Question

 function Human(name,currentMail,currentScore,newScore){
 this.name=name || document.querySelectorAll('#e1').value || "Enter Name";
 this.currentMail= currentMail || document.querySelectorAll('#e2').value ||
  "Enter Email";
 this.currentScore=currentScore || document.querySelectorAll('#e3').value || 
 "Enter    Score";
   this.changeScore = function(ns){
                        if (ns!=""){
                        console.log(ns+" Is Your New  Score");
                        this.currentScore=ns;}
                        };

 this.changeMail = function(cmail){
                        if(cmail!=""){
                        console.log(cmail + " Is Your New Mail");
                        this.currentMail = cmail};
                        };
 this.Xport = function(){
                        var exporte=
                        window.open("", "MsgWindow", "width=200, height=100");
                        exporte.document.writeln("<p>"+ this.name +
                        " "+this.currentMail+
                        " " + this.currentScore "</p>");
                        };                          
  };
 var ilan = new Human();
 ilan.name= "ilan Vachtel";
 ilan.currentMail = "ilanvac@gmail.com";
 ilan.currentScore = "95";
 ilan.newScore = "89";
 ilan.changeScore("89");
 console.log(ilan.currentScore);
 ilan.changeMail("ilanvac@013.net");
 console.log(ilan.currentMail);
 var haim = new Human();
 haim.name = "Haimon";
 haim.currentMail="ilanvac@013.net";
 haim.currentScore="54";
 console.log(haim);
 haim.changeScore("77");
 haim.changeMail("haimvac@gmail.com");
 haim.Xport();

这是JavaScript中的一个Obect Oriented文件，尝试将一些窗口中的一些东西导出到另一个窗口之后从输入值中收集它们在表单或手动输入中，我总是得到“Xport函数中的语法错误，它无效，我做错了什么？”

Answer 1

您在+之前错过了this.name：

this.Xport = function(){
                        var exporte=
                        window.open("", "MsgWindow", "width=200, height=100");
                        exporte.document.writeln("<p>" this.name +" "+this.currentMail+
// Here -----------------------------------------------^
                        " " + This.currentScore "</p>");
                        };                          
};

Answer 2

将This.currentScore更改为this.currentScore，不要错过字符串concat中的+。

为什么它不让我使用窗口打开，我做错了什么？
