Hiding an element in internet explorer leaves artifacts on the screen (IE 10-11)

We use custom selectbox elements for our page (for reasons), but in one specific place and only with IE (in my case version 10 and 11), there is a problem.
When you open the box and close it, sometimes the browser leaves visual artifacts of that element. If there is a button below the element (in the opened state), then those artifacts are still on top of that button UNTIL you hover over the button, then those artifacts disappear at that place.
I think everyone experienced this behaviour at some point in his life with windows or something else. Sorry if my description isn't perfect.
Here are some screenshots (The red boxes are censored text, sorry):
Open state:
Closed state with artifacts:
Hope my description is accurate, I desperately need a fix for this.
I can't reproduce it on my system, but our QA guy can reproduce it consistently. It also changes depending on the size of the browser. On some sizes it doesn't seem to happen at all. It must be some weird rendering glitch of IE.
I don't think it has anything to do with our custom selectbox element, because it happens only in this specific place and in our old design we experienced it in a different place with a completely different element. At that time I thought it's because the DOM is too complicated for IE, but this page has almost no elements.
EDIT: I Just found out that if I minimize the window and maximize it again, the artifacts disappear, which should confirm that this is a rendering glitch, right?
EDIT 2: Here is the code and css of our custom selectbox
HTML:
<div class="input_selectbox">
<label>Title</label>
<div class="input_selectbox__head" data-placeholder="">
<label>
<input type="hidden" name="id" value="5-10909">
Dummy 1
</label>
</div>
<div class="input_selectbox__body">
<label data-value="" class="">
No Option
</label>
<label id="5-10909" data-value="5-10909" class="input_selectbox__option--selected" data-default="true">
Dummy 1
</label>
<label id="5-12568" data-value="5-12568" class="">

show dynamic array with vue

im newbie with vue so i have a couple of cuestions, im showing a table with some data that i get from a web-service, the thing is , that i dont always get the same amount of data, the data comes in an array, for example like this
var todos = [
{name : "dexter" , color : "orange"},
{name : "jaime", color : "green" },
{name : "stack", color : "yellow" },
{name : "overflow", color : "black" }
]
but as i say, I dont alway's get a response with 2 items in it,
right now i have to declare what item in te array im calling to, and i want to call all the items in the array to show them
var todos = [
{
name: "dexter",
color: "orange"
},
{
name: "jaime",
color: "green"
},
{
name: "stack",
color: "yellow"
},
{
name: "overflow",
color: "black"
}

thanks in advice

You can just assign the web-service-provided data right into your data like
rows: todos

How to pass a parentNode.id as a parameter to an element out of the querySelector

I have these elements created inside a "querySelector('ul'). It's working property.
I want the "blue-Save" button to have the same function as the "yellow-Save".
But the Blue-save button was created in the HTML file, and the Yellow-Save button was created in JavaScript to listen to an event from the "querySelector('ul').
Is there anyway I can just link the Blue-Save to react as if I was clicking in the Yellow-Save?
(I'm sorry if I didn't explain it property or If it seems too confused, this is my first application, It doesn't seems too organized but I'm focused in making things work before dive in 'well developed apps').
Thank You Everyone!

You can add a common class to both blue and yellow buttons, and attach a click event by the class name like below
$(".custom_save_button").on("click", function() {
//your code
});

Since you are creating that button, sharing the same class won't just work as expected, instead use delegated events which allow you to attach events on new elements added to the DOM
Add a common class for both and then add an event listener for that class using event delegation.
For this example Let's suppose you chose the class name: stack_class
//I added this function for you to be able to know if an element has a class
function hasClass( target, className ) {
return new RegExp('(\\s|^)' + className + '(\\s|$)').test(target.className);
}
//you could change body to the closest parent's selector both buttons share
document.querySelector('body').addEventListener('click', function(event) {
var clickedElement = event.target;
if(hasClass(clickedElement, "stack_class")) {
//create your functionality for both buttons here
}
});

If you assign a common class to both buttons, then you can add the same event listener to all buttons that have that class. Here is a simple example:
var saveButton = document.createElement('button');
saveButton.textContent = 'Save';
saveButton.className = 'save-button yellow-button';
body = document.querySelector('body');
body.appendChild(saveButton);
buttons = document.getElementsByClassName('save-button');
for (var i = 0; i < buttons.length; i += 1) {
buttons[i].addEventListener('click', function (event) {
alert('Hello!');
});
}
.yellow-button {
background: #ffff00;
}
.blue-button {
background: #0000ff;
}
<button class="save-button blue-button">Save</button>

Aligning items in a table

I made a "To-List" with two icons that animate on the side. the icon on the right is not in the table. So when animating you can see it moving beyond the table. I can't understand why? any help please?
Thank you!
Hi, here is the fiddle:
https://jsfiddle.net/rggo2tmv/
As you can see, the garbage-bin icon disappears inside the table while the other icon (on the right) continues outside the table.

