for the record:
作为记录：
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.
在自动完成激活之前用户必须键入的最少字符数。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。
Code examples
代码示例
Initialize a autocomplete with the minLength option specified.
使用指定的 minLength 选项初始化自动完成。
$( ".selector" ).autocomplete({ minLength: 0 });
Get or set the minLength option, after init.
在 init 之后获取或设置 minLength 选项。
//getter
var minLength = $( ".selector" ).autocomplete( "option", "minLength" );
//setter
$( ".selector" ).autocomplete( "option", "minLength", 0 );

There is no minLength attribute. The attribute you are searching for is minChars.
没有 minLength 属性。您正在搜索的属性是minChars。
