Ajax call not working on datatables pages,except first page - ajax

i am using datatables.And on the table there is button on each row.
When I click on the trash button,ajax works only for the first 10 row.
But when I move on to next pages it does not work anymore.
Here is my table code:
<script type="text/javascript" language="javascript" src="//cdn.datatables.net/plug-ins/725b2a2115b/integration/bootstrap/3/dataTables.bootstrap.js"></script>
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#example').dataTable();
} );
</script>
<table id="example" class="table table-bordered">
<thead>
<tr>
<th class="success">Id</th>
<th class="success">Image</th>
<th class="success">Title</th>
<th class="success">Action</th>
</tr>
</thead>
<tbody>
<?php
$query = mysqli_query($connect,"SELECT * FROM movie");
while ($result = mysqli_fetch_row($query)){
echo'
<tr>
<td>'.$result[0].'</td>
<td><img class="img-responsive" style="max-height:50px;" src="'.$result[5].'"></td>
<td>'.$result[1].'</td>
<td>
<div class="btn-group" data-toggle="buttons">
<label id="remID" class="btn btn-sm btn-default">
<span class="text-danger glyphicon glyphicon-trash"></span>
</label>
<label class="btn btn-sm btn-default">
<span class="text-primary glyphicon glyphicon-edit"></span>
</label>
</div>
</td>
</tr>
';
echo'
<script>
$(document).ready(function(){
$("#remID").click(function(){
$.post("remMovie.php",
{
id:"'.$result[0].'"
},
function(data,status){
alert(status);
});
});
});
</script>
';
}
?>
</tbody>
</table>
Here is my PHP part of ajax action:
<?php
include('adminchk.php');
include('config.php');
$movieID = $_POST['id'];
$query = mysqli_query($connect,"DELETE from movie where id='$movieID'");
if ($query){
echo"movie deleted";
}
else {
echo"ERROR!";
}
?>
I dont know why this is happening.I want the trash button to work for every row of datatable.

To execute any Code after the Data Table has been paginated (basically redrawn), you need to add fnDrawCallback function inside .dataTabale() method. All codes written inside the Callback function will work after the table has been redrawn. Here is an example...
$(document).ready( function() {
$('#example').dataTable({
"fnDrawCallback": function( oSettings ) {
// Write any code (also ajax code that you want to execute)
// that you want to be executed after
// the table has been redrawn
}
});
});

You should try something like fnDrawCallback event.
Here is the doc : http://legacy.datatables.net/usage/callbacks#fnDrawCallback
When the datable change, you bind the buttons with the function you want.
JS :
$(document).ready( function() {
$('#example').dataTable( {
"fnDrawCallback": function( oSettings ) {
alert( 'DataTables has redrawn the table' );
}
} );
} );

How to reload the data of a table with vue and axios?

Well, i have a table populated with v-for: "usuario in usuarios". The initial charge does it correctly. But when i push the button "Buscar" only my <p>{{nombre}}</p> shows data. Look at these pictures:
Table populated with data
In the above picture, the table was populated with data, through getUsuarios() method. But in the next picture the table only shows blank data.
Table with blank data and <p>{{nombre}}</p>
Here are my codes:
Template:
<div>
<div class="panel panel-default">
<div class="panel-heading"><h1><strong>Lista de nombres</strong></h1></div>
<div class="panel-body">
<table class="table table-hover table-bordered table-striped">
<thead>
<tr>
<th>Nombre</th>
<th>Apellido Paterno</th>
<th>Apellido Materno</th>
</tr>
</thead>
<tbody>
<tr v-for="usuario in usuarios">
<td>{{usuario.Nombre}}</td>
<td>{{usuario.Apellido_P}}</td>
<td>{{usuario.Apellido_M}}</td>
</tr>
</tbody>
</table>
</div>
</div>
<br />
<p>Buscar usuario</p>
<div class="form-group">
<div class="input-group">
<input type="text" class="form-control" v-model="busqueda" placeholder="Buscar usuario" />
<button class="btn btn-default" v-on:click="buscarUsuario">Buscar</button>
</div>
<p>{{nombre}}</p>
</div>
</div>
</template>
Script
<script>
import axios from 'axios'
export default {
data() {
return {
usuarios:[],
busqueda: '',
nombre: '',
}
},
methods: {
buscarUsuario() {
axios.get('http://localhost:50995/api/GetUsuario?id=' + this.busqueda)
.then(response => {
this.usuarios = response.data,
this.nombre = response.data.Nombre
}).catch(e => {
console.log(e)
})
},
getUsuarios() {
axios.get("http://localhost:50995/api/GetUsuarios")
.then(response => {
this.usuarios = response.data
})
.catch(e => {
console.log(e)
})
}
},
created() {
this.getUsuarios(),
this.buscarUsuario()
}
}
</script>
As you can see, the <p>{{nombre}}</p> is populated with the data of the ID that i put in the input. But the table only shows blank data.
The <p>{{nombre}}</p> is only for test if the buscarUsuario() method works, and it's works but not with the table.
And, how can i reload the data of the table with the properties of the ID when i push the "Buscar" button?
Thank you
Something is wrong in your buscarUsuario() logic: you are overwriting the initial correct array of usuario objects with a single object of one usuario
axios.get('http://localhost:50995/api/GetUsuario?id=' + this.busqueda)
.then(response => {
/* REMOVE THIS LINE */ this.usuarios = response.data,
this.nombre = response.data.Nombre
}).catch(e => {
console.log(e)
})

