I'm trying add data to DB and show these data in same page using ajax and jQuery datatable without reloading or refreshing page. My code is saving and retrieving data to/from database. But updated data list is not showing in datatable without typing in search box or clicking on table header. Facing same problem while loading page.
Here is my code
//show data page onload
$(document).ready(function() {
catTable = $('#cat_table').DataTable( {
columns: [
{ title: "Name" },
{ title: "Level" },
{ title: "Create Date" },
{ title: "Status" }
]
});
get_cat_list();
});
//save new entry and refresh data list
$.ajax({
url: 'category_save.php',
type: 'POST',
data:{name: name,level: level},
success: function (data) {
get_cat_list();
},
error: function (data) {
alert(data);
}
});
//function to retrieve data from database
function get_cat_list() {
catTable.clear();
$.ajax({
url: 'get_category_list.php',
dataType: 'JSON',
success: function (data) {
$.each(data, function() {
catTable.row.add([
this.name,
this.level,
this.create_date,
this.status
] );
});
}
});
}
The solution is here - for DataTable server side data source enabled
.draw() will cause your entire datatable to reload, say you set it to show 100 rows, after called .row().add().draw() > datatable will reload the 100 rows again from the server
I wasted an hour trying to find any solution for this very old question, even on DataTable official support there is no good solution suggested ...
My solution is
1- call .row().add()
2- do not call .draw()
3- your row must have an Id identifier to use it as a selector (check the rowId setting of the datatable)
4- after calling .row().add(), the datatable will have the row added to it's local data
5- we need to get this row from datatable object and transform it to HTML using the builtin method .node()
6- we gonna prepend the result HTML to the table :)
All that can be done in two lines of code
var rowData = someRowCreatedByAnAjaxRequest;
myDataTableObject.row.add(rowData);
$("#myTable-dt tbody").prepend(myDataTableObject.row(`tr#${rowData.Id}`).node().outerHTML)
Thanks ☺
From the documentation,
This method will add the data to the table internally, but does not
visually update the tables display to account for this new data.
In order to have the table's display updated, use the draw() method, which can be called simply as a chained method of the row.add() method's returned object.
So you success method would look something like this,
$.each(data, function() {
catTable.row.add([
this.name,
this.level,
this.create_date,
this.status
]).draw();
});

I am desperately trying to submit multiple POST variables via AJAX, but just cant get manage to get the formatting right... Problem is that I have both a hardcoded / written action=problem_lookup variable and a dynamic field input as $(this).val and just cant manage to get both into one data string...
this works well:
data: 'problem=' + $(this).val(),
This does not:
data: { action: 'problem_lookup' , problem: $("problem").val() },
data: { action: 'problem_lookup' , problem: $(this).val() },
data: { action: problem_lookup, problem: $(this).val() },
I tried numerous formats from other threads and looked at the official jquery manual, but cant seem to get this figured out. Any help is appreciated.
EDIT:
full script below, tried the solutions posted so far but no success. $("problem") is a <select> field (with Select2 running) hence shouldnt cause me so much frustration, especially since the original approach with data: 'problem=' + $(this).val(), works fine.
$(function () {
$('#problem').change(function () { // on change in field "problem"
var data = {
action: 'problem_lookup',
problem: $("problem").val()
}
$.ajax({ // launch AJAX connection
type: 'POST', // via protocol POST
url: 'ajax.php',
//data: 'problem=' + $(this).val(), // send $_POST string
//data:"{'action':'"+action+"','problem':'"+$(this).val()+"'}",
//data:"{'action':'problem_lookup','problem':'"+$(this).val()+"'}",
//data: { action: 'problem_lookup' , problem: $("problem").val() },
//data : data_string,
data: $.param(data),
dataType: 'json', // encode with JSON
success: function (data)
{
// do something
},
});
});
});
An issue is in the
$("problem")
Jquery call.
If.problem is a css class try with
$(".problem")
if problem is a css id try with
$("#problem")
For posting arrays of object you can build data as an object containing arrays, changing a little bit your structure. Something like this
Var obj={};
obj.postData=[];
obj.postData.push(/*your first object here*/);
...
obj.postData.push(/*your n-th object here*/);
$.ajax({
.....
data:obj;
......
});
Try the FormData() FormData.
var data = new FormData();
data.append('action', value);
...
