我在我的应用程序中具有以下jquery自动完成功能(https://github.com/devbridge/jQuery-Autocomplete)
但是速度非常慢-渲染需要将近4秒钟。我已经安装了debugbar,时间轴显示启动过程几乎耗时3s,应用程序耗时1s,实际数据库查询为44ms。
这是我的jQuery自动完成实现:
window.locationAutoCompleteSettings = {
serviceUrl: "/location-lookup",
minChars: 2,
paramName: "term",
showNoSuggestionNotice: false,
onSearchStart: function (query) {
$(this).closest(".js-clear-input").find(".js-clear-input-trigger").addClass("clear-input-spinner")
},
onSearchComplete: function (query) {
$(this).closest(".js-clear-input").find(".js-clear-input-trigger").removeClass("clear-input-spinner")
},
transformResult: function (response) {
var data = JSON.parse(response);
return {
suggestions: $.map(data, function (item) {
return {
value: item.name,
data: item.id
}
})
};
},
onSelect: function (suggestion) {
var e = $(this).closest(".js-lookup-container").find(".js-location-id");
e.val(suggestion.data);
var f = suggestion.value, b = $(".js-location-description");
if (b.length && b.val() == "") {
b.val(f).trigger("change")
}
}
};
$(".js-location-lookup").autocomplete(window.locationAutoCompleteSettings);
这是我的控制器方法:
public function locationLookup(Request $request)
{
$term = $request->input('term');
$locations = $this->locationRepository->getByName($term)->get();
return response()->json($locations);
}
为了记录,我正在Windows 10机器上的php 7.4上在Homestead上运行它
任何想法,我怎么能对此进行调整,因为就目前而言,它不是很有用?
可以通过限制记录和限制要获取的数据来进行小幅改进,如下所示-
public function locationLookup(Request $request)
{
$term = $request->input('term');
$locations = $this->locationRepository->getByName($term)->take(10)->get(['id', 'name']);
return response()->json($locations);
}
读取少量数据有点麻烦,我希望它可以提高性能。
所以我已经安装了https://github.com/winnfsd/vagrant-winnfsd
$ vagrant plugin install vagrant-winnfsd
如下更新Homestead.yaml:
folders:
- map: ~/code/project1
to: /home/vagrant/project1
type: "nfs"
运行
vagrant up --provision
现在启动已降低到500ms
