上面的答案是最好的!然而，当etype = 'click'时，它并没有为我在Firefox中触发鼠标事件。

所以，我修改了文档。createEvent到'MouseEvents'这就解决了这个问题。额外的代码是为了测试是否有其他代码干扰了事件，如果它被取消了，我会将其记录到控制台。

function eventFire(el, etype){
  if (el.fireEvent) {
    el.fireEvent('on' + etype);
  } else {
    var evObj = document.createEvent('MouseEvents');
    evObj.initEvent(etype, true, false);
    var canceled = !el.dispatchEvent(evObj);
    if (canceled) {
      // A handler called preventDefault.
      console.log("automatic click canceled");
    } else {
      // None of the handlers called preventDefault.
    } 
  }
}

比如一些简单的东西怎么样:

document.getElementById('elementID').click();

IE也支持。

使用jQuery可以节省大量空间。你只需要使用:

$('#myElement').trigger("click")

const Discord = require("discord.js");
const superagent = require("superagent");

module.exports = {
    name: "hug",
    category: "action",
    description: "hug a user!",
    usage: "hug <user>",
    run: async (client, message, args) => {
    let hugUser = message.mentions.users.first() 
    if(!hugUser) return message.channel.send("You forgot to mention somebody.");
    let hugEmbed2 = new Discord.MessageEmbed()
    .setColor("#36393F")
    .setDescription(`**${message.author.username}** hugged **himself**`)
    .setImage("https://i.kym-cdn.com/photos/images/original/000/859/605/3e7.gif")
     .setFooter(`© Yuki V5.3.1`, "https://cdn.discordapp.com/avatars/489219428358160385/19ad8d8c2fefd03fa0e1a2e49a2915c4.png")
  if (hugUser.id === message.author.id) return message.channel.send(hugEmbed2);
    const {body} = await superagent
    .get(`https://nekos.life/api/v2/img/hug`);

    let hugEmbed = new Discord.MessageEmbed()
    .setDescription(`**${message.author.username}** hugged **${message.mentions.users.first().username}**`)
    .setImage(body.url)
    .setColor("#36393F")
     .setFooter(`© Yuki V5.3.1`, "https://cdn.discordapp.com/avatars/489219428358160385/19ad8d8c2fefd03fa0e1a2e49a2915c4.png")
    message.channel.send(hugEmbed)
}
}

var elem = document.getElementById('mytest1');

// Simulate clicking on the specified element.
triggerEvent( elem, 'click' );

/**
 * Trigger the specified event on the specified element.
 * @param  {Object} elem  the target element.
 * @param  {String} event the type of the event (e.g. 'click').
 */
function triggerEvent( elem, event ) {
  var clickEvent = new Event( event ); // Create the event.
  elem.dispatchEvent( clickEvent );    // Dispatch the event.
}

document.getElementById("element").click()

只需从DOM中选择元素。该节点具有单击函数，您可以调用该函数。

Or

document.querySelector("#element").click()
