jquery - 如何使用 jquery 添加拖放 div？

问题描述

我想制作像看板模板这样的 html 页面。html 页面中有 Todo、Doing 和 Done 列列表。并且用户可以将 div 移动到此列表下的另一个列列表。但是我无法使用 jquery 拖放 div 组件。javascript代码或其他有问题吗？如果给出一个想法，我会非常高兴。先感谢您..

$(function() {
  var kanbanCol = $('.panel-body');
  kanbanCol.css('max-height', (window.innerHeight - 150) + 'px');
  var kanbanColCount = parseInt(kanbanCol.length);
  $('.container-fluid').css('min-width', (kanbanColCount * 350) + 'px');

  draggableInit();

  $('.panel-heading').click(function() {
    var $panelBody = $(this).parent().children('.panel-body');
    $panelBody.slideToggle();
  });
});

function draggableInit() {
  var sourceId;
  $('[draggable=true]').bind('dragstart', function(event) {
    sourceId = $(this).parent().attr('id');
    event.originalEvent.dataTransfer.setData("text/plain", event.target.getAttribute('id'));
  });

  $('.panel-body').bind('dragover', function(event) {
    event.preventDefault();
  });

  $('.panel-body').bind('drop', function(event) {
    var children = $(this).children();
    var targetId = children.attr('id');

    if (sourceId != targetId) {
      var elementId = event.originalEvent.dataTransfer.getData("text/plain");

      $('#processing-modal').modal('toggle'); //before post

      // Post data 
      setTimeout(function() {
        var element = document.getElementById(elementId);
        children.prepend(element);
        $('#processing-modal').modal('toggle'); // after post
      }, 1000);
    }

    event.preventDefault();
  });
