保存以前的AJAX响应

Question

I'm doing AJAX-requests within an Intervalfunction in Javascript (e.g. once every 10 seconds).

I want to store the response (text ~ of the previous request) in a Javascript variable.

When the next request takes place, I want to check if the new response matches the previous one or not.

Something like:

var temp_data = response; //store response here
var final_data;

if(){
 final_data = temp_data;
} 
else {

}

Need soms advice/help,

Thanks!

Solved by storing responses in an array and slicing existing and pushing new object.

if (ajaxResults.length < 2) { //As long as arraylength < 2
   ajaxResults.push(data); //Add object (executed for 2 objects)
} else if (ajaxResults.length == 2) { //
   ajaxResults.splice(0, 1); //Remove 1 object at index 0, next element that was in array goes to index 0
   ajaxResults.push(data); //Add last response to the end of array with push() = at index 1
}
