Function with parameters
Syntax:
function sum(parameter 1, parameter 2){
Function code;
}
Note: According to the needs of partners, there are not fixed 2 parameters, one can be used, or 3 can be used
Let’s write an example of a function with parameters, the code As follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>函数</title>
<script type="text/javascript">
function sum(a,b){
var c= a+b;
document.write(c);
}
sum(3,5);
</script>
</head>
<body>
</body>
</html> In this way, the code of our function will be relatively concise
Let’s write an example below:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>函数</title>
<script type="text/javascript">
function sum(a,b){
var c= a+b;
document.write(c);
}
sum("欢迎来到","php中文网");
</script>
</head>
<body>
</body>
</html>
