我正在创建一个js文件,当您单击对象时,该文件会产生波纹触摸效果。我想为html代码中的元素分配一个类,该元素只是像#f6ac32这样的颜色代码,然后在Javascript/jQuery中创建一个函数,该函数可以挑选该颜色代码并从中创建一个变量,以便以后使用使用(更改波纹效果的颜色)。这可能吗?
这是我所做的(查看$('。ripple')。mousedown(function)中的注释):
$(document).ready(function() {
var rplObj,
x,
y,
ink,
color,
rplDelTimer;
//fade out ripple when unclicked
$('.ripple').mouseup(function() {
$('.ink').css({'opacity':'0'});
delRipple();
})
//Delete ripple element one second after last click
function delRipple() {
rplDelTimer = setTimeout(function() {
$('.ink').remove();
}, 1000)
}
$('body').mousemove(function(e){
//update mouse coordinates when it is moved
x = e.pageX;
y = e.pageY;
})
$('.ripple').mousedown(function(){
rplObj = $(this);
color = "#FFF"; //I want this to dynamically change depending on the class written in html
rippleClosed();
})
function rippleClosed() {
rplObj.prepend('<span class="ink"></span>'); //create ripple
ink = rplObj.find('.ink'); //create variable for ink span
ink.css('background',color); //set ripple color to color variable
//set diameter of ripple
if(!ink.height() && !ink.width()) {
//set diameter to parents width/height (whichever is larger)
d = Math.max(rplObj.outerWidth(), rplObj.outerHeight());
ink.css({height: d, width: d});
}
//set coordinates of ripple using position of mouse defined earlier
x = x - rplObj.offset().left - ink.width()/2;
y = y - rplObj.offset().top - ink.height()/2;
//set the position and animate the expansion
ink.css({top: y+'px', left: x+'px'}).css({'transform':'scale(1.8)'});
//reset ripple deletion timer
clearTimeout(rplDelTimer);
}
})
div {
background: #199ee3;
width: 300px;
height: 100px;
}
.ripple {
position: relative;
overflow: hidden;
}
.ink {
position: absolute;
border-radius: 100%;
opacity: .4;
transform: scale(0);
-moz-transition: all 1s ease;
-o-transition: all 1s ease;
-webkit-transition: all 1s ease;
transition: all 1s ease;
}

最佳答案
不要使用类,请使用data attributes。您可以通过这种方式将各种任意信息直接存储在DOM节点上。
$('div').on('click', function () {
var ripple = $(this).data('ripple');
alert(ripple);
});
div {
background: #199ee3;
width: 300px;
height: 100px;
}
<div data-ripple="#FFF"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
