Answer 3

たったひとつの質問

スクリプトタグにjavascriptを入れましたか？これをしたらうまくいったので

<a href="register.php" title="" onclick="javaScript:showRegisterRules();">Register</a>

JS

<script>
    function showRegisterRules()
    {
     alert("Registration Rules");
    }

</script>

Answer 4

これを試して：

<a href="#" title="" onclick="javaScript:showRegisterRules();window.location.href='register.php'">Register</a>

Answer 5

You can actually write a generic method here rather than one spessific to any given URL.

<a href="register.php" title="" onclick="showRegisterRules(this);">Register</a>

function showRegisterRules(a)
{
    alert("Registration Rules");
    document.location.href=a.href;
}

This way, you can reuse the same method anywhere within the site to show the alert. This allowing it to go in a script file rather than the html page

Answer 6

これもできます

<a href="register.php" title="" onclick="return showRegisterRules('register.php');">Register</a>

function showRegisterRules(url)
{
 alert("Registration Rules");

 return true;
}
