我有这个HTML代码
<html>
<head>
<script type="text/javascript">
window.onload = function(){
document.getElementById("shipping-method").onchange = function(){
window.scrollTo(0, 0);
};
};
</script>
<script>
function calc() {
var subtotal = parseFloat(document.getElementById("subtotal").innerHTML.substring(1));
var shipping = parseInt(document.getElementById("shipping-method").value);
if(shipping == 1) {
var total = subtotal+6.95;
document.getElementById("shipping").innerHTML = "$"+6.95;
} else {
var total = subtotal+17.95;
document.getElementById("shipping").innerHTML = "$"+17.95;
}
document.getElementById("total").innerHTML = "$"+total;
}
</script>
</head>
<body>
<select onchange="calc()" class="shipping-method" id="shipping-method">
<option value="">-Choose a shipping method-</option>
<option selected="selected" value="1">normal shipping - $6.95</option>
<option value="2">Priority Shipping - $17.95</option>
</select>
<div class="calculations">
<table>
<tbody><tr>
<td>Subtotal:</td>
<td id="subtotal">$97.00</td>
</tr>
<tr>
<td>Shipping:</td>
<td id="shipping">$6.95</td>
</tr>
<tr class="total">
<td>Total:</td>
<td id="total">$103.95</td>
</tr>
</tbody></table>
</div>
</body>
</html>下拉菜单在网页的底部,所以我使用第一个脚本在选择其中一个选项并获得总数后将用户带到页面顶部,但两个脚本不能一起工作,我必须删除其中一个才能让另一个工作,如何让两个脚本一起工作而没有任何冲突,谢谢。

您正在重写onchange函数。如果你想做两件事,那么把它们都放在onchange函数中,不要给它赋值两次。
以下是一些示例代码(为简洁起见)。
<html>
<head><title>Example</title></head>
<body>
<select id="shipping-method"></select>
<table></table>
<script type="text/javascript">
function calc() {
// do calculations here
}
document.getElementById("shipping-method").onchange = function(){
window.scrollTo(0, 0); // scroll to top
calc(); // call function
};
</script>
</body>
</html>请注意,我将javascript放在底部是为了避免访问不存在的元素。

试着贴上这个:
function calc() {
var subtotal = parseFloat(document.getElementById("subtotal").innerHTML.substring(1));
var shipping = parseInt(document.getElementById("shipping-method").value);
if(shipping == 1) {
var total = subtotal+6.95;
document.getElementById("shipping").innerHTML = "$"+6.95;
} else {
var total = subtotal+17.95;
document.getElementById("shipping").innerHTML = "$"+17.95;
}
document.getElementById("total").innerHTML = "$"+total;
}就在顶部的函数之前:
window.onload = function(){
document.getElementById("shipping-method").onchange = function(){
window.scrollTo(0, 0);
