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,但我似乎无法得到它,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;
我应该怎么办?
