Event overriding RactiveJS - ractivejs

I find myself in a little bit of trouble because triggering an event on a element will also fire the event binded to its parent element like the following.
var template = new Ractive({
el: 'wrapper',
template: '<div on-click="open">OPEN<div on-click="close">CLOSE</div></div>'
});
template.on({
open: function(e) {
alert('opening');
},
close: function() {
alert('closing');
}
});
div > div {
display: inline-block;
padding: 10px;
background: rgba(0, 0, 0, .3);
padding: 10px 10px 10px 50px;
cursor: pointer
}
<script src="https://cdn.ractivejs.org/latest/ractive.js"></script>
<div id="wrapper"></div>

You can stop a DOM event bubbling by calling its stopPropagation method. The event argument passed to Ractive event handlers stores the original DOM event as event.original - so you can do it like so:
var template = new Ractive({
el: 'wrapper',
template: '<div on-click="open">OPEN<div on-click="close">CLOSE</div></div>'
});
template.on({
open: function(e) {
alert('opening');
},
close: function(e) {
alert('closing');
e.original.stopPropagation();
}
});
div > div {
display: inline-block;
padding: 10px;
background: rgba(0, 0, 0, .3);
padding: 10px 10px 10px 50px;
cursor: pointer
}
<script src="https://cdn.ractivejs.org/latest/ractive.js"></script>
<div id="wrapper"></div>

Hide the dropdown list when clicking or scrolling on outside

I want to close my dropdown list after clicking or scrolling outside the pane. Still the dropdown box is open all time when we scrolling outside the dropdown box.. This is my code..

How can I hide the dropdown box when scrolling outside?
In few words: you need to add event listener when dropdown is open and make ref on your dropdown to avoid click event on your dropdown, but fire it on clicking somewhere else (and remove eventlistener here). Also you can listen for scrolling events. This is implementation example:
import React, {Component} from 'react';
import { CSSTransition } from 'react-transition-group';
class Dropdown extends Component {
constructor(props) {
super(props);
this.setWrapperRef = this.setWrapperRef.bind(this);
this.handleClickOutside = this.handleClickOutside.bind(this);
};
setWrapperRef(node) {
this.wrapperRef = node;
};
handleClickOutside(e) {
e.stopPropagation();
if (this.wrapperRef && !this.wrapperRef.contains(e.target) && this.props.isOpen){
this.props.onClose();
}
};
componentDidUpdate(){
if(this.props.isOpen){
document.addEventListener('mousedown', this.handleClickOutside);
} else {
document.removeEventListener('mousedown', this.handleClickOutside);
}
}
render(){
return (
<div className={"dropdown " + (this.props.isOpen ? "show" : "hide")} ref={this.setWrapperRef}>
<CSSTransition in={this.props.isOpen} timeout={300} classNames="fadeIndown" unmountOnExit={true}>
{this.props.children}
</CSSTransition>
</div>
)
}
}
export default Dropdown;
const toggleDropdown = () => this.setState({ isDropdownOpen: !this.state.isDropdownOpen });
const closeDropdownThen = fn => (...params) => {
this.setState({ isDropdownOpen: false });
return fn(...params);
};
under the render you should define like that constant like above. And when you use
<Dropdown
isOpen={isDropdownOpen}
toggleDropdown={toggleDropdown}
className={s.dropDownContainer}
label="Export"
>
<DropdownItem onClick={closeDropdownThen(this.abcFunction)}>
CSV
</DropdownItem>
this is my dropDown component maybe it helps you. Best regards

How to fix v-align styling for imgs with different sizes in Vue.js transition-group?

I prepared example of image slider what I need.
I encounter with styling issue when using images with various dimensions. When element leaving the array, its location is set as absolute value, what is necessary for smooth transition, tho, but the image is also moved up.
I would like to have nice vertical align into middle even leave or enter the array, but could not get on any way.
Another issue, what I would like to solve is when left the window and then went back after a while. The animation running all cycles at once to reach current state instead just stop animation and run after. Maybe it is my responsibility, but browsers doesn't offer nice event to catch blur window or am I wrong?
According to this discussion
Thank you for any ideas.

It tooks a while but on the end I think that I have got better result for sliding animation with changing direction feature.
One annoying think is when I swithing the sliding direction so animation is for a 'microsecond' changed to next state and than return to correct one, after it the animation continue as expected. It is happening only in one direction and I don't know how to fix it. Also last box behave differently too only once. No clue at all.
So just 98% solution :-)

Turn cell content to editable input box

When creating a fluid layout, where content can be dragged around and edited inside a table I ran into a problem.
After clicking on any of the <a></a> hyperlinks the cell content should be replaced by an editable input box.
This gets done, but the cell changes its size and wrecks the original layout.
The cell size should not change after click. It should be possible to achieve this by editing the CSS and adding Bootstrap classes.
var viewModel = function() {
var self = this;
self.gridItems = ko.observableArray(
[{
"rowItems": [{
"name": "Item 1"
}, {
"name": "Item 2"
}, {
"name": "Item 3"
}]
}, {
"rowItems": [{
"name": "Item 4"
}, {
"name": "Item 5"
}]
}]
);
self.selectedRowItem = ko.observable();
};
//connect items with observableArrays
ko.bindingHandlers.sortableList = {
init: function(element, valueAccessor, allBindingsAccessor, context) {
$(element).data("sortList", valueAccessor()); //attach meta-data
$(element).sortable({
update: function(event, ui) {
var item = ui.item.data("sortItem");
if (item) {
//identify parents
var originalParent = ui.item.data("parentList");
var newParent = ui.item.parent().data("sortList");
//figure out its new position
var position = ko.utils.arrayIndexOf(ui.item.parent().children(), ui.item[0]);
if (position >= 0) {
originalParent.remove(item);
newParent.splice(position, 0, item);
}
ui.item.remove();
}
},
connectWith: '.sortable-container'
});
}
};
//attach meta-data
ko.bindingHandlers.sortableItem = {
init: function(element, valueAccessor) {
var options = valueAccessor();
$(element).data("sortItem", options.item);
$(element).data("parentList", options.parentList);
}
};
//control visibility, give element focus, and select the contents (in order)
ko.bindingHandlers.visibleAndSelect = {
update: function(element, valueAccessor) {
ko.bindingHandlers.visible.update(element, valueAccessor);
if (valueAccessor()) {
setTimeout(function() {
$(element).focus().select();
}, 0); //new RowItems are not in DOM yet
}
}

