click

问题 Posting this question largely in the hopes of confirming my suspicions of the behaviour, and thus documenting it for other programmers. (Since I found no record of this anywhere online) I have a site that I'm building, whose nav bar has the following properties: The horizontal section is a <ul> of <li> s and some of the <li> s hav both: A n <a> element taking you to that topic. A hover CSS selector that triggers display:block on a submenu - a nested <ul> which then drops down vertically. On a

问题 I am trying to create a JTextField with an image and a hint. The function of the textfield is a search field to search some books. Now, I like to go a little bit further. I would like to give the image a function. For example, if I click on the image the text in the textfield should be cleared. To achieve this implementation I created a new class and extended it with JTextField. This is the code: public class JSearchTextField extends JTextField implements FocusListener { /** * */ private

问题 In our application, a lot of markers are drawn in different locations and in certain cases at a certain zoom level, markers overlap each other. So when I click on the marker, I expect the top marker's onMarkerClick to be fired but instead it is fired for the last hidden marker i-e the last marker, with no markers behind it. What do you suggest I do? Also, I have no info windows , therefore I return true from onMarkerClick method. 回答1: I found the solution here: https://github.com/googlemaps

问题 There is a simple application that works in Windows. It has very simple interface: squre window with buttons in fixed coordinates. I need to write a program that makes use of this application: to launch it and to click one of buttons (let's say invoke a click at (150,200)). Is there any way to do it in Java or .NET? 回答1: The Java based solution is to launch the app. in a Process and use the Robot to interact with it. The best solution on this thread was by @HFoE but deleted by a moderator.

问题 I have a tree with on click event listeners. I'd like to re-centre my tree on whichever node the user clicked. How do I get the actual x / y values of a tree node inside the click event? 回答1: To get the x/y you must translate the nodes back through whatever translation you've already applied: http://jsfiddle.net/WLaVU shows a working example of what you want. // click event handler function click_handler(d) { // these dudes must be smooshed back through the same transform var x = xs(d); var y

问题 I have a basic app with a sidebar view. Now I want to be able to change the layout by clicking on one of the items in the navigation drawer. How can I do that?

问题 A bit hard to explain, so I've set up a jsFiddle here. Basically, I have some behaviour triggered when a user clicks a checkbox. In another place I'm trying to programatically click the check box and I need to see the exact same behaviour. It doesn't work, seemingly something to do with the order of the click and determining the checked attribute. How can I get the behaviour I'm looking for without resorting to a hack? 回答1: I tend to use change handler here instead (since jQuery normalizes

问题 I've got the following code on my page, and what i'm trying to do is that when a user clicks outside the #loginBox, i want the entire #loginOverlay to fadeout. But i can't achieve this effect without having the fadeout triggered by clicking on #loginBox... It's placed on the bottom of the page, and i have a link on the page that triggers the fadein. But the fadeout is a bit struggling now tbh. I tried doing this: $("#loginOverlay").click(function() { ...fadeout... }); but it gives me the same
