How to use stop() properly in jQuery animation with hover event?

阅读更多关于 How to use stop() properly in jQuery animation with hover event?

问题 I use the method below to make some animation. But when I move my mouse in and out really fast and stop it inside the div , the fadeIn() doesn't work and the div keeps transparent. $(".grids").hover(function() { $('.gridscontrol').stop().fadeIn(200); }, function() { $('.gridscontrol').stop().fadeOut(200); }); 回答1: .stop() without parameters simply stops the animation, still leaving it in queue. In this case you want .stop(true) to clear the animation queue as well. $(".grids").hover(function(

问题 I have an application creating a bunch of divs through a loop. Each div has the class "product" so it looks like <div class="product"> !.....stuff here ....! <div class="show_on_hover">...buttons here... </div> </div> so there are about 12 of these same divs per page. I would like to hover over a specific one and show the specific "show_on_hover" div which is initially set to display:none. $('.product').hover(function() { $(.show_on_hover).show(); }, function () { $(.show_on_hover).hide(); }

问题 Using JQuery I am trying to chain a couple of functions when an element has a hover state. I would normally use the .hover event function, but after reading some tutorials I read that using .on is better as you can use one event handler to monitor all bubbling events within a document. However, I am having problems when I chain two functions together like so: $("element").on( "hover", function() { console.log("one"); }, function() { console.log("two"); }); I expected the result to be one two

问题 I am struggling with a reluctant a:hover css style which I cannot override. I tried to inspect the element in Firebug, but I cannot see why it won't work.

a标签的link、visited、hover、active的顺序 2010-06-25 a标签的link、visited、hover、active是有一定顺序的，以下是我一直在用的一个顺序，能正确显示四个颜色，我也不知道有没有其他的顺序能正确显示，如果你没办法判断哪个是对的，那就先用这个吧。 <style type="text/css"> a:link {color: #000;} /* 未访问的链接 */ a:visited {color: #F00;} /* 已访问的链接 */ a:hover{color: #0F0;} /* 鼠标在链接上 */ a:active {color: #00F;} /* 点击激活链接——在你点击该链接之后，页面正在转向新地址的时候，链接显示此颜色；当你已经到了要链接的页面，然后再返回，原页面上的此链接仍是此颜色 */ /* 这的顺序不能显示active的颜色 a:link{color:#000000;} a:active{color:#ff0000;} a:visited{color:#fff;} a:hover{color:#00ff00;} */ /* 其他的顺序还会出现其他的颜色不能正确显示，这里就不再一一举例了。 */ </style> 取消下划线 a{TEXT-DECORATION:none} 来源： https://www

问题 When running the demo App below, the problem I run into is that hover messages for the bottom part of the plot end up running off the screen. Does anybody know if there is a way to adjust the position so that the entire message always falls within the screen boundaries (l,r,t,b)? require('shiny') require('ggplot2') library(DT) ui <- pageWithSidebar( headerPanel("Hover off the page"), sidebarPanel(width = 2 ), mainPanel( tags$head( tags$style(' #my_tooltip { position: absolute; pointer-events
