Question

添加XML链接，但我想使用JS变量：

var dependencyStore = Ext.create("Gnt.data.DependencyStore", {
        autoLoad: true,
        proxy: {
            type : 'ajax',
            url: 'dependencies.xml',
            method: 'GET',
            reader: {
                type : 'xml',
                root : 'Links',
                record: 'Link' // records will have a 'Link' tag
            }
        }
    });

dependancies.xml

<Links>
    <Link>
        <From>3</From>
        <To>4</To>
        <Type>2</Type>
    </Link>
</Links>

现在这是新代码，带有新的依赖存储和JS变量：

我的依赖商店实例目前看起来像这样：

var dependencyStore = Ext.create("Gnt.data.DependencyStore", {
            autoLoad    : true,
            proxy       : {
            type    : 'memory',
            reader  : {
                type: 'json'
            },

            data: [ assign ]
        }           
});

我的assign变量看起来像这样

var assign = [{
    "From" : 3,
    "To" : 4,
    "Type" : 2
}
]

问题在于，就是没有创建链接。

编辑：整个文件

Ext.ns('App');

//Ext.Loader.setConfig({enabled: true, disableCaching : true });
//Ext.Loader.setPath('Sch', '../../../ExtScheduler2.x/js/Sch');

            }
        });
    }
};

当我有

时

data: [ assign ]

在我的js文件中，我的 assign 变量中没有[ ]个标签。

所以而不是

var assign = [{
"From" : 3,
"To" : 4,
"Type" : 2

} ]

使用

var assign = {
"From" : 3,
"To" : 4,
"Type" : 2 }
