Question

I have in simulation.jsp the following code, by which I receive some simulation data from struts2 action:

$(document).ready(function() {
var data='<s:property escape="false" value="simInfos" />';
}

Now I do some simulation with this data. After the simulation has been done, how can I reload/refresh this page with button-click without losing this data, which I have received from struts2 action?

Answer 1

$(document).ready(function() {
    var data='<s:property escape="false" value="simInfos" />';
    localStorage["myData"] = data;

    // later on (maybe after page refresh, whatever)
    var myLoadedData = localStorage["myData"];
}

You can treat HTML5’s localStorage like any other object, although it has specific setter and getter functions and can only store strings. Don’t treat it like a permanent cache though, just a place to store some data for a little while. Another reference.
