Website link where I tested regex
var string = "12.0,34.0";
var re = new RegExp("[-+]?([1-8]?\d(\.\d+)?|90(\.0+)?),\s*[-+]?(180(\.0+)?|((1[0-7]\d)|([1-9]?\d))(\.\d+))?");
if (re.test(string)) {
console.log("Valida");
} else {
console.log("Invalida");
}
Recalling what appears on my console is invalid! I have tested with other simple expressions and it works perfectly the code if someone knows the solution is that I know little or nothing about regex
Take the quotation marks. Try the following:
var string = "12.0,34.0";
var re = new RegExp(/[-+]?([1-8]?\d(\.\d+)?|90(\.0+)?),\s*[-+]?(180(\.0+)?|((1[0-7]\d)|([1-9]?\d))(\.\d+))?/);
if (re.test(string)) {
console.log("Valida");
} else {
console.log("Invalida");
}
I tested now, and gave as valid
Since the string you have is already formatted and you just need to know if it's valid or not, the best way is not RegExp but a numeric check. Given that the limits are:
Latitude (S-N): -90 to +90
Longitude (O-E): -180 to +180
You can do this:
function verificador(str) {
var coords = str.split(',').map(Number);
var validos = coords.filter(function(coord, i) {
return Math.abs(coord) <= 90 + (90 * i);
});
return validos.length == 2 ? coords : false;
};
console.log(verificador("30.02")); // false
console.log(verificador("30.02,-100.876")); // [30.02, -100.876]
console.log(verificador("330.02,-100.876")); // false
