"仅当在下拉列表之外单击鼠标时才关闭引导下拉列表"

Question

I have a bootstrap dropdown menu:

<div class="dropdown>
   <a class="dropdown-toggle" href="#" id="menu1" data-toggle="dropdown"><img src="@imagePath" class="img-circle dropbtn" alt="Product" style="width:30px;height:30px;" /></a>

  <ul class="dropdown-menu" id="productDD" role="menu" aria-labelledby="menu1"></ul>
</div>

Now the ul load the products on page load through ajax call. The issue is when I click any product in the dropdown, the dropdown gets closed. But I want to close dropdown only when mouse is clicked anywhere outside of the ul

Answer 1

Try something like this:

$(document).click(function(e) {
  // get the clicked element
  $clicked = $(e.currentTarget);
  // if the clicked element is not a descendent of the dropdown
  if ($clicked.closest('.dropdown').length === 0) {
    // close the dropdown
    $('.dropdown').removeClass('open');
  }
});

Answer 2

just place this script in your code

<script>
    $(document).click(function() {
    $(".dropdown").removeClass('open');
});
</script>

In 2021 you do it this way:

$('.dropdown').on({
    "shown.bs.dropdown": function() { /* whatever you want to do when it fires */ },
    "click":             function(e) { // handles click event
      
       console.log(e.target) // just to check which element is on top

      if($('.dropdown-menu').is(e.target)) { // if dropdown is clicked
        this.closable = false // do not close it
        return;
      } else {
        this.closable=true; // else close it 
      }

    },
    "hide.bs.dropdown":  function() { return this.closable; } // save state
  });
}

Bootstrap 有一个内置的解决方案

<a class="dropdown-toggle" href="#" id="menu1" data-toggle="dropdown" data-bs-auto-close="outside"><img ... \/><\/a><\/code>
