onclick

问题 I created a search field (id:searchField) and a search button (id:searchButton) using Xpages Custom Controls. I added an onkeypress event on the search field such that it will trigger a click to the searchButton. The searchButton will then reload the page but with url parameters coming from the search field. The problem is that the page reloads but the search parameters are not added to the URL when I press ENTER in the search field , but works properly when I press searchButton. Here are the

问题 I am new to DART. I read the language overview and checked example code in DART editor. So far i could not find how to handle events in DART. For e.g. onclick="call_dart_method()". How can we handle events in DART? 回答1: That's not how you do it on Dart Check here, under the section Events: http://www.dartlang.org/articles/improving-the-dom/ elem.onClick.listen( (event) => print('click!')); 回答2: Also, you might find that being able to optionally declare our variable types makes working with

问题 I am trying to get the absolute position (top and left) of a mouse click relative to the browser/body, not any parent elements within the body. I have a listener bound to the body, but e.pageX and e.pageY are giving me the position relative to a div. Note that I can leverage jQuery and YUI functions. Code that currently does not work correctly: //getting the position function _handleClick(e) { var data = { absX: e.pageX, absY: e.pageY}; _logClickData(data); } //binding the function var

问题 I wrote a page that used buttons with onclick to call a function as part of a set of practice problems and answers for my students. It has worked since July with no issues through Friday, September 5 at least. Today the buttons fail to function at all in Chrome, and I can't figure out why for the life of me. They do continue to function properly in IE. I've posted the simplest code I could write that won't work below. It's awfully simple, and honestly I think it's fine. It seems to work if I

问题 I am a JavaScript beginner and am looking for a way to get the x and y coordinates on a button when it's clicked. This works in Opera, IE9 and Chrome but I can't get it to work in Firefox. Here is my code so far: Function in JavaScript: function buttonClick(subEvent) { var mainEvent = subEvent ? subEvent : window.event; alert("This button click occurred at: X(" + mainEvent.screenX + ") and Y(" + mainEvent.screenY + ")"); } Here is the HTML section: <input type="button" onclick="buttonClick()"

问题 I have table row with click event button with click event, that button is on table row and I have problem. When I hit button, row click event execute too, but I don't want this behavior. I want only button click execute, without row click. 回答1: look at your code this is what you should do in the button click event stopPropagation 回答2: Using jQuery (due to question tag): $('#yourButton').click(function(e) { // stop event from bubbling up to row element e.stopPropagation(); // now do your stuff

问题 With the current version of jQuery (1.8.3) you can still use the following code (showing both a click with and without a namespace): $("span") .on("click", function(e) { console.log('click without a namespace'); }) .on("click.namespace", function(e) { console.log('click with a namespace'); }) .trigger("click!"); // "click without a namespace" JSFiddle However, that seems to be removed in 1.9. Is there a way in the new version of jQuery (the test version) to replicate this feature? Or do I

问题 I have created this activity that should allow me to open a new activity once a button has been pressed. However the OnClickListener does not seem to be working. Am I declaring the buttons wrong? Can someone me out? public class Menu extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.menu); View loginbutton = findViewById(R.id.butlogin); loginbutton.setOnClickListener(this); View recordbutton =

问题 How do I make an ImageButton image change its image when you press it? 回答1: I hope you find this helpful. This can all be done in the XML. 1) Import your images for both pressed and unpressed states into the res/drawable- whichever folder 2) Make your selectors.

You will need to create a different selector for each button
