在AJAX调用未完成时停止JS函数执行

Question

我写了一个小函数来动态包含CSS文件或JS文件.我用jquery函数加载JS文件$.getScript().

我希望在我的AJAX调用完成之前阻止我的函数返回.

我尝试过这样的东西,但它不起作用:

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;
}

您可以使用$ .ajax并将async设置为false,以便在继续之前等待响应:

$.ajax({
   url: resource,
   success: function(data, textStatus) {
                        console.info('CAPTIVEA.resources : "' + resource + '" dynamically loaded.'); //success
   },
   dataType: 'script',
   async: false
});
