area

问题 I'm looking everywhere to answer this question but nowhere can I find anything about it. Can anyone tell me whether we can affect the area which received the item hover border-radius property. So that the effect of changes such as color took place after hitting a real area viewed item? Do not block that physically exists in the DOM as a square? This is simple img. and some simple fiddle: www.jsfiddle.net/nawAE 回答1: Well, you can use SVG and pointer-events: https://developer.mozilla.org/en-US

问题 I'm sure this is a simple question, but I can't seem to figure it out. I've got this plot and I want to add vertical lines and shade the area in between to highlight areas of the data. I feel like I should be able to do this using the area function, but can't seem to figure it out. The dates and values are all doubles and are two separate vectors, if that makes a difference. Any help would be greatly appreciated. 回答1: Very basic example about shading an area in a plot. Shading an area

问题 I have this var textarea=$('#content'); textarea.html(textarea.html().replace("PID","111111")); This works partially, but it only finds the first "PID" within the textarea and replaces it to "1111111". There are about 7 others I need to change as well. What I need is a way to find ALL "PID" and replace it with "111111". Thanks in advance. 回答1: Use regex to replace all the occurrences in a string. Try this textarea.html(textarea.html().replace(/PID/g,"111111")); 回答2: textarea.html(textarea

问题 I got an arbitrary shaped curve, enclosing some area. I would like to approximate the number of pixels that the curve is enclosing on an iPhone/iPad screen. How can I do so? A curve is defined as a successive x/y coordinates of points. A curve is closed. A curve is drawn by a user's touches (touchesMoved method), and I have no knowledge of what it looks like I was thinking of somehow filling the closed curve with color, then calculating the number of pixels of this color in a screenshot of a

问题 Given this data set: y<-c(-13,16,35,40,28,36,43,33,40,33,22,-5,-27,-31,-29,-25,-26,-31,-26,-24,-25,-29,-23,4) t<-1:24 My goal is to calculate two areas. The first area would integrate only data from the first part of the curve found above the Zero line. The second area would integrate data from the second part of the curve found below the zero line. First I would like to fit a sine wave to this data. Using this excellent answer: https://stats.stackexchange.com/questions/60994/fit-a-sinusoidal

问题 is it possible to make only a part of a div clickable -- like a clickmap/imagemap? May with jQuery? Hint: i don't want edit the html (misused template with 200 separate html files). 回答1: When your div is clicked, the event handler receives the event, so you can test the position of the click. If needed, you might want to use the clicked element position and size, using $(this).offset() , $(this).width() and $(this).height() . For example : $('mydivselector').click(function(e) { if (e.pageY >

问题 I am trying to set a map area on my image, but I want it to be an octagon so I really need to see what I'm drawing. Unfortunately there is not way for me to style the area tag so that I can see where the mapping is taking place. This is making it really difficult for me to draw these areas, I have to follow it with the mouse every time to know where it begins and where it ends. Is there a better way ? I'm posting this example with a rectangle just to keep things simple, I just want to see it,

问题 I am trying to figure out a way to get the area inside a specific contour line? I use matplotlib.pyplot to create my contours. Does anyone have experience for this? Thanks a lot. 回答1: From the collections attribute of the contour collection, which is returned by the contour function, you can get the paths describing each contour. The paths' vertices attributes then contain the ordered vertices of the contour. Using the vertices you can approximate the contour integral 0.5*(x*dy-y*dx), which

问题 I would like to have a function where I can input a radius value and have said function spit out the area for that size circle. The catch is I want it to do so for integer based coordinates only. I was told elsewhere to look at Gauss's circle problem , which looks to be exactly what I'm interested in, but I don't really understand the math behind it (assuming it is actually accurate in calculating what I'm wanting). As a side note, I currently use a modified circle drawing algorithm which

问题 I've got the following problem. I want to zoom-in a Scatterplot and then select all the displayed elements. It would be sufficient to somehow get the displayed area in the zoomed-in Scatterplot. From the range of this area i could determine which elements are displayed in the area and which are not. \edit: Found the Solution (Implementing AxisChangeListener Interface) import java.awt.Color; import java.awt.Dimension; import org.jfree.chart.ChartPanel; import org.jfree.chart.event
