Prinsip animasi riak air klik JQuery:

1. Tambahkan
pada tag yang perlu mencapai kesan riak air 2. Kod akan meletakkan tetikus secara relatif kepada label dan melukis bulatan dengan titik tetikus sebagai pusat
3. Jejari bulatan boleh disesuaikan (lalai ialah lebar atau ketinggian maksimum label)
4. Anda boleh mengubah suai kod dalaman untuk warna titik, masa animasi, dsb., atau terus memanggil kaedah $().css({}) untuk menulis ganti

ripple-wrapper.js

$(function(){
  $(".ripple-wrapper").css(
    {
  "position": " absolute",
  "top": " 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",

  "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*/
     }
