仅在其他功能的执行完全完成后，如何调用功能

Question

In the following code, I would like to reload the siteadmin pages with the function siteAdmin.reloadPages() only after the storing of the pages porperties CQ.form.SlingSubmitAction(dialog.form, config); is executed sucessfully.

the following function submits a form and then calls a callback() function, which in turn reloads the siteadmin pages:

function foo(dialog, config, callback) {
    var action = new CQ.form.SlingSubmitAction(dialog.form, config);
    dialog.form.doAction(action);
    dialog[dialog.closeAction]();

    callback();
}

function call:

foo(dialog,action, function() {
    var siteAdmin = CQ.Ext.getCmp(window.CQ_SiteAdmin_id);
    siteAdmin.reloadPages();
});

The problem is that the siteadmin pages are not reladed after the pageProperties ( dialog.form ) has been successfully submitted. For example the pageTitle loaded is the old value.

How to reload siteadmin pages only after the form has been successfully submitted?

Answer 1

You can try to specify the success function in the config, something like the one shown below.

function foo(dialog, config, callback) {
    var action = new CQ.form.SlingSubmitAction(dialog.form, {
        success: function(){
            var siteAdmin = CQ.Ext.getCmp(window.CQ_SiteAdmin_id);
            siteAdmin.reloadPages();
        }
    });
    dialog.form.doAction(action);
    dialog[dialog.closeAction]();
}

This would ensure that the siteadmin is reloaded only after you request succeeds.

Check the further options available for your config here .

You should call the callback of foo from success callback of CQ.form.SlingSubmitAction

function foo(dialog, config, callback) {
    var action = new CQ.form.SlingSubmitAction(dialog.form, 
       {
         params: config.params,
         success: function(frm, resp) {
           callback();
         }
       });
    dialog.form.doAction(action);
    dialog[dialog.closeAction]();
}

I don't see any sort of test for whether or not the form-submission was successful. You could simply avoid calling the callback() function until after such a test has been passed. Or, you could put the test inside the callback() function, and not do the page-reload until after the test has been passed. OR, you can estimate how long it takes for the form-submission to be transmitted to the Web Server, and how long it takes the Server to process the data, and then do something like this:

 setTimeOut("callback();", 500); //wait 500 milliseconds (sample estimate)

OR

 setTimeOut("siteAdmin.reloadPages();", 500); //inside the callback() function

Note this assumes the submitted data is always successfully processed, but using setTimeout() is most certainly a generic way to ensure one function is DONE, before another gets called.
