表达式写法是:/^1\d{10}$/ 解析:^1 以1开头,\d表示数字,\d{10}表示数字出现10次,加上前面以1开头,正好是11个数字,X$表示以X结尾,这里用$表示后面没有了,11个数字后已经是匹配字符串的结尾。结果展示:正则表达式,又称规则表达式。(英语:Regular Expression,在代码中常简写为regex、...
let i=1,j=++i;//i=2,j=2 let i=1,j=i++; // i=2,j=1 需要注意的是,表达式++x并不综合x=x+1完全一样,如一下案例,因为++运算符会把操作数转为数字 eg: let x="1" x=x+"1" //x为 字符串11 ++x;//x为2 8.2.4 递减(--)运算符 递减(--)运算符的操作数也是一个左值。它把操...
