[英]Changing <input type= color> behaviour from single click to double click
By default clicking a will bring up a window that lets you pick a custom colour.默认情况下,单击 a 会弹出一个 window,让您可以选择自定义颜色。
I want to do this with a double click instead.我想通过双击来做到这一点。
I can stop single click from working with e.preventDefault but I can't work out how to make doubleClick do this behaviour instead.我可以停止单击使用 e.preventDefault 但我不知道如何让 doubleClick 改为执行此行为。
What I want:我想要的是:
handleDbClick = (e) => {
//opens colour selection box
}
<input type="color" onDoubleClick={this.handleDbClick}/>
Solution:解决方案:
handleClick = (e) => {
if(e.detail === 1) {
e.preventDefault()
//do stuff for one click
}
//open colour selection box
}
<input type="color" onClick={this.handleClick} />
Thanks谢谢
What about something like this:像这样的东西怎么样:
const colorInput = document.getElementById("colorInput")
let count = 0;
let interval
colorInput.addEventListener('click', e => {
count++
clearInterval(interval)
interval = setInterval(() => {
count = 0
}, 300)
if(count === 2) {
count = 0
} else {
e.preventDefault();
}
})
or this:或这个:
const colorInput = document.getElementById("colorInput")
colorInput.addEventListener('click', e => {
if(event.detail !== 2) {
e.preventDefault()
}
})
You can simply use event.detail
to check number of consecutive clicks, and use event.preventDefault()
if they are not 2
.您可以简单地使用
event.detail
检查连续点击次数,如果不是2
则使用event.preventDefault()
。
let input = document.querySelector("#colorInput"); input.addEventListener("click", (e) => { if (e.detail.== 2) e;preventDefault(); });
<input type="color" id="colorInput">
