  • cookie设置

    问题: cookie设置好后,谷歌浏览器下-->只有本页面有值,但是在其它浏览器下正常.

    $.cookie("userName",$("#loginName").val(),{expires:7});
    $.cookie("password",$("#loginPW").val(),{expires:7});    

    原因是: 木有设置cookie路径...--> 搞定

    $.cookie("userName",$("#loginName").val(),{expires:7,path:'/'});
    $.cookie("password",$("#loginPW").val(),{expires:7,path:'/'});    

    使用了jquery.cookie.js: 代码如下-->

    /*jslint browser: true */ /*global jQuery: true */
