I am binding data to jquery datatable in asp.net mvc, i have an anchor tag in one of the columns of the grid where i am accessing / reading row data and sending that data to a javascript function. The problem which i am facing is, i am able read and send row values to the function which are numbers for example ProductID="1" or CategoryID="3" , but if i try to send ProductName="Chai" to the javscript function i get an error in the console, and if i remove the parameter "ProductName" everything works fine and the javascript function also gets triggered.
Following the console error:
"Index:1 Uncaught ReferenceError: Chai is not defined
at HTMLAnchorElement.onclick (Index:1)"
Following is my Code:
var BindDataTable = function (response) {
$("#tbProduct").DataTable({
"aaData": response,
"aoColumns": [
{ "mData": "ProductID" },
{ "mData": "ProductName" },
{ "mData": "SupplierID" },
{ "mData": "SupplierName" },
{ "mData": "SupplierCountry" },
{ "mData": "CategoryID" },
{ "mData": "CategoryName" },
{ "mData": "QuantityPerUnit" },
{ "mData": "UnitPrice" },
{
"render": function (data, type, full, meta) {
return '<i class="glyphicon glyphicon-pencil"></i>'
}
}
],
"columnDefs": [
{
"targets": [2],
"visible": false,
"searchable": false
},
{
"targets": [5],
"visible": false,
"searchable": false
}
],
"aaSorting": []
});
}
var EditProduct = function (ProductID, SuppID, CatID,PrdName) {
var url = "/Product/EditProduct?ProductID=" + ProductID + "&SuppID=" + SuppID + "&CatID=" + CatID;
$("#myModalBodyDiv1").load(url, function () {
$("#myModal1").modal("show");
})
}
Error:
My suggestion is that instead of playing around with that much string concatenations, what you can do is pass single object to your function and then use the required fields which needs to be passed as ajax call:
"render": function (data, type, full, meta) {
return '<i class="glyphicon glyphicon-pencil"></i>'
}
and in your js function use it :
var EditProduct = function (product) {
var url = "/Product/EditProduct?ProductID=" + product.ProductID+ "&SuppID=" + product.SupplierID + "&CatID=" + productCategoryID + "&ProdName=" + product.Prooductname ;
You can use the following approach in for passing string arguments to a JavaScript function:
<a onclick="javaScriptFunction(#p.ID, '#p.FileName');">#p.FileName</a>
function javaScriptFunction(id, fileName) {
...
}

I have a simple datatable that shows some JSON data, received from an API endpoint.
I added a column that will hold a button on each row of the table. This button, when hit, will fire an AJAX request with the value of id for that specific row.
This actual code works, but now, instead of only sending the value of id, i would also like to edit the table so that, when the button is hit, it will send the values of id and item for that row. Can someone give me some piece of advice on how to do that?
On another question, i've been told to use Data Attributes, but i don't really know how would i integrate this into my current code. Any advice is appreciated.
$(document).ready(function() {
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
console.log(statusVal)
callAJAX("/request_handler", {
"X-CSRFToken": getCookie("csrftoken")
}, parameters = {
'orderid': statusVal
}, 'post', function(data) {
console.log(data)
}, null, null);
return false;
});
let orderstable = $('#mytalbe').DataTable({
"ajax": "/myview",
"dataType": 'json',
"dataSrc": '',
"columns": [{
"data": "item"
}, {
"data": "price"
}, {
"data": "id"
},],
"columnDefs": [{
"targets": [2],
"searchable": false,
"orderable": false,
"render": function(data, type, full) {
return '<button type="button" class="btnClick sellbtn" data-status="replace">Submit</button>'.replace("replace", data);
}
}]
});
});
You could use the full parameter of the DataTables render function to store the values of the current seleceted row. In this way:
return '<button type="button" class="btnClick sellbtn" data-status="' + btoa(JSON.stringify(full)) + '">Submit</button>';
In the above code, the data-status data attribute will contains the stringified version of the current object value in base64 by using btoa(). In base64 because for some reason we cannot directly store the stringified version of the object in the button's data attribute.
Then, in the button's click event, you have to do:
Decode the stringified object by using atob().
Parse into object by using JSON.parse().
