无法使用JavaScript打印表格

Unable to print table using JavaScript

本文关键字：打印 表格 JavaScript      更新时间：2023-09-26

我想使用javascript以表的形式打印对象的数据。我写的代码没有显示任何内容。请告诉我我在这里做错了什么。

这是我写的代码-

function Movie(id,movieName)
{
    this.id = id;
    this.movieName = movieName;
}
function MoviesWatched()
{
    this.movies = new Array();
}
MoviesWatched.prototype.addMovie = function(id,name)
{
    this.movies[id]=new Movie(id,name);
}
MoviesWatched.prototype.getTable = function()
{
    var movie;
    var table="<table border=1>";
    for(movie in this.movies)
    {
        table += "<tr><td>";
        table += movies[movie].id;
        table += "</td><td>";
        table += movies[movie].name;
        table += "</td></tr>";
    }
table += "</table>";
return table;
}
var myList=new MoviesWatched();
myList.addMovie(1,"Inception");
myList.addMovie(2,"Red");
document.write(myList.getTable());

在getTable函数中，您需要将movies更改为this.movies，并将name更改为movieName

var movie;
var table="<table border=1>";
for(movie in this.movies)
{
    table += "<tr><td>";
    table += this.movies[movie].id;
    table += "</td><td>";
    table += this.movies[movie].movieName;
    table += "</td></tr>";
}
