In my application results are displaying as a table format.
Part of my code is,
{% for device in devices %}
<tr>
<td>{{ device.operator}}</td>
<td>{{ device.state }}</td>
<td>{{ device.tstampgps }}</td>
<td><button id='rec_delete'>Delete</button></td>
</tr>
{% endfor %}
Even if we press the delete button, I need to delete the particular record from the database. before that I want to prompt a confirmation box for that.
Can anyone help me?
Add a unique record Identifier that you can associate to DB to the button. Once confirmed you send this identifier to server with AJAX and sever code does the DB delete. Also change ID to class on repeating elements since ID's must be unique
HTML
<tr>
<td>{{ device.operator}}</td>
<td>{{ device.state }}</td>
<td>{{ device.tstampgps }}</td>
<td><button class='rec_delete' data-record_id="{{ device.DB_ID }}">Delete</button></td>
</tr>
JS
$('button.rec_delete').click(function(){
/* data() method reads the html5 data attribute from html */
var record_id=$(this).data('record_id');
if( confirm( 'Are you sure') ){
$.post( 'serverPage.php', { id: record_id}, function(){
/* code to run on ajax success*/
$(this).closest('tr').remove();
})
}
})
Server will receive the post key id as you would with any other form element name
Since I don't know Django, this doesn't include the delete part, which I assume you will AJAXify that (do an asynchronous request to delete). I'm also showing the $devices and $deletes variables as local variables here separately, more or less so you can see how you can store references and then work from those references (which I believe is a better practice than reselecting over and over).
Note also the use of:
jQuery(document).ready(function r($){
I'm using jQuery() in the global scope, which in a larger app you should always do to keep from conflicting with other libraries/frameworks which may use $(). This is also a best practice, and you can use $() within that anonymous function (closure). It's best to get used to doing it this way, IMO.
<table>
<thead>
<tr>
<th>Operator</th>
<th>State</th>
<th>T-Stamp GPS</th>
<th> </th>
</tr>
</thead>
<tbody>
<tr class="device">
<td>Verizon</td>
<td>OK</td>
<td>033830928</td>
<td>
<button type="button" id="d001" class="delete">Delete</button>
</td>
</tr>
...
</tbody>
</table>
NOTE
I made a slight but important change, with reference to the $self, since the AJAX will run the success handler after this is out of scope:
jQuery(document).ready(function r($){
var $devices = $('tr.device'),
$deletes = $devices.find('button.delete');
$deletes.click(function d(){
var $self = $(this).parents('tr.device'),
del = confirm('Delete device?');
if (del) {
// Do $.ajax() request, maybe using the
// clicked button's ID. Or you could put
// the row to delete ID on the TR element.
// And then on success of the AJAX, run:
$self.fadeOut(500, function f(){
$self.remove();
});
}
});
});

You can add a click event to your JavaScript, and if the user chooses the "ok" button, you can send a request to the view that takes care of removing the record or whatever
Try this:
<button id='rec_delete' onclick="return confirm('Are you sure?')">Delete</button>

In my Vue template, I'm currently setting response data to an object called dateEvents which is structured like this:
<tbody v-for="dateEvent in dateEvents">
<tr>
<td>{{ dateEvent.id }}</td>
<td>{{ dateEvent.status }}</td>
<td><button v-on:click="changeStatus" type="button" class=" taskButton btn-default"><a style="color:white;">Accept</a></button></td>
</tr>
</tbody>
My data shows properly, and I'm calling a method/function with button click, and I can get the click to fire an event but not getting the value properly. I want to have access to the id and status of the clicked row's button within the method but can't figure out how to get it. dateEvent is being set in another function in my vue code so using this.dateEvents gets the base object but I need the specific data sent from the row that is clicked. Here's the vue code:
//vue code
methods: {
changeStatus: function(event) {
alert(this.dateEvents.status)
},
You can pass arguments to the method. In the template:
<button #click="changeStatus(dateEvent)">
And in your method:
changeStatus: function(dateEvent) {
console.log(dateEvent.status, dateEvent.id);
},
I am reading a JSON file, accessed via Python. The values from JSON file will be then displayed on a table. Per row, I have a button. What I want is to see the value when I click the button.
