Answer 1

<div class="input-group input-append date" id="fromdatePicker1"></div>
<div class="input-group input-append date" id="fromdatePicker2"></div>

的jQuery

// get the last DIV which ID starts with ^= "fromdatePicker"
var $div = $('div[id^="fromdatePicker"]:last');

// Read the Number from that DIV's ID (i.e: 2 from "fromdatePicker2")
// And increment that number by 1
var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;

// Clone it and assign the new ID (i.e: from num 3 to ID "klon3")
var $fromdatePicker = $div.clone().prop('id', 'fromdatePicker'+num );

// >>> Append $fromdatePicker wherever you want

调用日期范围选择器

$('div[id="fromdatePicker^"]').daterangepicker();

或使用class

$('.common-class-name').daterangepicker();
