說一下知識點:javascript
1.水球是echarts的插件echarts-liquidfill,官網下載-擴展下載中能夠拿到,git傳送陣https://github.com/ecomfe/echarts-liquidfillcss
2.水球上的數字是動態滾動效果,用的是插件countup, 還有適用於angular、vue、react的v2版本,npm傳送陣https://www.npmjs.com/package/countup.jshtml
3.星星評分是jq插件jquery.raty.js,傳送陣http://www.jq22.com/jquery-info6430vue
4.百度地圖自定義覆蓋物,本身按官網寫的,不怎麼完善java
/** * ComplexCustomOverlay 百度地圖 自定義覆蓋物(此例無文本,只添加icon) * params name: icon顯示時的title point: [lon, lat] * size: 覆蓋物大小 {w: 111, h: 200} * url: 覆蓋物背景圖片 * use: var marker = new ComplexCustomOverlay('truck', [truckLon, truckLat], { w: 23.8, h: 39.3 }, 'assets/logistics/truck.png') * map.addOverlay(marker); **/ function ComplexCustomOverlay(name, point, size, url) { this._point = new BMap.Point(point[0], point[1]); this._size = size; this._url = url; this._name = name; }; ComplexCustomOverlay.prototype = new BMap.Overlay(); ComplexCustomOverlay.prototype.initialize = function (map) { this._map = map; var div = this._div = document.createElement("div"); div.style.position = "absolute"; div.title = this._name; div.style.zIndex = BMap.Overlay.getZIndex(this._point.lat); div.style.width = this._size.w + 'px'; div.style.height = this._size.h + 'px'; div.style.background = 'url(' + this._url + ') center center no-repeat'; map.getPanes().markerPane.appendChild(div); return div; }; ComplexCustomOverlay.prototype.draw = function () { var map = this._map; var pixel = map.pointToOverlayPixel(this._point); this._div.style.left = pixel.x - this._size.w / 2 + 'px'; this._div.style.top = pixel.y - this._size.h / 2 + 'px'; }; ComplexCustomOverlay.prototype.show = function (cb) { if (this._div) { this._div.style.display = ''; if (cb) cb(); } }; ComplexCustomOverlay.prototype.hide = function (cb) { if (this._div) { this._div.style.display = 'none'; if (cb) cb(); } };
5.echarts圓環圖,很簡單,radius:[40%, 60%], 第一個是內圈,第二個是外圈,顯示的標籤是富文本設置的 須要echarts3.7以上,將標籤設置到導視線上react
{ type: 'pie', radius: ['40%', '50%'], avoidLabelOverlap: false, label: { normal: { show: true, padding: [0, -55], // 控制標籤移動 formatter: '{num|{d}%}\n{time|{b}}', rich: { // 富文本 num: { fontSize: 24, color: '#333', lineHeight: 40, align: 'center' }, time: { fontSize: 14, lineHeight: 40, color: '#999', align: 'center' } } }, emphasis: { show: true, textStyle: { fontSize: '30', fontWeight: 'bold' } } }, labelLine: { normal: { show: true, smooth: false, length: 35, // 第一條導視線長度 length2: 50, // 第二條導視線長度 lineStyle: { color: '#999', width: 0.5 } } }, itemStyle: { normal: { borderColor: '#fff', borderWidth: 7 } }, data: [ ] }
6.用transition作漸隱漸現,元素高度自適應時用height:auto 會有bug,改成max-height: xx ; xx 大於元素最大高度就能夠,width一樣適用jquery
css:git
.tip-icon:hover ~ .tip { opacity: 1; max-height: 400px; } .tip{ max-height: 0; opacity: 0; transition: all .5s .2s; }
html: 因爲個人tip 內容不少,因此用的是兄弟元素, 若是很少也能夠做爲tip-icon的子元素,只是css選擇器的區別github
<a href="#" class="tip-icon footprint"> <i class="fa fa-question-circle-o" aria-hidden="true"></i> </a> <div class="tip"> <!-- something --> </div>
