jQuery Cookie插件，检查cookie是否未设置

Question

So Im using the jquery cookie plugin and I need to check if a cookie is unset. I set it up something like this:

if ($.cookie('language')==null) { 


}

This doesn't seem to work. Any ideas why?

Answer 1

简单使用：

if($.cookie("language")){}

Answer 2

To see what the plugin is returning, do a console.log() call:

console.log($.cookie("language"));

This should tell you what is being returned from the plugin if you monitor your Inspector / Firebug console.

I think you can get away with just doing if($.cookie("language")) but you'll have to test that.

Answer 3

Line #90 in the source looks like that SHOULD be the result you want. Check for any errors and test what happens if the cookie is set.
