Hi,
I load page-specific javascript files as follows.
<script suppress-error="BL9992" src="@KTTheme.GetAssetPath("zcustom/js/datatable.init.js")"></script>protected override async Task OnAfterRenderAsync(bool firstRender)
{
if (firstRender)
{
await js.InvokeAsync<IJSObjectReference>("TestDataTablesAdd", "#kt_datatable_example"); //line 473
}
}Javascript File:
function TestDataTablesAdd(tableName/*, jsonData, jsonColumns*/) {
$(document).ready(function () {
var table = document.querySelector(tableName);
$(table).DataTable({
//"data": jsonData,
//"columns": jsonColumns,
"fixedHeader": {
"header": true,
"headerOffset": 73
},
columnDefs: [
{ orderable: false, targets: 0 },
{ orderable: false, targets: 1 },
{ "visible": false, "targets": 1 }
],
order: [[2, "asc"]],
"scrollX": true,
//"responsive": true,
"info": false,
"pageLength": 10,
"select": true,
"select": {
style: "multi",
selector: "td:first-child input[type="checkbox"]",
className: "row-selected"
}
});
});
}
function TestDataTablesRemove(tableName) {
$(document).ready(function () {
var table = document.querySelector(tableName);
$(table).DataTable().destroy();
// Removes the datatable wrapper from the dom.
var elem = document.querySelector(table + "_wrapper");
elem.parentNode.removeChild(elem);
});
}But when I call the page it gives an error like this

Hi,
Thank you for reaching out to us.
You can try adding your functions to the window scope like this:
window.TestDataTablesAdd = TestDataTablesAdd;
window.TestDataTablesRemove = TestDataTablesRemove;Additionally, ensure that your JavaScript file is correctly loaded on your page.
