我只是想知道如何使用JavaScript来模拟对元素的单击。
目前我有:
function simulateClick(control) {
if (document.all) {
control.click();
} else {
var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window, 1, 12, 345, 7, 220, false, false, true, false, 0, null );
control.dispatchEvent(evObj);
}
}
<a href="http://www.google.com" id="mytest1">test 1</a><br>
<script type="text/javascript">
simulateClick(document.getElementById('mytest1'));
</script>
但它并没有起作用:(
什么好主意吗?
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 **${message.mentions.users.first().username}**`)
.setImage(body.url)
.setColor("#36393F")
.setFooter(`© Yuki V5.3.1`, "https://cdn.discordapp.com/avatars/489219428358160385/19ad8d8c2fefd03fa0e1a2e49a2915c4.png")
message.channel.send(hugEmbed)
}
}
[编辑2022]这个答案真的过时了。现代化。原始答案在底部。
使用元素。dispatchEvent使用新创建的所需类型的Event。
下面是一个使用事件委托的例子。
Fork这个stackblitz项目来玩它。
// Note: {bubbles: true} because of the event delegation ...
document.addEventListener(`click`, handle);
document.addEventListener(`virtualhover`, handle);
// the actual 'trigger' function
const trigger = (el, etype, custom) => {
const evt = custom ?? new Event( etype, { bubbles: true } );
el.dispatchEvent( evt );
};
// a custom event ;)
const vHover = new CustomEvent(`virtualhover`,
{ bubbles: true, detail: `red` });
setTimeout( _ =>
trigger( document.querySelector(`#testMe`), `click` ), 1000 );
function handle(evt) {
if (evt.target.id === `clickTrigger`) {
trigger(document.querySelector(`#testMe`), `click`);
}
if (evt.type === `virtualhover`) {
evt.target.style.color = evt.detail;
return setTimeout( _ => evt.target.style.color = ``, 1000 );
}
if (evt.target.id === `testMe`) {
document.querySelector(`#testMeResult`)
.insertAdjacentHTML(`beforeend`, `<p>One of us clicked #testMe.
It was <i>${evt.isTrusted ? `<b>you</b>` : `me`}</i>.</p>`);
trigger(
document.querySelector(`#testMeResult p:last-child`),
`virtualhover`,
vHover );
}
}
body {
font: 1.2rem/1.5rem verdana, arial;
margin: 2rem;
}
#testMe {
cursor: pointer;
}
p {
margin: 0.2rem 0;
}
<div id="testMe">
Test me can be clicked
</div>
<p><button id='clickTrigger'>Click #testMe</button></p>
<div id="testMeResult"></div>
老答案是:
这是我做的。这很简单，但很有效:
函数eventFire(el, etype){
if (el.fireEvent) {
埃尔。fireEvent('on' + etype);
}其他{
var evObj = document.createEvent('Events');
evObj。initEvent(etype, true, false);
el.dispatchEvent (evObj);
｝
｝
