[SOLVED] datagrid & unexpected response from the server

[Coder]

how to intercept the answer from server before

API server periodically need to reauth and its answer something like the

{
"result":"error",
"error":"auth required"
}

and  datagrid do not event onLoadSuccess and do not event onLoadError
( in console: Uncaught TypeError: "Cannot read property 'length' of undefined" )

how to intercept this API server answer ?


UPD:

hmm ... in EasyUI 1.9.15 it turns out that neither 'onLoadSuccess' nor 'onLoadError' is ever called at all

Code:

 $('#DG').datagrid({
    ...
   ,onLoadError: function(){ console.log('DG load error'); }
   ,onLoadSuccess: function(aData){ console.log('DG load success',aData); }
   ...

currently possible only by overriding 'loader' ?

Please custom the 'loader' to achieve this functionality.

Code:

function loader(param, success, error){
	var opts = $(this).datagrid('options');
	if (!opts.url) return false;
	$.ajax({
		type: opts.method,
		url: opts.url,
		data: param,
		dataType: 'json',
		success: function(data){
			if (data.result == 'error'){
				error(data);
			} else {
				success(data);
			}
		},
		error: function(){
			error.apply(this, arguments);
		}
	});
}
