问题：
I've got a search field. 我有一个搜索字段。 Right now it searches for every keyup. 如今，它会搜索每一个键。 So if someone types “Windows”, it will make a search with AJAX for every keyup: “W”, “Wi”, “Win”, “Wind”, “Windo”, “Window”, “Windows”. 所以，若是有人键入“ Windows”，它将使用AJAX搜索每一个键入的内容：“ W”，“ Wi”，“ Win”，“ Wind”，“ Windo”，“ Window”，“ Windows”。 函数
I want to have a delay, so it only searches when the user stops typing for 200 ms. 我但愿有一个延迟，所以它仅在用户中止键入200毫秒时才搜索。 this
There is no option for this in the keyup function, and I have tried setTimeout , but it didn't work. 在keyup函数中没有用于此的选项，我已经尝试过setTimeout ，可是它没有用。 spa
How can I do that? 我怎样才能作到这一点？ .net
