jQuery实现点击水纹波动动画

网络编程 2021-07-04 21:04www.168986.cn编程入门
今天要为大家绍一款由jquery实现的鼠标单击出现水波特效。用鼠标点击页面,你可以看到页面不断出面水波纹效果。然后水波纹渐渐消失。效果非常不错

jQuery点击水纹波动动画原理:

    1.在需要实现水波纹效果的标签中添加<XXX class="ripple-wrapper"></XXX>
    2.代码会定位 鼠标相对 与 标签的位置，以鼠标点为圆心画圆
    3.圆的半径 可以自定义(默认为标签的最大宽或高度)
    4.圆点颜色，和动画时间等可以自行修改内部代码，或直接 调用 $().css({})方法 进行覆盖

ripple-wrapper.js

$(function(){
  $(".ripple-wrapper").css(
    {
  "position": " absolute",
  "": " 0",
  "left": " 0",
  "z-index": " 1",
  "width": " 100%",
  "height": " 100%",
  "overflow": " hidden",
  "border-radius": " inherit",
  "pointer-events": " none"
  });
    $(".ripple-wrapper").parent().click(function(e){
     var ripple_obj=$(this).find(".ripple-wrapper");
     if(ripple_obj.find("div").length){ripple_obj.find("div").remove();}
     ripple_obj.prepend("<div></div>");
     var ripple_div=ripple_obj.find("div");
     ripple_div.css(
       {
  "display": " block",
  "background": " rgba(255, 255, 255, 0.7)",
  "border-radius": " 50%",
  "position": " absolute",
  "-webkit-transform": " scale(0)",
  "transform": " scale(0)",
  "opacity": " 1",
  "transition": " all 0.7s",
  "-webkit-transition": " all 0.7s",
  "-moz-transition": " all 0.7s",
  "-o-transition": " all 0.7s",
  "z-index": " 1",
  "overflow": " hidden",
  "pointer-events": " none"
    });
     var R= parseInt(ripple_obj.outerWidth());/默认半径为ripple-wrapper宽/
     if(parseInt(ripple_obj.outerWidth())<parseInt(ripple_obj.outerHeight())){
         R= parseInt(ripple_obj.outerHeight());/如果高度大于宽半径为ripp，le-wrapper高/
     }
      ripple_div.css({"width":(R2)+"px","height":(R2)+"px","": (e.pageY -ripple_obj.offset(). - R)+'px', "left": ( e.pageX -ripple_obj.offset().left -R)+'px',"transform":"scale(1)", "-webkit-transform":"scale(1)","opacity":"0"});;
    }); 
    
    });
