How to show or hide an element: In order to show or hide an element, manipulate the element’s style property. In most cases, you probably just want to change the element’s display property: element.style.display = ‘none’; // Hide element.style.display = ‘block’; // Show element.style.display = ‘inline’; // Show element.style.display = ‘inline-block’; // Show Alternatively, if … Read more
If the e.target is the same element as this, you’ve not clicked on a descendant. $(‘.foobar’).on(‘click’, function(e) { if (e.target !== this) return; alert( ‘clicked the foobar’ ); }); .foobar { padding: 20px; background: yellow; } span { background: blue; color: white; padding: 8px; } <script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js”></script> <div class=”foobar”> .foobar (alert) <span>child (no alert)</span> </div>
onclick=”doSomething();doSomethingElse();” But really, you’re better off not using onclick at all and attaching the event handler to the DOM node through your Javascript code. This is known as unobtrusive javascript.
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” />
<a onclick=”parent.abc();” href=”#” >Call Me </a> See window.parent Returns a reference to the parent of the current window or subframe. If a window does not have a parent, its parent property is a reference to itself. When a window is loaded in an <iframe>, <object>, or <frame>, its parent is the window with the element … Read more
No, that is not possible via code. Android just implements the OnClickListener for you when you define the android:onClick=”someMethod” attribute. Those two code snippets are equal, just implemented in two different ways. Code Implementation Button btn = (Button) findViewById(R.id.mybutton); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { myFancyMethod(v); } }); // some more code … Read more
The best way (actually the only way*) to simulate an actual click event using only CSS (rather than just hovering on an element or making an element active, where you don’t have mouseUp) is to use the checkbox hack. It works by attaching a label to an <input type=”checkbox”> element via the label’s for=”” attribute. … Read more
Here is a better and less tightly coupled way to implement an OnClickListener for a RecyclerView. Snippet of usage: RecyclerView recyclerView = findViewById(R.id.recycler); recyclerView.addOnItemTouchListener( new RecyclerItemClickListener(context, recyclerView ,new RecyclerItemClickListener.OnItemClickListener() { @Override public void onItemClick(View view, int position) { // do whatever } @Override public void onLongItemClick(View view, int position) { // do whatever } }) … Read more
Both are correct, but none of them are “best” per se, and there may be a reason the developer chose to use both approaches. Event Listeners (addEventListener and IE’s attachEvent) Earlier versions of Internet Explorer implement JavaScript differently from pretty much every other browser. With versions less than 9, you use the attachEvent[doc] method, like … Read more
