下次当你问任何问题时，请检查你键入的单词的拼写，并以简洁的方式解释 根据到目前为止的情况，您要做的是使用Javascript，以便它用数组中的下一个（b1到b10）替换指定单击时的主体id。这将处理背景图像之间的移动：
var body_ids = [
"b1",
"b2",
"b3",
"b4",
"b5",
"b6",
"b7",
"b8",
"b9",
"b10"
];
var current_body_id_index = 0;
var next_click = document.getElementById("click_next");
next_click.addEventListener("click", setNextBodyBackground);
var click_previous = document.getElementById("click_previous");
click_previous.addEventListener("click", setPreviousBodyBackground);
function setNextBodyBackground() {
current_body_id_index++;
if (current_body_id_index > 9) {
current_body_id_index = 0;
}
document.body.id = body_ids[current_body_id_index];
}
function setPreviousBodyBackground() {
current_body_id_index--;
if (current_body_id_index < 0) {
current_body_id_index = 9;
}
document.body.id = body_ids[current_body_id_index];
}
