Question

我需要将javascript变量存储在下表中：

Nodeid  parentid   theme            Document

4787814 4787484 Theme1       Document 1
4787824 4787484 Theme2       NULL
4787834 4787824 Theme2.1     Document 1 of theme 2.1
4787834 4787824 Theme2.1     Document 2 of theme 2.1 
4787834 4787824 Theme2.1     Document 3 of theme 2.1
4787844 4787824 Theme2.2     Document 1 of theme 2.2
4787854 4787824 Theme2.2     Document 2 of theme 2.2

是否有任何jquery或javascript代码可以帮助我将此表存储在类似的结构中。目前我有以下javascript代码。

var ThemesCollection=
    {
        Themes: {},
        Initialize: function() 
        {
          ThemesCollection.Themes=new Object();
        }
    }

Answer 1

您可以使用对象

function ThemesCollection(Nodeid, parentid, theme, Document) {
  this.Nodeid = Nodeid;
  this.parentid = parentid;
  this.theme = theme;
  this.Document = Document;
}

然后使用ThemesCollection个对象的数组（如果你用ajax检索它）

function on_success(data) {
   for (row in data) {
     globalThemes.push(new ThemesCollection(row[0], row[1], row[2], row[3]);
     // or i row is object
     //new ThemesCollection(row['Nodeid'], row['parentid'], row['theme'], row['Document'])
   }
}

Answer 2

矩阵（数组数组）怎么样？

[ [ 4787814, 4787484, "Theme1",       "Document 1" ],
  [ 4787824, 4787484, "Theme2",       null ],
  [ 4787834, 4787824, "Theme2.1",     "Document 1 of theme 2.1" ],
  [ 4787834, 4787824, "Theme2.1",     "Document 2 of theme 2.1" ],
  [ 4787834, 4787824, "Theme2.1",     "Document 3 of theme 2.1" ],
  [ 4787844, 4787824, "Theme2.2",     "Document 1 of theme 2.2" ],
  [ 4787854, 4787824, "Theme2.2",     "Document 2 of theme 2.2" ] ]

如果x是您的矩阵，您只需添加新项目：

x.push（[4787859,4787824，“Theme X”，“Document foobar”]）

Answer 3

使用JavaScript Object Notation。

var info = [
{
"Nodeid" : 4787814,
"parented" : 4787484,
"theme" : "Theme1",
"Document" : "Document 1"
},
{
"Nodeid" : 4787824,
"parented" : 4787484,
"theme" : "Theme2",
"Document" : "NULL"
}]

然后，您可以像这样使用二维数组;

alert(info[0].theme)

javascript中的二维数组
