Javascript

Java script

Within a myShop custom-layout page a script tag can be used to include custom javascript functions or a reference to a javascript file. However, there are some rules which should be followed when doing so.

Including a javascript file through a <script language="javascript" src="http://www.mijnwinkel.nl/script/somescript.js"></script> may not be done within the <body> element of the page. This should be done within the <head> element instead. – see example one

There are two ways to include comments in the code – with two forward slashes // -, inline and across multiple lines – starting with /* and ending with */. Only the second method can be used within a myShop custom-layout. – see second example
Each statement within a javascript function may be closed with a semicolon – ; -. Within a myShop custom layout closing statements with a semicolon is mandatory, the only exceptions to this are the last line of a javascript block and the last statement with a block between braces {}. – see third example

Below some links (in Dutch) which give more information on javascript:

Example 1

<head>
        <!- Including a javascript file is allowed here ->
        <script language="javascript" src=" http://www.mijnwinkel.nl/script/somescript.js"/></script>
</head>
<body>
        <!- Including a javascript file within the body is not allowed ->
        <script language="javascript" src=" http://www.mijnwinkel.nl/script/not_oke.js"/></script>
</body>

Example 2

<head>
        <script type="text/javascript">
                /* This form of comment is permitted. */
                alert("hello"); // this form of comment is not permitted.
                alert("doesnt work");
        </script>
</head>
<body>
</body>

Example 3

<head>
        <script language="javascript">
                /* Behind each line (statement) should be a semicolon. */
                alert("hello");
                var i=0,n=1;
                for (;i<100;i++) test(i);

                function test(n){
                        /* Hier hoeft geen puntkomma achter, laatste statement voor een } */
                        alert(n)
                }
        </script>
</head>
<body>
