Object.keys（obj） ，返回一个数组，数组里是该obj可被枚举的所有 属性名 。请看示例： 示例一： function Pasta(grain, width, shape) { this.grain = grain; this.width = width; this.shape = shape; this.toString = function () { return (this.grain + ", " + this.width + ", " + this.shape); } } console.log(Object.keys(Pasta)); //console: [] var spaghetti = new Pasta("wheat", 0.2, "circle"); console.log(Object.keys(spaghetti)); //console: ["grain", "width", "shape", "toString"] 示例二： var arr = ["a", "b", "c"]; console.log(Object.keys(arr)); // console: ["0", "1", "2"] var obj = {0: "a", 1: "b", 2: "c"}; console.log(Object.keys(obj)); //

Existence of shapes in Powerpoint

问题 I would like to build a condition on a command button on a Macro enabled powerpoint presentation. If the shape exists then I would like it deleted, otherwise the button should produce a statement about the fact that there is no such shape. Currently I am having trouble with existence...! How do I get Power point to recognise the shape is null? Here is my code: If ActivePresentation.Slides(3).Shapes("Picture") Is Nothing Then MsgBox "no Picture" Else ActivePresentation.Slides(3).Shapes(

Shape position wont redraw when dragged with mouse

问题 I have a filled circle drawn on a canvas and I'm trying to get it to move based on a click and drag method with the mouse. I've managed to checked whether the mouse pointer is within the bounds of the circle, and when I drag the mouse, the variable storing the position of the circle updates as it should, but the circle itself is not redrawing as I'm dragging (the most it will do is flicker). My problem is at the end where I'm overriding mouseDragged() . getCanvas().addMouseListener(new

Android: How can i use the layer-list and shape elements to draw a horizontal rule when set as background?

由 扶醉桌前 提交于 2020-01-19 07:14:49
问题 I want to set the background of a Relative or LinearLayout to a custom drawable. I want the shape to draw two horizontal lines across the bottom, leaving the central part transparent (empty). The following draws the horizontal lines centered vertically, where as i need them to be aligned to the bottom of the shape. (If you add a rectangle as an item you can see the shape expands to the dimenstions of the parent, but the lines are still centrally aligned). <?xml version="1.0" encoding="utf-8"?

Create buffer around spatial point data in R and count how many points are in the buffer

问题 I am trying to analyze spatial density of gas station points using R. I need to create a buffer (circle) around the gas stations and count the number of gas stations within the buffer. I'll then need to play around with buffer distances to see what's a reasonable buffer to see something interesting. These are the files I am working with: https://dl.dropboxusercontent.com/u/45095175/sbc_gas.shp; https://dl.dropboxusercontent.com/u/45095175/sbc_gas.shx; https://dl.dropboxusercontent.com/u

CSS3 Full Width Trapezoid / Polygon with text?

由 匆匆过客 提交于 2020-01-17 06:41:09
问题 I'm trying to redo a client site that's currently not responsive and throughout the site she has long images that are trapezoids with text inside. Of course, on devices, you can barely read it. So I'm trying to turn it into CSS using shapes. Tried a bunch of examples but nothing working at the moment. I think the difference is the examples seem to use hard width numbers instead of 100% for fluid width. I have a pen here: https://codepen.io/anon/pen/KmgoqE and here's the code I'm playing with
