后台返回的经纬度数据往往例如是：119.569280这样的数据，我们前端可能要转为115°0'33.41"N，38°0'59.26"E这样的数据或者是115,0,33.41，38,0,59.26这样的数据
//度转度°分′秒″
function ToDegrees(val) {
if (typeof (val) == "undefined" || val == "") {
return "";
}
var i = val.indexOf('.');
var strDu = i < 0 ? val : val.substring(0, i);//获取度
var strFen = 0;
var strMiao = 0;
if (i > 0) {
var strFen = "0" + val.substring(i);
strFen = strFen * 60 + "";
i = strFen.indexOf('.');
if (i > 0) {
strMiao = "0" + strFen.substring(i);
strFen = strFen.substring(0, i);//获取分
strMiao = strMiao * 60 + "";
i = strMiao.indexOf('.');
strMiao = strMiao.substring(0, i + 4);//取到小数点后面三位
strMiao = parseFloat(strMiao).toFixed(2);//精确小数点后面两位
}
}
return strDu + "," + strFen + "," + strMiao; // 这里可以修改成你想要的格式例如你可以
// 改成这样的：return strDu + "°" + strFen + "'" + strMiao + "\"N";
}
//度°分′秒″转度
function ToDigital(strDu, strFen, strMiao, len) {
len = (len > 6 || typeof (len) == "undefined") ? 6 : len;//精确到小数点后最多六位
strDu = (typeof (strDu) == "undefined" || strDu == "") ? 0 : parseFloat(strDu);
strFen = (typeof (strFen) == "undefined" || strFen == "") ? 0 : parseFloat(strFen) / 60;
strMiao = (typeof (strMiao) == "undefined" || strMiao == "") ? 0 : parseFloat(strMiao) / 3600;
var digital = strDu + strFen + strMiao;
if (digital == 0) {
return "";
} else {
return digital.toFixed(len);
}
}
