在Bootstrap模式中滚动到​​DIV

Question

我有3个按钮，将触发相同的模式，但需要滚动到不同的部分。 我正在努力实现这一目标，请提供帮助。

<a data-toggle="modal" data-target="#myModal" class="btn-goto-section-1"> Launch modal </a>
<a data-toggle="modal" data-target="#myModal" class="btn-goto-section-2"> Launch modal </a>
<a data-toggle="modal" data-target="#myModal" class="btn-goto-section-3"> Launch modal </a>

<!-- Modal -->
<div class="modal fade" id="myModal">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-body">
        <div id="section-1">
          ...
          ...
          ...
          ...
          ...
        </div>
        <div id="section-2">
          ...
          ...
          ...
          ...
          ...
        </div>
        <div id="section-3">
          ...
          ...
          ...
          ...
          ...
        </div>
      </div>
    </div>
  </div>
</div>

使用显示的模态事件shown.bs.modal并使用该部分的data 。 可以在event.relatedTarget上找到打开模式的链接。

干得好：-

 $('#myModal').on('shown.bs.modal', function(event) { // reset the scroll to top $('#myModal .modal-body').scrollTop(0); // get the section using data var section = $(event.relatedTarget).data('section'); // get the top of the section var sectionOffset = $('#' + section).offset(); //scroll the container $('#myModal .modal-body').animate({ scrollTop: sectionOffset.top - 30 }, "slow"); }); 

 .red, .green, .blue { height: 300px; } .red { background-color: red; } .green { background-color: green; } .blue { background-color: blue; } .modal-body { max-height: 350px; overflow: auto; } }

就像@Virendra yadav注释一样，如果模态具有动态高度，并且您要滚动主体，而不是模态内的div，则替换为：-

// get the top of the section
var sectionOffset = $('#' + section).offset();
//scroll the container
$('#myModal .modal-body').animate({
   scrollTop: sectionOffset.top - 30
}, "slow");

与

// get the div position
var position = $('#' + section).position();
// scroll modal to position top
$("#myModal").scrollTop(position.top);

这是一个主意。 一旦显示了模式滚动（如shown.bs.modal ）。

$(document).ready(function(){
    $('#myModal').on('shown.bs.modal', function (event) { 
      $target = $('#section-3');
      $('.modal-body').animate({
        scrollTop: $target.offset().top + 'px'
      }, 'fast');

    });
});
