I'm using the jquery autocomplete 1.0.2 extension by Dylan Verheul, Dan G. Switzer, Anjesh Tuladhar, Jörn Zaefferer. I am attempting to execute my own callback function when .show() and .hide() are called from within the autocomplete control. I haven't found any way for it to actually recognize my callback function. If anyone is familiar with this control and can help I would be greatly appreciative.

推荐答案

对不起，我没有任何简单的回答你的问题，我查了插件的源$ C ​​$ c和没有发现任何机制来让你想得到你想要的。我认为你必须要更新这个插件自己做，你想它的工作。

Sorry, I don't have any easy answer to your question, I checked the plugin source code and didn't find any mechanism to let you do want you want. I think you'll have to update this plugin yourself to make it work as you wish.

我们的想法是你的回调添加到选项参数，然后把这个插件使用这些回调。首先，你必须修改插件code。转到该负责显示/隐藏自动完成控制，创建该类的功能：

The idea is to add your callbacks to the options parameter and then make the plugin use these callbacks. First, you'll have to modify the plugin code. Go to the function that creates the class in charge of showing/hiding the autocomplete control :

$.Autocompleter.Select = function (options, input, select, config) {

如果您向下滚动，你可以看到，这个函数返回一个对象，显示（）和隐藏（）方法。您可以添加以下code：

If you scroll down, you can see that this function returns an object with show() and hide() methods. You can add the following code :

hide: function() {
    ...
    options.showCallback && options.showCallback(); // Invoke callback function if set
},
...
show: function() {
    ...
    options.hideCallback && options.hideCallback(); // Invoke callback function if set
},

最后，当你创建你自动完成，你应该添加您的回调您的选择：

Finally, when you create your autocomplete, you should add your callbacks to your options:

$("#myTextBox").autocomplete("http://...",
{
    showCallback : function() { /* do what you want here */ },
    hideCallback : function() { /* do what you want here */ }
});

没有测试所有，它只是一个快速和肮脏的解决方案。我希望这有助于。

Not tested at all, it's just a quick and dirty solution. I hope this helps.
