Stop JS function execution while an AJAX call is not finished

[rskiller]

I have wrote a little function to dynamically include CSS file or JS file.I load JS files with jquery function \[code\]$.getScript()\[/code\].I want to prevent my function returns before my AJAX call is finished.I have tried something like this, but it doesn't work :\[code\]CAPTIVEA.resources._includeResource = function(resource) { var ret = false; if (CAPTIVEA.resources.isIncluded(resource)) { // Resource already included => do nothing console.log('CAPTIVEA.resources : "' + resource + '" is already included.'); ret = true; } else { // Resource not included => try to include it var resType = CAPTIVEA.resources.getType(resource); switch (resType) { // Check resource type to know how to include it case 'js': $.when( $.getScript(resource, function(data, textStatus){ console.info('CAPTIVEA.resources : "' + resource + '" dynamically loaded.'); //success }) ).done(function(){ ret = true; }); break; case 'css': // Load CSS file ... break; default: console.error('CAPTIVEA.resources : "' + resource + '" is not an includable resource.'); break; } } return ret;}\[/code\]
