[js:core] lost binded user functions with node.elfinder('reload')

[nao-pon]

Since node.elfinder ('reload') destroys the elFinder instance once, the registered user function is lost.

As a countermeasure, elFinder provides a new registration method for user functions.

Make the callback function registered for preparation for bootup, and register the callback function with the second argument of new elFinder() or with the option value bootCallback.

• The this object in the function is an elFinder node
• The first parameter is elFinder Instance
• The second parameter is an object of other parameters
  For now it can use dfrdsBeforeBootup Array

The dfrdsBeforeBootup array has a value ofjQuery.Deferred()object. The bootup sequence is suspended until all jQuery.Deferred() is in the resolved state.

$('#elfinder').elfinder(
    // 1st Arg - options
    {
        // Connector URL
        url : 'php/connector.minimal.php'
    },
    
    // 2nd Arg - before boot up function
    function(fm, extraObj) {
        /* any bind functions etc. */
        fm.bind('init', function() {
            // any your code
        });
        // for example set document.title dynamically.
        var title = document.title;
        fm.bind('open', function() {
            var path = '',
                cwd  = fm.cwd();
            if (cwd) {
                path = fm.path(cwd.hash) || null;
            }
            document.title = path? path + ':' + title : title;
        }).bind('destroy', function() {
            document.title = title;
        });
    }
);

OR

$('#elfinder').elfinder({
    url : 'php/connector.minimal.php' // connector URL (REQUIRED)
    // bootCalback calls at before elFinder boot up 
    ,bootCallback : function(fm, extraObj) {
        /* any bind functions etc. */
        fm.bind('init', function() {
            // any your code
        });
        // for example set document.title dynamically.
        var title = document.title;
        fm.bind('open', function() {
            var path = '',
                cwd  = fm.cwd();
            if (cwd) {
                path = fm.path(cwd.hash) || null;
            }
            document.title = path? path + ':' + title : title;
        }).bind('destroy', function() {
            document.title = title;
        });
    }
});
