问题 I have a collection of divs with the same class at various positions on a larger div. Is there a way, using jQuery, to determine if any divs are overlapping a given position on the screen? 回答1: Read the section on document.elementFromPoint(): http://www.quirksmode.org/blog/archives/2010/06/more_ie9_goodne.html You can use this to find the "top-most" element at that location. Hide that element, then ask again. If you get another hit, then the 2 divs overlap at that position. 回答2: You could do

问题 I'm trying to delete an item from ListView by Clicking on a picture (imageView). I must do it this way, I've managed to do it by click on the item itself but for this project I'm not allowed to do that. My Adapter extends BaseAdapter and my TaskListItem extends Relative Layout I'm using a custom layout xml. protected void onFinishInflate() { super.onFinishInflate(); textV = (TextView)findViewById(R.id.textViewTask); textP = ((TextView)findViewById(R.id.textPriority)); textR = ((TextView

Is there any difference between using absolute position around a relative position wrap and an absolute position around a static position wrap?

由 半世苍凉 提交于 2019-12-11 19:24:59
问题 I was just wondering if there is any difference between using it in different ways and what is the point of using it around a relative position wrap -- especially if the main target is the top property? Can someone tell me what is the main purpose(s) of using it around a relative position wrap, like in what cases it is important to do so? Here is something that I was trying and I find no difference between using absolute position under a relative and under a static position -- I mean when it

How can a Bash function detect whether it is being used with positional or named arguments?

由 孤者浪人 提交于 2019-12-11 18:57:38
问题 I'm writing a Bash function that is to be capable of attempting to use either positional or named arguments, whereby positional arguments are accessed in the usual "${1}" , "${2}" way and named arguments are accessed using getopts . I have some example code and example usage shown below in order to illustrate what I'm trying to do. The problem is that the check I'm doing on the variable ${*} is just a grep for the character - , which limits greatly the character content of further arguments.

Incredibly strange floating behavior

问题 You're going to have to take a look at the Fiddle for this one The element I'm having trouble with, hoverHelper , is purposed to show next no matter what part of the body is hovered but only after the animation completes When the animation ends, the floated (to take it out of the element flow) transparent overlay hoverHelper is given an absurdly high width and height to cover the entire page in order to apply a hover event to display the element next . My problem, in essence, is that when the

How could I add a class of “bottom” to “#sidebar” once it reaches the bottom of its parent container?

问题 I'm using the code below which adds a class of fixed to #sidebar once it reaches a certain height from the top of the site depending on what page it's on (i.e. home, single, page). In a similar fashion, I would like to add a class of bottom to #sidebar once #sidebar reaches the bottom of its container ( #content ). If the user scrolls back up, the class of bottom should be removed and the class of fixed should be added back. The goal is to try to get the fixed sidebar to move up with the rest

Getting top and left of a CSS scaled element's normal state with jQuery?

由 拟墨画扇 提交于 2019-12-11 16:17:10
问题 I'm scaling an element on hover with transform: scale(1.2); Now I need to get the top and left position on hover, but it gives me the top and left of the scaled position.. Makes sense, but I'd like the normal state top and left? Is there an easy way to get this? 回答1: Depending on transform-origin and the alignment of your element, you can calculate the additional offset by multiplying the width and height by the multiplier of scaleX and scaleY. Example: var element = $("#myDiv"); var prefixes

Find the position of the k-largest element in max-heap

由 不打扰是莪最后的温柔 提交于 2019-12-11 14:59:20
问题 Doing some algorithms homework here :( I need to come up with an equation to find all the possible positions in the max-heap array, where a given k-th element might be. i.e. the largest element (k=1) is at position n=1. The second largest element (k=2) can be at positions n=2\3. Element k=3 can also be in positions n=2\3. ... The 6th largest element (k=6) can be in positions n=4 up to n=7. etc. Didn't really come up with a solid calculation. Any input would be appreciated. 回答1: The 6th
