    javascript当中排序比较器用法

    例 1.5(排序比较器) <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"/> for teach. <script type="text/javascript"> function sortNumberqixy(a, b) { /* 马克-to-win returned value type: Array object JavaScript syntax: - myArray.sort() - myArray.sort(aComparator) Argument list: aComparator A function object that will compare two items and returns a flag indicating their order in the sort collating sequence. Sort the elements in an array. You must make sure the comparator returns one of the following three values: Negative integer(qixy: not a boolean.) - signifies that the first argument is less than the second.(qixy the whole final result is that small number is in front.) Zero - Signifies that both arguments are the same. Positive integer - Signifies that the first argument is larger than the second. qixy: int=parseInt(String) */ if (parseInt(a) < parseInt(b)) return -5; if (parseInt(a) > parseInt(b)) return 4; else return 0; /* the following is a simple method */ //return a - b } var arr = new Array(3) arr[0] = "9" arr[1] = "6" arr[2] = "6" arr[3] = "26" arr[4] = "10001" arr[5] = "2" document.write(arr + "
    "); /* note that if we don't give the comparator, sort will use the default way to sort. then it will sort according to String,then its order is 10001,2,26,6,6,9 */ document.write("排序之后:" + arr.sort()); document.write("排序之后:" + arr.sort(sortNumberqixy)); </script> </head> <body> </body> </html>

    【整理】待毕业.Net码农就业求职储备

    声明:本文题目来源于互联网,仅供即将从学校毕业的.Net码农(当然,我本人也是菜逼一个)学习之用。当然,学习了这些题目不一定会拿到offer,但是针对就业求职做些针对性的准备也是不错的。此外,除了技术上的准备外,要想得到提升,还得深入内部原理,阅读一些经典书籍(例如Jeffrey Richter的《CLR via C#》)以及借助Reflector或ILSpy反编译查看源码实现,知其然也知其所以然,方能得到感性认识到理性认识的飞跃!另外,本来想将本文标题取为就业求职宝典,但一想这名字太LOW了,而且太过浮华了,本文也根本达不到那个目标,于是将其改为储备,简洁明了。
