How can I add loading ONLY to the clicked button in vuejs?

There is a table which loops and outputs the data which comes from API. I have added a button inside the table. When you click it, it should send the id of the clicked button and till it recieves the data of the function which needs to be printed, it should be in loading. Here is my code.
<table id="customers">
<tr>
<th>{{$t('message.numberReport')}}</th>
<th>{{$t('message.periodFrom')}}</th>
<th>{{$t('message.periodTo')}}</th>
<th>{{$t('message.printButton')}}</th>
</tr>
<tr v-for="(item,index) in getReportInfo" :key="index">
<td>{{ item.id }}</td>
<td>{{ item.periodFrom }}</td>
<td>{{ item.periodTo }}</td>
<td>
<v-btn
class="primary"
:loading="loading"
:disabled="loading"
#click="fetchGetReportDetailed(item)"
>{{ $t('message.printButton')}}</v-btn>
</td>
</tr>
</table>
But when I clicked the particular button, all the buttons are getting in loaded mode. How do I fix it? Any suggestion would be deeply appreciated.here is the visual example

Using index of item in list.
You can register a new variable in your data for example indexClicked .
data () {
return {
// Some predefined value, 0 isn't good because index can be 0.
indexClicked: undefined // Some predefined value
}
}
And when you click at button you can send index value:
<td>
<v-btn class="primary"
:loading="loading && indexClicked === index"
:disabled="loading && indexClicked === index"
#click="fetchGetReportDetailed(item, index)">
{{ $t('message.printButton') }}
</v-btn>
</td>
And in your fetchGetReportDetailed(item, index) method you need to assign index to this.indexClicked like:
fetchGetReportDetailed (item, index) {
// Your code
this.indexClicked = index;
}
This should work. But if you need more information please provide more code.
Note if you have a problem with multiple conditions in :disable you can create a method which will return true or false depends on condition loading && this.indexClicked === index.
Good luck!

You're using a single data property for all rows, so in mounted hook add a property called loading to each row like :
mounted(){
this.getReportInfo=this.getReportInfo.map(rep=>{
rep.loading=false;
return rep;
});
}
and the template do:
<tr v-for="(item,index) in getReportInfo" :key="index">
<td>{{ item.id }}</td>
<td>{{ item.periodFrom }}</td>
<td>{{ item.periodTo }}</td>
<td><v-btn class="primary" :loading="item.loading" :disabled="loading" #click="fetchGetReportDetailed(item,index)" >{{ $t('message.printButton')}}</v-btn></td>
</tr>
in fetchGetReportDetailed method :
fetchGetReportDetailed(item,index){
....
this.getReportInfo[index].loading=true;
this.$set(this.getReportInfo,index,this.getReportInfo[index])
}

You could separate the tr that is displaying the data into its own state-full component and call the function from within the component.
This way the state of loading for each item in the array will be local to its own component.

how to get the result of two controller on ng-repeat

I want to get the values of the two object in thesame ng-repeat
$http.get('/api/PreviewPayroll').success(function (data){
//alert(data[0].empID);
$scope.allowance = data;
});
$http.get('/api/Deduction').success(function (data){
//alert(data[0].empID);
$scope.Deduction = data;
});
<tr ng-repeat="item in allowance && ng-repeat="value in Deduction">
<td>{{ item.empID }}</td>
<td>{{ value.empID }}</td>
</tr>
how can I get the two scope object on thesame ng-repeat

So you will want to combine the data.
You can use $q.all(promises):
var promise1 = $http.get('/api/PreviewPayroll');
var promise2 = $http.get('/api/Deduction');
$q.all([promise1, promise2]).then(function (results) {
var allowances = results[0];
var deductions = results[1];
var combinedList = /* some combination logic */;
});
By using $q.all() you are ensuring you have both lists of data before trying to combine anything. You can easily play around with this to get the desired effect. For example, if you don't care if the other list isn't available.
Then you can use the ng-repeat in order to iterate over that new combined list:
<tr ng-repeat="item in combinedList">
<td>{{ item.allowance.empID }}</td>
<td>{{ item.deduction.empID }}</td>
</tr>
The sub properties allowance and deduction are based on your combined list.
However
It is in my honest opinion that, the server side gives you the data in the format you need to display it in. (i.e. the business logic remains server side in a controlled environment). I believe the view should only deal with view logic, like button actions etc..
But this is my opinion, and is what I find easiest.
Another note
I prefer to also keep the view logic in the JavaScript, hence why I combine the data there. Rather than trying to do some overly complicated angular expression in the HTML.

