jQuery autocomplete minLength
提问by Robin Maben
The autocomplete never fires on first character entered but 2nd. Although after using back-space it works for the minLength = 1. Also, the selectFirst:truenever defaults to first item in the array on page load.
自动完成永远不会在输入的第一个字符上触发，而是在第二个字符上触发。虽然在使用退格后它适用于minLength = 1。此外，selectFirst:true永远不会默认为页面加载时数组中的第一项。
$().ready(function (){
$('#CompanyName').autocomplete({
source: companyNames,
select: SetLocations,
selectFirst :true,
minLength: 0 //corrected as suggested, but still no change
});
});
Has anybody faced this behavior before. I'm clueless since I haven't any global settings/defaults.
有没有人遇到过这种行为。我一无所知，因为我没有任何全局设置/默认值。

You have a few syntactical errors, the document.readyhandler is missing a brace (and is deprecated anyway) and a comma in your options, it should look like this:
您有一些语法错误，document.ready处理程序缺少大括号（无论如何都已弃用）和选项中的逗号，它应该如下所示：
$(function() {
$('#CompanyName').autocomplete({
source: companyNames,
select: SetLocations,
selectFirst: true, //here
minLength: 0
});
});
Also, autocomplete activates afterminLengthcharacters, if you want it immediately, use 0, from the docs:
此外，自动完成在minLength字符后激活，如果您想要立即使用0，请使用, from the docs：
minLength: The minimum number of characters a user has to type before the Autocomplete activates. Zero is useful for local data with just a few items. Should be increased when there are a lot of items, where a single character would match a few thousand items.
minLength：在自动完成激活之前用户必须键入的最小字符数。零对于只有几个项目的本地数据很有用。当有很多项目时应该增加，其中单个字符将匹配几千个项目。