Something like this:
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
// Decode the stringified object.
statusVal = atob(statusVal);
// Parse into object.
statusVal = JSON.parse(statusVal);
// This object contains the data of the selected row through the button.
console.log(statusVal);
return false;
});
Then, when you click in the button you will see this:
So, now you can use this object to send in your callAJAX() function.
See in this example:
$(function() {
$(document).on('click', '.btnClick', function() {
var statusVal = $(this).data("status");
// Decode the stringified object.
statusVal = atob(statusVal);
// Parse into object.
statusVal = JSON.parse(statusVal);
// This object contains the data of the selected row through the button.
console.log(statusVal);
return false;
});
let dataSet = [{
"id": 1,
"item": "Item 1",
"price": 223.22
},
{
"id": 2,
"item": "Item 2",
"price": 243.22
},
{
"id": 3,
"item": "Item 3",
"price": 143.43
},
];
let orderstable = $('#myTable').DataTable({
"data": dataSet,
"columns": [{
"data": "item"
}, {
"data": "price"
}, {
"data": "id"
}, ],
"columnDefs": [{
"targets": [2],
"searchable": false,
"orderable": false,
"render": function(data, type, full) {
// Encode the stringified object into base64.
return '<button type="button" class="btnClick sellbtn" data-status="' + btoa(JSON.stringify(full)) + '">Submit</button>';
}
}]
});
});

Hope this helps!
I am trying to get the <span> tag into the "salesStatusName" column cell that already has some data in it. The tag should be placed in there when the value of the last column "completelyDelivered" is true. However, I also don't want "completelyDelivered" to even be a column in the table, so I assume I somehow need to access the value of "completelyDelivered" attribute in the received JSON.
How it looks now:
https://i.imgur.com/S171i2o.png circle in a separate column
How I want it to look:
https://i.imgur.com/74nCnGu.png circle within Status Name column
I looked around and there are very similar questions, but I was unable to implement any solution.
DataTables instantiation code:
Note that I use AJAX and get JSON code returned
$(document).ready(function () {
$.fn.dataTable.moment('MM-DD-YYYY');
var datatableObj = $('#salesOrdersTable').DataTable({
"ajax": {
"url": "/Orders/GetAll",
"type": "GET",
error: function (error) {
RedirectUserToErrorPage();
}
},
"columns": [
{ "data": "salesOrderNumber" },
{ "data": "salesOrderNumber" },
{ "data": "poNumber" },
{ "data": "orderDateString" },
{ "data": "company" },
{ "data": "salesPerson" },
{ "data": "salesStatusName" },
{ "data": "completelyDelivered" }
],
"columnDefs": [
{
"targets": 0, //salesOrderNumber col
"orderable": false,
"render": function (data) {
return '<input type="button" value="+" onclick="location.href=\'/Shipments/Get?salesOrderNumber=' + data + '\'">';
}
},
{
"targets": 7, //completelyDelivered col
"render": function (data) {
if (String(data) == "true") {
return '<span class="SalesOrderDelivered">⬤</span>';
}
return "";
}
},
{ className: "salesOrderNumber", "targets": 1 },
],
});
I've done some research and figured it out.
Basically, if you write { "data": null }, as a definition for a column, you gain access to all properties of that row. So, in "render": function(data) function, write data["propertyName"] to get the value.
Code:
$(document).ready(function () {
$.fn.dataTable.moment('MM-DD-YYYY');
var datatableObj = $('#salesOrdersTable').DataTable({
"ajax": {
"url": "/Orders/GetAll",
"type": "GET",
error: function (error) {
RedirectUserToErrorPage();
}
},
{"data": "salesOrderNumber",},
{ "data": "salesOrderNumber" },
{ "data": "poNumber" },
{ "data": "orderDateString" },
{ "data": "company" },
{ "data": "salesPerson" },
{ "data": null, },//this is Sales Status column.
//"data: null" accesses all JSON data. We need this so that in "columnDefs" section
//we can use the values of both "completelyDelivered" and "salesStatusName" properties.
],
"columnDefs": [
{
"targets": 0, //button col
"orderable": false,
"render": function (data) {
return '<input type="button" value="+" onclick="location.href=\'/Shipments/GetShipments?salesOrderNumber=' + data + '\'">';
}
},
{
"targets": 6, //Sales Status col.
