在等待一些异步ajax调用完成时，您无法停止javascript的执行. Javascript根本无法正常工作.

You cannot stop the execution of javascript while waiting for some asynchronous ajax call to finish. Javascript simply doesn't work that way.

相反，您必须重新编写程序，以便要等待异步ajax调用完成的代码将通过回调函数执行，而不是在ajax调用执行后同步执行.

Instead, you have to rework the way you program so that code that wants to wait for an asychronous ajax call to be completed will execute via a callback function, not synchronously after the ajax call executes.
