sorry for fail pasting the js code, I wonder whether there is a version gap with jquery and server.

var client;  
$(document).ready(function () {   
client = new $.es.Client({  
hosts: [  
{  
host: "app.biglog.cn",  
auth: "defender:AU0XvPWYFZihVQi1YYcA"  
}  
]  
//auth: 'defender:AU0XvPWYFZihVQi1YYcA',  
//auth: "huliant:biglog.org"  
});  
});

function query\_data(){  
client.cluster.health(function (err, resp) {  
if (err) {  
alert(err.message);  
} else {  
alert(resp);  
}  
});  
}
