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>
下拉菜单位于网页的底部,因此我选择其中一个选项并获取总数后,使用第一个脚本将用户置于页面顶部,但两个脚本不能同时工作,我必须删除其中一个让另一个工作,如何让两个脚本一起工作而没有任何冲突,谢谢。

尝试坚持下去:
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;
}
就在顶部的功能之前:
window.onload = function(){
document.getElementById("shipping-method").onchange = function(){
window.scrollTo(0, 0);
};

您正在覆盖onchange功能。如果你想做两件事,那么把它们放在onchange函数中,不要分配两次。
以下是一些示例代码(简称简称)。
<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放在底部以避免访问不存在的元素。
