jQuery UI自动填充

我希望输入集中后立即显示选项.有这个设置吗?我尝试将minLength设置为0，但不起作用...它仍在等待按键.

I want the options to appear as soon as my input is focused. Is there a setting for that? I tried setting minLength to 0, but it doesn't work... it still waits for a keypress.

推荐答案

$("#yourField").bind('focus', function(){ $(this).autocomplete("search"); } );

由@HoldOffHunger启发，您还必须将minLength设置为0

As enlighted by @HoldOffHunger you must also set minLength to 0
