问题 I need to recognize a long click in a JavaScript bookmarklet. So, I cannot use jQuery, neither onclick() event and similar. Is it possible, and how? 回答1: onmousedown , call setTimeout() for the duration of your long click. If the timeout is allowed to expire, it will call its function to do whatever you hoped to do on the long click. However, onmouseup you cancel the setTimeout() if it has not yet expired. <script type='text/javascript'> // t will hold the setTimeout id // Click for 1 second

问题 I have several comboboxes in a UI each with a long list of similar entries (numbers). When the user selects an item from one of the comboboxes, I know the user will choose an entry with a similar value (but likely not the same) from the other comboboxes. Thus, after the user has selected a value, to help avoid forcing the user to do a lot of scrolling, I would like to "pre-scroll" the next combobox dropdown to the vicinity of the last selected value (when this dropdown does not already have a

问题 I've been doing web development for years now and I'm slowly getting myself involved with game development and for my current project I've got this isometric map, where I need to use an algorithm to detect which field is being clicked on.

All the fields have a center point (array of x,y) which the four corners are based on

问题 I have asked a similar question but didn’t get a real satisfying answer, so I will try again here.

问题 I need to be able to handle the double click and single click event on the WPF StackPanel. But there is no such thing as the StackPanel's DoubleClick Event. I want to do 2 different operations in these 2 EventHandlers. Any idea how to do that? Thank you 回答1: The best way is to right your own mouse button handler with a timeout - if the event is fired again within the timeout period, then fire your doubleclick message, otherwise call the single click handler. Here's some sample code ( Edit:
