s 假设我有一个视图, 可以生成模型. fetch (), 然后请求服务器 。
I would like to implement:
1) A checker able to memorise the result
2) refresh the result (making the request to the server) only if the last request to the server is older than ten minutes.
What should I do?
Is there already a piece of code to make that?
define([], function() {
var MyModel = Backbone.Model.extend({
url: function () {
return "http://localhost/restapi/model/";
},
fetch () {
if(diffTime > 10minutes) {
// make request to the server
}
else {
// return memo
}
}
});
});
