为什么更改div内的颜色不起作用? [英] Why change the color inside the div does not work?

问题描述

具有id的div是单击的，具有class的div是未单击的.通过单击div，我想更改颜色.如果div类中的颜色输入不起作用，如果不在div类中，则它正常工作.我该如何解决?

Div with the id is clicking, the div with class is not clicking. By clicking div I want to change the color. If the color input within the div class is not working, if it is out of div class it works normally. How do I fix this?

var div = document.getElementsByTagName("div");
var divCount = div.length;
var clickedDivId;

for (var i = 0; i < divCount; i += 1) {
    div[i].onclick = function(e) {
        if (e.target.id) alert(this.id);
		clickedDivId = this.id;
        e.stopPropagation();
    };
}  

function BackgroundColor(){
  var x = document.getElementsByClassName("backgroundcolor")[0].value;
  document.getElementById(clickedDivId).style.backgroundColor = x;
}

#divid{
  width: 450px;
  height: 170px;
  margin: 10px;
  padding: 10px;
  background-color: blue;
}
.divclass{
  width: 450px;
  height: 170px;
  margin: 10px;
  padding: 10px;
  background-color: blue;
}

<div  class="divclass">
     <input type="color" class="backgroundcolor" onchange="BackgroundColor()">
</div>
<div  id="divid"></div>

推荐答案

function BackgroundColor(){

  var x = document.getElementById("backgroundcolor1").value;
   
  document.getElementById("clickedDivId").style.backgroundColor = x;
}

#divid{
  width: 450px;
  height: 170px;
  margin: 10px;
  padding: 10px;
  background-color: blue;
}
.divclass{
  width: 450px;
  height: 170px;
  margin: 10px;
  padding: 10px;
  background-color: blue;
}

<div id="clickedDivId" class="divclass">
     <input type="color" id="backgroundcolor1" onclick="BackgroundColor()">
</div>
<div  id="divid"></div>

最好使用ID.我想这就是你想要的. 通过不断改变颜色，背景也会改变.

It is better to use ID. I guess this is what you want. By keep changing the color the background will change as well.