You need to specify your data variable first like this:
var data = {
action: 'problem_lookup',
problem: $("problem").val()
}
In AJAX serialize your data using $.param,
data: $.param(data),
Note: Twice check if $("problem").val() is correct. If problem is a class, you need to specify like this $(".problem").val() or if it is ID, $("#problem").val()
i have been able to fetch data with an ajax call from active directory .
the php file used to make the ajax call to active directory :http://pastebin.com/tSRxwQL8
The browser console shows that an ajax call returns this :
<p> sn: xxxxxx<br/>givenname: xxxxx<br/>
employeeID: 0050<br/
>distinguishedName: CN=xxxx xxxxx,OU=Employees,OU=Accounts,OU=India,DC=asia,DC=xxxxxxx,DC=com<br/>
displayName: Mark Hewettk<br/>sAMAccountName: xxxxxxx<br/>
department: xxxxx<br/>manager: CN=xxxxxx xxxxxxx,OU=Employees,OU=Accounts,OU=India,DC=asia,DC=xxxx,DC=com
<br/>
mail: mhewettk#abc.com<br/>
title: xyz<br/>
I want to take only some attributes above like mail,displayname etc and display in my HTML :
<h2 class="profile__name" id="emailOfUser">Email : </h2>
Now the problem is the jquery that I have used here :
$('.leaderboard li').on('click', function() {
$.ajax({
url: "../popupData/activedirectory.php", // your script above a little adjusted
type: "POST",
data: {
id: $(this).find('.parent-div').data('name')
},
success: function(data) {
console.log(data);
$('#popup').fadeIn();
$('#emailOfUser').html(data); //this line displays all data whereas I want to select only email,displayname from the above console data
//whatever you want to fetch ......
// etc ..
},
error: function() {
alert('failed, possible script does not exist');
}
});
});
problem is this :
$('#emailOfUser').html(data);
this line displays all data whereas I want to select only email,displayname from the above console data
kindly help me how to select only desired attribute data from the above browser console data.
Ideally you should return JSON from PHP file, however if it is not possible for you to make changes to PHP file then you can use split("mail:") and split("title:") to extract data
success: function(data) {
console.log(data);
$('#popup').fadeIn();
var email=(data.split("mail:")[1]).split("title:")[0];
$('#emailOfUser').html(email); //this line displays all data whereas I want to select only email,displayname from the above console data
//whatever you want to fetch ......
// etc ..
},
You are getting response in HTML which makes difficult for you to extract mail, displayname, etc.
You should get the response in JSON which will make it easy for you to extract the required info.
Ask your back-end team to send response in JSON format.
Working Fiddle
Try :
var lines = 'sn: xxxxxx<br/>givenname: xxxxx<br/>employeeID: 0050<br/>distinguishedName: CN=xxxxxxxxx,OU=Employees,OU=Accounts,OU=India,DC=asia,DC=xxxxxxx,DC=com<br/>displayName: Mark Hewettk<br/>sAMAccountName: xxxxxxx<br/>department: xxxxx<br/>manager: CN=xxxxxx xxxxxxx,OU=Employees,OU=Accounts,OU=India,DC=asia,DC=xxxx,DC=com<br/>mail:mhewettk#abc.com<br/>title:xyz<br/>'.split('<br/>');
jQuery.each(lines, function() {
var val = this;
if (val.indexOf('mail') > -1)
// alert(val.split(':')[1]); //Only for test
$('#emailOfUser').html(val.split(':')[1]);
});
I have a DataTables (datatables.net) table setup which have a custom column where I have icons for different kind of actions.
One of these actions is deletion and I don't want to reload the data into the table so I was wondering if there was any function built-in for removal of datatable rows locally (so my script deletes the actual post on the server and then I can remove the same row in my datatable).
After some research I've found "fnDeleteRow" but I don't know how to use it. In my script I have an ajax call and on the success event I want to delete the row but I have trouble identifying what row that had the link was clicked. This below is where I am at the moment:
function Delete(id) {
$.ajax({
url: "ajax/ajax.php",
type: "POST",
data: {
action: "delete",
id: id
},
success: function(response){
oTable = $('#table').DataTable();
var row = oTable.closest('tr');
var nRow = row[0];
oTable.DataTable().fnDeleteRow(nRow);
},
error: function (response) {
alert("Something went wrong.");
console.log(response);
},
});
};
This prints the following in the console:
TypeError: oTable.closest is not a function
I'm pretty new to jQuery and don't know how to implement this to my case. Do anyone of you have any idea? I'm guessing that even if my script within the success event had the right syntax, it won't have a clue what row had the button/link that was clicked at the first place. How do I ensure it does?
EDIT:
This is how my datatable is initiated, in case it is confusing:
function DrawTable() {
$('#table').DataTable( {
"cache": false,
"columnDefs": [
{
"targets": [ 0, 1 ],
"visible": false,
"searchable": true
}
]
} );
}
I was told to use a jsfiddle, so I've uploaded one. Never used this site and my markup is generated but I manually did one.

Maybe it's too late, but I will put it anyway. After two days of searching all over the web, I find a simple solution without any DataTable functions
<td>
<button type="button" id="{{$lead->id}}" name="{{$lead->id}}" onclick="deleteRecord(this.id,this)" data-token="{{ csrf_token() }}">Delete</button>
</td>
this cell above has an onclick function that takes 2 parameters, the first one (this.id) is the id of the button (that comes from the DB, and will be passed to ajax to update the DB), and the second one (this) which is the index of the button itself (later we will extract the index of the row from it)
function deleteRecord(mech_id,row_index) {
$.ajax({
url:"{{action('MechanicController#destroy')}}",
type: 'get',
data: {
"id": mech_id,
"_token": token,
},
success: function ()
{
var i = row_index.parentNode.parentNode.rowIndex;
document.getElementById("table1").deleteRow(i);
}
});
}
Now in the success function, I have used 2 lines:
the first one is to extract the row index from the button (2 parents because we have to pass from the parent of the button, in this case , and then the parent of the which is the row)
the second line is a simple delete row of our index from table1 which is the name of my table
I am using jQuery to delete some data from database. I want some functionality that when jQuery returns success I want to execute a query. I want to update a another table on success of jQuery without page refresh. Can I do this and if yes how can I do this?
