    copied!<p>I am making a webapp, that uses mobiscroll as a number counter. The numbers are saved via a submit button below it. The problem I have is whenever the user presses the home button, when the webapp is reloaded, it resets the number list. I figured it would be a good idea to save the value to localstorage,and recall it when the app is reopened. Now that's where I am stuck.</p> <p>Here is the function for the button press that works fine:</p> <pre><code>&lt;script type="text/javascript"&gt; function save_it() { //Save the scroll value for later var scrollsave = $('#i').scroller('getValue'); localStorage.setItem("scrollsave", scrollsave); localStorage.saveServer } &lt;/script&gt; </code></pre> <p>I have a function further up, that is giving me trouble, and refusing to work proper, I have tried the following methods:</p> <p>My first attempt to assign</p> <pre><code>&lt;script type="text/javascript"&gt; $(function () { var scrollstate = localStorage["scrollsave"]; if (scrollstate != null) { $('#i').scroller('setValue', scrollstate); } }); &lt;/script&gt; </code></pre> <p>I get an error of, Object x,x,x,x has no method 'join'. </p> <p>Second attempts to convert to array and back, but no luck.</p> <pre><code>var oldscroll = localStorage.getItem["scrollsave"]; var finalsaved = SON.parse(oldscroll); if (finalsaved != null) { $('#i').scroller('setValue', finalsaved); </code></pre> <p>The documentaion on mobiscroll is here <a href="http://docs.mobiscroll.com/22/mobiscroll-core" rel="nofollow">http://docs.mobiscroll.com/22/mobiscroll-core</a> . And it says, "scroller values from the data parameter passed as array". </p> <p>My key, scrollsave is stored with a value of 1,2,1,1 . Which seems to meet the correct formatting to throw into the mobiscroll part.</p> <p>I have a feeling there is something trivial I am overlooking, but I can't figure out what.</p>
