value passing on Winjs listview button click
Hi i am working on a winJS application.i have a winjs list and a button inside the listview.I need to pass a value on button click.
suggest use 'iteminvoked' event on the listview.
test.html:
<div class="listview-host">
<div id="listView" data-win-control="WinJS.UI.ListView" data-win-options="{ selectionMode: 'none', tapBehavior: 'invokeOnly', swipeBehavior: 'none' }"></div>
</div>
test.js:
WinJS.UI.Pages.define('/pages/test/test.html',
{
ready: function onready(element, options)
{
...
listView.addEventListener('iteminvoked', this._oniteminvoked.bind(this));
},
_oniteminvoked: function oniteminvoked(event)
{
}
}

I am trying to write an automation script with protractor that will select an element from a react-select dropdown menu. However, when I select the dropdown menu element and use .click(), the menu doesn't open. It seems that the react-select dropdown isn't responding to the .click() call. Is there another method to call on the react-select dropdown that will click the menu and open it?
Code for the dropdown menu.
<div className={ cx('select-container')} data-mr-ass='grey-info'>
<Select
classNamePrefix='info'
components={{
DropdownIndicator: () => <Icon className={ cx('icon-wrap') } iconName={iconNames.downArrow} />,
Option: (props) => <div data-mr-ass='grey-info-options'> <components.Option {...props}/></div> }}
isSearchable={false}
onChange={selectGrayPercent}
options={grayOptions}
placeholder='Select'
value={grayValue}
openMenuOnClick={true}
/>
</div>
</div>
I tried doing $(attr('grey-info')).click(); but the menu doesn't open so I am unable to select any of the options in the menu. data-mr is my div class name to select elements using Protractor.
you can now use protractor-react-selector to identify web elements by react's component, props, and state.
You can identify your target element by:
const myElement = element(
by.react('Select', { someBooleanProp: true }, { someBooleanState: true })
);
Let me know if this helps!
All:
I wonder if it is possible that binding multiple event handlers to same event?
For example:
var LikeToggleButton = React.createClass({
render: function(){
(function toggle(){
this.setState({liked:!like});
}).bind(this);
return (
<div onClick={toggle}>TOGGLE LIKE</div>
);
}
});
Until this point everything seems normal, but I want to add another feature to that button, which is decide by other option:
For example, I have another switch component(could be anything like checkbox or radio button etc.) called "count toggle", which when enabled, the LikeToggleButton's button will be added another onClick handler which is start counting times of button clicked, I know it could be predesignd into the toggle function, but I just wonder if there is a way to append this part to onClick handler?
Thanks
If you want to have multiple callbacks executed when onClick is triggered, you can have them passed from outside, so you'll have access to them in the props object. Then execute them all (note: code not tested):
var LikeToggleButton = React.createClass({
toggle: function() {
this.setState({liked:!like});
},
handleClick: function(e) {
e.preventDefault();
this.toggle();
for (var i=0, l<this.props.callbacks.length; i<l; i++) {
this.props.callbacks[i].call();
}
},
render: function() {
return (
<div onClick={this.handleClick}>TOGGLE LIKE</div>
);
}
});
BUT, if you want to have components connected between them, you should not do that by calling methods inside handlers. Instead you should use an architectural pattern, where Flux is the obvious choice (but there are lots more).
Take a look to Flux, and here you have more choices.
For an extensible way that does't require the component to know about components that use it - save the onClick event before changing it.
This is highlights extracted from the actual working code:
button.jsx
class Button extends React.Component {
constructor(props) {
super(props);
this.state= { callback: false};
}
click(){
//do stuff here
if(this.state.callback) { this.state.callback.call(); }
}
render () {
this.state.callback = this.props.onClick; // save the onClick of previous handler
return (
<button { ...this.props } type={ this.props.type || "button" } onClick={ this.click.bind(this) } className = this.props.className } >
{ this.props.children }
</button>
);
}
}
export default Button;
Then in another component you can use the button and it can have it's own onClick handler:
class ItemButtons extends React.Component {
itemClick () {
//do something here;
}
render () {
const buttons = [
(
<Button onClick={ this.itemClick.bind(this) } className="item-button">
<span>Item-Button</span>
</Button>
)
];
return (<section>{ buttons }</section>);
}
export default ItemButtons;
To group multiple actions on an event
onMouseDown={(e) => { e.stopPropagation(); alert('hello'); }}
Maybe you can set multiple click event handlers on the same one target as described here: https://gist.github.com/xgqfrms-GitHub/a36b56ac3c0b4a7fe948f2defccf95ea#gistcomment-2136607
Code (copied from linke above):
<div style={{ display: 'flex' }}>
<div style={{
width: '270px',
background: '#f0f0f0',
borderRight: "30px solid red",
minHeight: ' 500px',
maxHeight: '700px',
overflowX: 'hidden',
overflowY: 'scroll',
}}
onClick={this.state.ClickHandler}
onClick={this.stateHandleClick}
className="sidebar-btn"
>
<button onClick={this.props.ClickHandler}>props</button>
<button onClick={(e) => this.props.ClickHandler}>props</button>
<button onClick={this.props.ClickHandler}>props</button>
<button onClick={this.state.ClickHandler}>state</button>
//...
