Cannot use $(this) in $.getJSON in .each - this

Question

Im building a custom Minecraft Server Status and hit a problem. The first version of this was successful but the code was rather long and I decided to make it better and shorter. The script is supposed to fill the elements of each .server but it doesn't work.
<div class="server_status">
<div class="container servers_info">
<h1>My Network</h1>
<div id="of the server" class="server" title="of the server" server-ip="0.0.0.0">
<div class="name"></div>
<div class="count"><i class="fa fa-spinner fa-spin"></i></div>
<div class="players">Loading player data <i class="fa fa-spinner fa-spin"></i></div>
<div class="status"></div>
</div>
<div id="of the server" class="server" title="of the server" server-ip="0.0.0.0">
<div class="name"></div>
<div class="count"><i class="fa fa-spinner fa-spin"></i></div>
<div class="players">Loading player data <i class="fa fa-spinner fa-spin"></i></div>
<div class="status"></div>
</div>
<!-- ..... more servers -->
<span class="total"><i class="fa fa-spinner fa-spin"></i></span>
</div>
$(document).ready(function ping() {
$( ".servers_info .server" ).each( function() {
var name = $(this).attr( "title" );
var ip = $(this).attr( "server-ip" );
var id = $(this).attr( "id" );
var total = 0;
var call = "Get Avatar List adress";
//Set the name:
$(".name",this).html(name);
//Gets the data:
$.getJSON("http://mcapi.ca/v2/query/info/?ip=" + ip, function (json) {
//Checks The status and applies visual effects:
if (json.status !== "false") {
$(".status",this).html("<span class=\"l-online\">" + json.ping + " ms</span>");
$(this).removeClass('blur');
} else {
$(".status",this).html("<span class=\"l-offline\">0 ms</span>");
$(this).addClass('blur');
};
});
});
//Sets Refresh rate of 10s
setTimeout(ping, 10000);
});
I narrowed down the problem to the $.getJSON part. The data is retrieved correctly but cannot be placed in its respective DIVs. The only difference with the first version of the script is that I used 4 getJSON separately for each of the servers I wanted to display. Now using .each to combine it for all 4 of them and also $(this) to use relative objects.
I suspect the problem is in th usage of $(this) in .get but I'm nnot sure and don't know how to fix it.

As you suspect, the issue is the $(this). part. Inside the $.getJSON callback this no longer refers to the DOM object that triggered the event.
To fix this you can either:
Add a .bind(this) to the callback function. No changes required inside the function itself.
$.getJSON(url, function(json) {
/* all your code here */
}.bind(this)
);
Or save the reference to this before $.getJSON and use it inside the callback.
var _this = this;
$.getJSON(url, function(json) {
/* replace all references of this to _this for example*/
$(_this).removeClass('blur');
});
Hope that helps
