我不知道如果我的瓦线是很清楚......我的问题是: 我有一个需要等待服务器上的事件JS应用。目前,它民调连续通过XMLHtt prequest服务器数据的每一秒。
I do not know if my tile line is clear enough... My problem is: I have a JS application that needs to wait for an event on the server. At the moment it polls continuous the server data via XMLHttpRequest every second.
我所想的是:是否可以进行呼叫等待,直到例如在PHP中改变一个变量
What I am thinking about is: Is it possible to make the call wait until for example a variable in PHP changes?
我希望我的问题是很清楚。
I hope that my question is clear enough.
谢谢!
