regex-仅将输入和输出替换为小数?[复制品]

var latlong = 'ID: 39.825 -86.88333';

var point = latlong.match( /-?\d+\.\d+/g );

//result: point = ['39.825', '-86.88333'];

匹配一个值

-?\d+\.\d+

对于这两个值:

(-?\d+\.\d+)\ (-?\d+\.\d+)

如果字符串始终具有以下形式:

"ID: 39.825 -86.88333".match(/^ID:\ (-?\d+\.\d+)\ (-?\d+\.\d+)$/)

function parseLatLong(str) {
    var exp = /ID:\s([-+]?\d+\.\d+)\s+([-+]?\d+\.\d+)/;

    return { lat: str.replace(exp, "$1"), long: str.replace(exp, "$2") };          
}

function doSomething() {
    var res = parseLatLong("ID: 39.825 -86.88333");

    alert('Latitude is ' + res.lat + ", Longitude is " + res.long);
}
