I am using mpld3 to convert Matplotlib plots into D3 web embedable graphics. I am then using a JS library written on top of MathJax called svg_mathjax2.js (https://github.com/ichuang/svg_mathjax2) to apply Tex conversions.
The error I get is at this line of svg_mathjax2.js:
var svgmath = mathjaxdiv.getElementsByClassName('MathJax_SVG')
[0].getElementsByTagName('svg')[0];
It gives the error:
Uncaught TypeError: Cannot read property 'getElementsByTagName' of undefined
Everything works fine the first time I load Mathjax, it converts the text appropriately. However, any additional calls (via AJAX) don't work.
I've posted an issue on the github page, but have not heard back. I'm not sure if this is an issue with svg_mathjax2 or mpld3. Perhaps someone familiar with MathJax can help out?
Never mind, I figured this out. It was specific to the svg_mathjax2.js.
I solved it by activating this block of code:
if (1) {
MathJax.Hub.Register.StartupHook("End Typeset", function () {
forEach(items, function (x) {
});
// remove the temporary items
var mathbucket = document.getElementById('mathjax_svg_bucket');
mathbucket.parentNode.removeChild(mathbucket);
});
}
}

I'm using FooTables and trying to implement the export table functionality. I've looked at the little bit of documentation they have and I think I'm implementing it correctly, however even when I apply a filter on the table the export still returns all rows. I'm wondering if I'm missing something or not quite implementing it correctly.
$('#exportFooTable').on('click', function () {
var table = FooTable.get('#customerItems');
var csv = new FooTable.Export(table).csv(true);
// do stuff;
});
Initially I thought it was due to pagination but the export was returning all rows. I'm at a loss and was thinking of just implementing my own export at this point, but I figured I would see if anyone has any insight before I go down that road.
Update:
I doing some further reading I guess I should be calling this as such:
$('#exportFooTable').on('click', function (e) {
var csv = FooTable.get('#customerItems').toCSV(true);
// do stuff;
});
However this gives me a type error stating that toCSV is not a function. Does anyone know why this error is being thrown and how to resolve it?
The following code does work. I thought I had the latest version of FooTable standalone since I used the download link from their website found here: https://fooplugins.github.io/FooTable/docs/getting-started.html#download
$('#exportFooTable').on('click', function (e) {
var csv = FooTable.get('#customerItems').toCSV(true);
// do stuff;
});
However this is version 3.1.5 in which there is a bug that causes the export to not work. If you want to be sure you have the latest version (3.1.6) you should go to the following link, find the appropriate version (Bootstrap, Standalone or Individual Components) and download the 3.1.6 zip file for that version: https://github.com/fooplugins/FooTable/tree/V3/releases
I have recently taken an interest into unity, and as I guide a chose a playlist from youtube. I have installed the
Unity 5.6.4
16 Oct, 2017
version as well.
Now, I encounter an error when I try to add a script to an object.
In the tutorial:
here
, this happens from 11:40 to 13:40.
Basically, as a summary, he is writing a script in js and then attaches it to an object. Now, I have followed the exact steps as him, but it does not work for me.
I write the same script as him, in JS:
then add the script to the object. But then, on the object, I should get a target option, like he does:
However, I don't get this option on my object:
The error I get in the console is this:
Assets/Scripts/PickUp.js(1,386): BCE0044: unexpected char: 0xFEFF.
And this is the actual script:
var target : Transform;
function Update () { }
function OnMouseDown ()
{
this.transform.position = target.position;
this.transform.parent = GameObject.Find("FPSController").transform;
this.transform.parent = GameObject.Find("FirstPersonCharacter").transform;
}
function OnMouseUp ()
{
this.transform.parent = GameObject.Find ("FPSController").transform;
this.transform.parent = null;
}
Now, I've heard that it is not the most efficient, but at this point, I don't really care about that, I just want it to work.
Try to save your script using UTF8 - no BOM (ByteOrderMark). If that does not help, save as Ansi and try that - or read up what unity wants :)

