在网格中不要忘记添加这个 columns: [],
然后在 store 下 listeners: { 'metachange': function(store, meta) { myGrid.reconfigure(商店,元.列);} }
和响应 json 文件应该有包含字段和列的元数据.阅读文档中的响应元数据部分以了解更多信息.
I have a json file and I assume that I do not know anyting about the content. I do not know the model. However it is given in the json file the model, the data, and other information about the grid. How I'll create the columns etc in this way?
http://docs.sencha.com/ext-js/4-1/#!/api/Ext.data.reader.Json -> Response MetaData section
in the grid don't forget to add this one columns: [],
then under the store listeners: { 'metachange': function(store, meta) { myGrid.reconfigure(store, meta.columns); } }
and the response json file should have metaData with fields and columns. Read Response MetaData section in the documentation for more info.
