bootstrap typeahead - changing source
提问by Tzury Bar Yochay
I looking for a way to change sourcefor typeahed.
我正在寻找一种改变sourcetypeahed 的方法。
For instance, assume I have the following 2 lists, and depend on the case, I'd like to have the typeahead workingin with a different source.
例如，假设我有以下 2 个列表，并且视情况而定，我希望预先输入使用不同的来源。
var list1 = ["this", "is", "first", "list"],
list2 = ["second", "list", "comes", "here"];
$("selector").typeahead({source: list1})
Then, when I do
然后，当我做
$("selector").typeahead({source: list2})
and start typing into the input box, the first list appears underneath the new one.
并开始在输入框中输入，第一个列表出现在新列表的下方。
I tried doing
我试着做
$("selector")
.removeData()
.typeahead({source: list2})
Yet, it has no effect.
然而，它没有效果。

None of these answers worked for me when using the Bootstrap-3-Typeaheadlibrary. I was able to update the source by destroy the initialized typeahead and re initializing it with a new source:
使用Bootstrap-3-Typeahead库时，这些答案都不适合我。我能够通过销毁初始化的预先输入并使用新源重新初始化它来更新源：
$(".typeahead").typeahead("destroy");
$(".typeahead").typeahead({ source: result });

Unfortunately, the accepted answer didn't work for me. It could be an issue with newer versions of the library. For me, data('typeahead') isn't defined - instead there is data('ttTypeahead') and data('ttAttrs'). Neither of those has a source attribute.
不幸的是，接受的答案对我不起作用。较新版本的库可能存在问题。对我来说，data('typeahead') 没有定义——而是有 data('ttTypeahead') 和 data('ttAttrs')。这些都没有源属性。
After some code reading I came up with this:
$('selector').data('ttTypeahead').dropdown.datasets[0].source = mySourceFunction
经过一些代码阅读后，我想出了这个：
$('selector').data('ttTypeahead').dropdown.datasets[0].source = mySourceFunction
And it seems to work. There might be instances where more than one dataset is defined, though.
它似乎有效。但是，可能存在定义了多个数据集的情况。