What algorithm I could use in such a way that i could store the ALL values so when I click the button, I can get its corresponding ROW value.
Iteration of my JSON file below:
<tr>
<td align="center">{{ entryIteration.sha1 }}</td>
<td align="center">{{ entryIteration.requestedStatus }}</td>
<td align="center">{{ entryIteration.detectionName }}</td>
<td>{{ entryIteration.userRemarks }}</td>
<td>
Approve
Reject
View
</td>
</tr>
{% endfor %}
$('.btn btn-default').click(function(){
var tdtext1 = $(this).closest('tr').find('.tdclass1')
var tdtext2 = $(this).closest('tr').find('.tdclass2')
})
Use .closest() to get the value of data in the row where the button is
Description: For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.
Ok, so unfortunately I have come across this issue. So first a little about specs of my app.
I am using
Vue.js
vue-resource.js
jQuery
jQuery DataTables
Now because I'm grabbing the data through vue-resource, for some reason when the ajax call is final finished and vue imports the data to the table, datatables decides not to render pagination, and displays all 200 results on one page. Is there anyway to refresh datatables so it is rendered with pagination after it has been imported into the table?
My ajax call:
this.$http.get('getDispachedEmails', function(data){
console.log(data['orders']);
this.customers.push(data['orders']);
var dt = $('#myTable').DataTable();
});
My Table:
<table id="myTable" class="u-full-width">
<thead>
<tr>
<th>Name</th>
<th>Age</th>
<th>Sex</th>
<th>Location</th>
</tr>
</thead>
<tbody>
<tr v-repeat="customers[0]">
<td>#{{ firstName }} #{{ lastName }}</td>
<td>#{{ email }}</td>
<td>#{{ trackingNumber }}</td>
<td>#{{ address }}</td>
</tr>
</tbody>
</table>
EDIT
I have found out that none of the functions work. If i try to select any row, the table is instantly cleaned. My model (vue model) still has all the objects inside.
SOLUTION:
I just set a wait time to initiate data tables after I collect the data via ajax request. It's a little ghetto, but a least it works. If I find a better fix Ill edit this post.
this.$http.get('getDispachedEmails', function(data){
console.log(data['orders']);
this.customers.push(data['orders']);
setTimeout(function(){$('#myTable').DataTable();}, 5000);
});
A delay of 0 did the trick for me, although not sure why.
setTimeout(function(){$('#myTable').DataTable();}, 0);
I've built a dedicated vue grid component: vue-tables . You might want to check it out.
So I have this datatable that is generated by php dynamically once. But once it's loaded, I don't want to reload the whole table since there's only a small javascript if statement that I am doing. When you press the button, I compare a data attribute that is on my tr. If it doesn't fit, I'd like to hide them, else, I'd like to show them. So here is what I tried so far.
HTML
<div style="margin: 30px 0;">
<button class="btn btn-primary" id="myClientButton">Voir mes clients seulements</button>
</div>
<table id="advancedSearchTable">
<thead>
<tr>
<th>Name</th>
<th>Phone</th>
<th>Email</th>
<th>Subject</th>
<th>Date</th>
<th>Profile</th>
</tr>
</thead>
<tbody>
{% for entity in entities %}
<tr data-user="{{ entity.user.id }}" class="values">
<td>{{ entity }}</td>
<td>{{ entity.mainphone }}</td>
<td>{{ entity.email }}</td>
<td>{{ entity.tagline }}</td>
<td>{{ entity.createdDate|date('d-m-Y') }}</td>
<td><span class="glyphicon glyphicon-eye-open"></span></td>
</tr>
{% endfor %}
</tbody>
</table>
The Loop is made in Symfony 2 (Using Twig Template, if you don't understand it it doesn't really matter) all you have to understand is that the attribute on "data-user" is created by PHP and that every entry of my database is going in this loop.
