有一个带有名为“Samenstelling”的字段集的订单。该字段集包含一个下拉选择，其中包含名为“多少”的数字。
如果选择数字 2，则该字段集中的所有其他字段必须出现两次，如果选择数字 3，则所有字段必须出现三次。
必须复制的字段集位于下面。 此外，如果字段完整并填写完毕，则必须将完整的表格邮寄到一个电子邮件地址。 有人可以帮我吗？

最佳答案
你可以这样做:
HTML
查看我对新添加的 div 的 fiddle
id="fieldcontwrapper"和 id="fieldcont"
jQuery
$(".cms_dropdown").live('change', function () {
var howmuch = $(this).val();
var data = $("#fieldcont").html(); // DATA TO DUPLICATE
// IF SELECTED <= 1, THEN REMOVE ALL DUPLICATES EXCEPT 1
if (howmuch <= 1) {
$("#fieldcontwrapper #fieldcont").not(':first').remove();
} else {
for (var i = 0; i < howmuch; i++) {
$("#fieldcontwrapper")
.append('<div id="fieldcont"> <hr />' + data + '</div>');
}
}
});
