Prinsip animasi riak air klik JQuery:
1. Tambahkan 5c8b9de9fb73f56628b30e4b50c5fd36da7a5c458c43e8ac4398bd2378cdb6be
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", "-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":(R*2)+"px","height":(R*2)+"px","top": (e.pageY -ripple_obj.offset().top - R)+'px', "left": ( e.pageX -ripple_obj.offset().left -R)+'px',"transform":"scale(1)", "-webkit-transform":"scale(1)","opacity":"0"});; }); });
