我在JavaScript中的版权地址不起作用
我在JavaScript中的版权地址不起作用
提问于 2018-10-02 02:19:37
我正试着让它和我的html一起工作。我正在做外部的js和css到我的html。我已经全部连接到我的html文件中。为什么我的文案地址不起作用？不太确定为什么我会有这个问题...是我的html或javascript语法不正确吗？

您已经注释掉了几乎所有的代码。
您应该取消注释您的JavaScript代码，以产生以下结果：
function copyadddress() {
// copy from myaddress to billingaddress
document.forms["myForms"]["myaddress"].value=
document.forms["myForms"]["billingaddress"].value;
alert("checkbox not checked!");
}
function OrderSubmitted() {
// check if firstname is blank
var x = document.forms["myForms"]["firstname"].value;
if (x == "") {
alert("First name must be filled out");
return false;
}
// check if lastname is blank
var x = document.forms["myForms"]["lastname"].value;
if (x == "") {
alert("Last name must be filled out");
return false;
}
alert("Order Submitted!");
}
我希望这能解决你的问题！PS:在超文本标记语言中，确保通过添加>来结束<!DOCTYPE html>标记。
