博客背景增加鼠标效果

一.背景特效添加跟随鼠标动态线条特效

方法1.安装Canvas-nest插件,此方法简单,安装完可设置代码颜色

方法2.源码无需插件

!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[w-1];return{l:w,z:o(v,"zIndex",-1),o:o(v,"opacity",0.5),c:o(v,"color","0,0,0"),n:o(v,"count",99)}}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=[f].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[v];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&&(x===f&&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")[0].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)}();

以上代码保存为canvas-nest.min.js文件,将canvas-nest.min.js文件,放到主题begin\js目录中,然后找到页脚footer.php文件里的并在这个代码前添加以下内容

<script type="text/javascript" src="<?php bloginfo('template_directory');?>/js/canvas-nest.min.js"></script>

js的路径是可以更改的

二.给网站添加鼠标点击红色数字或标语上升特效

把js代码直接加入footer.php中即可。

点击鼠标,红色随机数字上升特效代码

点击鼠标,红色标语上升特效代码

<script type="text/javascript">  
    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": 9999999999999999999999999999999999999999,                 "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();  
            });  
        });  
    });  
    </script>
