JavaScript Operation Cookies Detailed

This method of operating cookies I used for a long time, but has not encountered any problems, today in the first page to save the cookie, the second page Gets or the third page to get the function, found the limitations of the method, for example, the first page path is http:// Xxxxx/cyb-car2016/h5officeworker/index, the second page path is Http://xxxxx/cyb-car2016/h5AlertController/index, except that the domain name is the same, There is a different namespace, and cookies are saved on the current page by default, so the cookies are saved on the first page, because the second page will not get the cookies because the paths are saved differently. The workaround is to set the Path,document.cookie = name + "=" + Escape (value) + "expires=" + exp.togmtstring () + ";p ath=/" when saving cookies; , where path=/indicates that it is saved under the domain name path and is available globally
