ExtJS stores

Description

目的是不要每次都加载 json文件，从而加快运行速度。

Code

You could configure your stores with a memory proxy:

store: {
    model: 'Forum.model.Post',
    proxy:{
        type: 'memory'
        reader: {
            type: 'json'
            root: 'posts'
        }
    }
}

Then fetch the data once with an Ext.Ajax.request and load it into each store using the proxy:

Ext.Ajax.request({
    url: '../api/json.php',
    success: function(response) {
        var result = Ext.JSON.decode(response.responseText);

        store.getProxy().data = result;
        store.load();
        // same procedure for the other stores...
    }
});

Reference

• ExtJS stores - load JSON only once
