Question

Ext.define('Olvldefnition', {
    extend: 'Ext.data.Model',
    fields: [
        {
                        name : 'defKey'
        },
        {
            name : 'defStructKey',
            type : 'int'
        },
        {
            name : 'defLevelNo',
            type : 'int'
        }, {
            name : 'defLevelDiscP',
            type : 'string'
        }, {
            name : 'defLevelDiscS',
            type : 'string'
        }, {
            name : 'defSeqNo',
            type : 'int'
        }
    ]
});


var storeDef = Ext.create('Ext.data.Store', {
    id: 'storeDef',
    model: 'Olvldefnition',
    proxy: {
       type: 'jsonp',
       api : {
    read : 'definition/view.action'
},
        reader: {
            type: 'json',
             root: 'data',
             idProperty: 'defKey',
             successProperty : 'success',
             messageProperty : 'message'
        }
 }
});

这是我的代码，它获取如下的JSON数据。

{
"total":3,
"data":[
{"modifiers":{"status":"A","effstartdate":"2012-04-02 00:00:00.0","effenddate":"2012-04-26 00:00:00.0","updateUser":"ARCSADMIN","updateDate":"2012-04-16 16:04:29.162","remarks":null,"entryDate":"2012-04-07 19:34:28.923","entryUser":"ARCSADMIN"},

但是它显示了像这样的错误

SCRIPT1004: Expected ';' 
view.action?_dc=1337079455042&page=1&start=0&limit=25&callback=Ext.data.JsonP.callback1, line 1 character 9

Answer 1

也许问题是代理type: 'jsonp'？

因为在您的示例中，我只看到json而非jsonp且您的api网址位于同一台服务器上，所以为什么不使用json代替jsonp？

示例：

var storeDef = Ext.create('Ext.data.Store', {
    id: 'storeDef',
    model: 'Olvldefnition',
    proxy: {
        type: 'ajax',
        api : {
            read : 'definition/view.action'
        },
        reader: {
            type: 'json',
            root: 'data',
            idProperty: 'defKey',
            successProperty : 'success',
            messageProperty : 'message'
        }
    }
});

Answer 2

我认为你在某处遇到了简单的语法错误。它与解析JSON数据无关。
