javascript - 添加/删除小部件以及调整大小不起作用

Question

我使用了基本的 gridster 代码，然后我声明了通过按钮添加和删除小部件的函数它工作正常但是当我将调整大小功能添加到上面的代码中时，它都不起作用(我的意思是调整大小，添加和删除小部件)

我的js代码如下

<script type="text/javascript">
    var gridster;

    gridster = $(".gridster ul").gridster({
        widget_base_dimensions: [100, 100],
        widget_margins: [5, 5],
        helper: 'clone',
        resize: {
            enabled: true
        }           


    }).data('gridster');



$(document).on( "click",".delete-button", function() {
var gridster = $(".gridster ul").gridster().data('gridster');
gridster.remove_widget($(this).parent());
});



$(document).on( "click",".add-button", function() {
var gridster = $(".gridster ul").gridster().data('gridster');      
gridster.add_widget('<li><button class="delete-button" style="float: 
right;">-</button><h3></h3></li>',1,1);
});

以上代码不起作用

工作代码中没有这个

resize: {
        enabled: true
    }

引用解决方案here ，已使用 ressized()

更新了您的代码

还添加了 css 文件 jquery.gridster.css。

$(function() {
  var gridster;
  var grid_size = 100;
  var grid_margin = 5;
  gridster = $(".gridster ul").gridster({
    widget_base_dimensions: [100, 100],
    widget_margins: [5, 5],
    helper: 'clone',
    resize: {
      enabled: true
    }


  }).data('gridster');



  $(document).on("click", ".delete-button", function() {
    var gridster = $(".gridster ul").gridster().data('gridster');
    gridster.remove_widget($(this).parent());

  });



  $(document).on("click", ".add-button", function() {
    gridster
      .add_widget('<li><button class="delete-button" style="float: right;">-</button><h3></h3></li>', 1, 1);
    gridster.resizable({
      grid: [grid_size + (grid_margin * 2), grid_size + (grid_margin * 2)],
      animate: false,
      minWidth: grid_size,
      minHeight: grid_size,
      containment: '#layouts_grid ul',
      autoHide: true,
      stop: function(event, ui) {
        var resized = $(this);
        setTimeout(function() {
          resizeBlock(resized);
        }, 300);
      }
    });
  });
})

<h1>Add and Remove Widget Dynamically</h1>

<p>When you remove a widget,the widget below it will always remain in the same column.Widget from next column wont come in place of widget removed.Gridster is designed that way</p>
