ExtJS grid callback on load and reload
提问by Manny Calavera
I have an Ext Grid and want to grab the JSON "success":false/true response an execute a function for each situation. I would like to have it as callback function for every grid interaction with the JSON PHP file.
我有一个 Ext Grid 并且想要获取 JSON "success":false/true 响应并为每种情况执行一个函数。我希望将它作为与 JSON PHP 文件的每个网格交互的回调函数。
Any examples of this ?
这有什么例子吗？
Thank you for your time.

You need to register callbacks to the loadand exceptionevents of the JsonStore. Something like this:
您需要注册对 JsonStore的加载和异常事件的回调。像这样的东西：
var grid = new Ext.grid.GridPanel({
store: new Ext.data.JsonStore({
[...]
listeners: {
load: this.onLoadSuccess.crateDelegate(this),
exception: this.onLoadException.createDelegate(this)
}
}),
onLoadSuccess: function () {
// success
},
onLoadException: function () {
// error
},
[...]
}