The icon inside the span element that you animate, doesn't "shrink" with the span as you might expect. It is shown to the right of the 0 width span instead (i.e. it overflows). You have the same effect both on the left and right side which is visible if you change the color of the icons.
Span is an inline element so it normally doesn't have the overflow property but you can use display: inline-block to display it with a given width and height. Use overflow: hidden to hide the icon when squeezing the width of the span element.

Allow Button Click Only Once in Meteor

In my Meteor project, I have two buttons. One button is an upvote button, which adds a point to the score of an entry, while the other is a downvote button, which does the opposite. My site doesn't require login.
How can I restrict it so that any given device can only click either the upvote or downvote button initially, and then if that device decides to change it's vote, it should be able to click only the other button, and so on?

You can use HTML 5 LocalStorage. But it will only work on latest browsers. If you want suppoert for old browsers as well then you might be interested in this question as well. If your user base doesn't use very old browsers then you can do it with LocalStorage like this,
In template's created callback,
Template.yourTemplate.created = function () {
var template = this;
var userVote = null;
if(typeof(Storage) !== "undefined") {
userVote = localStorage.getItem("userVote");
}
template.userVote = new ReactiveVar(userVote); //or you can use Session.setDefault("userVote", userVote)
}
When user clicks on the up or down button
Template.yourTemplate.events({
'click #upButton': function (ev, template) {
localStorage.setItem("userVote", "up");
template.userVote.set("up"); // or Session.set("userVote", "up");
},
'click #downButton': function (ev, template) {
localStorage.setItem("userVote", "down");
template.userVote.set("down"); // or Session.set("userVote", "down");
}
});
Then to disable buttons, you can do something like this in your helpers,
Template.yourTemplate.helpers({
'isUpButtonDisabled': function () {
var template = Template.instance();
var userVote = template.userVote.get(); // or Session.get("userVote");
return userVote === "up";
},
'isDownButtonDisabled': function (ev, template) {
var template = Template.instance();
var userVote = template.userVote.get(); // or Session.get("userVote");
return userVote === "down";
}
});
Update: This answer uses localStorage so that the application can keep track of the user's vote even when user visits the same site at a later date, which was what OP was trying to do, since user can vote without a login.
EDIT: Based on your comment to have different votes for different templates/topics. Assuming you have current topic's id in template's current data. You can do something like this,
In template's created callback,
Template.yourTemplate.created = function () {
var template = this;
template.userVote = new ReactiveVar(null); //or you can use Session.setDefault("userVote", null)
template.autorun(function () {
var data = Template.currentData();
var topicId = data.topicId;
var userVote = null;
if(typeof(Storage) !== "undefined") {
userVote = localStorage.getItem("userVote" + topicId);
}
template.userVote.set(userVote); //or you can use Session.set("userVote", userVote);
});
}
When user clicks on the up or down button
Template.yourTemplate.events({
'click #upButton': function (ev, template) {
var topicId = this.topicId;
localStorage.setItem("userVote" + topicId, "up");
template.userVote.set("up"); // or Session.set("userVote", "up");
},
'click #downButton': function (ev, template) {
var topicId = this.topicId;
localStorage.setItem("userVote" + topicId, "down");
template.userVote.set("down"); // or Session.set("userVote", "down");
}
});
Then to disable buttons, you can do something like this in your helpers,
Template.yourTemplate.helpers({
'isUpButtonDisabled': function () {
var template = Template.instance();
var userVote = template.userVote.get(); // or Session.get("userVote");
return userVote === "up";
},
'isDownButtonDisabled': function (ev, template) {
var template = Template.instance();
var userVote = template.userVote.get(); // or Session.get("userVote");
return userVote === "down";
}
});

It sounds like a regular old radio button should do the trick.
I made some fancier stuff as well, see this CodePen.
Update
Added #4castle's rescind vote function. Nice touch.
Update 2
Per OP's request, the radio buttons are now the arrows.
