加载comboBox后的Extjs 3.4加载网格

Question

Using Extjs 3.4. I have many JsonStore to load many ComboBox . I have an other JsonStore to load the data to populate an EditorGrid. I want to load the gridStore after all ComboBoxStores have finished the loading process. Is possible to do this?

Answer 1

Each store emits events such as beforeload , load , that could be used to hookup any additional logic after the store has loaded.

I am not sure about you specific use-case but what you could do is , fire a custom event from each of the JSONstores on load( "load" event) and keep track of number of combobox stores loaded. Once all stores are loaded you could load the gridStore.
