Problem loading JS when creating and modifying an element

I hope you can help me with these problems that I have with the execution of my JS, I have 2 problems that I will detail:
WHEN CREATING
I am using the change and select events to be able to know if I am selecting and changing an option from my question combobox. The problem is when I have selected the option 1 SINGLE / MULIPLE ANSWER of the question type. If when saving I do not have any checkbox selected from the available options, it will throw me the alert to select at least one option, so far everything works fine for me but when I select a checkbox from the options and try to save, the alert does not disappear. I've tried adding the event checked but it can't work for me. What I want to do is that when I save and I do not have an option selected, it throws me the alert message (this already does), and when I select an option, the alert disappears so that it allows me to save.
WHEN MODIFYING
The second problem occurs when I try to modify an element, the JS does not run, so that it can work I have to select another option and return to the previous one so that it can work.

Hope you can help me with these problems, I am not very good at using javascript or jquery. I thank you in advance for your support.

In your current code you are using wrong selector to get total value of checked checkboxes.If you check your current jquery code its always giving 0 even if you checked any value. So , you can use input[type="checkbox"]:checked which will give you correct values of checked checkboxes.
Then , you have placed your submit event inside your change event that's the reason the warning shows for the first time but when you select some checkbox and again clicked save button it doesn't go away (also because of wrong selector) so i have separated it from the change event .
Also you have forget to show the tr which you have hide() when select-box value is 2 i.e : item-option so add .show() to it when value is 1.
Working Code :
$(".dynamicform_wrapper").on("change", "select", function() {
if ($(this).val() == 2) {
$('#0').find('.option-item').not(':first').remove(); //removed all entries found in
$('#0').find('.option-item:first').hide();
$('#0').find('.item-option').hide();
$('#0').find('.question').attr('colspan', 2);
} else if ($(this).val() == 1) {
// $('#0').find('.container-options').append(newtr); //add input
$('#0').find('.item-option').show();
$('#0').find('.option-item:first').show(); //show option-item which is hidden
$('#0').find('.question').removeAttr('colspan', 2);
}
});
$("#dynamic-form").submit(function(event) {
//getting all inputs which is under tr
var numberChecked = $('#0').find('input[type="checkbox"]:checked').length;
console.log("No of checkbox checked=" + numberChecked)
if (numberChecked > 0) {
$('#0').find('.text-error-check').hide();
$('#0').find('.dynamicform_inner').removeAttr("style");
event.preventDefault();//remove this to submit
} else {
$('#0').find('.text-error-check').show();
$('#0').find('.dynamicform_inner').css({
'border': '2px solid #dd4b39',
'background-color': 'white'
});
event.preventDefault();
}
});

AngularJS Show just filtered Items in table with ng-repeat

Is possible to hide the result of this table and just show the filtered result?
<table class="table table-responsive"
ng-class="{'table-striped':!spinnerVisible}">
<thead class="thead-inverse">
<tr>
<th><input type="checkbox" value="selected"
ng-model="checkboxes.checkAll"
ng-click="checkAllRows()"></th>
<th>SID</th>
<th>Name</th>
<th>Pathway</th>
<th>Advisor</th>
<th>Credits</th>
<th>Campus</th>
<th ng-if="isPathwayLead">Action</th>
</tr>
</thead>
<tr ng-repeat="s in searchData.students
|orderBy:'lastName'
|filter:search
|range:selectedPage:pageSize"
student-row>
</tr>
</table>
By default the page load a list of students like this
[![enter image description here][1]][1]
I would like to hide this list and just show the result of the filter above!
is that possible?

Basically just want to know if i can use ng-Show just to show filtered results and hide the rest without having to changes a lot of everything

I am sharing the way I normally do where there's a need for searching among the grid list. I normally, take one input as a search term and search the entire list with the help of $filter in my watcher and if it matches with any key of the particular object, update the grid list instantly with the new filtered list.
I don't recommend copy pasting the code since I am using many custom directives and material design. But you can get the main idea how can you do it.
<md-toolbar style="background-color:#F57C00 !important;"
ng-show="showSearch">
<div class="md-toolbar-tools">
<md-input-container class="md-block" flex-gt-sm>
<md-icon style="color:white">search</md-icon>
<input type="text" ng-model="searchPhrase" style="color:white" name="searchPhrase">
</md-input-container>
<md-button ng-click="resetFilter()" class="md-icon-button">
<md-tooltip style="background-color:lightgray;color:black" md-direction="top">close</md-tooltip>
<md-icon>close</md-icon>
</md-button>
</div>
</md-toolbar>
in my controller I write the watcher as :
$scope.$watch('searchPhrase', function (keyword) {
if (keyword!= null && keyword!= '' && keyword!= undefined)
$scope.gridList = ($filter('filter')($scope.actualGridList, keyword));
// incase keyword was empty, change the list back to original
else
$scope.gridList = angular.copy($scope.actualGridList);
});
//incase reset button was pressed, change the list back to original
$scope.resetFilter = function () {
$scope.showSearch = false;
$scope.searchPhrase = '';
$scope.gridList = angular.copy($scope.actualGridList);
}
Note that:
I am using gridlist as the ng-repeat list and not the actualGridList, in this way I will have the original list unmodified and gridList will be reflected back to what the original list is through my resetFilter()
If you want to filter the searchData.students based on many keywords, you can filter the list based on those keys, something similar to:
$scope.copStudents = $filter('filter')($scope.searchData.students,
{ 'name': keyword }, true);

Below is my jquery code where i am looping the html table and want to highlight the input field which is in html table td.
$(document).ready(function() {
$('#rootwizard').bootstrapWizard({
onTabShow: function(tab, navigation, index) {
if (index == 1) {
$('#tblPurchaseOrders').find('tr:has(td)').each(function() {
if (parseInt(($(this).find('#Quantity')).val()) == 0)
{
//show error
}
});
}
}
});
});

You are filtering per ID (#Quantity). Two (or more) elements cannot share the same ID. Try to select elements by name, for example:
$('#tblPurchaseOrders').find('td > input[name=Quantity]').each(function() {
var val = $(this).val();
if (parseInt(val) == 0)
{
// show error
// note: if needed, you can obtain a reference
// to container <tr> using: $(this).parent('tr');
}
});
Remember to change id property of Quantity elements to name.
Note: untested code that might not work as-is, I'm just showing you the right direction.

