refer to the second floor and pure _ response:

 
The function echar (res) {
The console. The log (res [' cpuRealUsed ']);//note 
} 
The function the req () {
$. Ajax ({
Type: "GET", 
url: '../Bt. PHP ', 
DataType: 'json, 
Success: the function (res) {
Echar () 

}, 
Error: function () {
The console. The log (' attempt failed ~ '); 
} 
}); 
} 
The req (); 
SetInterval (the req, 1000);

Don't use the setInterval, if the response timeout, reconnection success leads to accept before stacking all requests for the result

Use var to define a null null object, due to the effect of variables with the ascending of the var definition, so the internal parameter directly, has become a global variables, the parameters can be in any place to visit or call
