如果在检测语言重定向页面期间语句不起作用

Question

Code skips the if statement.

I've searched for a while now for the answer but couldn't find a solution, and since the similar questions are marked as duplicate I wanted to say these first. So here is the code:

    <script type="text/javascript">
    function loadDocC1() {
    var userLang = navigator.language || navigator.userLanguage; 
    var lang = ("en-US");
    if (lang=userLang){
    window.location.replace("http://karabatak.info");
    }else {window.location.replace("http://kontrabandapart.info");}
    }
    </script>

code chooses one direction to go (either one site or other) regardless of variables.

Answer 1

here is the error

if (lang=userLang){

should be

if (lang == userLang){

Have a look at this

Js operators

Answer 2

The problem is in your if statement:

if (lang = userLang)

You're using the assignment operator ( = ) here - this assigns a value to a variable. You want to use the equality / comparison operator ( == ) - this tests whether one value is equal to another. Change your if statement to this:

if (lang == userLang)

And your code will work.
