sort array of numeric strings with Lodash

问题

_.sortBy(arrData, "rhid");

This code sorts array but as the values of field "rhid" are strings the order is messed up. How can i sort as if "rhid" where int field.

Thanks

回答1:

sortBy can be used with a function instead of a property name.

_.sortBy(arrData, function (obj) {
    return parseInt(obj.rhid, 10);
});
