我试图将... / js / index.js文件中的javaScript函数调用到... / index.jsp文件。
任何建议都会有所帮助。
以下是两个文件中的代码:
function testing() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
};
};
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<script type="text/javascript" src="js/index.js">
<!-- I want to call testing(); function here -->
</script>
</body>
</html>

首先引用外部index.js
文件,然后在内联脚本元素中调用该函数:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript">
testing();
</script>
</body>
</html>
顺便说一句,你的test.js函数有错误。您不应该在if / else条件之后放置;
,也不应该在函数声明的末尾。正确的语法是:
function testing() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
}
}
或:
var testing = function() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
}
};

你可以这样做
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript" src="js/index.js"></script>
<title>Insert title here</title>
</head>
<body>
<input type = "button" onclick = "javascript:testing()"/>
</body>
</html>
这是最简单的
