visible:hidden和dispaly:none的区别

display:none和visible:hidden都能把网页上某个元素隐藏起来，但两者有区别: display:none ---不为被隐藏的对象保留其物理空间，即该对象在页面上彻底消失，通俗来说就是看不见也摸不到。 visible:hidden--- 使对象在网页上不可见，但该对象在网页上所占的空间没有改变，通俗来说就是看不见但摸得到。 例子： <html> <head> <title>display:none和visible:hidden的区别</title> </head> <body > <span style="display:none;"> 你好!</span><span style=" background-color:Green">你好!</span><br /> <span style="visibility:hidden;"> 你好!</span><span style="background-color:Green">你好!</span> </body> </html> 来源： https://www.cnblogs.com/renxinghua/p/11869520.html

Can I hide an image button on a layout, (dimensions and background) until a call to set visible?

问题 I have a hidden image button in one of my xmls layouts, with a background set to a drawable image. I set the visibility to invisible, as I only want the image to display every once in a while. The problem is, even if the drawable isn't shown, the image button still takes us space - Is there a way to hide the background image, and make it's dimensions 0 until I call on it to be shown in my main class? Thanks! Edit: So in my xml, how would I write that? <ImageButton android:id="@+id/myimage"

问题 I have been making a game in SpriteKit and I have come into a problem when supporting all screen sizes. I attempted to resolve the problem by setting all my scenes scale modes to .AspectFill and setting a fixed size for all screens with a width of 480 and a height of 800 as shown: let scene = GameScene(size:CGSize(width: 480, height: 800)) I went to add a border (an SKShapeNode) that aligns to the edges of the game scene and I found that self.frame.width and self.frame.height aren't don't

Finding if element is visible (JavaScript )

I have a javascript function that tries to determine whether a div is visible and does various processes with that variable. I am successfully able to swap an elements visibility by changing it's display between none and block; but I cannot store this value... I have tried getting the elements display attribute value and finding if the the element ID is visible but neither has worked. When I try .getAttribute it always returns null; I am not sure why because I know that id is defined and it has a display attribute. Here is the code of the two different methods I have tried: var myvar = $("

Check div is hidden using jquery

问题 This is my div <div id="car2" style="display:none;"></div> Then I have a Show button that will show the div when you click: $("show").click(function() { $("$car2").show(); }); So right now I want to check if the div #car2 is still hidden before form submission: if($('#car2').is(':hidden')) { alert('car 2 is hidden'); } Now here is the problem. Although the div #car2 already show, I still got alert message which means that jQuery assumes the div #car2 is still hidden. My jQuery version is 1.7.
