Answer 1

纯 JavaScript 解决方案 Array#filter() :

function clean(array) {
    return array.filter(function (a) { return a.length; });
}

var a = [1, 2, 3, 4, 5],
    b = [2, 3, 5, 6, 1, 7],
    c = [1, 2, 43, 67, 8, 7],
    d = [],
    e = [],
    f = [],
    g = [5, 8, 9, 3],
    x = clean([a, b, c, d, e, f, g]);

document.write('<pre>' + JSON.stringify(x, 0, 4) + '</pre>');
