问题 I am attempting to change the background of a tab of my application by selecting a Radio Button from a RadioGroup, however I am not sure how to go about this. So far I have Favs.java: import android.app.Activity; import android.os.Bundle; public class Favs extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.favs); } } which points to this .xml file -> favs.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout

问题 I'm really struggling trying to create smooth CSS transitions in Safari. I'm trying to hide/show divs by changing their height with a JavaScript onclick event. The resulting transitions are nice and smooth with Chrome, Firefox, and Edge. However with Safari it just looks bad and must be around 15 fps when rendering.

问题 I have noticed when user clicks on a link with, say middle button, or shift/ctrl+left button, click handler attached to hyperlink is not called. I have seen solutions to track mousedown event, but what I'd like is to track exact event of following a link. Are there any suggestions? Thanks 回答1: mousedown / mouseup is indeed the only way you can get notified of middle button interaction, so detecting a down-then-up event without intervening mouseout event is more or less the best you can do. It

问题 I want to have onClick() event on <h1> to <h6> (any of heading tags) for running some javascript. Please give me some example to have onClick() event in <h1> which shows some alert() message. Thanks :) 回答1: It's called the inline event registration model. And yes, you can do more or less what you're asking after. But please don't do this. It's ancient and reliable, yes. But the drawback is that it requires you to put your JS behaviors into your XHTML structure. You are much better off using

问题 I'm using an ItemsControl to display a list of databound items, for each the core of the DataTemplate is a Grid upon which I've placed all the bound controls. I would like to be able to click on the entire area for each item in the list. But I cannot figure out how to make the area clickable.

First example: (Submits form + logs to console but doesn't fire event) <!-- Analytics tracking code --> <form action="test.php" id="form" method="post"> <input type="text" name="name" id="name"> <!--

问题 Is there a way to include some php file at javascript onClick ? like, if(isset(something)) ? include "file.php"; Please help! 回答1: No. That's PHP syntax. PHP executes completely on the server and the result is sent back to the client. Clicks are on the client side. Javascript handles those. Your can't mix the two.
