用JS為一段HTML元素設定隨機顏色字型

• HTML中的元素

<p id='broadcast'>testtest</p>

• JS部分

var chars = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'];

function generateMixed(n) {
    var res = "";
    for (var i = 0; i < n; i++) {
        var id = Math.ceil(Math.random() *
 
 16);
        res += chars[id];
    }
    return res;
}

var num = generateMixed(6);
var p = document.getElementById('broadcast');
p.style.color = "#" + num;
