最終效果如下圖所示,pc和移動端都可以展示的,調用方法也很簡單,開始調用:loading.baosight.showPageLoadingMsg(false),alse代表不現實加載說明,true展示加載說明.調用完成后調用:loading.baosight.hidePageLoadingMsg(),在整個代碼里有兩個文件,一個是js文件,一個是css文件。切記不要忘記引入jquery.js
css文件
#_loadMsg{ display: inline-block; width: 100%; text-align: center; line-height: 45; padding-left: 20px; display : none; } #_loading_div { vertical-align: middle; display: inline-block; width: 100%; height: 100%; margin: 0 auto; text-align: center; position: absolute; z-index: 3; line-height: 40; opacity: 0.5; display : none; background: #CCCCCC; } #_loading_div span { display: inline-block; width: 10px; height: 40px; animation-name: scale; -webkit-animation-name: scale; -moz-animation-name: scale; -ms-animation-name: scale; -o-animation-name: scale; animation-duration: 1.2s; -webkit-animation-duration: 1.2s; -moz-animation-duration: 1.2s; -ms-animation-duration: 1.2s; -o-animation-duration: 1.2s; animation-iteration-count: infinite; -webkit-animation-iteration-count: infinite; -moz-animation-iteration-count: infinite; -ms-animation-iteration-count: infinite; -o-animation-iteration-count: infinite; } span.item-1 { background: #2ecc71; } span.item-2 { background: #3498db; } span.item-3 { background: #9b59b6; } span.item-4 { background: #e67e22; } span.item-5 { background: #c0392b; } span.item-6 { background: #e74c3c; } span.item-7 { background: #e74c8c; } .item-1 { animation-delay: -1s; -webkit-animation-delay: -1s; -moz-animation-delay: -1s; -ms-animation-delay: -1s; -o-animation-delay: -1s; } .item-2 { animation-delay: -0.9s; -webkit-animation-delay: -0.9s; -moz-animation-delay: -0.9s; -ms-animation-delay: -0.9s; -o-animation-delay: -0.9s; } .item-3 { animation-delay: -0.8s; -webkit-animation-delay: -0.8s; -moz-animation-delay: -0.8s; -ms-animation-delay: -0.8s; -o-animation-delay: -0.8s; } .item-4 { animation-delay: -0.7s; -webkit-animation-delay: -0.7s; -moz-animation-delay: -0.7s; -ms-animation-delay: -0.7s; -o-animation-delay: -0.7s; } .item-5 { animation-delay: -0.6s; -webkit-animation-delay: -0.6s; -moz-animation-delay: -0.6s; -ms-animation-delay: -0.6s; -o-animation-delay: -0.6s; } .item-6 { animation-delay: -0.5s; -webkit-animation-delay: -0.5s; -moz-animation-delay: -0.5s; -ms-animation-delay: -0.5s; -o-animation-delay: -0.5s; } .item-7 { animation-delay: -0.4s; -webkit-animation-delay: -0.4s; -moz-animation-delay: -0.4s; -ms-animation-delay: -0.4s; -o-animation-delay: -0.4s; } @-webkit-keyframes scale { 0%, 40%, 100% { -moz-transform: scaleY(0.2); -ms-transform: scaleY(0.2); -o-transform: scaleY(0.2); -webkit-transform: scaleY(0.2); transform: scaleY(0.2); } 20%, 60% { -moz-transform: scaleY(1); -ms-transform: scaleY(1); -o-transform: scaleY(1); -webkit-transform: scaleY(1); transform: scaleY(1); } } @-moz-keyframes scale { 0%, 40%, 100% { -moz-transform: scaleY(0.2); -ms-transform: scaleY(0.2); -o-transform: scaleY(0.2); -webkit-transform: scaleY(0.2); transform: scaleY(0.2); } 20%, 60% { -moz-transform: scaleY(1); -ms-transform: scaleY(1); -o-transform: scaleY(1); -webkit-transform: scaleY(1); transform: scaleY(1); } } @-ms-keyframes scale { 0%, 40%, 100% { -moz-transform: scaleY(0.2); -ms-transform: scaleY(0.2); -o-transform: scaleY(0.2); -webkit-transform: scaleY(0.2); transform: scaleY(0.2); } 20%, 60% { -moz-transform: scaleY(1); -ms-transform: scaleY(1); -o-transform: scaleY(1); -webkit-transform: scaleY(1); transform: scaleY(1); } } @keyframes scale { 0%, 40%, 100% { -moz-transform: scaleY(0.2); -ms-transform: scaleY(0.2); -o-transform: scaleY(0.2); -webkit-transform: scaleY(0.2); transform: scaleY(0.2); } 20%, 60% { -moz-transform: scaleY(1); -ms-transform: scaleY(1); -o-transform: scaleY(1); -webkit-transform: scaleY(1); transform: scaleY(1); } }
js文件
var loading = { baosight : { showPageLoadingMsg : function(showMessage){ if($("#_loading_div").length == 0){ $("body").append('<div id="_loading_div"><span class="item-1"></span><span class="item-2"></span><span class="item-3"></span><span class="item-4"></span><span class="item-5"></span><span class="item-6"></span><span class="item-7"></span></div>'); } if($("#_loadMsg").length == 0){ $("body").append('<div id="_loadMsg">正在加載,請稍候... ...</div>'); } if(showMessage == true || showMessage == "true" ){ $("#_loadMsg").show(); } $("#_loading_div").show(); }, hidePageLoadingMsg :function() { $("#_loading_div").hide(); $("#_loadMsg").hide(); } } }
