jQuery實現點擊水紋波動動畫
編輯：關於JavaScript
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());/*如果高度大於寬半徑為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"});;
});
});
