Set the value of the input to null on each onclick event. This will reset the input‘s value and trigger the onchange event even if the same path is selected. var input = document.getElementsByTagName(‘input’)[0]; input.onclick = function () { this.value = null; }; input.onchange = function () { console.log(this.value); }; <input type=”file” value=”C:\fakepath”> Note: It’s … Read more
Because you are calling that function instead of passing the function to onClick, change that line to this: <button type=”submit” onClick={() => { this.props.removeTaskFunction(todo) }}>Submit</button> => called Arrow Function, which was introduced in ES6, and will be supported on React 0.13.3 or upper.
Add this in your input element <input action=”action” onclick=”window.history.go(-1); return false;” type=”submit” value=”Cancel” />
This should work. getElementsByClassName returns an Array-like object (see below) of the elements matching the criteria. var elements = document.getElementsByClassName(“classname”); var myFunction = function() { var attribute = this.getAttribute(“data-myattribute”); alert(attribute); }; for (var i = 0; i < elements.length; i++) { elements[i].addEventListener(‘click’, myFunction, false); } jQuery does the looping part for you, which you need … Read more

Events can be activated at two occasions: At the beginning (“capture”), and at the end (“bubble”). Events are executed in the order of how they’re defined. Say, you define 4 event listeners: window.addEventListener(“click”, function(){console.log(1)}, false); window.addEventListener(“click”, function(){console.log(2)}, true); window.addEventListener(“click”, function(){console.log(3)}, false); window.addEventListener(“click”, function(){console.log(4)}, true); The log messages will appear in this order: 2 (defined first, … Read more
If you want to be able to add this to any elements without having to copy/paste the same code over and over again, you can make a directive to do this. It is as simple as below: import {Directive, HostListener} from “@angular/core”; @Directive({ selector: “[click-stop-propagation]” }) export class ClickStopPropagation { @HostListener(“click”, [“$event”]) public onClick(event: any): … Read more
Real answer: No, it’s not possible. OK, I have just thought of a way. Overlay your page with a div that covers the whole document. Inside that, create (say) 2,000 x 2,000 <a> elements (so that the :hover pseudo-class will work in IE 6, see), each 1 pixel in size. Create a CSS :hover rule … Read more
pointer-events: none; Is a CSS property that makes events “pass through” the HTML-element to which the property is applied. It makes the event occur on the element “below”.
