一、描述
1.1 应用场景:想要页面随意点击的时候页面能够弹出炫彩的字体,并且希望鼠标悬浮的时候背景能够动态变化,大屏展示的时候效果炫酷。
1.2 功能介绍:鼠标点击炫彩效果是无论是cpt还是frm模板,页面展示的时候鼠标任意点击不仅不影响页面功能使用,还能够弹出炫彩的字体;鼠标悬浮炫彩效果多应用于大屏动态背景的效果,当鼠标不悬浮在屏幕上面的时候背景是动态变化的,鼠标悬浮在页面上时有汇聚的效果,通过演示这个模板,能够熟练掌握这一系列的相关需求。
二、示例
2.1 鼠标点击炫彩字体提示效果1、在模板web属性添加加载结束事件,如下代码:代码解释:a数组里面存储的是每次点击循环展示的内容,css里面写的是一些样式设置。var a_idx = 0;
jQuery(document).ready(function ($) {
$("body").click(function (e) {
console.log("xxxxxx")
var a = new Array("❤富强❤", "❤民主❤", "❤文明❤", "❤和谐❤", "❤自由❤", "❤平等❤", "❤公正❤", "❤法治❤", "❤爱国❤", "❤敬业❤", "❤诚信❤", "❤友善❤");
var $i = $("").text(a);
a_idx = (a_idx + 1) % a.length;
var x = e.pageX,
y = e.pageY;
$i.css({
"z-index": 999999999999999999999999999999999999999999999999999999999999999999999,
"top": y - 20,
"left": x,
"position": "absolute",
"font-weight": "bold",
"color": "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + ")"
//Math.random()返回介于 0(包含) ~ 1(不包含) 之间的一个随机数
});
$("body").append($i);
$i.animate({
"top": y - 180,
"opacity": 0
},
1500,
function () {
$i.remove();
});
});
});2.2 动态背景、鼠标悬浮粒子汇聚效果1、在模板web属性添加加载结束事件,如下代码:代码解释:主要是看return里面返回的信息是悬浮背景粒子的透明度、颜色以及粒子的个数设置。function() {
function o(w, v, i) {
return w.getAttribute(v) || i
}
function j(i) {
return document.getElementsByTagName(i)
}
function l() {
var i = j("script"),
w = i.length,
v = i;
return {
l: w,
z: o(v, "zIndex", 0),
o: o(v, "opacity", 0.8),//粒子的透明度
c: o(v, "color", "13,100,273"),//粒子的颜色设置
n: o(v, "count", 300)//粒子的个数
}
}
function k() {
r = u.width = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth,
n = u.height = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight
}
function b() {
e.clearRect(0, 0, r, n);
var w = .concat(t);
var x, v, A, B, z, y;
t.forEach(function(i) {
i.x += i.xa,
i.y += i.ya,
i.xa *= i.x > r || i.x < 0 ? -1 : 1,
i.ya *= i.y > n || i.y < 0 ? -1 : 1,
e.fillRect(i.x - 0.5, i.y - 0.5, 1, 1);
for (v = 0; v < w.length; v++) {
x = w;
if (i !== x && null !== x.x && null !== x.y) {
B = i.x - x.x,
z = i.y - x.y,
y = B * B + z * z;
y = x.max / 2 && (i.x -= 0.03 * B, i.y -= 0.03 * z), A = (x.max - y) / x.max, e.beginPath(), e.lineWidth = A / 2, e.strokeStyle = "rgba(" + s.c + "," + (A + 0.2) + ")", e.moveTo(i.x, i.y), e.lineTo(x.x, x.y), e.stroke())
}
}
w.splice(w.indexOf(i), 1)
}),
m(b)
}
var u = document.createElement("canvas"),
s = l(),
c = "c_n" + s.l,
e = u.getContext("2d"),
r,
n,
m = window.requestAnimationFrame || window.webkitRequestAnimationFrame || window.mozRequestAnimationFrame || window.oRequestAnimationFrame || window.msRequestAnimationFrame ||
function(i) {
window.setTimeout(i, 1000 / 45)
},
a = Math.random,
f = {
x: null,
y: null,
max: 20000
};
u.id = c;
u.style.cssText = "position:fixed;top:0;left:0;z-index:" + s.z + ";opacity:" + s.o;
j("body").appendChild(u);
k(),
window.onresize = k;
window.onmousemove = function(i) {
i = i || window.event,
f.x = i.clientX,
f.y = i.clientY
},
window.onmouseout = function() {
f.x = null,
f.y = null
};
for (var t = , p = 0; s.n > p; p++) {
var h = a() * r,
g = a() * n,
q = 2 * a() - 1,
d = 2 * a() - 1;
t.push({
x: h,
y: g,
xa: q,
ya: d,
max: 6000
})
}
setTimeout(function() {
b()
},
100)
} ();
