改Calendar函数最后倒数第2句div的样式

JScript code

// create an element with the new id and insert the calendar //==============这里把div默认隐藏================document.write(' <div id="' + ContainerId + '" style="display:none"> ' + this.HTML + ' </div> '); } // Returns Id of the element containing the calendar return ContainerId; }
