onchange

Is possible to detect in event onChange for <input type=“date”> , when user using graphical calendar and arrows or using keybord number ? I am only interested in VanillaJS solutions. Something like this? function handler(e){ alert(e.target.value); } <input type="date" id="dt" onchange="handler(event);"/> function elog(ev, object) { console.log(object.id + " - " + ev + ": " + object.value); } <label for="dt1">Date not initially set: </label> <input type="date" id="dt1" oninput="elog('input',this);return false;" onchange="elog('change',this);return false;" onblur="elog('blur',this);return false;

I have two spinner in my system. Now I have to change the selected value of the 2nd spinner depending on the first spinner value. As soon as the user will change the 1st spinner value, the 2nd spinner value will set automatically depending upon the 1st spinner's selected value. How to implement this? From the Hello Spinner tutorial: Now create a nested class that implements AdapterView.OnItemSelectedListener. This will provide a callback method that will notify your application when an item has been selected from the Spinner. Here's what this class should look like: public class

im writing on a library i want to include on different pages who might already use the onchange event - is there any way to attach my event to onchange without removing the original one? EDIT: onchange on the window obj. not only a single element - onchange as in a hash change in the url etc. sorry if i confused them! If I'm correct it sounds like you want to inject new code into an existing event. This may help you if you want a pure JavaScript solution and here is a fiddle demonstrating the feature. http://jsfiddle.net/VZCve/1/ var element = document.getElementById("myElementId"); element

I have a select, for which a onchange event is set. The problem is, in Firefox only (FF v. 12), that the onchange event is triggered even if the user does not click on any option; just hovering the option it is enough to trigger it. i.e.: If the user clicks on the select, hovers one of the options and then he clicks outside the select, the value of the select changes (even if the shown value does not) thus the event is triggered. This does not happen if one of elements of the select is already selected. The behavior is more or less the same as in this Mozilla bug: https://bugzilla.mozilla.org

At first I'm absolutely new on web development. I'm trying to develop a Web application which consists of a single page (I started with an empty project trying to follow the mvc pattern). To populate my View I pass a ViewModel through my HomeController to my "Home"View. Now I want to change a few Label-Texts depending on a DropDown selection. ViewModel: public IEnumerable<Models.Language> AvailableLanguages; public Models.Language SelectedLanguage Public IEnumerable<Models.Text> Content; Language: public int ID; public string LanguageText; Text: public Language Language; public string

This doesn't seem to be working: <select id="mySel" onchange="alert('foo')"> <option value="a">a</option> <option value="b">b</option> </select> <script> dojo.byId('mySel').value = 'b'; // select changes, but nothing is alerted </script> (I'm using dojo, but that doesn't really matter.) The 'onchange' name is a little misleading unless you understand that a change event and a value being changed aren't the same thing. A change event occurs when the user changes the value in the browser. I believe you can fire the event manually by calling dojo.byId('mySel').onchange() after you
