javascript - 菜单下拉并检查它是否是当前项目并重定向

Question

我想用英语或德语作为 JavaScript/jQuery 中的选项创建一个下拉菜单，检查:

check if on a domain  - say happy.com/pizza 
if german is selected on dropdown 
redirect user to 
happy.de/pizza
and I could have a list

if happy.com/pizza got to happy.de/pizza  
happy.com/coke got to happy.de/coke  
happy.com/juice got to happy.de/juice
etc etc.

我已经编写了代码，但是要怎么做呢？

我已经写了一些代码，但我只需要一点帮助:

在这种情况下，我在 www.something.com/beer 页面上并希望它转到德国啤酒页面!

<select>
    <option value="1">English</option>
    <option value="2">German</option>
</select>

if(value == 2)  && is current domain www.something.com/beer{
    window.top.location.href = 'www.something.de/beer'; 
}else if(value == 2)  && is current domain www.something.com/cheese{
    window.top.location.href = 'www.something.de/cheese'; 
}else{
    do nothing
}

我如何得到它来检查下拉列表的值和当前域？

这是我的 Jsfiddle

我真的卡在 && is current section 我该怎么做？

Answer 1

试试这个

if (value == 2 && location.href.indexOf('www.something.com/beer') >= 0) {
    window.top.location.href = 'www.something.de/beer'; 
} else if (value == 2 && location.href.indexOf('www.something.com/cheese') >= 0) {
    window.top.location.href = 'www.something.de/cheese'; 
} else {

}

location.href - 返回当前 url，indexOf 检查当前 url 中是否有你的字符串
