This question already has an answer here: Storing Objects in HTML5 localStorage 25 answers No, you can't. localStorage (and sessionStorage ) can store only key-value pairs, where values can only be strings.

This question already has an answer here: Storing Objects in HTML5 localStorage 25 answers localStorage is for key : value pairs, so what you'd probably want to do is JSON.stringify the array and store the string in the mycars key and then you can pull it back out and JSON.parse it. For example, var mycars = new Array(); mycars[0] = "Saab"; mycars[1] = "Volvo"; mycars[2] = "BMW"; local
这个问题在这里已经有了答案： 在HTML5 localStorage中存储对象25个答案 localStorage用于key : value对，所以你可能想要做的是JSON.stringify化数组并将该字符串存储在mycars键中，然后可以将其退出并JSON.parse 。 例如， var mycars = new Array(); mycars[0] = "Saab"; mycars[1] = "Volvo"; mycars[2] = "BMW"; localStorage["mycars"] = JSON.stringify(mycars); var cars = JSON.parse(localStorage["mycars"]);
I want to serialize DOM node or even whole window to JSON. For example: >> serialize(document) -> { "URL": "http://stackoverflow.com/posts/2303713", "body": { "aLink": "", "attributes": [ "getNamedItem": "function getNamedItem() { [native code] }", ... ], ... "ownerDocument": "#" // recursive link here

I am having trouble applying a style that is !important . I've tried: $("#elem").css("width", "100px !important"); This does nothing ; no width style whatsoever is applied. Is there a jQuery-ish way of applying such a style without having to overwrite cssText (which would mean I'd need to parse it first, etc.)? Edit : I should add that I have a stylesheet with an !important style t
我很难应用一种!important的风格。 我试过了： $("#elem").css("width", "100px !important"); 这什么都不做 ; 任何宽度的风格都不适用。 是否有一种应用这种风格而不必覆盖cssText （这意味着我需要先解析它，等等）的jQuery-ish方式？ 编辑 ：我应该补充一点，我有一个带有!important样式的样式表，我尝试用!important样式内联来覆盖，所以使用.width()等不起作用，因为它被我的外部!important样式覆盖。 此外，将覆
Is there any way I can create a text file on the client side and prompt the user to download it, without any interaction with the server? I know I can't write directly to their machine (security and all), but can I create and prompt them to save it? You can use data URIs. Browser support varies; see Wikipedia. Example: <a href="data:application/octet-stream;charset=utf-16le;base64,/
有什么办法可以在客户端创建一个文本文件并提示用户下载它，而不需要与服务器进行任何交互？ 我知道我不能直接写他们的机器（安全和所有），但我可以创建并提示他们保存它吗？ 您可以使用数据URI。 浏览器支持变化 请参阅维基百科。 例： <a href="data:application/octet-stream;charset=utf-16le;base64,//5mAG8AbwAgAGIAYQByAAoA">text file</a> 八位字节流将强制下载提示。 否则，它可能会在浏览器中打
