('change eprod val: '+this.value);
previous = this.value;
});//$("").focus(function () {
}//for i
//function to build form
var buildform = function(ecorp_eproductid) {
//some code here
//NEXT LINE does not work:
form += '<td> <div id="ecorpproductwrapper'+ ecorp_eprodselectid+'"> </div> </td> </tr>'; //cell with wrapper for ecorp product info
//ALTERNATIVE WORKS: form += '<td> <div id="ecorpproductwrapper"> </div> </td> </tr>'; //cell with wrapper for ecorp product info
//some code here; returns form
}//function buildform

I think you forgot to add ecorp_eprodselectid in your function.
var buildform = function(ecorp_eprodselectid ) {

Few things we assume concerning given text above:
You know this.value works
console.log shows optionsform have HTML that it should have. Not said in OP but if not, the function does not work. function seems to be missing already var buildform = function(someVar) as noted by buysDB
As I cannot see your code, I would try first clear everything 100% by chaning this:
$("#ecorpproductwrapper"+ecorp_eprodselectid).children().remove();
to:
$("#ecorpproductwrapper"+ecorp_eprodselectid).html("");
Then:
$("#ecorpproductwrapper"+ecorp_eprodselectid).html(optionsform);
No need for append if you have no intention to keep anything in DIV.
If you have text also in (#ecorpproductwrapper"+ecorp_eprodselectid) which is why you use children(), consider selecting the DIV that can be cleared.
If that still does not work, something is left out that needs consideration.

create a pop-up window and display a list of radio buttons using javascript

I'm writing on a js file.
Here is what I've tried so far. (My code is a bit long but here is what I'm trying to do)
var popUpList= $ ('<input type="radio">A<br> <input type="radio">B<br> <input type="radio">C');
var showPopUpButton=$('<button type="button">Select a Letter</button>');
// showPopUpButton is appended to the body
showPopUpButton.click(function() {
alert(popUpList);
});
When I click on showPopUpButton, the alert window shows [object Object], which I guess means that the variable popUpList is empty.
I couldn't find how to do that in javascript.
I also tried with jQuery as suggested here Create a popup with radio box using js
var popUpList= $ ('<input type="radio">A<br> <input type="radio">B<br> <input type="radio">C ');
showPopUpButton.click(function() {
popUpList.dialog();
});
Now, the buttons are displayed but not inside a pop-up window! And they are all superposed.
Any help will be appreciated.
Thanks!

You need to wrap your <input>s in a container element, e.g.: <div>, because dialog() works on a single element.
In your code, you are asking the dialog() function to work on multiple DOM objects and thus it will fail.
Here is the code:
var popUpList = $('<div><input type="radio">A<br><input type="radio">B<br><input type="radio">C</div>');
showPopUpButton.click(function() {
popUpList.dialog();
});
See it in action here. Try it yourself. :)

Changed your inputs to HTML string, parsing as HTML and inserting inside the #dialog element.
var popUpList= '<input type="radio">A<br> <input type="radio">B<br> <input type="radio">C',
dialogHtml = $.parseHTML(popUpList);
showPopUpButton.click(function() {
$( "#dialog" ).html(dialogHtml).dialog();
});
