event-handling

I have written a small stateful React component. When this component loads, in componentDidMount method I am making use of Kendo UI to show the content of the component in a popup window. Here's my code: export class ErrorDialog extends React.Component { constructor(props, context) { super(props, context); this.errorPopupWindow = null; window.addEventListener('resize', this.resizeComponent); this.handleWindowKeyDown = this.handleWindowKeyDown.bind(this); this.handleButtonCloseWindowOnClick = this.handleButtonCloseWindowOnClick.bind(this); this.handleButtonShowDetailsOnClick = this

I have a ListView with custom list adapter. It has OnItemClickListener and OnItemLongClickListner which used to work fine. After then, I had to put a button in the layout of list item and the item click and long click listener stopped working. Here is my sample code: ListView lv=(ListView)findViewbyId(R.id.listview); lv.setAdapter(listviewadapter); lv.setOnItemLongClickListener(new OnItemLongClickListener() { @Override public boolean onItemLongClick(AdapterView<?> parent, View view,int position, long id) { // My code } }); This used to work fine before adding the button in the layout of list

I've created an jQuery Mobile flipswitch like this <select id="flip" data-role="flipswitch"> <option value="animal">Lion</option> <option value="flower">Rose</option> </select> and I listen to changes on this flipswitch $( document ).on( 'change', '#flip', function( e ) { console.log( 'changed' ); } But I don't want the event to be triggered if I change the value of the flipswitch by $( '#flip' ).val( 'flower' ).flipswitch( 'refresh' ); How do I check if a flipswitch has changed by interacting with it directly or setting a value and refreshing the flipswitch? I've created an example of the

My question is related to how the JS engines implement the pattern of asynchronous events when we do something like bind event handlers on a dom for lets say a click event.? Do they have something like a separate thread that is listening to all the click events ? When an event does occur , do they refer the bind list and bubble up the events ? Similar is with Ajax,the asynchronous network call, where the browser spans a new thread that would start listening to the data from the server and when the response is received, it would call the success handler? jfriend00 Read this post about the

I am trying to design a scenario where on a particular event getting triggered, I wanted a few listeners to perform some task. Trying to also manage S.R.P of code, I want to have the listeners in a different source file. I want to know if this is possible using event Emitter. Does event emitter only work on a single source file? var events = require('events'); var em = new events.EventEmitter(); exports.saveScheme = function (req, res) { var dal = dalFactory.createDAL(constants.SCHEME); return new Promise.resolve(dal.PromiseSave(req.body)) .then(function(data){ var schemeId = data._id; em

I have a three-step process that is entirely reliant upon JavaScript and Ajax to load data and animate the process from one step to the next. To further complicate matters, the transition (forward and backward) between steps is animated :-(. As user's progress through the process anchor's appear showing the current step and previous steps. If they click on a previous step, then it takes them back to the previous step. Right now, the entire process (forward and backward) works correctly, if you begin at step 1, but if you jump straight to step 3 then the anchors for step 1 and step 2 also

I am trying to handle the same onSelect event on a jquery datePicker object twice. From what i understand the event can be handled multiple times, but when i try this only one of the event handlers gets fired. It seems to fire the second handler, but not the first. How can i handle the same onSelect event twice without overriding the first one? This is the problem code snippet. $(document).ready(function(){ $('.test').datepicker(); ... $('.test').datepicker('option', 'onSelect', function(dateText, inst) { alert('one'); }); } ... $(document).ready(function(){ $('.test').datepicker('option',
