从外部JS文件调用HTML内容
[英]Calling HTML content from external JS file
问题描述
I'm having an issue with what seems like a simple enough task. 
我在一个看起来很简单的任务上遇到了问题。 I have a web page where I need to load in and remove div content as the user clicks buttons. 我有一个网页，需要在用户单击按钮时加载并删除div内容。 My code doesn't seem to work though. 我的代码似乎不起作用。
The html: 的HTML：
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Main Page</title>
<link rel="stylesheet" href="assets/css/stylemain.css"/>
<script src="assets/js/introduction.js"></script>
</head>
<body>
<div id="container">
<div id="content">
<div id="slide1">
<p>Here is the first trigger. It should look something like this</p>
<p><input type="button" onclick="part2()" value="Click Me!" /></p>
</div>
</div>
and the .js file: 和.js文件：
function part2() {
document.write("<div id="slide2">
<p>Here is the second trigger. It should be to the left</p>
<p>next line goes here</p>
</div>")
}
It's coming up with a syntax error on line 2 of the js file (the document.write line) but I can't figure out why. 它在js文件的第2行上出现了语法错误（document.write行），但是我不知道为什么。 I tried it both with and without quotations but to no avail. 我尝试使用带引号和不带引号，但均无济于事。 Any help would be appreciated. 任何帮助，将不胜感激。

You have to escape the quotes: 您必须转义引号：
function part2() {
document.write("<div id=\"slide2\">\n<p>Here is the second trigger. It should be to the left</p>\n<p>next line goes here</p>\n</div>");
}

A slightly cleaner solution is to use a combination of single quotes and double quotes: 稍微干净一点的解决方案是结合使用单引号和双引号：
function part2() {
document.write('\
<div id="slide2">\
<p>Here is the second trigger. It should be to the left</p>\
<p>next line goes here</p>\
</div>'
);
}
Note that if you want to use a string broken into multiple lines you must add the '\\' in the end of each line to let JS parser know the string continues to the next line. 请注意，如果要使用分成多行的字符串，则必须在每行的末尾添加“ \\”，以使JS解析器知道该字符串继续到下一行。
