在许多时候,我们希望用户点击页面时会有一定的反馈(如浮现字幕、放烟花)。这次,我们来实现一下如何使用户点击页面时,弹出24字核心价值观。

创建clicker.js文件

在博客根目录往下找\themes\next\source\js文件夹,创建clicker.js,文件内容如下:

!function (e, t, a) {
function r() {
for (var e = 0; e < s.length; e++) s[e].alpha <= 0 ? (t.body.removeChild(s[e].el), s.splice(e, 1)) : (s[e].y--, s[e].scale += .004, s[e].alpha -= .013, s[e].el.style.cssText = "left:" + s[e].x + "px;top:" + s[e].y + "px;opacity:" + s[e].alpha + ";transform:scale(" + s[e].scale + "," + s[e].scale + ") rotate(45deg);background:" + s[e].color + ";z-index:99999");
requestAnimationFrame(r)
}

function n() {
var t = "function" == typeof e.onclick && e.onclick;
e.onclick = function (e) {
t && t(), o(e)
}
}

function o(e) {
var a = t.createElement("div");
a.className = "heart", s.push({
el: a,
x: e.clientX - 5,
y: e.clientY - 5,
scale: 1,
alpha: 1,
color: c()
}), t.body.appendChild(a)
}

function i(e) {
var a = t.createElement("style");
a.type = "text/css";
try {
a.appendChild(t.createTextNode(e))
} catch (t) {
a.styleSheet.cssText = e
}
t.getElementsByTagName("head")[0].appendChild(a)
}

function c() {
return "rgb(" + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + "," + ~~(255 * Math.random()) + ")"
}
var s = [];
e.requestAnimationFrame = e.requestAnimationFrame || e.webkitRequestAnimationFrame || e.mozRequestAnimationFrame || e.oRequestAnimationFrame || e.msRequestAnimationFrame || function (e) {
setTimeout(e, 1e3 / 60)
}, i(".heart{width: 10px;height: 10px;position: fixed;background: #f00;transform: rotate(45deg);-webkit-transform: rotate(45deg);-moz-transform: rotate(45deg);}.heart:after,.heart:before{content: '';width: inherit;height: inherit;background: inherit;border-radius: 50%;-webkit-border-radius: 50%;-moz-border-radius: 50%;position: fixed;}.heart:after{top: -5px;}.heart:before{left: -5px;}"), n(), r()
}(window, document);

/* 社会主体核心价值观效果 */
var a_idx = 0;
jQuery(document).ready(function ($) {
$("body").click(function (e) {
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 = $("<span/>").text(a[a_idx]);
a_idx = (a_idx + 1) % a.length;
var x = e.pageX,
y = e.pageY;
$i.css({
"z-index": 100000000,
"top": y - 20,
"left": x,
"position": "absolute",
"font-weight": "bold",
"color": "#ff6651"
});
$("body").append($i);
$i.animate({
"top": y - 180,
"opacity": 0
}, 1500, function () {
$i.remove();
});
});
});

然后保存。

修改_layout.swig

打开\themes\next\layout,找到_layout.swig,在<head>标签内插入以下代码:

2
<script src="https://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script><!--需要JQuery的支持-->
<script type="text/javascript" src ="/js/clicker.js" ></script>

随后可通过hexo s查看效果:
