lastIndexOf() 方法可返回一个指定的字符串值最后出现的位置,在一个字符串中的指定位置从后向前搜索。 stringObject.indexOf(searchvalue,fromindex) 该方法将从头到尾地检索字符串 stringObject,看它是否含有子串 searchvalue。开始检索的位置在字符串的 fromindex 处或字符串的开头(没 有指定 fromindex 时)。如果找...

该方法将从头到尾地检索字符串 stringObject,看它是否含有子串 searchvalue。开始检索的位置在字符串的 fromindex 处或字符串的开头(没 有指定 fromindex 时)。如果找到一个 searchvalue,则返回 searchvalue 的第一次出现的位置。stringObject 中的字符位置是从0 开始的。
/C:string 使用指定字符串作为文字搜索字符串。 如:findstr /c:"a b" 1.txt 就会找出含"a b"的行并输出来(注意a和b中间有空格) 如果不用参数/c:findstr "a b" 1.txt 就会输出含有字母 a 或 b 的行。 /G:file 从指定的文件获得搜索字符串。 (/ 代表控制台)。
