mouseover

问题 I would like to show a close button to be display on a row in a last column (while mouse over on that row) I don't want the close button to be always visible but just on a mouse over. If anyone has an example that would be greatly appreciated. 回答1: this is very simple example css table a{ display: none; } table tr:hover a{ display: inline; } and html <table> <tr> <td>12</td> <td>asdasd</td> <td><a href="">Close</a></td> </tr> <tr> <td>12</td> <td>asdasd</td> <td><a href="">Close</a></td> </tr

问题 Here, I have two side-by-side panel the first_pnl and second_pnl , the second panel is not visible by default. Initial thoughts of what I need: If my cursor is over the the first one ( MouseEnter ) It's BackColor would change to Black Second panel would be visible If my cursor leaves first one ( MouseLeave ) It's BackColor would change back to Gray Second panel would not be visible Which is simple as: Private Sub PanelMouseEnter(sender As Object, e As EventArgs) _ Handles first_pnl.MouseEnter

问题 I have a figure with two or more lines. These lines have additional, important information associated with them, like how many data points were averaged to create the line etc. I would like to access this information in my figure. I thought a good solution for this would be to if you could hover over a line with your mouse and get that extended information. However searching for tooltips/overlays/hover-over on figures seemed to not be fruitful. Example: figure; hold on; plot(1:10,rand(10,1))

问题 I've got a movieclip that I'm using as a button. Within this movieclip is a large shadow that shows when the button is moused over. My problem is that this shadow is effecting the mouseovers and causing a much larger "catch" area for the mouseOver and mouseOut events than I want. I've tried disabling mouse events on that child and as many combinations of mouseEnabled and mouseChildren I can think of. Is it possible to prevent certain elements effecting the mouseover properties of it's parent,

问题 If you have an element that has an animation to move it around, the mouseover and mouseenter events aren't fired unless the mouse is moved by the user. To demonstrate try the block of code below with jQuery. If you put your mouse in front of the moving div so you're not moving the mouse when the div passes by then the mouseover isn't fired and the block doesn't stop. In Firefox the mouseover event is fired without moving the mouse manually over the div, but only if you've moved the mouse at

问题 I'm trying to animate an image of a box by changing it's position on mouseover. I can get it to move once but I need to set it up so that it moves everytime someone mouses over the image. I want to make the users 'chase' the box around the screen. Preferably the animation would loop so that a user can never catch the image ? Here is an example of what I have so far, and below is my jQuery code: $(document).ready(function() { $('#img').mouseover(function() { $(this).animate({ left: '500px' });
