Still relatively new to HTML/CSS and currently working on a Live Chat feature for my website utilizing Node.js and MongoDB. I've been able to get the chat to work, but have been stuck on figuring out how to customize a specific aspect of this chat. I'd like to change the font-weight of the username in the chat box (area where all messages are seen) to make the username stand out a bit more compared to the rest of the text in the box. I am confused on how to do so in CSS. I've highlighted (in yellow) the line where the 'Username' is called so I imagine this is the 'class' that I'd need to customize but it tied to the text afterwards if that makes sense...?
Thanks for your help!

message.setAttribute('class', 'chat-message');
message.textContent = data[x].name + ': ' + data[x].message;
//Append
messages.appendChild(message);
messages.insertBefore(message, messages.firstChild);
}
}
});
//Listen for a status
socket.on('status', function(data){
setStatus((typeof data === 'object') ? data.message : data);
if(data.clear === true){
textarea.value = '';
}
});
//Listen for keydown
textarea.addEventListener('keydown', function(event){
var self = this,
name = chatName.value;
if(event.which === 13 && event.shiftKey === false){
socket.emit('input', {
name: name,
message: self.value
});
}
});
}
})();
</script>
</body>
</html>
To add a css selector to the name:
var message = document.createElement('div');
message.setAttribute('class', 'chat-message');
message.textContent = ': ' + data[x].message;
var name=document.createElement('span');
name.setAttribute('class', 'userName');
name.textContent = data[x].name;
message.insertBefore(name, message.firstChild);
Then for css:
.userName{
font-weight: 700;
}
Here's a fiddle for you to see the results: https://jsfiddle.net/p4yfxLd0/

I am trying to show/hide my drag and drop when a document comes to the screen. I used AngularJS and it worked. However, it does not work in all modules. Although I same always the same code but from other modules :
working code :
<div ngf-drop ngf-select ng-model="files" ngf-multiple="true" ngf-allow-dir="true" ng-show="dropIsVisible === true">
<div class="drop-area-full-page">
<div class="drop-area-full-page__graphic"></div>
<div class="drop-area-full-page__info" id="drop-area-full-page__info" ng-bind-html="dropText"></div>
</div>
</div>
And in AngularJS:
$window.addEventListener("dragenter", function (e) {
if (isFile(e)) {
lastTarget = e.target;
$scope.dropIsVisible = true;
name = getName($scope, getParent());
$scope.dropText =
"<b> Dokument ablegen zu </b>" + "<b>" + name+ "</b>";
}
});
$window.addEventListener("dragleave", function (e) {
e.preventDefault();
if (e.target === document || e.target === lastTarget) {
$scope.dropIsVisible = false;
}
});
$window.addEventListener("dragover", function (e) {
e.preventDefault();
$scope.dropIsVisible = true;
});
function getParent() {
return {
entityName: $stateParams.entity,
id: $scope.parentId
};
}
$window.addEventListener("drop", function (e) {
e.preventDefault();
$scope.dropIsVisible = true;
var qs = e.dataTransfer.files[0].name;
var parent = getParent();
DokumentUploadMixin.Prepare(qs, e.dataTransfer.files[0], $scope, parent, projection, qs);
//$window.location.href = routeUtils.getCreateDokumentUrl("Dokument", getParent(), projection, qs);
});
};
And the code that is not working:
<div ngf-drop ngf-select ng-model="files" ngf-multiple="true" ngf-allow-dir="true" ng-show="dropIsVisible === true">
<div class="drop-area-full-page">
<div class="drop-area-full-page__graphic"></div>
<div class="drop-area-full-page__info" id="drop-area-full-page__info" ng-bind-html="dropText"></div>
</div>
</div>
Which is the same ....
Are there any tips that I should do for making it work in all modules?
the answer was that i showld apply the scope to event listener cause i added custom event listeners, which are not tracked by Angularjs. In order to make it work applying inside addEventListener callback with $scope.$apply to tell angular update the model.
$window.addEventListener("dragenter", function (e) {
$scope.$apply(function() {
if (isFile(e)) {
lastTarget = e.target;
$scope.dropIsVisible = true;
name = getName($scope, getParent());
$scope.dropText =
"<b> Dokument ablegen zu </b>" + "<b>" + name+ "</b>";
}
});
});
$window.addEventListener("dragleave", function (e) {
$scope.$apply(function() {
e.preventDefault();
if (e.target === document || e.target === lastTarget) {
$scope.dropIsVisible = false;
}
});
});
$window.addEventListener("dragover", function (e) {
$scope.$apply(function() {
e.preventDefault();
$scope.dropIsVisible = true;
});
});
I used the the information from the link (here) and got the following code, which helps me to record a video with my webcam. The code allows me to record a video and makes it available to download. However, I want to save the recorded video automatically to a local folder. How can I do that?

