    function removeChildrenRecursively(node) {
    if (!node) return;
    while (node.hasChildNodes()) {

    JavaScript通过原型函数的封装对時間格式化函數:

    <script>
    Date.prototype.format = function(format)
    {
        var o = {
            "M+" : this.getMonth()+1, //month
            "d+" : this.getDate(),    //day
            "h+" : this.getHours(),   //hour
            "m+" : this.getMinutes(), //minute
            "s+" : this.getSeconds(), //second
            "q+" : Math.floor((this.getMonth()+3)/3), //quarter
