Just struggling to get the Attach addon working. The main xterm (4.4.0) comes up fine, but the Chrome browser Javascript console reports 'Uncaught TypeError: AttachAddon is not a constructor' when I try to reference the addon. The webserver is golang/echo, and I pull in the xterm.js and xterm-addon-attach.js from the packages as follows:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
<script src="xterm-addon-attach.js"></script>
</head>
<body>
<div id="terminal"></div>
<script>
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://example.net:8080/ws')
const attachAddon = new AttachAddon(ws);
term.loadAddon(attachAddon);
</script>
</body>
</html>
Can anyone help to point out what I've done wrong?
Also the examples in the docs where I took this from doesn't have the term.open() call, so how would the Terminal instance know what element to attach to? Eg at https://github.com/xtermjs/xterm.js/tree/master/addons/xterm-addon-attach
Many thanks in advance
Andy
Update:
I changed the HTML to include the import statements, as follows:
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
</head>
<body>
<div id="terminal"></div>
<script type="module">
import { AttachAddon } from "./xterm-addon-attach.js";
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://boundstone.dynamic-dns.net:8080/ws');
const attachAddon = new AttachAddon(ws);
term.loadAddon(attachAddon);
</script>
</body>
</html>
but the Chrome console now reports: "The requested module './xterm-addon-attach.js' does not provide an export named 'AttachAddon'". The webserver serves the script with content type application/javascript, and the Chrome console recognises the structure of the AttachAddon as a Webpack it seems.
I'm afraid I'm not familiar as I clearly should be with JS modules. The web server for my project is not (and can't be) Node, but does that make a difference?
Many thanks in advance

This is what worked for me. The only thing you have to do is use AttachAddon twice as shown below using the OP's example. That's the only trick to getting it working. I am also using the fit addon and it was the same thing with that.
<!doctype html>
<html>
<head>
<link rel="stylesheet" href="xterm.css" />
<script src="xterm.js"></script>
</head>
<body>
<div id="terminal"></div>
<script>
var term = new window.Terminal();
term.open(document.getElementById('terminal'));
ws = new WebSocket('ws://boundstone.dynamic-dns.net:8080/ws');
const attachAddon = new AttachAddon.AttachAddon(ws);
term.loadAddon(attachAddon);
</script>
</body>
I am trying to work with jQuery's Datatable JS for my project from this link.
I downloaded the complete library from the same source. All the examples given in the package seem to work fine, but when I try to incorporate them in my WebForms,the CSS,JS do not work at all.
Here is what I have done :
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<link href="css/jquery.dataTables.css" rel="stylesheet" type="text/css" />
</head>
<body>
<form id="form1" runat="server">
<div>
<table id="myTable" class="display" cellspacing="0" width="100%">
<thead>
<tr>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Age</th>
<th>Start date</th>
<th>Salary</th>
</tr>
</thead>
<tfoot>
<tr>
<th>Name</th>
<th>Position</th>
<th>Office</th>
<th>Age</th>
<th>Start date</th>
<th>Salary</th>
</tr>
</tfoot>
<tbody>
<!-- table body -->
</tbody>
</table>
</div>
<script src="js/jquery.dataTables.js" type="text/javascript"></script>
<script src="js/jquery.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#myTable').DataTable();
});
</script>
</form>
</body>
</html>
My file structure for the JS and CSS in my Solution looks as follows :
I have added all the necessary JS and CSS references as shown in the manual. Still the rendering isn't as expected. There is no CSS and even the JS doesn't work.
Also in the console i get the following errors:
ReferenceError: jQuery is not defined
TypeError: $(...).DataTable is not a function
I have still not bound any dynamic data here (like within a repeater or so) still it is not working.
Can someone please guide me in the right direction for this problem ?
CAUSE
There could be multiple reasons for this error.
jQuery DataTables library is missing.
jQuery library is loaded after jQuery DataTables.
Multiple versions of jQuery library is loaded.
SOLUTION
Include only one version of jQuery library version 1.7 or newer before jQuery DataTables.
For example:
<script src="js/jquery.min.js" type="text/javascript"></script>
<script src="js/jquery.dataTables.min.js" type="text/javascript"></script>
See jQuery DataTables: Common JavaScript console errors for more information on this and other common console errors.
This worked for me. But make sure to load the jquery.js before the preferred dataTable.js file. Cheers!
<script type="text/javascript" src="~/Scripts/jquery.js"></script>
<script type="text/javascript" src="~/Scripts/data-table/jquery.dataTables.js"></script>
<script>$(document).ready(function () {
$.noConflict();
var table = $('# your selector').DataTable();
});</script>
I got this error because I found out that I referenced jQuery twice.
The first time: on the master page (_Layout.cshtml) in ASP.NET MVC, and then again on one current page so I commented out the one on the master page.
If you are using ASP.NET MVC this snippet could help you
#*#Scripts.Render("~/bundles/jquery")*#//comment this line
#Scripts.Render("~/bundles/bootstrap")
#RenderSection("scripts", required: false)
and in the current page I added these lines
<script src="~/scripts/jquery-1.10.2.js"></script>
<!-- #region datatables files -->
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.12/css/jquery.dataTables.min.css" />
<script src="//cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
<!-- #endregion -->
Hope this help you even if don't use ASP.NET MVC
if some reason two versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
Sometimes it could be issue with older version (or not stable) of JQuery files
Solution use $.noConflict();
<script src="js/jquery.js" type="text/javascript"></script>
<script src="js/jquery.dataTables.js" type="text/javascript"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
$('#myTable').DataTable();
});
// Code that uses other library's $ can follow here.
</script>
Here is the complete set of JS and CSS required for the export table plugin to work perfectly.
Hope it will save your time
<!--Import jQuery before export.js-->
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>

