我的json如下：
({
"status":"TRUE",
"message":"Words",
"data":[
{
"name":"paint",
"author":"snooky",
"word_id":"1",
"category":"Business",
"definitions":[
{
"rating":"Green",
"defintion":"to put color to in something",
"def_id":"1",
"example":null,
"author":"pit",
"is_favourite":"yesStar"
},
{
"rating":"Red",
"defintion":"this is a new definition of word paint.",
"def_id":"42",
"example":null,
"author":"bull",
"is_favourite":"noStar"
}
]
}
]
})
我正在解析这个值并在 tpl 中显示它，如下所示：
{
xtype: 'list',
store: 'words',
height: 140,
layout: 'fit',
scrollable: {
direction: 'vertical',
directionLock: true,
},
margin: '0 0 5px 0',
itemTpl: [
'<div>',
'<tpl for="data">',
'<ul class="parabox">',
'<li><h2><b>{name}</b></h2>',
'<tpl for="definitions">',
'<ul class="para-box-wrapper">',
'<li class="{rating}"><div >',
'<div class="paragraph-def" ><p id = "wordDefinition" >{defintion}</p></div>',
'<span class="authorBox"><i>Author: {author}</i></span>',
'<div id="favourite" class="{is_favourite}" ></div>',
'</div>',
'</li>',
'</ul>',
'</tpl>',
'</li>',
'</ul>',
'</tpl>',
'</div>',
].join(''),
listeners: {
itemtap : function(list, index, target, record, event) {
if (event.target.id=='wordDefinition') {
alert("Rating clicked!");
console.log(event.target.id);
console.dir("Definition--"+record);
//ratingStar();
}
if (event.target.id=='favourite') {
alert('Favourite clicked!');
console.log(event.target.id);
console.dir("Favourite--"+record);
//addToFavourite();
}
}
}
}
我的控制台如下：
![控制台][1]
如上图所示，当用户单击相应的 tpl 时，我想访问 def_id 和 word_id，如下图所示。做 record.data.data[0].definitions[0].def_id 我可以得到它，但我希望它是动态的，因为稍后可能会有 4-5 个定义。

我的店铺：
Ext.define('MyApp.store.wordsmenu',{
extend: 'Ext.data.Store',
config:
{
autoLoad:true,
model: 'MyApp.model.words',
id:'Contacts',
proxy:
{
type: 'ajax',
url: 'json',
reader:
{
rootProperty:''
}
}
}
});
我的模型是：
Ext.define('MyApp.model.words', {
extend: 'Ext.data.Model',
config: {
fields: [
{name: 'status', mapping: 'status'},
{name: 'message', mapping: 'message'},
{name:'data', mapping: 'data'},
{name: 'definitions', mapping: 'definitions.defintion'},
{name: 'ratings', mapping: 'definitions.rating'},
]
}
});
我能够在 tpl 中显示 json 值。现在，我应该跟踪单击特定定义和星号并将其 id 发送到服务器但无法获取 id。
