var pattern1 = /好/g;
console.log(pattern1.test("你好"));

字符串查找：

var pattern1 = /\w/;
console.log(pattern1.test("njkhjkjk"));

空格查找：

var pattern1 = /\s/;
console.log(pattern1.test("njkhjkjk"));

查找页面中有几个人字：

var re = "人中人人人人",
rex = /中/g,
ary = rex.exec(re),
i = 0;while(ary){
i++;
ary = rex.exec(re);
} console.log(i);

查找“.”后面的文字

var
str = "a.swf",
reg = /\./,
temp = "";if(reg.test(str)){temp = RegExp.rightContext;}console.log(temp);