Result :-
Same error occurs when working with DataTables in a Laravel project. Even if the following solutions are tried, the error still remains:
making sure jQuery is included
include jQuery before including the DataTables
making sure only one version of jQuery is added
In order to remove the error, after making sure the above conditions are fulfilled, add "defer" to the tag which includes the DataTables. For example,
<script src="https://cdn.datatables.net/1.10.23/js/jquery.dataTables.min.js" defer></script>
There can be two reasons for that error:
First
You are loding jQuery.DataTables.js before jquery.js so for that :-
You need to load jQuery.js before you load jQuery.DataTables.js
Second
You are using two versions of jQuery.js on the same page so for that :-
Try to use the higher version and make sure both links have same version of jQuery
I tried many things but my solution was adding "defer" after html script that you included datatables.
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.25/js/jquery.dataTables.js" defer></script>
Honestly, this took hours to get this fixed. Finally only one thing worked a reconfirmation to solution provided by "Basheer AL-MOMANI". Which is just putting statement
#RenderSection("scripts", required: false)
within _Layout.cshtml file after all <script></script> elements and also commenting the jquery script in the same file. Secondly, I had to add
$.noConflict();
within jquery function call at another *.cshtml file as:
$(document).readyfunction () {
$.noConflict();
$("#example1").DataTable();
$('#example2').DataTable({
"paging": true,
"lengthChange": false,
"searching": false,
"ordering": true,
"info": true,
"autoWidth": false,
});
});
I know its late

This could also happen if you don't add $('#myTable').DataTable(); inside the document.ready
So instead of this
$('#myTable').DataTable();
Try This
$(document).ready(function() {
$('#myTable').DataTable();
});
I have Added defer to the data table jquery library reference. Now it is working for me.
<script src="~/Scripts/jquery.dataTables.min.js" defer></script>
I ran into this error also. For whatever reason I had originally coded
var table = $('#myTable').DataTable({
"paging": false,
"order": [[ 4, "asc" ]]
});
This would not throw the error sometimes and other times it would. By changing code to
$('#myTable').DataTable({
"paging": false,
"order": [[ 4, "asc" ]]
});
Error appears to have stopped
In my case the solution was to delete cookies from the browser.
Having the same issue in Flask, I had already a template that loaded JQuery, Popper and Bootstrap. I was extending that template into other template that I was using as a base to load the page that had the table.
For some reason in Flask apparently the files in the outer template load before the files in the tables above in the hierarchy (the ones you are extending) so JQuery was loading before the DataTables files causing the issue.
I had to create another template where I run all my imports of JS CDNs in the same place, that solved the issue.
Sometimes it happens that the script (initializing of datatable) is embedded in a general page template, so if one of the pages that actually does not have any table and you did not import the jquery related files for datatable, you face this error, since the general initialization still is looking for that. (This was in my case)
Solution: Is to wrap the initialization of datatable inside a codition that check presence of the library before that:
Here is practical example of it.
if (typeof jQuery.fn.DataTable != "undefined"){
$('#accordionExample table').DataTable( {
"pageLength": 5,
"info": false,
"order": [[ 1, "desc" ]]
} );
}
This may also happen if you write Datatable instead of DataTable. (DataTable T must be capital). this is a beginner's mistake.
$(document).ready(function() {
$('#category-table').DataTable({
// Your Code
});
if you are sure that you aligned your scripts as described above, please make sure you DataTable word case is correct.
Before
$(document).ready(function() {
$('#myTable').Datatable();
});
After
$(document).ready(function() {
$('#myTable').DataTable();
});
small t is creating problem, when I changed this t to T it worked like a charm.
I'm a newbie to reactjs and trying to test a very basic component, however it seems all my struggle is futile because its not showing up in the browser.
I'm using asp.net MVC 5 app and I've been following along this tutorial https://reactjs.net/getting-started/tutorial_aspnet4.html as the tutorial states you need to add React.Web.Mvc4 Nuget package which have some dependencies.
My simple React component (SimpleComponent.jsx)
var ComponentBox = React.createClass({
render: function() {
return (<div style="background-color:antiquewhite">Hello World ReactJs Component!</div>);
}
});
ReactDOM.render(
<ComponentBox />,
document.getElementById('reactDiv')
);
and my razor view is pretty simple
#{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>

