How to set cache false for getJSON in jQuery?

Your code just needs a trigger for it to be enabled.

This will allow you to disable cache in all future ajax

$(document).ready(function() {  $.ajaxSetup({ cache: false });});

Hope it helps :)

You can use either this, that will disable cache globally:

$(document).ready(function() {  $.ajaxSetup({ cache: false });});

or that, instead of $.getJSON, to disable the cache just for such request:

$.ajax({    cache: false,    url: "/path/to.json",    dataType: "json",    success: function(data) {        ...    }});

semente's and bonesnatch's answers are correct, but if you want to use $.getJSON and elsewhere take advantage of it's caching (you don't want to set the cache to false for all calls), but you want to bust the cache just for a single call, you can inject a timestamp into data property of $.getJSON(). By adding a unique value to the query string of the request, the request will always be unique and not be cached by the browser - you will always get the latest data.

Long version:

var ts = new Date().getTime();var data = {_: ts};var url = '/some/path.json';$.getJSON(url, data);

All in one version:

$.getJSON('/some/path', {_: new Date().getTime()});

Both result in the following request:

/some/path.json?_=1439315011130 

where the number at the end is the timestamp for the moment that the code is called and will therefore always be unique.