"render": function (data) { //This is where we can use values of "completelyDelivered" and "salesStatusName" JSON properties.
if (String(data["completelyDelivered"]) == "true") {
return (String(data["salesStatusName"]) + '<span class="AllDelivered"> ⬤</span>');
} else {
return String(data["salesStatusName"]);
}
}
},
{ className: "salesOrderNumber", "targets": 1 },
],
});
I have created a query table using data from json.
I am trying to combine two column values in one
but i always get undefined data when i try to combine two columns.
I am not sure what is wrong here.
not sure what is wrong here
$("#submit").click(function(){
var dataTableExample = $('#tbl_jad').DataTable();
$('#tbl_jad').show();
if (dataTableExample != 'undefined') {
dataTableExample.destroy();
}
dataTableExample =
$('#tbl_jad').DataTable({
"aaData": data.d.results,
"aoColumns": [
{
"mData": "ID"
},
{
"mData": "Position_x0020_Number",
},
{
"mData": "Title"
}, {
"mData": "Type_x0020_of_x0020_Action"
}, {
"mData": "Series"
}]
,
"columnDefs": [
{
"render": function ( data, type, row ) {
return data +' ('+ row[0]+')';
},
"targets": 1
},
{ "visible": false, "targets": [ 0 ] }
]
});
}
});
return data +' ('+ row["ID"]+')'
where ID is the column heading or column name
I'm using Datatables and I'm trying to access data in another column. It's unclear to me if I should be using columns.data or if I should be taking another approach by using getting the column index instead?
Objective
In the second render function, I want the first makeSlug(data) to be referencing the "data": "district" and the second one to remain the same and reference "data": "school"
scripts.js
"columns": [
{ "data": "district",
"render": function (data, type, row, meta) {
return '' + data + '';
}
},
{ "data": "school",
"render": function (data, type, row, meta) {
return '' + data + '';
}
},
{ "data": "subject"},
{ "data": "rate"},
{ "data": "test_takers"}
],
Third argument row is an array containing full data set for the row. Use row['district'] to access district property.
For example:
{
"data": "school",
"render": function (data, type, row, meta) {
return '' + data + '';
}
}
I have a set of JSON data that are displayed using datatables. In one of the columns, I add a button and a text box only if the value in that column and another column meets a certain condition. this is the bit of code I used to do this:
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<form><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert" onclick="<get all items for that row and POST to a URL>"></form>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
});
This works fine by adding a button and text in the cell. What I am looking to achieve is, when any of the button is been clicked, it should POST all the values for that row including what is typed in the text box to a URL which has another function that would extract those details and update the database and send back the refreshed data. I am new to datatables and jquery, any guide would be highly appreciated.
Have made some changes to the code, instead of form you can use div.
$(document).ready(function (){
var alertTable = $('#alert-table').DataTable({
"jQueryUI": true,
"order": [ 3, 'desc' ],
"columns": [
{ "data": "source", "visible": false },
{ "data": "host" },
{ "data": "priority" },
{ "data": "ack", "render": function( data, type, row ) {
if (row.ack == "0" && row.priority > "2") {
return '<div><input class="ackname" type="text" value="Enter your name"><input class="ackbutton" type="button" value="Ack Alert"></div>';
}
return data;
}
},
],
"language": {
"emptyTable": "No Alerts Available in Table"
}
});
$(document).on("click",".ackbutton",function() {
var currentIndex = $(this).parent().parent().index();
var rowData = alertTable.row( index ).data();
//extract the textbox value
var TextboxValue = $(this).siblings(".ackname").val();
var objToSave = {}; //Create the object as per the requirement
//Add the textbox value also to same object and send to server
objToSave["TextValue"] = TextboxValue;
$.ajax({
url: "url to another page"
data: JSON.stringify({dataForSave : objToSave}),
type: "POST",dataType: "json",
contentType: "application/json; charset=utf-8",
success: function(datas) {
//Your success Code
},
error: function(error) {
alert(error.responseText);
}
});
});
});
Since both the pages are in same project, you can also do it using single ajax, passing all the values to server at once and then calling the other page internally from server and passing in the values using query string.
This is not a running code, rather to give you a basic idea on how to proceed.
Hope this helps :)
