JS problem: script writes "true" to screen

Here is my code:

Code:

---

function menu(dropdown) {
        var myindex  = dropdown.selectedIndex
        var SelValue = dropdown.options[myindex].value
        if (SelValue == "no") {
                alert("Please select an item to view information")

        } else {
                var url = "pizza.php?request=menu&mvalue=" + SelValue
                window.open(url,'mywindow','width=225,height=250 toolbar=no statusbar=no')
                return true;
        }

}

---

and the link which I use to call this code:

Code:

---

<a href='javascript:menu(document.menuForm.pizza_options);'>Link</a>

---

When I do this, everything goes as expected, except that "true" is written to the base window. Why does this happen and how can I fix it? Thanks

Not tested:

Code:

---

<a href="file.htm#" onclick='javascript:menu(document.menuForm.pizza_options);'>Link</a>

<a href="#" onclick='javascript:menu(document.menuForm.pizza_options);'>Link</a>

<a href="" onclick='javascript:menu(document.menuForm.pizza_options);'>Link</a>

One of them should have the desired effect

Why put this in an anchor tag? You can put in in the onclick event in a span tag, give it a class that you define in the CSS to look like an anchor link.

Aside from that, leave out the "return true" line. The function will return on its own, you don't need to explicitly tell it to return and to return a value.
