The following has some SVG squares that march upwards once per second. In Google Chrome it looks fine. In Firefox, the squares shift right and left by about 1 pixel which is not what I intended.
Can anyone help figure out why?
I'm sorry this code snippet is not simpler; this is about as basic as I could go from a much longer file in which I removed all the unrelated aspects.

Looks like floating-point rounding errors strike again. I changed to shape-rendering: crispEdges; and then rounded to an integer translate in one of the root elements and that seems to fix most of it (still a little residual y-axis shift).
was:
var x1 = L*0.5+5;
var wheel = svg.append('g')
.attr('id','wheel')
.attr('transform','translate('+x1+',0)');
changed to:
var x1 = Math.round(L*0.5+5);
var wheel = svg.append('g')
.attr('id','wheel')
.attr('transform','translate('+x1+',0)');

I am using a directive to show the number count effect for my dashboard when i used the directive for the h3 i am getting the result as NaN. when i remove the directive from the h3 i am getting the correct output.
When i looked into the directive i can the the value is get from element which shows the value as NaN. can anyone tell me what is wrong in the code?
Output with directive:
<h3 animate-numbers="" class="ng-binding">NaN</h3>
Html:
<h3 animate-numbers>{{vm.dashboard.no_of_applications}}</h3>
Controller:
vm.dashboard = {

Problem: I am trying to use ng-bind-html but I am getting the following errors on the console:
The following is the controller where I am calling ngSanitize:
and using the following file:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-sanitize.js"></script>
In my form, I do the following to use ng-bind-html. So when I try to see my results, it is still rendering the &rather then &:
<div ng-bind-html="e.Specialty"></div>
and the following is what occurs in the Specialty:
Any help would be appreciated.

When you use ng-bind-html, AngularJS sometimes consider some contents as unsafe (as your case), so you need to use the $sce service in order to "mark" this content as safe (to be used) like this:
$sce.trustAsHtml("CLINICAL & SOCIAL"); (See demo below)
From $sanitize
The input is sanitized by parsing the HTML into tokens. All safe
tokens (from a whitelist) are then serialized back to properly escaped
html string. This means that no unsafe input can make it into the
returned string.
In this case the "unsafe" part is &
angular
.module('app', [])
.controller('ctrl', ctrl);
function ctrl($scope, $sce) {
$scope.Specialty = $sce.trustAsHtml("CLINICAL & SOCIAL");
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-sanitize.js"></script>

This used to work in Cesium v1.26. I have just encountered this same issue with the current Cesium v1.34 and have logged a bug. The labels will appear if you disable clustering.
I am trying to access webcam from jquery webcam API. The sample given below works fine in IE9, Firefox, but unfortunately does not work in Chrome v35. It shows the webcam activated but when I click the "Take Picture" button, it gives me a javascript error saying that webcam.capture is undefined. In the code below, the webcam object does not have any function called capture() in chrome; but its found for Firefox and IE9.
Please help me out!!

I think I found the answer. I was initially trying to run the code from a folder location on my system. But when I deployed the same code to a local web application running on tomcat (http://<>/webcam/webcam.html), it started working in chrome!! I was anyhow going to deploy the code tomorrow on a remote server but had no idea that the webcam APIs would be inaccessible from the system if the application is not running on a server. Quite strange, but this saved me!!
I'm a noob and trying to implement a search method for a diagram.
The diagram is a chord diagram and was mostly adapted from here:
http://bl.ocks.org/mbostock/1044242
And the search function was taken from here:
http://mbostock.github.io/protovis/ex/treemap.html
My problem is that when it reads my file it interprets the text as: [object SVGTextElement] and so the only hit I have for my search is if I search [object SVGTextElement].
This is my entire code:

The input is bla3.json and looks like this:
[{"name":"A.Patient Intake","imports":["E.Name","C.injury","E.DOB","E.Email","Progress","B.Obtain Brief Medical History","Perform Physical Exam","Perform Subjective Patient Evaluation"]},
{"name":"C.injury","imports":[]},
{"name":"E.Name","imports":[]},
{"name":"E.Email","imports":[]},
...
I didn't put the whole thing but it shouldn't matter...
My purpose is of course to have a search function that I could type, for example, "Patient Intake" and it will highlight that chord (or just the name):
Any ideas of how to go about this?
I would approach this in a completely different way to what you're currently doing. I would filter the data based on the query (not the DOM elements) and then use D3's data matching to determine what to highlight. In code, this would look something like this.
function update(query) {
if (query != re) {
re = new RegExp(query, "i");
var matching = classes.filter(function(d) { return d.name.match(re); });
d3.selectAll("text.node").data(matching, function(d) { return d.name; })
// do something with the nodes
// can be source or target in links, so we use a different method here
links.filter(function(d) {
var ret = false;
matching.forEach(function(e) {
ret = ret || e.name == d.source.name || e.name == d.target.name;
});
return ret;
})
// do something with the links
}
}
