Question

我是javascript和jquery的新手所以请耐心等待。我需要使用以下结构创建数组的动态哈希

{
    "cricket_fields": ["aniket", "shivam" ],
    "soccer_fields": ["tiwari", "sandeep", "abhijeet" ]
    "football_fields": ["varun", "shikhar","naveen","sudheer","apaar"],

}

我的代码问题是每当

  var fields = {};
$.each( $(BUILDER.selected_field_items), function(key,value  ){
       fields[$(this).data('group')] =  [$(this).data('label')]  

    }); 

$(BUILDER.selected_field_items) =
[div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, div.field_items, prevObject: n.fn.init(1), context: document, selector: "#selected_fields_container div.field_items"]

当迭代这个对象时，我找到了（$（this）.data（＆＃39; group＆＃39;））和带有$（this）.data（＆＃39; label＆＃39; ）

div.field_items =

    "<div class="field_items" data-label="aniket" data-index="0" data-group="cricket_fields">Aniket    <span class="plus-icon action-icon">+</span>    <i class="icon-cross2 action-icon"></i>  </div>"

我已经显示了特定div.fields_items

的数据

Answer 1

我不知道$(BUILDER.selected_field_items)是什么，但这应该达到你想要的目的：

if (key in fields) {
  // push `value` into the array if the key is found
  fields[key].push(value)
} else {
  // create an array with the first index set to `value` and set it to fields[key]
  fields[key] = [value]
}
