Trigger jQuery Autocomplete manually
提问by TheFrack
I'm using jQuery UI Autocomplete with some AJAX (the data isn't pulled until after they stop typing). I would like to make it so once the data is found, Autocomplete will then pop-up as a search result. This works, however only when I start typing again (the dropdown doesn't trigger until I type because it's not initialized until after I stop typing).
我正在使用带有一些 AJAX 的 jQuery UI 自动完成功能（直到他们停止输入后才会提取数据）。我想这样做，一旦找到数据，自动完成就会作为搜索结果弹出。这有效，但是只有当我再次开始输入时（下拉菜单在我输入之前不会触发，因为它直到我停止输入后才被初始化）。
My code:
我的代码：
var availableTags = [
"Perl",
"PHP",
"Python",
"Ruby"
];
$('input#mainSearchBox').autocomplete({
source: availableTags,
minLength: 0
});
$('input#mainSearchBox').data('autocomplete').menu.active;
The last part was an attempt to activate autocomplete, but it fails.
最后一部分是尝试激活自动完成，但失败了。

You can use the following script to toggle the autocomplete manually:
您可以使用以下脚本手动切换自动完成：
var textbox = $('input#mainSearchBox');
var autocompleteBox = textbox.autocomplete('widget');
// toggle the autocomplete widget
autocompleteBox.is(':hidden') ?
textbox.autocomplete('search', textbox.val()).focus() :
autocompleteBox.hide();
This code can be found in the source of the combobox exampleon the jquery autocomplete demo site (lines 127-141).
此代码可以在 jquery 自动完成演示站点上的组合框示例的源代码中找到（第 127-141 行）。
