Filter problem

[springimport]

I have an error with a filter function.

Uncaught TypeError: Cannot read property 'filter' of undefined
    at HTMLInputElement.change ((index):412)
    at HTMLInputElement.u [as __onchange] (d3.v3.min.js:1)

function change() {
    // Filter out any zero values to see if there is anything left
    var remove_zero_values = dataset[this.value].filter(function(value) {
        return value > 0;
    });
...

My solution:

if (dataset[this.value] !== undefined) {
    var remove_zero_values = dataset[this.value].filter(function(value) {
        return value > 0;
    });
} else {
    var remove_zero_values = [];
}
