script.src = xyUrl; //借鉴了jQuery的script跨域方法 script.onload =
script.onreadystatechange = function(){ if((!this.readyState ||
this.readyState === "loaded" || this.readyState === "complete")){
callback && callback(); // Handle memory leak in IE
script.onload = script.onreadystatechange = null; if ( head
&& script.parentNode ) { head.removeChild( script );
} } }; // Use insertBefore instead of appendChild to
circumvent an IE6 bug. head.insertBefore( script, head.firstChild ); }
function transMore(points,type,callback){ for(var index in points){
if(index > 50){return;} var xyUrl =
"http://api.map.baidu.com/ag/coord/convert?from=" + type +
"&to=4&x=" + points[index].lng +
//这里要循环读入数组points的lng数据，直到points.length完毕。 "&y=" + points[index].lat
+ "&callback=callback"; //动态创建script标签
loadscript(xyUrl); } }

window.BMap = window.BMap || {}; BMap.Convertor = {};
BMap.Convertor.transMore = transMore; })(); ```