Then, in jQuery I have this:
<script>
$('#advancedSearchTable').DataTable(
{
"language": {
"url": "//cdn.datatables.net/plug- ins/9dcbecd42ad/i18n/French.json"
},
responsive: true
});
$('#myClientButton').on('click', function(){
if ($(this).hasClass('active')){
$(this).removeClass('active');
$('tr.values').show();
}
else{
$(this).addClass('active');
$('tr.values').each(function(){
if ($(this).attr('data-user') != 5){
$(this).hide();
}
});
}
});
</script>
It works very well. The only problem is that the DataTable then is not "replacing itself". So, for example, if it has 25 pages, it keeps 25 pages and when you press on the "next table page" button, it refreshes the "table page" and things are not hidden anymore. I searched alot but I couldn't find a way. I really don't want to use ajax for this, since it only need to be filled once with value and then it will only have to hide or show depending on the button being active or not... Is it even possible using this jQuery plugin ?
Thanks in advance.
Yes, it is indeed possible, but you will need a different approach. Hiding rows with jQuery and not through dataTables itself is generally a bad idea, since dataTables is not aware of changes made to the original <table> element in DOM. There is no "somewhere-in-code-another-script-has-hidden-a-row"-event dataTables can hook into. That is why dataTables seems to "forget" changes, it is simply not aware of those changes, and the dataTables internals stay untouched.
So use a custom filter instead. The following small piece of code does what you want - hiding all rows having a data-user attribute different than 5. It works across sorting and pagination. The last piece of code is an example of a reset-button.
$("#hide").click(function() {
$.fn.dataTable.ext.search.push(
function(settings, data, dataIndex) {
return $(table.row(dataIndex).node()).attr('data-user') == 5;
}
);
table.draw();
});
$("#reset").click(function() {
$.fn.dataTable.ext.search.pop();
table.draw();
});
demo -> http://jsfiddle.net/d5hre2ux/
According to this https://datatables.net/examples/plug-ins/range_filtering.html it is possible to use data parameter to filter by any value shown on the table.
$("button").click(function() {
$.fn.dataTable.ext.search.push(
function(settings, data, dataIndex) {
return data[3] != "63";
}
);
table.draw();
});
On my view I have a few different forms. In one you enter a first and last name to search for. If there are results, the page refreshes and a second form to pick a user is displayed as a table where clicking on a row submits the data from that row. For some reason, submitting the second form results in submitting two values for each field: one completely empty and one with the correct information.
I have some javascript that will be executed when a row in a table is clicked. It's supposed to fill out and submit a hidden form with the data from the table. The problem I'm running into is that when the form is submitted, two sets of values are submitted. request.form after the form is submitted contains the following:
ImmutableMultiDict([('csrf_token', u'1420171907##6ad5346730985191250a52e6432e924ef05c23ee'), ('last_name', u''), ('last_name', u'Smith'), ('first_name', u''), ('first_name', u'John')])
Here's the script:
$('table#theTable tr').click(function () {
var cells = this.getElementsByTagName('td');
$('#selectuser_last_name').val(cells[0].innerHTML);
$('#selectuser_first_name').val(cells[1].innerHTML);
document.selectuser.submit();
});
and here is the HTML to go along with it:
<table id="theTable">
<thead>
<tr>
<th>Last</th>
<th>First</th>
</tr>
</thead>
<tbody>
{% for user in users %}
<tr>
<td>{{ user.last_name }}</td>
<td>{{ user.first_name }}</td>
</tr>
{% endfor %}
</tbody>
</table>
<form id=selectUserForm action="/handle_users" method="post" name="selectuser">
{{ forms.selectuser.hidden_tag() }}
{{ forms.selectuser.last_name(id="selectuser_last_name") }}
{{ forms.selectuser.first_name(id="selectuser_first_name") }}
<input type="submit">Test</input>
</form>
I'm using Python and Flask to handle whatever is posted.
It seems you're actually submitting twice- once before there's anything in the form, and once after it's populated (the latter by the javascript, the former via the form submit mechanism).
If the user isn't really inputting anything into the form, but this is a simple call to the server any time a row is clicked. Skip the whole form, it's not helping here. Just pass a call to the server with the info you need- can be a simple ajax post:
$('table#theTable tr').click(function () {
var cells = this.getElementsByTagName('td');
$.ajax({
type : "POST",
url : "/handle_users",
async:true,
contentType : 'application/json;charset=UTF-8',
data: JSON.stringify({first_name:cells[0].innerHTML,last_name:cells[1].innerHTML}, null, '\t'),
success : function(data) {
// optional: do something when server-side processing is done
}
});
});
Then Grab your data on from flask using request.get_json() in the /handle_users route.
