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：

1 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>
