嗨，我正在尝试在每个页面加载时在特定页面上插入特定图像，但我似乎无法理解它，我的代码看起来像这样

function display() {
coursetitle = (x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
coursecode = (x[i].getElementsByTagName("code")[0].childNodes[0].nodeValue);
enrolledyear = (x[i].getElementsByTagName("year")[0].childNodes[0].nodeValue);
semester = (x[i].getElementsByTagName("semester")[0].childNodes[0].nodeValue);
labday = (x[i].getElementsByTagName("labday")[0].childNodes[0].nodeValue);
lectureday = (x[i].getElementsByTagName("lectureday")[0].childNodes[0].nodeValue);
description = (x[i].getElementsByTagName("description")[0].childNodes[0].nodeValue);
graphic = (x[i].getElementsByTagName("graphic")[0].childNodes[0].nodeValue);
 document.getElementById("show").innerHTML = "Title: " + coursetitle + "<br />Code: " + 
+ coursecode + "<br />Year: " + enrolledyear + "<br />Semester:" + semester +
"<br />Lab Day:" + labday + "<br />Lecture Day:" + lectureday +
"<br />Course Description:<br/>" + description;

我该怎么办？

如果图形值具有图像路径

 document.getElementById("show").innerHTML = "Title: " + coursetitle + "<br />Code: " + 
+ coursecode + "<br />Year: " + enrolledyear + "<br />Semester:" + semester +
"<br />Lab Day:" + labday + "<br />Lecture Day:" + lectureday +
"<br />Course Description:<br/>" + description + "</br> <img src='""+graphic +"'" /> ";
