A complete json should be contained by the brace bar (eg {data: [{name: 'aa', age: 3}, {name: 'aa', age: 3} ...... ..]})
you this. . It can only be called an array. . Have to have a name, such as arrayA = [{name: 'aa', age: 3}, {name: 'aa', age: 3} ...]
then call it is the arrayA [0]. name ....

"CategoryId": 1,

"IconCls": "category-item-button-icon-network" 
},

"CategoryId": 2, 
 
"CategoryName": "play the game", 
 
"IconCls": "category-item-button-icon-game" 
}

First, take out things that are strings. Because you outside with the [] enclosed, which is two elements, each element is enclosed in curly braces. When you put this element as a javaBean, then categoryId, categoryName, iconCls is its attributes. The value of the time, if you want to take the "play game", this value, it is necessary so write: data [1]. CategoryName. And so on, are so written on the line. . .
