为什么我不能使用 onclick 事件执行这个简单的 JavaScript 函数？

Question

I am not so into JavaScript and I have the following problem.

Into a JSP page I have the following "link":

<tr onmouseout="Javascript: this.style.background='#FFFFFF'; 
                            this.style.color='#003399';" 
                            onmouseover="Javascript: this.style.background='#003399'; 
                            this.style.color='#FFFFFF'; this.style.cursor='hand';" 
                            onclick="changeLocationTo('edi.do?serv=4.U');">

    <td style="border-top: 0px;">
        Tabella Anagrafica
    </td>
</tr>

So, when the user click on the tr element it is performed the changeLocationTo() JavaScript function passing to it the String 'edi.do?serv=4.U' .

Into this page I have defined the script section:

<script language="JavaScript" src="js/Script.js">
    function changeLocationTo(newLocation) {

        alert("INTO changeLocationTo, nweLocation: " + newLocation);
        loadingPopUp();

        // you may add an timeout here or to handle a popup action like closing it

        document.location.href = newLocation;
    }
</script>

My problem is that when I click on the previous tr link it don't perform the changeLocationTo() function and into the FireBug console is is shown this error message every time that I click on the tr :

ReferenceError: changeLocationTo is not defined

Why? what could be the problem? How can I try to fix it? What am I missing?

您的script元素有一个src属性，因此其中的代码将被忽略，而是加载来自 URL 的脚本。
