jQuery點擊水紋波動動畫原理:
1.在需要實現水波紋效果的標簽中添加<XXX class="ripple-wrapper"></XXX>
2.代碼會定位 鼠標相對 與 標簽的位置，以鼠標點為圓心畫圓
3.圓的半徑 可以自定義(默認為標簽的最大寬或高度)
4.圓點顏色，和動畫時間等可以自行修改內部代碼，或直接 調用 $().css({})方法 進行覆蓋
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());/*默認半徑為ripple-wrapper寬*/ if(parseInt(ripple_obj.outerWidth())<parseInt(ripple_obj.outerHeight())){ R= parseInt(ripple_obj.outerHeight());/*如果高度大于寬半徑為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"});; }); });HTML
