<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<script type="text/javascript">
    function goToAddNewsletterAddPage() 
    {
        window.open("Newsletter.aspx","mywindow");

Answer 1

If you look in the console of the browser, you should see a syntax error. 如果在浏览器的控制台中查看，应该会看到语法错误。 Function declarations (the style you've used in your script) must have a function name, so there's a syntax error... 函数声明（您在脚本中使用的样式）必须具有函数名称，因此存在语法错误...

<script type="text/javascript">
    //    ...v-- here
    function () 
    {
        window.open("Newsletter.aspx","mywindow");
    }
</script>

Perhaps you meant: 也许您的意思是：

<script type="text/javascript">
    function goToAddNewsletterAddPage() 
    {
        window.open("Newsletter.aspx","mywindow");
    }
</script>

(There is a different, but related, thing called a function expression , which doesn't have to have a function name [and due to IE bugs is usually better off without one], eg: （有一个不同但相关的东西，称为函数表达式 ，它不必具有函数名称（由于IE错误，通常最好不使用一个函数名称），例如：

var x = function() { /* ... */ };

The key to knowing which is which is to look to see whether the function structure is being used as a right-hand value , eg, the right-hand side of an assignment [ = ] or initializer [ : ], or being passed into a function as an argument. 知道哪个是关键是看function结构是用作右侧值 ，例如，赋值[ = ]或初始化程序[ : ]的右侧，还是传递给作为参数。 If it is, it's a function expression; 如果是的话，那就是一个函数表达式。 if not, it's a function declaration.) 如果不是，则为函数声明。）
