displaying the input value of txtbox1 to txtbox2

I want: when I enter in the txtbox Enter amount, then I submit the button , the amount I enter in textbox1 which is inputValue it this display in the txtbox which is totAmountPaid
html
<div class="col-md-12">
<label>Enter Amount:</label>
<input type="text" class="form-control" id="inputValue" value="">
</div>
<div class="col-md-12">
<label>Total Amount Paid:</label>
<input type="text" class="form-control"
readonly="readonly"id="totAmountPaid" value="">
</div>
<div class="col-md-12 ">
</br><button class="btn btn-primary col-md-6" type="button"
onclick="myFunction()" >btn</button>
</div>
script
function myFunction(){
var paidAmount = parseFloat(document.getElementById("inputValue").value);
document.getElementById("totAmountPaid").value = paidAmount.toFixed(2);
}

Are you including your JS before you are trying add the onClick handler?
If you load the js beforehand it should work fine.
As you can see here https://jsfiddle.net/Lyspxwvu/1/
<script>
function myFunction(){
var paidAmount = parseFloat(document.getEle`enter code here`mentById("inputValue").v`enter code here`alue);
document.getElementById("totAmountPaid").value = paidAmount.toFixed(2);
}
</script>
<div class="col-md-12">
<label>Total Amount Paid:</label>
<input type="text" class="form-control"
readonly="readonly"id="totAmountPaid" value="">
</div>
<div class="col-md-12 ">
</br><button class="btn btn-primary col-md-6" type="button"
onclick="myFunction()" >btn</button>
</div>

Try with closest() function and trim() will help remove the unwanted space
$(".form-control").keyup(function() {
if ($(this).val().trim()) {
$(this).closest('.form-group').find(".btn.btn-default").show();
} else {
$(this).closest('.form-group').find(".btn.btn-default").hide();
}
})
.btn.btn-default {
display: none;

getting input from button not working

Below is my html code for the form
<form id="taxi_distance_input" >
<div class="col-md-8" style="display: inline-block; left:-30px">
<div class="col-md-4">
<div class="input-group">
<input type="text" class="form-control" id="usr"> </input>
<span class="input-group-addon" style="width: 50px">km</span>
</div>
</div>
<div class="col-md-4" style="padding-left:0px; margin-left:-10px">
<input type="button" class="btn btn-success" value="Submit" id="myButton"> </input>
</div>
</div>
<p> </p>
</form>
And in the bottom of the page I give the
<script src="/js/form_input_parameter.js"></script>
Inside the form_input_parameter.js i have written the script
$(document).ready(function(){
$('#myButton').click(function(){
var text = $("#usr").val();
alert(text+"success");
});
But it is not working .Any help is apprecited

You've forgotten the }); at the end of your JS code
The input tag should end with />
$(document).ready(function() {
$('#myButton').click(function() {
var text = $("#usr").val();
alert(text + " success");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" class="form-control" id="usr" />
<input type="button" class="btn btn-success" value="Submit" id="myButton" />

AngularJS 1 form validation in the loop

i have a problem with angulare code. I have made a small form structure with ng reapet . When i removed one of element every element down of them are not show the "not valid" message . All up of them work fine but down of remove not showing info not given the false of this data-ng-show="Zhf.w{{key}}.$error.pattern" why ng show not taked false.
<form name="zhf" class="form-horizontal">
<div data-ng-repeat="(key, i) in vm.items.Info | limitTo: (vm.NumberOfDays)">
<div class="col-sm-3">
<input type="text" class="form-control" id="w{{key}}" name="w{{key}}" ng-model="vm.item[key].w" placeholder="0" ng-pattern="/^[0-9]{1,10}([,.][0-9]{1,2})?$/" required>
<p style="color: #a94442" class="text-danger" data-ng-show="Zhf.w{{key}}.$error.pattern">
<span>Not a valid number!</span>
</p>
</div>
<div class="col-sm-2">
<button type="button" class="btn btn-danger btn-sm " ng-click="vm.delete(key)">remove</button>
</div>
</div>
</form>
vm.delete = function(index) {
vm.items.Info.splice(index, 1);
vm.item.splice(index, 1);
vm.NumberOfDays -= 1;
}

I have updated your ng-repeat section to validate form and sample is HERE
<form novalidate="novalidate" name="inputValidate">
<div ng-repeat="field in fields.test">
<div style="width:600px">
<div ng-form name="validMe" style="width:58%;float:left">
<input id="input{{$index}}" name="input{{$index}}" type="text" ng-model="field.value" ng-pattern="/^[0-9]{1,10}([,.][0-9]{1,2})?$/" required>
<span style="color: #a94442" ng-show="validMe['input\{\{$index\}\}'].$error.pattern">Not a valid number!</span>
<span style="color: #a94442" ng-show="validMe['input\{\{$index\}\}'].$error.required ">Number Required!</span>
</div>
<div style="width:20%;float:left">
<input type="button" value="Remove" ng-click="delete($index)"/>
</div>
</div>
</div>
</form>

