因為公司項目的需要，需要開發一套室內地圖，并實現路線的規劃功能。因為之前沒做過這方面的開發，相關的資料也比較少，所以只能一個人去摸索。剛開始我是使用一般的位圖去當作的地圖，但是這個也讓我在后面吃了不少的苦頭。
我們知道地圖一般都會有縮放和拖拽等功能，正當我把一樣利用位圖開發的地圖樣例時，我發現了不少的問題：
1、位圖縮放會失真；
2、圖片加載比較慢；
3、會導致客戶端內存溢出
。。。
因為這些問題，我不得不放棄這種方法。要解決上面的問題只能使用矢量圖進行開發了，于是我使用了Html5進行了矢量圖的開發，不僅解決了地圖縮放失真等問題，還同時適用于Android、ios等，個人感覺效果還是相當的好，下面我來介紹一下此種方法：

一、矢量地圖

因為是矢量地圖，那肯定得要有矢量圖的數據，那么可能就得去了解一下SVG，在這里我就不進行介紹了，大家想學習的可以到網上搜索到很多相關的介紹，下面是地圖規定的一種格式：

/*** Created by Administrator on 2015/11/5.*/ $.fn.vectorMap('addMap', 'us_aea_en',{"insets":[{"width": 220, "top": 440, "height": 146.9158157558812, "bbox": [{"y": -8441281.712315228, "x": -5263934.893342895}, {"y": -6227992.545028123, "x": -1949631.2950683108}], "left": 0},{"width": 80, "top": 460, "height": 129.05725678001465, "bbox": [{"y": -4207380.690946597, "x": -5958501.652314129}, {"y": -3658201.4570359783, "x": -5618076.48127754}], "left": 245},{"width": 900.0, "top": 0, "height": 550.2150229714246, "bbox": [{"y": -5490839.2352678, "x": -2029243.6460439637}, {"y": -2690044.485299302, "x": 2552083.9617675776}], "left": 0}],"paths": {"BH-中國建設銀行":{"path":"M567.065,977.503h56.717v120.192h-56.717V977.503z" , "name":"中國建設銀行"},"BH-煌上煌":{"path":"M726.819,646.031h103.775v49.061H726.819V646.031z" , "name":"煌上煌"},"BH-佰匯服務中心":{"path":"M746.113,458.64v46.49v3.559v46.49h80.856v-46.49v-3.559v-46.49H746.113z" , "name":"佰匯服務中心"},"BH-01":{"path":"M746.113,365.117h84.245v96.714h-84.245V365.117z" , "name":"none"},"BH-九疑米粉":{"path":"M598.614,599.228v46.803v2.258v46.802h131.719v-46.802v-2.258v-46.803H598.614z" , "name":"九疑米粉"},"BH-02":{"path":"M598.614,552.426h131.719v49.061H598.614V552.426z" , "name":"none"},"BH-中國福利彩票":{"path":"M598.614,505.624h79.599v49.061h-79.599V505.624z" , "name":"中國福利彩票"},"BH-03":{"path":"M598.614,459.134h79.599v49.061h-79.599V459.134z" , "name":"none"},"BH-04":{"path":"M598.614,402.612h79.599v59.22h-79.599V402.612z" , "name":"none"},"BH-黑龍茶":{"path":"M621.338,977.503h56.716v120.192h-56.716V977.503z" , "name":"黑龍茶"},"BH-蒸美味":{"path":"M675.61,841.39h72.875v256.305H675.61V841.39z" , "name":"蒸美味"},"BH-集信飲食":{"path":"M828.102,921.006h60.87v176.689h-60.87V921.006z" , "name":"集信飲食"},"BH-衣生衣世":{"path":"M828.102,841.39h60.87v81.99h-60.87V841.39z" , "name":"衣生衣世"},"BH-佰匯公寓酒店":{"path":"M886.33,549.978h61.136v142.816H886.33V549.978z" , "name":"佰匯公寓酒店"},"BH-水果美容體":{"path":"M889.937,505.13h74.252v47.925h-74.252V505.13z" , "name":"水果美容體"},"BH-纖藝美甲":{"path":"M889.937,460.764h74.252v47.924h-74.252V460.764z" , "name":"纖藝美甲"},},"height":1200.333,//地圖的高"projection":{"type": "aea","centralMeridian": -100.0}, "width": 2384.0//地圖寬});

二、設置地圖的縮放量

zoomMin:0.5, zoomMax:8,

三、設置地圖背景顏色

backgroundColor:'#FFF',

四、設置店鋪文字的隨地圖縮放

onViewportChange: function(e, scale, transX, transY){console.log('viewportChange', scale, transX, transY);var old = parseInt($("text").css("fontSize"));console.log("字體大小：" + old);if( scale < 2.5 || scale == 2.5 ){$("text").hide();}else if(scale > 2.5 && scale < 3.5 || scale == 3.5){$("text").css("fontSize", 9);$("text").show();}else if(scale > 3.5 && scale < 4.5 || scale == 4.5){$("text").css("fontSize", 10);$("text").show();}else if(scale > 4.5 && scale < 5.5 || scale == 5.5){$("text").css("fontSize", 14);$("text").show();}else{$("text").css("fontSize", 16);$("text").show();}},

五、點擊商鋪觸發的方法

onMarkerOver: function(event, index){console.log('marker-over', index);},onMarkerOut: function(event, index){console.log('marker-out', index);},onMarkerClick: function(event, index){console.log('marker-click', index);},onMarkerSelected: function(event, index, isSelected, selectedMarkers){console.log('marker-select', index, isSelected, selectedMarkers);if (window.localStorage) {window.localStorage.setItem('jvectormap-selected-markers-BH-1',JSON.stringify(selectedMarkers));}},

六、效果圖
