How Do I Handle The Back And Forward Buttons In AJAX


  • 28 Jan, 2012

    While you could go out and create a custom solution that tracks the current state on your application I recommend you leave this to the experts. Dojo addresses the navigation in a browser neutral way as can be seen in the JavaScript example below.
    function updateOnServer(oldId, oldValue, itemId, itemValue) {
    var bindArgs = { url: "faces/ajax-dlabel-update", method: "post", content: {"component-id": itemId, "component-value": itemValue}, mimetype: "text/xml", load: function(type, data) { processUpdateResponse(data); }, backButton: function() { alert("old itemid was " + oldId); }, forwardButton: function(){ alert("forward we must go!"); } }; dojo.io.bind(bindArgs);}
    The example above will update a value on the server using dojo.io.bind() with a function as a property that is responsible for dealing with the browser back button event. As a developer you are capable of restoring the value to the oldValue or taking any other action that you see fit.
