我有这段代码:
var curState = 'Agenda';
function switchState(newState) {
curState = newState;
}
function Inbox() {
switchState('Inbox');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the Inbox.";
}
function Friends() {
switchState('Friends');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the Friends.";
}
function Agenda() {
switchState('Agenda');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the Agenda.";
}
function List() {
switchState('List');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the Book List.";
}
function News() {
switchState('News');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the News.";
}
function Notes() {
switchState('Notes');
document.getElementById("u-content").innerHTML = "Currently, you're viewing the Notes.";
}
当然显示的文字是一个测试,我会更改它。关键是,我必须在菜单的这些“状态”中加入大量文本,并在此处简单地输入它并不是很方便,特别是如果稍后要进行更改。因此,我想知道如何在JavaScript中添加不同形式的文件,或者让它们使用JavaScript显示,如* .php文件。
有谁知道怎么做这样的事情?我在互联网上搜索了很多,但找不到对我有用的东西,除了document.getElementById().innerHTML = "";
答案 0 :(得分:1)
有三种简单的方法可以做到这一点:
变体A:通过AJAX调用从服务器获取innerHTML - 类似于
function News() {
switchState('News');
document.getElementById("u-content").innerHTML = "Please wait for News to load.";
//start AJAX call here
}
function AJAXcallOnSuccess() {
document.getElementById("u-content").innerHTML = //Result text from AJAX call;
}
变式B:您的文字已在原始页面中传送,但未显示。像
这样的东西<blah>
...
<div style="display: none;" id="newsPlaceHolder">
This is the text for the news item
</div>
...
</blah>
function News() {
switchState('News');
document.getElementById("u-content").innerHTML = document.getElementById("newsPlaceHolder").innerHTML
}
变体B导致最简单的变体C:在页面中准备好所有DIV,但一次只显示一个。
var activeDiv = null;
function News() {
switchState('News');
if (activeDiv) activeDiv.style.display='none';
activeDiv=document.getElementById("u-content-news");
activeDiv.style.display='block';
}