This UTF-8 as default in Unity3D new script? was not solved unfortunately.
I am currently working on a project where we need to generate some SVG based on some input data. Currently all this SVG generation is implemented in javascript using the d3 library. Note that my goal is to be able to reuse this logic and not implement it all over.
My problem is that I would like to be able to call this javascript from C#.
I have tried using PhantomJS and I am able to generate the SVG but I am not satisfied because
Each time I want to call the javascript it starts a new process and I
have noticed that it uses a lot of memory (In my case I saw 100 mb
which is too much in my case)
It seems a little unstable. I have
had some cases where the process just hangs
Development (On the javascript side) is pretty frustrating because it is hard to debug
Because I was not satisfied with PhantomJS I have also tried using jint and this seems really nice to work with. Unfortunately I haven't quite managed to get a working example up and running. Currently I am using AngleSharp to supply the DOM so that D3 has a place to write its data. This gives me the following example:
static void TestJint()
{
//We require a custom configuration with JavaScript and CSS
var config = Configuration.Default.WithJavaScript().WithCss();
//Let's create a new parser using this configuration
var parser = new HtmlParser(config);
//This is our sample source, we will do some DOM manipulation
var source = "<!doctype html> <html><head></head> <body> </body></html>";
var document = parser.Parse(source);
var jintEngine = new Engine();
jintEngine.SetValue("document", document.Implementation);
jintEngine = jintEngine.Execute(File.ReadAllText("d3.min.js"));
jintEngine = jintEngine.Execute("function testFunc() { d3.select(\"body\").append(\"span\").text(\"Hello, world!\"); return 42;}");
var res = jintEngine.Invoke("testFunc").ToObject();
}
The problem is that the line var res = jintEngine.Invoke("testFunc").ToObject(); throws an exception.
Exception screenshot
If I try replacing the line
jintEngine = jintEngine.Execute("function testFunc() { d3.select(\"body\").append(\"span\").text(\"Hello, world!\"); return 42;}");
with
jintEngine = jintEngine.Execute("function testFunc() { d3.select(\"body\"); return 42;}");
then the function is able to run without any exceptions. By playing a little with the logic I have concluded that it is the .append(\"span\") that causes the exception.
I am a little stuck so I was hoping that someone might have an idea that could point me in the right direction.
I have figured out the problems.
1) The document returned by parser.Parse(source); does not implement the function createElementNS which d3 uses. I solved this by using a wrapper that delegates the call.
2) d3 uses the variable ownerDocument which I havn't set. So I also had to add the following
jintEngine.SetValue("ownerDocument", new MyDocumentWrapper(document));
Note that this doesn't make the entire d3 library work. I have also noticed some problems with d3.geopath() but with these fixes I am able to execute my initial example.
i build my game using phaser.2.4.3.min.js and phaser.2.2.2.box2d.min.js
When trying to change states this error is being raised TypeError: R[o5R.F6s] is not a function and i can't seem to figure out the problem
PS : i took The source code of box2d plugin from the example folder in phaser , and i did not purchase the full plugin yet i was just testing it .
is there anyway to fix this issue ?
here is the game code : http://jsfiddle.net/fbdtq1tg/5/
and here where the error is raised :
SetGameOver: function () {
this.game.state.start("TheGame");
}
The error seems clear: the script is trying to execute a function, but this variable isn't a function.
What happens: box2d.m_gravity = box2d.clone(); but R[o5R.F6s]() is the string "clone" and not a function. R = box2d, so the the script is trying to execute a function(R[o5R.F6s](). o5R is an object with a lot of functions in it but the requested F6s is a string("clone").
So, I did some research why box2d.b2world = function(gravity){...this.m_gravity = gravity.Clone();.. } and it seems to be a bug.

Just getting started with Raphael.
Now I'm finding that paper.remove() is generating a script error:
"SCRIPT5009: 'removed' is undefined
Is this a script bug?
My variable paper is initialized thus:
var paper = new Raphael(document.getElementById('canvas_container'), 500, 500);
My HTML body has:
<div id="canvas_container"></div>
This is more info --
I am using Raphael 2.0 which I just downloaded again. Running IE9. Following is the Raphael JS function that is highlighted as the problem:
R.prototype.remove = function () {
eve("remove", this);
this.canvas.parentNode && this.canvas.parentNode.removeChild(this.canvas);
for (var i in this) {
this[i] = removed(i);
}
};
the line ... removed(i) is highlighted --> SCRIPT5009: 'removed' is undefined
BTW I am new to this forum. Is there a way to respond to a thread other than "Answer Your Question"?
I've run across this a couple of times. The line 4443 method as suggested by sudoko-san does work in browsers but not backwards compatible with IE-7 & 8 (the whole point of using raphael).
Another work around is to implement the following code in your javascript:
try{
paper.remove();
}
catch (error) {
// this catches the error and allows you to proceed along nicely
}
That's it!
I don't know if you've supplied enough information to answer this question.
What version of Raphael are you using?
On what browser?
Is it being loaded up correctly - can you create any Raphael objects?
If all you're doing is deleting the paper, see the fiddle below.
JSFiddle
It seems to work fine for me with Raphael 1.5.2
Hope that helps (even slightly).
