Set selected value of typeahead
提问by gpasse
I am using the twitter bootstrap typeahead.
我正在使用twitter bootstrap typeahead。
I have customized the typehead so I can select a pair value/label
我已经自定义了打字头，所以我可以选择一对值/标签
$.each(data.medicines,function(index,values){
_med=new Object()
_med.value=values.LYF
_med.id=values.LYF_NUMER
_medicines.push(_med)
})
//Fill typeahead with data
$('.typeahead').typeahead({
// note that "value" is the default setting for the property option
source:_medicines,
onselect: function(obj) { showdetails(obj) }
})
How can I set the selected value using Javascript ?
如何使用 Javascript 设置选定的值？
For exemple $("#mytypehead").val(43);

According to the typeahead.jsdocumentation on GitHub(which is much more detailed than the bootstrap-typeahead.jsdocs in Twitter Bootstrap):
根据GitHub 上的typeahead.js文档（比Twitter Bootstrap 中的bootstrap-typeahead.js文档详细得多）：
jQuery#typeahead('setQuery', query)
Sets the current query of the typeahead. This is always preferable to using
$("input.typeahead").val(query), which will result in unexpected behavior. To clear the query, simply set it to an empty string.
jQuery#typeahead('setQuery', 查询)
设置预先输入的当前查询。这总是比使用 更可取
$("input.typeahead").val(query)，后者会导致意外行为。要清除查询，只需将其设置为空字符串。
2016 Update (setQuery does not exist anymore) :
2016 更新（setQuery 不再存在）：
jQuery#typeahead('val', val) Sets the value of the typeahead. This should be used in place of jQuery#val.
jQuery#typeahead('val', val) 设置预先输入的值。这应该用来代替 jQuery#val。
$('.typeahead').typeahead('val', myVal);
