Question

我试图让特定的.div在点击时更改背景颜色。由于用户可以更改颜色，因此颜色必须是变量，并且应该在.ready（）时运行。

我正在使用CSS变量' - main-color'作为我想要更改背景颜色的变量，但是在使用'$（this）'时我似乎无法找到解决它的jQuery方法。

是否有使用.click（）函数应用自定义CSS属性/变量的特定方法？

$(document).ready(function(){

	// CREATE GRID
	for (i = 0; i<1152; i++) {
		var board = document.createElement('div');
		board.className = 'grid';
		board.addId = 'color'
		document.getElementById('container').appendChild(board);
	};
	// END CREATE GRID

  	// HOVER AND CLICK FUNCTION //
  	    $('#color-picker').colorpicker().on('changeColor', function(ev){
    var choice = ev.color.toHex();
        document.body.style.setProperty('--main-color', choice);
	});

  	$('.grid').hover(function(){
        $(this).click(function(){
        	$(this).css('background-color', 'var(--main-color)');
		});
	});
	// END HOVER AND CLICK FUNCTION


});

	background-color: #222;
	margin: 0;
	padding: 0;
	box-sizing: border-box;

Answer 1

将颜色指定给一个类，然后切换该类。

＆＃13;

document.querySelector('div').addEventListener('click',function() {
  this.classList.toggle('color');
})

＆＃13;

body {
  --main-color: #000;
}
.color {
  background-color: var(--main-color);
  color: white;
}

＆＃13;

<div>div</div>

＆＃13;

或者使用jquery ......

＆＃13;

$(function() {
  $('div').on('click',function() {
    $(this).toggleClass('color');
  });
});

＆＃13;

body {
  --main-color: #000;
}
.color {
  background-color: var(--main-color);
  color: white;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div>div</div>

＆＃13;
