如何在jquery或javascript和PHP中将GPS度转换为十进制,反之亦然?

有人知道如何将GPS度转换为十进制值,反之亦然?

我必须开发一种方法,用户可以插入地址并获取GPS值(程度和/或小数),但我需要知道的主要是如何转换值,因为用户还可以插入GPS值(度或小数)。 因为我需要从谷歌地图获取地图,这需要小数。

我尝试了一些代码,但我得到了大数字…就像这个:

function ConvertDMSToDD(days, minutes, seconds, direction) { var dd = days + minutes/60 + seconds/(60*60); //alert(dd); if (direction == "S" || direction == "W") { dd = '-' + dd; } // Don't do anything for N or E return dd; } 

任何人?

谢谢。

首先感谢@Eugen Rieck的帮助。 这是我的最终代码,希望它可以帮助某人:

小数到十进制

 function getDMS2DD(days, minutes, seconds, direction) { direction.toUpperCase(); var dd = days + minutes/60 + seconds/(60*60); //alert(dd); if (direction == "S" || direction == "W") { dd = dd*-1; } // Don't do anything for N or E return dd; } 

十进制到基于此链接的度数

 function getDD2DMS(dms, type){ var sign = 1, Abs=0; var days, minutes, secounds, direction; if(dms < 0) { sign = -1; } Abs = Math.abs( Math.round(dms * 1000000.)); //Math.round is used to eliminate the small error caused by rounding in the computer: //eg 0.2 is not the same as 0.20000000000284 //Error checks if(type == "lat" && Abs > (90 * 1000000)){ //alert(" Degrees Latitude must be in the range of -90. to 90. "); return false; } else if(type == "lon" && Abs > (180 * 1000000)){ //alert(" Degrees Longitude must be in the range of -180 to 180. "); return false; } days = Math.floor(Abs / 1000000); minutes = Math.floor(((Abs/1000000) - days) * 60); secounds = ( Math.floor((( ((Abs/1000000) - days) * 60) - minutes) * 100000) *60/100000 ).toFixed(); days = days * sign; if(type == 'lat') direction = days<0 ? 'S' : 'N'; if(type == 'lon') direction = days<0 ? 'W' : 'E'; //else return value return (days * sign) + 'º ' + minutes + "' " + secounds + "'' " + direction; } alert(getDD2DMS(-8.68388888888889, 'lon'));
