如官网上所说，data-toggle="dropdown"不能省略
data-toggle="dropdown" still required
Regardless of whether you call your dropdown via JavaScript or instead use the data-api, data-toggle="dropdown" is always required to be present on the dropdown's trigger element.

<script>
$(function(){
$(".dropdown-toggle").one("click",function(){
$(this).dropdown("toggle");
})
})