Display Data Got From JSON In Reactjs In Table

Here I wrote A code which fetches data from API http://fcctop100.herokuapp.com/api/fccusers/top/recent and displays Data in Form Of Table Which Looks Like Below In My Case As You Can See is Repeating For Every
But I want To Make It Look Like
Here Is What I Did So Far
var MainBox = React.createClass({
render:function(){
return(
<App/>
);
}
});
var App = React.createClass({
//setting up initial state
getInitialState:function(){
return{
data:[]
};
},
componentDidMount(){
this.getDataFromServer('http://fcctop100.herokuapp.com/api/fccusers/top/recent');
},
//showResult Method
showResult: function(response) {
this.setState({
data: response
});
},
//making ajax call to get data from server
getDataFromServer:function(URL){
$.ajax({
type:"GET",
dataType:"json",
url:URL,
success: function(response) {
this.showResult(response);
}.bind(this),
error: function(xhr, status, err) {
console.error(this.props.url, status, err.toString());
}.bind(this)
});
},
render:function(){
return(
<div>
<Result result={this.state.data}/>
</div>
);
}
});
var Result = React.createClass({
render:function(){
var result = this.props.result.map(function(result,index){
return <ResultItem key={index} user={ result } />
});
return(
<div>
{result}
</div>
);
}
});
var ResultItem = React.createClass({
render:function(){
var camper = this.props.user;
return(
<div className="row">
<div className="col-md-12">
<table className="table table-bordered">
<thead>
<tr>
<th className="col-md-4">UserName</th>
<th >Points In Last 30 Days</th>
<th>Points All Time</th>
</tr>
</thead>
<tbody>
<tr >
<td>{camper.username}</td>
<td>{camper.recent}</td>
<td>{camper.alltime}</td>
</tr>
</tbody>
</table>
</div>
</div>
);
}
});
ReactDOM.render(
<MainBox />,
document.querySelector("#app")
);

The following should list all your items as a single row in your table, and only give you one table. One tip is to not use the index as the key for your map function. It's better to use some natural key or identifier in your result, some kind of id that will enable React better comparison of the components. A blog post describing this and some documentation.
var Result = React.createClass({
render:function(){
var result = this.props.result.map(function(result,index){
return <ResultItem key={index} user={ result } />
});
return(
<div className="row">
<div className="col-md-12">
<table className="table table-bordered">
<thead>
<tr>
<th className="col-md-4">UserName</th>
<th >Points In Last 30 Days</th>
<th>Points All Time</th>
</tr>
</thead>
<tbody>
{result}
</tbody>
</table>
</div>
</div>
);
}
});
var ResultItem = React.createClass({
render:function(){
var camper = this.props.user;
return(
<tr >
<td>{camper.username}</td>
<td>{camper.recent}</td>
<td>{camper.alltime}</td>
</tr>
);
}
});

