Remove entire table row having checkbox which was unchecked , when user click on submit button

I have table with checkall/uncheckall check box functionality and table is having and some input fields like text boxes, dropdowns. User should select at least one checkbox for processing the data in the table. That is working fine. For example table is having 3 rows and user select any one checkbox and click on submit button then remaining two table rows should be removed and not being submitted. I tried with the below one .
$("input:not(:checked)").each(function () {
$('input:not(:checked)').closest('tr').remove();
});
But this one is removing entire table. So I need only those table rows which are unchecked should be removed. Any help would be greatly appreaciated.

Assuming you don't use <th></th>, your header row also got selected because that checkbox is also unchecked. May be that will be the reason all rows got deleted. Console input:not:(:checked) it . It will give clear idea.
Edit:
Then try this, may be this will work
$('#tableid').find('tr[input:not:(:checked)]').each(function()
{
$(this).remove();
}

It seems to be working fine for me: https://jsfiddle.net/r9zgvbqu/7/
Two comments, you are using the .each() function to do something for all elements selected by "input:not:(:checked)", but in that function selecting everything again. so you are just doing the same thing multiple times. You can skip that step, and also skip the .each()-$(this) combination that has been suggested, by straightup doing:
$("input:not(:checked)").closest('tr').remove();
This removes all the you want.
EDIT: Your problem is that you are selecting all non-checked inputs, including text inputs etc. You can specify the type of input you are selection: input[type=checkbox]:not(:checked)
In general, I would avoid selecting elements by their tag name. It's better to give the relevant checkboxes a class, and you can select them by class.
Here is a fixed version of your fiddle: https://jsfiddle.net/927sdh8n/
And here is a simpler and safer version using classes: https://jsfiddle.net/qz53wfxc/

Trying to add functionality to select option

In my program the user first enters some data to filter and the result goes to one dropdown select menu lets call this functionality function_1 . If there is only one result the it goes to make another query, lets call this function_2.
My problem here is when i have 2 or more results i should be able to:
1) check out the different options i get by clicking on the select to display all the options with a scrollbar if needed
2) After he saw the options there he clicks on one of them to activate function_2
The usual answers use the "change" event but, wont work if the user picks first default value because there is no change, he would have to pick an undesired result and go back to the first.
Using the click event on the select makes also unnecessary work because it triggers twice (one when i open the dropdown, other when option is selected)
Main problem here i think is the jquery selector, but im not sure if it can be done just with that.
This is an example of what im trying:
// function_1 in ajax
.done(result){
$.each(result.data,function (){
$('#select_ex').append("<option value...... ></option>");
if (result.count()===1){
$('#select_ex').trigger('change');
}
});
}
$('#select_ex option').change(function(){// tried with change, click or focus
function_2();
}
The html contains
<select name="select_ex" id="select_ex" size="0" ></select>
EDIT:
Not related to the duplicate question mentioned, since i already know why it doesnt select the option, besides it doesnt apply either since it only talks about connectors with ID, which is not even the point here (I could do my thing without IDs). Im asking for funcionality similar to ":selected" but with option->click.
Another workaround i thought of is filling the select with an empty/hidden field and set the selected property it, filtering afterwards and using the regular change event... but then the first item would be blank and doesn't seem very logic to me.
So I came to seek for any fresh ideas.
EDIT2
I added a white option for the multiple result and erased it afterwards by adding this line of code to imvain2 solution (where needed)
$("#select_ex option[value='0']").each(function() {$(this).remove();});

Although fixing your change function so that is is called for the select and not the option is important, your problem is the default selected option itself. As you mentioned, if they want the first option, they have to select something else to trigger the change function.
I would recommend adding a "blank" option as the first option and setting it as selected.
var $select_ex = $("#select_ex");
.done(result){
$select_ex.empty().append("<option value='0'>Select Your Ex Below!</option>");
$.each(result.data,function (){
$select_ex.append("<option value...... ></option>");
});
$select_ex.val("0");
}
$select_ex.change(function_2);

How can I show a hidden DIV for a selection included with others?

I have a javascript file that when called, checks to see if a particular option is selected on a form. The form allows for multiple selections before being submitted. When a particular item is selected within the given choices it shows a hidden menu. In this case with "audits" I am able to show the hidden menu fine when just "audits" is selected from the list. However, I'm having much difficulty in figuring out how to get the menu to show when "audits" would be selected/highlighted with others. Eg: I had audits, services, someotheroption
Below you can see the code I'm currently using and that's working only when the single item is selected. Any guidance would be much appreciated.
function toggleFields(){
function toggleFields(){
if ($("#installations").val() == "audits"){
$("#dbcredentialsfield").show();
}
else
$("#dbcredentialsfield").hide();
}

Using the code you have so far, I assume you probably want something like this:
$('#installations').on('change', function(){
$("#dbcredentialsfield").toggle($(this).val() == 'audits');
});
This says; when the select element (assuming your dropdown has the id of installations) changes, toggle the visibility of the element with id dbcredentialsfield depending on if the value of the select is audits or not.

How to change dropdown list label text on click?

I have a <select> element in my HTML that is bound via ng-model to an object in the scope.
Initially I want the dropdown to read "Group..." but when the user clicks on the control I want "Group..." to be renamed to "All" so that "Group..." can never be selected, in the same sense that sites use text boxes with default text that gives you a hint to what the form is for and disappears when it gets user focus (e.g. A "Search..." field).
Here is my JSFiddle example which isn't working as I expected: http://jsfiddle.net/TXPJZ/561/
I figured that ng-onclick="myOptions[0].label = 'All'" would work, it should change the value of the data structure that populates the dropdown and thus change the dropdown options but it doesn't.
How do I make this work like I want?

ng-click is the directive you want, not ng-onclick. Using that it seems to work the way you want it to:

Cannot pass Array elements to restore a form

I am beginner in JavaScript. For exercise, I try to restore a form (at page closed / page reloaded) using cookies. I take the following steps:
Create an array with form selections
Convert to string
Create cookie
Retrieve cookie
Extract string
Convert to array
... Until here everything goes perfect. But the next step doesn't work anymore...
Pass array values to restore the form elements
Regardless the form selections (present correctly in the retrieved array) after reloading page I get every time only last the radio button checked (even if I increase or reduce the number of buttons) and all checkboxes checked.
I tried anything I know to find the error but no success. I also converted the string "true"/"false" values to Boolean, but no change.
The real situation:
frm[0]=true
frm[1]=false // for two radio buttons
frm[2]=false
frm[3]=false // for two checkboxes
document.getElementById("myradio1").checked=frm[0]
document.getElementById("myradio2").checked=frm[1]
document.getElementById("mycheckbox1").checked=frm[2]
document.getElementById("mycheckbox2").checked=frm[3] // pass the array values to the form elements
But, as I said, any values I pass I always get selected the last radio buttons and all checkboxes.
Probably this code doesn't follow the "best practices" of JavaScript, but before I change it I want to understand why it behaves like this. I thank you in advance for your comments, because I want very much to clarify this issue.

It happens because for a radio button, only one radio button can be clicked in a group of radio buttons.
And for the checkboxes, you are using the same ID twice, so the change isn't actually reflecting on the other checkboxes.
