Your current selectors ( "quit_Modal" and 'btnClose') with no class . 当前没有类的选择器（“ quit_Modal”和“ btnClose”） . or identifier # signs will refer to tags, so the jQuery will search for tags with the name of <quit_Modal> and <btnClose> in your DOM. 或标识符#符号将指向标签，因此jQuery将在您的DOM中搜索名称为<quit_Modal>和<btnClose> <quit_Modal>标签。
You're missing the selectors sign (dot . and # ): 你错过了选择签名（点.和# ）：
$("#quit_Modal").modal('show');
$('.btnClose').trigger('click');
NOTE: The quit_Modal should be an id id="quit_Modal" . 注意： quit_Modal应该是一个id id="quit_Modal" 。
jQuery(document).ready(function(e) { $("#quit_Modal").modal('show'); setTimeout(function() { $('.btnClose').trigger('click'); }, 1000); });

Your selector is wrong. 您的选择器有误。
Instead of: 代替：
$("quit_Modal").modal('show');
$('btnClose').trigger('click');
use this: 用这个：
$(".quit_Modal").modal('show');
$('.btnClose').trigger('click');

$("quit_Modal").modal('show');
$('btnClose').trigger('click');
Both are class so first put dot(.) before it... 两者都是类，因此首先将dot（。）放在前面...
$(".quit_Modal").modal('show');
$('.btnClose').trigger('click');