laravel delete is not working

I am wondering how to put a csrf token in a form so that delete will work?
Here is my code:
Route:
Route::delete('category_delete/{id}',['as'=>'category_delete','uses'=>'CategoryController#destroy']);
index.blade.php
#section('adminContent')
{!! Form::token() !!}
<div class="table-responsive art-content">
<table class="table table-hover table-striped">
<thead>
<th> NAME</th>
<th> ACTIONS</th>
</thead>
<tbody>
#foreach($categoriesView as $category)
<tr>
<td>{!! $category->name!!}</td>
<td>{!! link_to_route('categories.edit', '', array($category->id),array('class' => 'fa fa-pencil fa-fw')) !!}</td>
<td><button type="button" id="delete-button" class="delete-button" data-url = "{!! url('category_delete')."/".$category->id !!}"><i class="fa fa-trash-o"></i></button>
</td>
</tr>
#endforeach
</tbody>
</table>
<div class="pagination"> {!! $categoriesView->render() !!}</div>
</div>
#stop
CategoryController:
public function destroy($id,Category $category)
{
$category = $category->find ( $id );
$category->delete ();
Session::flash ( 'message', 'The category was successfully deleted!.' );
Session::flash ( 'flash_type', 'alert-success' );
}
If I used ajax, javascript or jquery, how should the code be?
Using jquery I would do something like the following.
Add the line below in the header of your home view
<meta name="csrf-token" content="{{ csrf_token() }}" />
Now in your javascript
function deleteMe(button)
{
// You might want to put the ajaxSetup function where it will always load globally.
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
if(confirm("Are you sure?"))
{
$.get(
'category_delete/'+button.id,
function( response )
{
// callback is called when the delete is done.
console.log('message = '+ response.message);
}
)
}
}
In index.blade.php, make your id more specific.
...
<td><button type="button" id=".$category->id" class="delete-button" data-url = "{!! url('category_delete')."/".$category->id !!}"><i class="fa fa-trash-o" onlick="deleteMe(this);></i></button>
...
In your controller
public function destroy($id,Category $category){
$category = $category->find ( $id );
$category->delete ();
return response()->json(
'message' => 'Deleted',
)
}
Note: No need to add
Form::token in your view
Hope this helps.....
Updated...........
If you were to do it using laravel only, I will suggest you use a link rather than the button you are using.
In index.blade.php, make your id more specific.
...
<td><a href="category_delete/".$category->id class="delete-button" data-url = "{!! url('category_delete')!!}"><i class="fa fa-trash-o"></i></td>
...
In your controller
public function destroy($id,Category $category){
$category = $category->find ( $id );
$category->delete ();
return view('index');//important.
}
If you want your link to look like a button, use css or a css framework like bootstrap
That should be it. hope this helps again.

Get database record using AJAX, Knockout and JSON

I am fairly new to Knockout and Entity Framework and I have a problem where I cannot seem to output any JSON from an MVC 4 controller action via an AJAX call using Knockout onto an html page.
The table includes fields Email and RegsitrationNumber, these are used to validate the user.
If the user exists in the table then their country is displayed on the screen.
The profiler states a Status Code of 200 i.e OK. Can anyone help?

How to submit form using ajax inside wordpress plugin

I am creating small plugin where i want to submit form data using ajax but it giving response zero.
Here is my call i have added all code in a single file for the time being
file name :index.php
<?php wp_enqueue_script("jquery");?>
<?php
function myaddgallery(){
global $wpdb;
echo "abac";
}
add_action('wp_ajax_myaddgallery' , 'myaddgallery');
add_action('wp_ajax_nopriv_myaddgallery' , 'myaddgallery');
?>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#shaGalleryForm').submit(function(e){
// prevent normal submit behaviour
e.preventDefault();
var name = jQuery("#shaGalleryName").val();
alert(name);
//var postData = jQuery("#shaGalleryForm").serialize();
//console.log(postData);
var name = "shalu";
jQuery.ajax({
type: "POST",
url: "http://localhost/plugindevelop/wp-admin/admin-ajax.php",
data : {action: "myaddgallery", name : name},
success: function(response){
//console.log(postData);
console.log("added success");
alert(response);
},
error: function(data){
console.log("fail");
}
});
});
}) ;
</script>
<div class='wrap'>
<h2>Add Gallery</h2>
<p>This is where from you can create new gallery</p>
<form name="shaGalleryForm" id="shaGalleryForm" method="post">
<table class="form-table">
<tr>
<th>Gallery Name</th>
<td>
<input type="text" id="shaGalleryName" name="shaGalleryName">
<p class="description">Add gallery name also please avoid special character</p>
</td>
</tr>
</table>
<p class="submit">
<input type="submit" value="Save" id="shaSaveGallery" name="shaSaveGallery" class="button button-primary">
</p>
</form>
</div>
Try to add die() after you echo the data
function myaddgallery(){
global $wpdb;
echo "abac";
die();
}