You will have to use the recorder.getBlob() method to get the actual blob of the video file, then send it to your server which will then save it to a file :
javascript:
stopRecordingVideo.onclick = function() {
this.disabled = true;
recordVideo.disabled = false;
if (recorder)
recorder.stopRecording(function(url) {
video.src = url;
video.play();
var recordedBlob = recorder.getBlob();
var formData = new FormData();
formData.append("videofile", recordedBlob);
var xhr = new XMLHttpRequest();
xhr.open("POST", "savevideofile.php");
xhr.send(formData);
document.getElementById('video-url-preview').innerHTML = '<a href="' + url + '>Recorded Video URL</a>';
});
};
savevideofile.php:
<?php
if($_FILES['videofile']){
$my_file = $_FILES['videofile'];
$my_blob = file_get_contents($my_file['tmp_name']);
file_put_contents('/path/to/your/file.webm', $my_blob);
}
?>
After looking at the source code of the web page you linked, the 'url' from your callback for stopRecording should be a downloadable URL.
All you'd have to do would be to take that URL and use it in an anchor with HTML5 download attribute, like so:
recorder.stopRecording(function(url) {
video.src = url;
video.play();
document.getElementById('video-url-preview').innerHTML = 'Recorded Video URL';
});
I am trying to perform acceptance tests for my website using Codeception, and I am experiencing a strange error due to a reset button on the form I am testing. Basically, my test for clicking on 'Save' works only if either the reset button on my form is AFTER the Save button, or if the reset button is left off the form altogether. If the reset button is inserted in the form before the save button, Codeception throws an Unreachable field "reset" error. Here is my Codeception code:
<?php
$I = new WebGuy($scenario);
$I->wantTo('find an employee in the database');
$I->amOnPage('/employees/find/');
$I->fillField('employeeLookup[first_name]', 'Sergi');
$I->click('Save', '#employeeLookup_save');
$I->see('Based on your search for Sergi, the following employees were found:');
$I->see('Remmele');
$I->see('Feb 28 1992');
And here is my HTML (much of it being generated from Symfony2):
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

</body>
</html>
Finally, here is the relevant output of the error message from Codeception:
1) Failed to find an employee in the database in FindEmployeeCept.php
Sorry, I couldn't click "Save","#employeeLookup_save":
Behat\Mink\Exception\ElementException: Exception thrown by ((//html/descendant-or-self::*[#id = 'employeeLookup_save'])[1]/.//input[./#type = 'submit' or ./#type = 'image' or ./#type = 'button'][(((./#id = 'Save' or ./#name = 'Save') or contains(./#value, 'Save')) or contains(./#title, 'Save'))] | .//input[./#type = 'image'][contains(./#alt, 'Save')] | .//button[((((./#id = 'Save' or ./#name = 'Save') or contains(./#value, 'Save')) or contains(normalize-space(string(.)), 'Save')) or contains(./#title, 'Save'))] | .//input[./#type = 'image'][contains(./#alt, 'Save')] | .//*[./#role = 'button'][(((./#id = 'Save' or ./#name = 'Save') or contains(./#value, 'Save')) or contains(./#title, 'Save') or contains(normalize-space(string(.)), 'Save'))])[1]
Unreachable field "reset"
Again, if the reset button is rendered after the save button in the HTML, the acceptance tests pass just fine. Also, if the reset button is left off of the form entirely, the acceptance test passes as well. Does anyone have any idea what is causing this?

I did not find your declaration of the function "createCookie". It seems you copied the code and forgot to copy the function.
Btw: "xxx is not defined" always means the variable/function does not exist ..
I have a textarea with default text 'write comment...'. when a user updates the textarea and clicks 'add comment' Google chrome does not get the new text. heres my code;

any help much appreciated.
I believe you should be using val() and not html() on a textarea.
On a side note, for Chrome use the placeholder attribute on the textarea. You won't need a lot of this code.
<textarea placeholder="Write a comment"></textarea>
