如何 jquery 自动完成 json 结果?
How to jquery autocomplete json results?
我的代码有两个问题:
首先是,json 中的搜索结果仅在我删除文本输入时出现,而不是在我输入时出现……就像我需要的那样。第二个是,当我点击其中一个结果显示它时,我需要文本转到输入文本的值。
我该怎么做?

根据自动完成 docs,它不适用于 json 数据,仅适用于数组。
像这样尝试一些想法,应该有效。
var arr = ['project1', 'another project', 'more one project'];
$("#project").autocomplete({
minLength: 0,
source: arr,
focus: function( event, ui ) {
$("#project").val( ui.item.label );
return false;
}
});
要在擦除字段时隐藏结果,您应该像这样设置 minLengh <= 1:
$project.autocomplete({
minLength: 1,
source: projects,
focus: function( event, ui ) {
$project.val( ui.item.label );
return false;
}
});
如果您想在后端搜索数据,我认为您应该考虑使用选项将数据过滤为查询字符串,请查看此文档部分:
String: When a string is used, the Autocomplete plugin expects that
string to point to a URL resource that will return JSON data. It can
be on the same host or on a different one (must provide JSONP). The
Autocomplete plugin does not filter the results, instead a query
string is added with a term field, which the server-side script should
use for filtering the results. For example, if the source option is
set to "http://example.com" and the user types foo, a GET request
would be made to http://example.com?term=foo. The data itself can be
in the same format as the local data described above.
