首先看看判断字符串长度的几种方法(英文占1个字符,中文汉字占2个字符) 方法一: function strlen(str) { var len = 0; for (var i = 0; i < str.length; i++) { var c = str.charCodeAt(i); //单字节加1 if ((c >= 0x0001 && c <= 0x007e) || (0xff60 <= c && c <= 0xff9f)) { len++
<input type="text" maxlength="25" oninput="textlength(this)"> <!--输入的内容--><span class="textNumber">0</span>个字符 <!--字符长度--> <!--调用的jquery方法--> function textlength(res) { var len =

[抄题]: Given two strings s and t which consist of only lowercase letters. String t is generated by random shuffling string s and then add one more letter at a random position. Find the letter that was added in t. Example: Input: s = "abcd" t = &q