On your table, set table-layout to fixed. Another improvement would be to make the inputs take up the entire space of the cell.
Here are the css changes to make:
.sortable-item input {
display: block;
margin: 0 !important;
width: 100%; /* Added this property */
}
/* Added this rule */
.sortable-row > table {
table-layout: fixed;
}

Custom ReactJS component that respects 'valueLink'

I'm building a custom ReactJS component (A 'Select2' dropdown library wrapper) and want to implement support for the standard two-way binding helper with the 'valueLink' parameter.
However it appears the mixin to handle the 'valueLink' parameter only applies to standard components, not custom components.
Is there a way to have my component implement the standard valueLink behaviour automatically, or will I need to explicitly parse and implement this support myself (Potentially introducing bugs or odd behaviours that aren't present in the base library)
The object returned from this.linkState when using the LinkedStateMixin has two relevant properties: value and requestChange(). Simply use those two properties as your value and change handler, respectively, just as if they had been passed to your custom component via value and onChange.
Here's an example of a composite component that wraps a jQuery color picker; it works both with valueLink and with standard value and onChange properties. (To run the example, expand the "Show code snippet" then click "Run code snippet" at the bottom.)
var ColorPicker = React.createClass({
render: function() {
return <div />;
},
getValueLink: function(props) {
// Create an object that works just like the one
// returned from `this.linkState` if we weren't passed
// one; that way, we can always behave as if we're using
// `valueLink`, even if we're using plain `value` and `onChange`.
return props.valueLink || {
value: props.value,
requestChange: props.onChange
};
},
componentDidMount: function() {
var valueLink = this.getValueLink(this.props);
jQuery(this.getDOMNode()).colorPicker({
pickerDefault: valueLink.value,
onColorChange: this.onColorChange
});
},
componentWillReceiveProps: function(nextProps) {
var valueLink = this.getValueLink(nextProps);
var node = jQuery(this.getDOMNode());
node.val(valueLink.value);
node.change();
},
onColorChange: function(id, color) {
this.getValueLink(this.props).requestChange(color);
}
});

Input effect on keyboard tab -> focus, but NOT on click

When a user 'tabs over' to an input, I want the focus effect to be normally displayed, but on click, I don't want it to be visible.
User hits tab, now focussed on toggle button, I would like the toggle button to have slight glowing outline, which I'm currently able to do.
Now,
User clicks on the toggle button or it's associated label, toggle changes as usual,
BUT, I want the glow to never appear in the first place, or to disappear as quickly as possible.
I know about .blur(), and right now I'm having to use a setTimeout for a lazy fix, but I'd like to know if there's a better way to accomplish this, or if there's possibly a CSS only solution
I think a lot of front-end developers struggle to find a balance between aesthetics and the best-practices for accessibility. This seems like a great compromise.
Here's how I do it. The idea is to toggle outlining on when the user uses the tab key and turn it back off when they click.
JS
document.addEventListener('keydown', function(e) {
if (e.keyCode === 9) {
$('body').addClass('show-focus-outlines');
}
});
document.addEventListener('click', function(e) {
$('body').removeClass('show-focus-outlines');
});
Styles
body:not(.show-focus-outlines) button:focus,
body:not(.show-focus-outlines) [tabindex]:focus {
outline: none;
}
I'm currently doing something similar for my company. Unfortunately you must use JavaScript since CSS doesn't support this use case.
Here's what I've done.
var btns = document.querySelectorAll('button');
var onMouseDown = function (evt) {
evt.target.dataset.pressed = 'true';
};
var onMouseUp = function (evt) {
evt.target.dataset.pressed = 'false';
};
var onFocus = function (evt) {
var element = evt.target;
if (element.dataset.pressed !== 'true') {
element.classList.add('focus');
}
};
var onBlur = function (evt) {
evt.target.classList.remove('focus');
};
for(var i = 0, l = btns.length; i < l; i++) {
btns[i].addEventListener('mousedown', onMouseDown);
btns[i].addEventListener('mouseup', onMouseUp);
btns[i].addEventListener('focus', onFocus);
btns[i].addEventListener('blur', onBlur);
}
* { box-sizing: border-box; }
body { background-color: white; }
button {

Basically instead of relying on browser's native focus I add/remove a focus class on my button depending on the situation.
If you use the what-input.js plugin you can apply styles specifically for keyboard users. You can use the following code to highlight a button that has been tabbed to. I've found what-input to be a reliable plugin (comes bundled with Zurb Foundation) and is currently regularly maintained.
// scss
body[data-whatinput="keyboard"] {
button {
&:focus {
// other highlight code here
box-shadow: 0 0 5px rgba(81, 203, 238, 1);
}
}
}
or
/* vanilla css */
body[data-whatinput="keyboard"] button:focus {
box-shadow: 0 0 5px rgba(81, 203, 238, 1);
}
