JavaScript文件邏輯代碼：
var countTooGetLocation = 0;var total_micro_second = 0;var starRun = 0;var totalSecond = 0;var oriMeters = 0.0;/* 毫秒級(jí)倒計(jì)時(shí) */function count_down(that) { if (starRun == 0) { return; } if (countTooGetLocation >= 100) { var time = date_format(total_micro_second); that.updateTime(time); } if (countTooGetLocation >= 5000) { //1000為1s that.getLocation(); countTooGetLocation = 0; } setTimeout setTimeout(function(){ countTooGetLocation += 10; total_micro_second += 10; count_down(that); } ,10 )}// 時(shí)間格式化輸出，如03:25:19 86。每10ms都會(huì)調(diào)用一次function date_format(micro_second) { // 秒數(shù) var second = Math.floor(micro_second / 1000); // 小時(shí)位 var hr = Math.floor(second /
