Two errors are found in the original code.
First, in IE, strings cannot use array subscript to access the value at the specified position. They can only use charAt (index.
Second, in Chrome and Opera, the split (\ 0 * \) method calculates the number of 1 values, which may increase by 1 in some cases.
For example, if the binary value of 12 is 1100, the array
Js location and size (1) -- correctly understand and use DOM attributes related to size and size, and jsdom
In web development, it is inevitable to encounter the problem of calculating the size and location of elements. The solution to this problem is to use some APIs provided by DOM in combination with compatibility, all the content is described in about three articles.

Code As follows:
Copy code The Code is as follows: function g (n ){
VaR n = n. tostring (2 );
VaR COUNT = 0;
For (VAR I = 0; I {
If (N [I] = "1 ")
Count ++;
}
Return count;
}
I think this writing is very troublesome. I suddenly thought that I could use the JS split method to calculate the number of 1. The split parameter is regular \ 0 * \, which separates 1 in

During the writing of "WCF Technical Analysis", I had a new understanding of WCF. For this reason, I started my third WCF series with the title of the book. The purpose of this series is to supplement the "WCF Technical Analysis" and describe some of the content in the book. It also covers many content that is reluctantly abandoned due to space reasons.
In the first article of this series, I will give a general explanation of the basic architecture of WCF. However, I will find a new way by refer

This is a history that all people in the computer industry, especially software developers, need to understand. The legendary history of UNIX is the most representative of the whole computer world culture. It has the greatest and most profound influence on the whole computer world culture. His experience in the past has brought us a new trend of thought in the computer world.

Last time I used jmail.net to write a Web-based email sending applet, which is suitable for real-time email sending, such as obtaining and retrieving passwords. However, in actual use, there is also a need to send scheduled emails. For example, I want to add an "email reminder" function to the system, users can include the things to be reminded, send an email automatically at the specified time, or list their colleagues on their birthdays today, and send e-mails in the name of the Human Resource

thought:question : Can AYSNC be used for recursive calls, such as a crawler, a function that iterates through all the file information in a folder? Why?SummarizeThis is another cliché of technology sharing, but after writing it, the process management of asynchronous operations becomes clearer. AYSNC is good, but it is not omnipotent, it is useless for the code that repeats itself, because the callback that restricts the task is once. Follow-up, there will be opportunities to continue to study
