如何在 JavaScript 的 echo 语句中插入 # 字符？

Question

When I include the # glyph in my statement, to return to an anchor on the page, the PHP code fails.

I've tried everything I can think of to resolve this issue, escaping PHP characters, writing JavaScript functions and the list goes on.

if (isset($_POST['name'])) {
    $_POST = array();
    echo "<script>window.location.href='Contact_Us.php#myForm'</script>";
    } else {
    unset($_POST);
}

There are no error messages. The page appears to refresh and the code to unset the POST variables fails.

If you really want to do things that way simply drop out of PHP instead of trying to echo things.

if (isset($_POST['name'])) {
    $_POST = array();
?>
<script>window.location.href='Contact_Us.php#myForm'</script>
<?php
    } else {
    unset($_POST);
}
