[英]Internet Explorer Local Storage
I have a application which works great on all browsers but IE. 我有一个应用程序,适用于除IE之外的所有浏览器。 I am using the local database provided with HTML5. 我正在使用HTML5提供的本地数据库。 I need to store 3 attributes for the users of the application. 我需要为应用程序的用户存储3个属性。 I know in IE I can't use the database approach and I was thinking of using 3 arrays stored in local storage, one array for each attribute. 我知道在IE中我不能使用数据库方法,我想使用存储在本地存储中的3个数组,每个属性一个数组。 Is there a better (and easier) way of doing this? 这样做有更好(更简单)的方法吗?
Thanks 谢谢
For example, I want to store 1) destination 2) where they are from 3) date So I was thinking I will store an array for destinations, an array fro from locations and an array for dates. 例如,我想存储1)目的地2)它们来自3)日期所以我想我将存储目的地数组,来自位置的数组和日期数组。 Then using some id I can index the arrays and get the corresponding information. 然后使用一些id我可以索引数组并获取相应的信息。
If you need local storage, then you need local storage! 如果您需要本地存储,那么您需要本地存储! Based on the information you describe, I think it's probably too heavy to use in a session cookie. 根据您描述的信息,我认为在会话cookie中使用它可能太重了。
Check out the docs . 查看文档 。 Be aware that only IE8+ supports this, so if you need to support other versions - you'll need to do some extra work. 请注意,只有IE8 +支持此功能,因此如果您需要支持其他版本 - 您需要做一些额外的工作。
I would personally enable localStorage where possible, then fall back to a round-trip to the server if the browser doesn't support it (and the data is definitely too much for cookies). 我个人会在可能的情况下启用localStorage,如果浏览器不支持它,则会回到服务器的往返(并且数据对于cookie来说肯定是太多了)。
Keep in mind that the polyfills suggested by Rafael will fall back to cookies if the browser doesn't support localStorage etc. Be sure to test with a good spread of data, and keep in mind that it will be sending all that data with each request (which has it's own ramifications). 请记住,如果浏览器不支持localStorage等, Rafael建议的polyfill将回退到cookie。请务必使用良好的数据传播进行测试,并记住它将在每次请求时发送所有数据(它有它自己的分支)。
For IE, you can use a polyfill to simulate a native localStorage: https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-browser-Polyfills 对于IE,您可以使用polyfill来模拟本地localStorage: https : //github.com/Modernizr/Modernizr/wiki/HTML5-Cross-browser-Polyfills
LocalStorage uses a key:value system. LocalStorage使用密钥:值系统。 But you can save more than one data in one key, using JSON.Stringify & JSON.parse. 但是您可以使用JSON.Stringify和JSON.parse在一个密钥中保存多个数据。
localStorage in IE does not work with this url: file:///P:/Dropbox/abc_web/ingrid8/ingrid.htm#car.. IE中的localStorage无法使用此url:file:/// P:/Dropbox/abc_web/ingrid8/ingrid.htm#car ..
through network if it works: file://pedrojelp/p/Dropbox/abc_web/ingrid8/ingrid.htm#car.. 通过网络如果它工作:file://pedrojelp/p/Dropbox/abc_web/ingrid8/ingrid.htm#car ..
