php echo和javascript警告的变量不同[关闭]

问题描述：

I have a dynamic multilanguage website. My php echos the current language right, but javascript doesn't even if loading after body.

My php:

<?php echo $language ?>

This gives me english, portuguese, german or french accordingly to the one is being used.

when i try with javascript this way:

    <script type="text/javascript">
    function language() {
        var ci = {
            language : "<?php echo $language; ?>"
        };
        if(ci.language = 'portuguese') {
            alert(ci.language);
            return false;
            fb_language = "pt_PT";
        } else if (ci.language = 'english') {
            alert(ci.language);
            return false;
            fb_language = "en_US";
        } else if (ci.language = 'german') {
            alert(ci.language);
            return false;
            fb_language = "de_DE";
        } else if (ci.language = 'french') {
            alert(ci.language);
            return false;
            fb_language = "fr_FR";
        } else {
            fb_language = "en_US";
        }
    };
    </script>

<body onload="language();">

It always gives me portuguese in javascript, can't make it alert the right language, but in php it gives me the right language im using.

答

This:

if(ci.language = 'portuguese') {

Should be:

if(ci.language === 'portuguese') {

And so on in the other if statements.

答

Use as: ci.language == 'portuguese' instead of ci.language = 'portuguese'
