使用回调。这样的事情应该基于你的示例代码。

Use callbacks. Something like this should work based on your sample code.

function someFunc() {

callAjaxfunc(function() {
    console.log('Pass2');
});

}

function callAjaxfunc(callback) {
    //All ajax calls called here
    onAjaxSuccess: function() {
        callback();
    };
    console.log('Pass1');    
}

这将打印 Pass1 立即（假设ajax请求至少需要几微秒），然后在执行 onAjaxSuccess 时打印 Pass2 。

This will print Pass1 immediately (assuming ajax request takes atleast a few microseconds), then print Pass2 when the onAjaxSuccess is executed.