I am newbie to jQuery so please don't mind if it's not a good question for stackoverflow.
This is my script:
<script type="text/javascript">
$(document).ready(function () {
function delete_comment(autoid, btn_primary_ref) {
$.ajax({
url: 'rootbase.php?do=task_manager&element=delete_comment',
type: "POST",
dataType: 'html',
data: {
autoid: autoid
},
success: function (data) {
// I want to execute the Update Query Here
alert("Comment Deleted Successfully");
$(btn_primary_ref).parent().parent().hide();
var first_visible_comment = $(btn_primary_ref).parent().parent().parent().children().find('div:visible:first').eq(0).children('label').text();
if (first_visible_comment == "") {} else {
$(btn_primary_ref).parent().parent().parent().parent().parent().parent().prev().children().text(first_visible_comment);
}
load_comment_function_submit_button(autoid, btn_primary_ref);
},
});
}
$(document).on('click', '.delete_user_comment', function (event) {
var autoid = $(this).attr('id');
var btn_primary_ref = $(this);
var r = confirm("Are you sure to delete a comment");
if (r == true) {
delete_comment(autoid, btn_primary_ref);
} else {
return false;
}
});
});
</script>
You can't do database operations directly in Javascript. What you need to do is to simply make a new AJAX request on success to a php file on the backend to update given table. However this would mean two AJAX requests to the backend, both of which manages database data. Seems a bit unnecessary. Why not just do the update operation after the delete operation in the php file itself?
add a server sided coded page that will execute your query.
example :
lets say you add a page named executequery.php.
with this code:
when you want to execute your query do the following :
$.post("executequery.php",//the URL of the page
{
param1:value1,
param2:value2....//if you want to pass some parameters to the page if not set it to null or {}
},
function(data){
//this is the callback that get executed after the page finished executing the code in it
//the "data" variable contain what the page returened
}
);
PS : tha paramters sent to the page are conidired like $_POST variables in the php page
there is an other solution but its UNSAFE i recomand to NOT use it.
its to send the query with the paramters and that way you can execute the any query with the same page example :
$.post("executequery.php",//the URL of the page
{
query:"insert into table values("
param1:value1,
param2:value2....//if you want to pass some parameters to the page if not set it to null or {}
},
function(data){});
please pardon my noobness, but I'm new to working with Telerik controls. I have seen many examples of this but they haven't been able to solve my problem. I have a Kendo UI multiselect widget which contains some items and a button which, on clicking, would fill the multiselect widget partially with some items. These items are obtained as JSON from a controller method (ASP.NET MVC). So, the button click actually fires an ajax request and on successfully firing up, it calls a javascript function to fill the multiselect widget up. As of now, the ajax gets fired successfully and the data that I want is coming back successfully, just that the multiselect is not displaying the values.
My javascript/AJAX methods:
function addItems(items) {
var values = new Array();
for (var i = 0; i < items.length; i++) {
values[i] = items[i].Item.ID;
// gets values back correctly
console.log(values[i]);
}
// print values
$('#items').data("kendoMultiSelect").value(['"' + values + '"']);
};
// success
$(document).on("click", "#add-items-button", function () {
var myUrl = $('#MyURL').val();
$.ajax({
url: myUrl, // get URL from view
method: 'GET',
dataType: 'json',
success: function (data) {
addItems(data);
},
error: function (xhr, status, error) {
console.log(error);
}
});
});
My multiselect widget is a partial view so:
#using Kendo.Mvc.UI
#(Html.Kendo().MultiSelect()
.Name("items") // Name of the widget should be the same as the name of the property
.DataValueField("ID")
.DataTextField("Name")
.BindTo((System.Collections.IEnumerable)ViewData["items"])
.Placeholder("Add Items")
)
Am I missing something very obvious? Am I writing the data back in an incorrect format to the multiselect widget? Please help.
You need to add items to the data source of the multiselect.
$('#items').data("kendoMultiSelect").dataSource.add( { ID: 1, Name: "Name" });
Here is a live demo: http://jsbin.com/eseYidIt/1/edit
It might help to others
var multiSelect = $('#mymultiSelect').data('kendoMultiSelect');
var val = multiSelect.value().slice();
$.merge(val, "anil.singh#hotmail.com");
multiSelect.value(val);
multiSelect.refresh();
OR
$('#mymultiSelect').data("kendoMultiSelect").dataSource.add({Id:"EMP100XYZ",
EmailId: "ayz#gmail.com" });