Checkboxes weird behaviour in AngularJS ng-repeat

I've a form containing input fields and checkboxes (table crud generating dynamically). See the image below:
Here, In my clients modal dialog form I've implemented small crud for adding/updating/deleting Providers data and showing table below of it on the fly.
Following is my code:
View:
<form name="clientForm" ng-submit="check(id)" ng-controller="ClientsController">
<div class="form-group">
<label for="name">Name</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon1"><i class="glyphicon glyphicon-hand-right"></i></span>
<input type="text" class="form-control" id="title" placeholder="Enter Name" ng-model="client.name">
</div>
</div>
<div class="form-group">
<label for="email">Email</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon1"><i class="glyphicon glyphicon-envelope"></i></span>
<input type="text" class="form-control" id="title" placeholder="Enter Email" ng-model="client.email">
</div>
</div>
<div class="form-group">
<label for="phone">Phone</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon1"><i class="glyphicon glyphicon-earphone"></i></span>
<input type="text" class="form-control" id="title" placeholder="Enter Phone" ng-model="client.phone">
</div>
</div>
<div class="form-group">
<label for="phone">Providers</label>
<div class="input-group">
<span class="input-group-addon" id="basic-addon1"><i class="glyphicon glyphicon-hand-right"></i></span>
<input type="text" class="form-control" id="title" ng-model="provider.provider_name" placeholder="Enter Provider Name">
</div>
<br>
<button type="button" id="addbtn" class="btn btn-sm btn-primary" ng-click="addProvider()">Add Provider</button>
<button type="button" id="editbtn" class="btn btn-sm btn-info" ng-click="updateProvider(id)">Update Provider</button>
<button type="button" id="editbtn" class="btn btn-sm btn-default" ng-click="clearProvider()">Clear Provider</button>
<br>
<table style="width: 50%; margin-top: 10px;" class="">
<tbody>
<tr ng-repeat="val in providersData">
<td>
<input type="checkbox" name="providersData" ng-model="$parent.client.providersList" value="{{val._id}}"/>
</td>
<td>{{val.provider_name}}</td>
<td>
<a style="color: blue;" href="javascript:void(0);" ng-click="editProvider(val._id)"><i class="glyphicon glyphicon-edit"></i></a>
<a style="color: red;" href="javascript:void(0);" title="Delete" confirmed-click="removeProvider(val._id)" ng-confirm-click="Are you sure you want to remove provider?"><i class="glyphicon glyphicon-trash"></i></a>
</td>
</tr>
</tbody>
</table>
</div>
<div class="well well-lg text-center bg-gray">
<button class="btn btn-success" ng-if="id">Save Client</button>
<button class="btn btn-danger" ng-if="id" title="Delete" confirmed-click="remove(client._id)" ng-confirm-click="Are you sure you want to remove?">Delete</button>
<button type="button" class="btn btn-warning" data-dismiss="modal" aria-hidden="true">Cancel</button>
<button class="btn btn-success" ng-if="!id">Add Client</button>
</div>
</form>
Controller:
$scope.showModal = false;
$scope.client = {};
$scope.provider = null;
$scope.addClient = function () {
alert(JSON.stringify($scope.client));
$http.post('/clients', {param: $scope.client}).success(function (response) {
if (response) {
alert("Client added successfully");
$scope.client = "";
refresh();
$scope.closemodal();
}
});
};
Now I want to insert/update selected checkboxes value to db along with Name, Email, and Phone field.
Here I'm facing following issues:
Whenever I'm clicking on any checkbox its checking all checkboxes.
After clicking on Add Client button its showing result of alert(JSON.stringify($scope.client)) like this
{"name":"asdfdsafasdf","email":"sdf","phone":"sadf","providersList":{"id":true}}
In mongodb its showing like this:
I've search a lot tried this and ng-model="$parent.client.providersList.id" but still its not working.
I'm beginner in AngularJS and just started working on it.
Any help would be appreciated.

You should use ng-true-value & ng-false-value over the checkbox(I'm considering default value to be 0). And then use $index of providersData ng-repeat to create an array of client.providersList.
Markup
<input type="checkbox" name="{{'providersData'+$index}}"
ng-model="client.providersList[$index].id" ng-true-value="val._id" ng-false-value="0" />

You are facing this problem because of the value of your ng-model attribute. The value for ng-model attribute must be different for each checkbox. Here, try this:
<input type="checkbox" name="providersData" ng-model="client.providersList{{$index}}" ng-value="val._id" />
Try something like this:
$scope.client = {};
$scope.client.providersList = [];
// Now watch the model for changes
$scope.$watch('client', function(){
// When the checkbox is selected it returns true
if($scope.client.providersList1 == true){
$scope.client.providersList.push({"id": value})
}
// Repeat the if statements for all the checkboxes (or use a for loop)
}, true);