You could either have a nested ng-repeat and also combine the two objects into one.
<table>
<tbody ng-repeat="row in mainCombinedObject">
<tr>
<th>{{row.empID}}</th>
</tr>
<tr ng-repeat="sub in row.subObject">
<td>{{sub.empID}}</td>
</tr>
</tbody>
</table>

Combine $scope.allowance and $scope.Deduction to one list of objects "combined" then do your ng-repeat:
<tr ng-repeat="c in combined">
<td>{{ c.someField }}</td>
<td>{{ c.someOtherField }}</td>
</tr>

You can't do that in such way! If your allowance and Deduction have the same size you have to mix them in the collection like this:
var array = [
{ allowance: value1, Deduction: value2},
{ allowance: value3, Deduction: value4},
...
];
and them use it in the view:
<tr ng-repeat="item in array">
<td>{{ item.allowance.empID }}</td>
<td>{{ item.Deduction.empID }}</td>
</tr>

Angular paging generates wrong number of pages

I am having a hard time getting the Angular paging to work correctly. The number of pages seems to be off. For example, for one of my searches, the number of returned results is 1005. Displaying 16 results per page, should have 63 pages total. Instead it generates 101. I appreciate any suggestions on why this is happening and how to resolve.
Thanks in advance!
<table class="table table-striped results">
<thead>
<tr>
<th ng-repeat="x in json.headers">{{ x }}</th>
</tr>
<thead>
<tbody>
<tr ng-repeat="x in filteredResults">
<td>{{ x.name }}</td>
<td>{{ x.city }}</td>
<td>{{ x.state }}</td>
<td>{{ x.zip }}</td>
<td>{{ x.phone }}</td>
</tr>
</tbody>
</ul>
</table>
<pagination
style="position:absolute; bottom:10px;"
ng-show="json.results.length"
ng-model="currentPage"
total-items="json.results.length"
max-size="maxSize"
boundary-links="true"
next-text=">"
last-text=">>"
previous-text="<"
first-text="<<">
</pagination>
JavaScript
var app = angular.module('myApp', ['ui.bootstrap']);
app.controller('formCtrl', function($scope, $http){
$(document).ready(function(){
$('.submit-search').click(function(){
$http.get('model/search_url.php', {
params: { searchBy: $scope.user.searchBy, search: $scope.user.search }
}).success(function (response){
$scope.json = response;
$scope.filteredResults = [];
$scope.currentPage = 1
$scope.numPerPage = 16
$scope.maxSize = 5;
$scope.$watch("currentPage + numPerPage", function() {
var begin = (($scope.currentPage - 1) * $scope.numPerPage);
var end = begin + $scope.numPerPage;
$scope.filteredResults = $scope.json.results.slice(begin, end);
});
});
});
});

You're missing the items-per-page, in your case it should be 16, but since you don't provide it it set to the default of 10 items per page.

