我在Semplice论坛上问过这个问题,但他们很难说我如何实现我想要的东西,所以我决定在这里问一下。看起来相当简单。我想使用此代码:https://codepen.io/chrisboon27/pen/rEDIC并将其应用于我的背景图片。
以下是我在我的网站中实施的代码:
.cover-76 .cover-image {
background:url('http://nicolebelcher.com/wp-
content/uploads/2016/05/background1.jpg') -25px -50px;
position:fixed ;
top:0;
width:100%;
z-index:0;
height:100%;
background-size: calc(100% + 50px);
}
的javascript:
$(document).re`enter code here`ady(function() {
var movementStrength = 70;
var height = movementStrength / $(window).height();
var width = movementStrength / $(window).width();
$(".cover-76 .cover-image").mousemove(function(e){
var pageX = e.pageX - ($(window).width() / 2);
var pageY = e.pageY - ($(window).height() / 2);
var newvalueX = width * pageX * -1 - 25;
var newvalueY = height * pageY * -1 - 50;
$('.cover-76 .cover-image').css("background-position",
newvalueX+"px "+newvalueY+"px");
});
});
我可能做错了什么?我认为Semplice JS可能会阻止它或什么?

请你检查这个plunker

$(document).ready(function() {
var movementStrength = 70;
var height = movementStrength / $(window).height();
var width = movementStrength / $(window).width();
$(".cover-image").mousemove(function(e){
var pageX = e.pageX - ($(window).width() / 2);
var pageY = e.pageY - ($(window).height() / 2);
var newvalueX = width * pageX * -1 - 25;
var newvalueY = height * pageY * -1 - 50;
$('.cover-image').css("background-position",
newvalueX+"px "+newvalueY+"px");
});
});
这是你真的想要吗?