If your intention is to use the Twitter Bootstrap Wizard (TBW from now on) for your validation flow, you probably don't want this validation to trigger when you open the tab, which is what happens, when you place your code inside of the onTabShow function.
I assume you want the validation of the fields to be done when the user wants to go to the next step, by pressing the "Next" link you have, or rather, when you want to load the "next tab". For this, you should use onNext rather than onTabShow for your validation.
$(document).ready(function() {
$('#rootwizard').bootstrapWizard({
tabClass: 'nav nav-pills',
onNext: function(tab, navigation, index) {
var res = $("input[name='Quantity']").each(function() {
var val = $(this).val();
if(parseInt(val) == 0) {
$(this).focus();
// This will stop the .each-iteration
// We only want to focus the _first_ element, otherwise it
// would keep iterating, and change focus to the next 0-valued input
return false;
}
});
// We use the result returned from running the each function
// If false was returned at any point during the .each function,
// var res will be false. Pass this onto the onNext call, to
// prevent the the user to move to next tab.
if(!res) return false;
}
});
});
For this to work, you'll have to replace id="Quantity" with name="Quantity", in both your instances.
If you want to use .focus() on the first element, regardless of which input is invalid, you should remove $(this).focus() from the previous example, and instead replace if(!res) return false with the following:

How to get input value based on option value selected?

I have a dynamic input form like this (open the link): this is the
form
The option value is "Debit" and "Kredit".
In my case, I wanna get the Jumlah's value based on the option selected. As you can see in that picture, in first row, I input the Jumlah's value with 10 and then I select the "Debit", so the Total Debit value will change to 10 and Total Kredit value still 0.
And then, in the next row, I input the Jumlah's value with 3 and then I select "Kredit", so the Total Debit value still 10 and Total Kredit change to 3.
Then, when I change the second row to Debit, the Total Debit should be 13 and Total Kredit is 0. But, it makes Total Debit to 13 and Total Kredit still 3.
So, how can I solve this? Any suggestions or another alternatives?
Here is my form's code:
<form action="" method="post">
{{ csrf_field() }}
<div class="form-group">
<label for="nojurnal">Nomor Jurnal:</label>
<input type="text" class="form-control" id="nojurnal" value="{{ $noJurnal+1 }}" name="no_jurnal" readonly>
</div>
<div class="form-group">
<label for="tgljurnal">Tanggal Jurnal:</label>
<input type="date" class="form-control" id="tgljurnal" name="tgl_jurnal">
</div>
<div class="form-group">
<label for="keterangan">Keterangan:</label>
<textarea name="keterangan_jurnal" id="keterangan" class="form-control" rows="8" cols="80"></textarea>
</div>

</div>
<input type="submit" class="btn btn-success" value="Simpan">
</form>
And this is my javascript code:
$(document).on('change', '.jenisRekening', function(e){
if ($(this).val()=='D' && $(this).parent().parent().prev().find('.jumlahDK').val() !==''){
totalDebit += parseInt($(this).parent().parent().prev().find('.jumlahDK').val())
}
else if($(this).val()=='K' && $(this).parent().parent().prev().find('.jumlahDK').val() !==''){
totalKredit += parseInt($(this).parent().parent().prev().find('.jumlahDK').val())
}
$('#jumlah-debit').val(totalDebit)
$('#jumlah-kredit').val(totalKredit)
});

The variables totalDebit and totalCredit should be reinitialised to zero in your jQuery code before they're recomputed. It seems that their old value is retained and therefore a simple solution would be:
$(document).on('change', '.jenisRekening', function(e){
totalDebit = 0;
totalKredit = 0;
if ($(this).val()=='D' && $(this).parent().parent().prev().find('.jumlahDK').val() !==''){
totalDebit += parseInt($(this).parent().parent().prev().find('.jumlahDK').val());
}
else if($(this).val()=='K' && $(this).parent().parent().prev().find('.jumlahDK').val() !==''){
totalKredit += parseInt($(this).parent().parent().prev().find('.jumlahDK').val());
}
$('#jumlah-debit').val(totalDebit);
$('#jumlah-kredit').val(totalKredit);
});

Here i just want to add a row to the table. But this time the default values will be there in the row and user will edit it. How can i add a row using jquery without writing the all <td>s in the <tr> in the append method?? Is there any simple way to just copy a row and use default value and add after the last row in the table??

Using EJS and jQuery the most practical way is to store a local variable called default_row. which will contains all td inside of this default row (tr). Like.
var default_row = "<tr> <td> ... <\td> <\tr>"
Finally you can use any append function from jQuery. I suggest you last().
Ps. You should use angular framework. This simple task become easy in angularjs.

I have used canJs. It's very much easy using canJs. At first i seperated out the row part in another ejs and then store it in a variable by below code:
var rowItem = can.view.render("templates/attr-tab-row.ejs",{});
And then added with the table body.
var table_body = $(el).closest('div').find('tbody');
table_body.append(rowItem);
