利用这个类可以保存方法的的实参,函数以后备用。在实例生成时会产生一个序列号用来标识是否来自undo或者redo的调用,从而避免存入缓存栈。 在浏览器中用调试工具看调用结果 View Code 1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 2 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 3 <html xmlns="http://www.w3.org/1999/xhtml"> 4 <head> 5 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> 6 <title>javascript</title> 7 </head> 8 9 <body> 10 <input type="button" value=" - " id="a" /> <input type="button" value=" + " id="b" /> 11 12 <input type="button" value=" - " id="c" /> <input type="button" value=" + " id="d" /> 13 <script type="text

Iphone Custom Scrollview indicator

主宰稳场 提交于 2020-01-02 04:28:11
问题 I am currently working on an application for a client, and they have made an odd request. The request involves putting a custom image as the indicator for the scrollview. I am not even sure if this is possible but if it is can you please let me know how one would go about doing that. Thanks 回答1: UIScrollView streches a small, semi-transparent circle image to generate its scrollbars. You can find this image as the first subview of a UIScrollView : UIImageView *circle = [scrollView.subviews

How to Create a Single Dummy Variable with conditions in multiple columns?

老子叫甜甜 提交于 2019-12-29 01:31:30
问题 I am trying to efficiently create a binary dummy variables (1/0) in my data set based on whether or not one or more of 7 variables (col9-15) in the data set take on a specific value (35), but I don't want to test all columns. While as.numeric is ideal usually, I can only get it to work with one column at a time: data$indicator <- as.numeric(data$col1 == 35) Any idea how I can modify the above code so that if any of data$col9 - data$col15 are "35" then my indicator variable takes on a 1?

问题 i have a collectionView, with 8 Items. One item is TableViewController, and downloading Images for cell BackgroundView. When i just click on Item, the TableView appears 2-3 second later.

When do i know the TableView is finished with downloading? Because when i click the item, the code from "TableViewController" is running,

creating a matrix of indicator variables

故事扮演 提交于 2019-12-24 07:56:27
问题 I would like to create a matrix of indicator variables. My initial thought was to use model.matrix, which was also suggested here: Automatically expanding an R factor into a collection of 1/0 indicator variables for every factor level However, model.matrix does not seem to work if a factor has only one level. Here is an example data set with three levels to the factor 'region': dat = read.table(text = " reg1 reg2 reg3 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 1 0 0 0 1 0 0 1 0 0 1 0 0 0 1 0 0 1 0 0 1 0 0
