'loader' attribute problem in panel

[officecode]

I encountered two problems when using the panel's loader property:

1)  If the url in ajax is wrong, how do I use the function 'error' and give an error message? I tried to solve it in the onLoadError event, but it didn't work.

2)  When using the loader, I must also set a url that is not empty, otherwise Ajax will not make a request.

These two questions are puzzling and ask for help. Thank you！
Here is the sample code:

Code:

$('#test').panel({
	title: 'mytitle',
	width: 300,
	height: 100,
	href:' ',     //The href attribute cannot be empty, otherwise the loader is invalid.
	queryParams:{
		v1:'abc'
	},
	loader:function(para,success,error){
		$.get('test1.php',para,function(data){
			success(data)
			//If the request is wrong, how can I call the error function and give a prompt message?
		})
	}
})

1. When the loading is error, the 'onLoadError' event fires.

Code:

$('#p').panel({
	href: '_content1.html',
	onLoad: function(){
		alert('load ok')
	},
	onLoadError: function(){
		alert('load error')
	}
})

2. The is the default 'loader' definition, you can override it by yourself.

Code:

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

Tested with this code, no matter what the href changes to, the 'onLoadError' event will not fire.

It seems that this should be my local server problem. Thank you!