</div>
I'm struggling with plugging in the correct selector into jquery. When I plug in ".accordionButton" the entire div is clickable and the functionality works great. However, I want to make only the "h3.toggle a" clickable, but plugging that selector in doesn't work. Is there something else in the jquery I need to change here? Any advice is greatly appreciated. Thanks!
The HTML:
<div class="accordionButton">
<div class="case-top">
<div class="case-left"></div>
<div class="case-right">
<h3 class="toggle">Our Strategy and Results</h3>
</div>
</div><!--end case-top-->
</div><!--end button-->
<div class="accordionContent">sliding content here</div>
The JQUERY:
$(document).ready(function() {
//ACCORDION BUTTON ACTION (ON CLICK DO THE FOLLOWING)
$('.accordionButton h3.toggle a').click(function() {
//REMOVE THE ON CLASS FROM ALL BUTTONS
$('.accordionButton h3.toggle a').removeClass('on');
//NO MATTER WHAT WE CLOSE ALL OPEN SLIDES
$('.accordionContent').slideUp('normal');
//IF THE NEXT SLIDE WASN'T OPEN THEN OPEN IT
if($(this).next().is(':hidden') == true) {
//ADD THE ON CLASS TO THE BUTTON
$(this).addClass('on');
//OPEN THE SLIDE
$(this).next().slideDown('normal');
}
});
/*** REMOVE IF MOUSEOVER IS NOT REQUIRED ***/
//ADDS THE .OVER CLASS FROM THE STYLESHEET ON MOUSEOVER
$('.accordionButton h3.toggle a').mouseover(function() {
$(this).addClass('over');
//ON MOUSEOUT REMOVE THE OVER CLASS
}).mouseout(function() {
$(this).removeClass('over');
});
$('.accordionContent').hide();
});
You are using
$(this)
but you change the selector, you need to change all $(this) selectors to
$('.accordionButton')
FIDDLE
Ok, here is where I'm at... the buttons are now working correctly, but on click all the instances of .accordionContent open, not just next one. ( FYI, I removed the mouseover from this code snipped)
Jquery
$(document).ready(function() {
//ACCORDION BUTTON ACTION (ON CLICK DO THE FOLLOWING)
$('.accordionButton h3.toggle a').click(function() {
//REMOVE THE ON CLASS FROM ALL BUTTONS
$('.accordionButton h3.toggle a').removeClass('on');
//NO MATTER WHAT WE CLOSE ALL OPEN SLIDES
$('.accordionContent').slideUp('normal');
//IF THE NEXT SLIDE WASN'T OPEN THEN OPEN IT
if($('.accordionButton').next().is(':hidden') == true) {
//ADD THE ON CLASS TO THE BUTTON (correct)
$(this).addClass('on');
//OPEN THE SLIDE
$('.accordionButton').next().slideDown('normal');
}
});
I'm guessing the lines:
$('.accordionButton').next().slideDown('normal');
and
if($('.accordionButton').next().is(':hidden') == true) {
are the lines which need editing. I need these two lines to open and close just the "next" .accordionContent instances not all of the instances together.
I am a beginner in jQuery and JavaScript. I have the following problem: Every time I try to open an div area it is immediately collapsing. The HTML is:
<ul class="information"><li><a class="opener" href="#">opener</a> <div class="slide-block"> ...
The JavaScript:
jQuery(".information .opener").on("click", function(event){
var opener = jQuery(this);
// Show/hide the content by toggling active class
opener.parent().find(".slide-block").slideToggle("fast",function(){
opener.parent().toggleClass("active");
});
// Return false to subdue the click
return false;
});
In think it has to do with an upgrade of jQuery...
Thanks in advance

I don't know if it is an easy question but i couldn't find the solution. I want to create 10 buttons in dojo like the button below.
<div style="right: 1px">
<button data-dojo-type="dijit.form.Button" id="SaveChangesDataGrid1" onclick="SaveChanges()">
Save</button>
</div>
but each button with different ID but the same function onClick. so what i want is when the button is clicked the id of the clicked button will be known in the function.
I am using dojo 1.8 any ideas?.
Change your onclick="SaveChanges()" to onclick="SaveChanges(event)" or get rid of it and use data-dojo-props:
<button
data-dojo-type="dijit.form.Button"
data-dojo-props="onClick:SaveChanges"
id="SaveChangesDataGrid2"
>
SaveChangesDataGrid2
</button>
Start your SaveChanges() this way to get id:
require([
"dijit/registry",
"dijit/form/Button",
], function(
registry
) {
window.SaveChanges = function(event) {
var button = registry.getEnclosingWidget(event.target);
console.log("onclick id:", button.id);
}
});