</head>
<body>
<div id="reactDiv"></div>
<script src="#Url.Content("~/Scripts/SimpleComponent.jsx")"></script>
</body>
</html>
Did I miss something?
The Solution for my problem was to replace the style element in my jsx file as following
var ComponentBox = React.createClass({
render: function () {
return (<div style={{background:'antiquewhite'}}>Hello World ReactJs Component!</div>);
}
});
Based on react docs "using the style attribute as the primary means of styling elements is generally not recommended"
by using javascript object to store the style as properties and I hope this'll help someone.
I have code written to autocomplete a text input box from a mysql database. I am currently in the process of mitigating the setup to jQuery Mobile but I am having substantial issues finding out how to write a modified autocomplete. My original html is below (heavily simplified)
<html>
<head>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
</head>
<script>
$(function() {
$( "#get_ingredient_1" ).autocomplete({source: 'search.php'});
});
</script>
<div class="ui-widget">
<input id="get_ingredient_1" name="ingredient_type" style = "width:200px">
</div>
</html>
the search.php is shown below.
<?php
//database configuration
include("db_connect.php");
//get search term
$searchTerm = $_GET['term'];
//get matched data from skills table
$category_query = mysqli_query($dbconnection, "SELECT DISTINCT ingredient FROM ingredients WHERE ingredient LIKE '%".$searchTerm."%' ORDER BY ingredient ASC");
//while ($row = $query->fetch_assoc()) {
while($row = mysqli_fetch_assoc($category_query)){
$data[] = $row['ingredient'];
}
//return json data
echo json_encode($data);
?>
this outputs in the format:
["Adzuki beans","Alfalfa","Allspice","Almond meal"]
ive tried to comment it accordingly. Essentially this generates a text input bot and when you start typing will try and guess what ingredient you are wanting.
unfortunatly when I alter the jquery files to:
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
It no longer autocompletes. Ive read through dozens of examples but I cant find a basic 1 input autocomplete option that I can adapt.
Can anyone shed some light on how to alter this short piece of code to autocomplete, so I can study and adapt it to its full functionality.
Ive looked at all the jquery-mobile examples but have found them lacking in the details I need here, specifically the "remote listview" as it has to populate from a file generated from a mysql source like the search.php shown above.
hope someone can help translate this to jquery mobile use.
I am having trouble with using OpenLayers in Gmaps4Rails (Gem version 1.5.2.) When I click on a marker I would like to show the typical callout (Infobox). Unfortunately I get the following JavaScript error:
this.serviceObject is undefined
Firebug calls the line 195 of the file "gmaps4rails.openlayers.js" responsable:
return this.serviceObject.addPopup(popup);
If I use Google Maps as API provider instead, everything works fine. Showing and hiding the infobox works nicely. This is why I assume that the error must be somewhere in "gmaps4rails.openlayers.js"
I tried on the latest FF and Chrome on Mac.
For reproducing the error in a reduced example, I created a simple HTML page in the public folder of my Rails 3.2 app and directly linked the needed JS and CSS files. To create the HTML page I copied the HTML code of my broken Rails app and reduced it.

};
Gmaps.oldOnload = window.onload;
window.onload = function() {
Gmaps.triggerOldOnload();
Gmaps.loadMaps();
};
</script>
</body>
</html>
Unfortunately I could not find a working example of a successful Gmap4Rails–Openlayers integration on the web. Am I missing a mandatory parameter?
Thanks in advance.
It's a bug.
Replace:
return this.serviceObject.addPopup(popup);
with:
return this.map.addPopup(popup);
I'll push a fix soon, thanks and +1
