What are the alternatives to html5 session storage?(not local storage)

Although sessionStorage is available for iOS, you can do following for legacy support. You can use window.name. It lives through the session (i.e. until the browser tab gets closed):\n\nvar myData = {\n 'foo': 'bar',\n 'foz': 'baz'\n};\n\nwindow.name = JSON.stringify(myData);\n\n\nAnd you can read it back:\n\nvar myData = JSON.parse(window.name);\n\n\nThis of course requires JSON support from the browser, which leaves very old browsers out of the scope.",

You could use a \"global variable\" (I put that in quotes because I'm not sure what it's actually called in Javascript). But basically you could just make an object in one of your javascript files and write to/read from it.\n\nSomething like\n\nvar data = { first: \"first\", second: \"second\" }\n\n\nand just make as many variables in that object as you need. And a function would access it like\n\nfunction(param) {\n var firstData = data.first;\n}\n\n\nOr I guess using cookies is closer to what you described as your own solution, but that seems like overkill if you just need to pass data between Javascript methods.",
