在JavaScript中生成随机字符串/字符

我认为这将为您工作：

function makeid(length) {   var result= '';   var characters       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';   var charactersLength = characters.length;   for ( var i = 0; i < length; i++ ) {      result += characters.charAt(Math.floor(Math.random() * charactersLength));   }   return result;}console.log(makeid(5));