Go to URL with ID onClick() Using Laravel

I am building a simple contact database with Laravel and a MySQL database. I have a basic HTML file with a data table that list a series of records. I would like to make it so that when I click on a row, I go to a page based on the ID number of the record in the row clicked.
I have the table populated using a #foreach loop as such:
<tbody>
#foreach ($people as $person)
<tr>
<td>
<a>{!! link_to_action('ContactController#show', $person->id, $person->id) !!}</a>
</td>
<td>{{ $person->name_first }}</td>
<td>{{ $person->name_middle }}</td>
<td>{{ $person->name_last }}</td>
</tr>
#endforeach
</tbody>
The controller (ContactController) shows this:
public function show($id)
{
$person = Contact::findOrFail($id);
return view('contacts.show', compact('person'));
}
Now, I have a JavaScript script on the page:
<script type="text/javascript">
$(document).ready(function() {
$('#contacts').dataTable();
$('#contacts tbody').on('click', 'tr', function () {
var name = $('td', this).eq(1).text();
alert( 'You clicked on '+name+'\'s row' );
window.location="";
} );
} );
</script>
I assume I only need to insert the proper link in:
window.location="";
How do I write the link? I tried writing a number of variations with the Laravel syntax, where I need to access a route in my ContactController that would go to contacts/{id}. I tried:
window.location="{{URL::to('contacts', $person->id)}}";
That doesn't work. Please let me know what link to use in order to go to contacts/1 or contacts2, for example.

try this.
$('#contacts tbody').on('click', 'tr', function () {
var name = $('td', this).eq(1).text();
var link = $('td', this).eq(0).find('a');
alert('You clicked on ' + name + '\'s row');
window.location=link.attr('href');
});
And the show method only accepts one argument.
<td>
{!! link_to_action('ContactController#show', $person->id) !!}
</td>
And no need to wrap it in "a" tags

Add your link to a data attribute on your tr element and then use it in your JavaScript.
HTML:
<tbody>
#foreach ($people as $person)
<tr data-link='{{ action('ContactController#show', $person->id) }}'>
<td>
<a>{!! link_to_action('ContactController#show', $person->id, $person->id) !!}</a>
</td>
<td>{{ $person->name_first }}</td>
<td>{{ $person->name_middle }}</td>
<td>{{ $person->name_last }}</td>
</tr>
#endforeach
</tbody>
JavaScript:
$('#contacts tbody').on('click', 'tr', function () {
var name = $('td', this).eq(1).text();
alert( 'You clicked on '+name+'\'s row' );
window.location = this.getAttribute('data-link');
} );

AngularJS sorting by time difference

I want to enable sorting by each of my table fields. I have one column which shows how many minutes it took to work on project, but sorting by this field doesn't work properly.
<table>
<th >Company</th>
<th>Time difference<th />
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td >{[{ task.company_name }]}</td>
<td >{[{ timediff(task.time_start,task.time_stop) }]}</td>
</tr>
</table>
timediff function:
$scope.timediff = function(start, end){
var start = moment(start);
var end = moment(end);
var diff = end.diff(start,'minutes',true);
return (diff/60).toPrecision(3);
};
Plunker: http://plnkr.co/edit/vdkfNkgpdLUp9RgZ1IvO?p=preview

Simple fix, just need to assign the function to a parameter
<tr>
<th>Company</th>
<th>Time difference</th>
</tr>
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td>{{ task.company_name }}</td>
<td>{{ task.timediff = timediff(task.time_start,task.time_stop) }}</td>
</tr>
Here is an updated plunker showing this as well as adding a reverse sort.

There is a simpler way for the custom function to work. I edited the dataset a bit to make the switch between "Company" and "Time difference" a bit more clear.
Option 1 (DEMO):
If the property names don't change you can do the following :
$scope.timediff = function(task){
var start = moment(task.time_start);
var end = moment(task.time_stop);
var diff = end.diff(start,'minutes',true);
return (diff/60).toPrecision(3);
};
And in your html assign the function to your sortBy variable:
<th >Company</th>
<th>Time difference</th>
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td >{{ task.company_name }}</td>
<td >{{ timediff(task)}}</td>
</tr>
Angular automatically passes the current item into the function defined in orderBy.
Option 2 (more flexible) (DEMO):
If you want to define the property names on the fly you can return another function:
$scope.timediff = function(name1, name2){
return function(item) {
var start = moment(item[name1]);
var end = moment(item[name2]);
var diff = end.diff(start,'minutes',true);
return (diff/60).toPrecision(3);
}
};
And give it the two property names:
<th >Company</th>
<th>Time difference</th>
<tr ng-repeat="task in tasks | orderBy:sortBy">
<td >{{ task.company_name }}</td>
<td >{{ timediff('time_start', 'time_stop')(task)}}</td>
</tr>
