Im working on color quiz game. I would like to get random color + this color name from JSON.

My JSON example:

{ "color":"#72362a", "name":"green", "namePL":["zielony"]}, }, { "color":"#7a3543", "name":"yellow", "namePL":["żółty"]}, } ];

How I can set body background to random from JSON and get name of used color?

Found random color code but I want to get color from JSON.

RandomColor = function() { colors = ['red', 'white', 'blue', 'green'] return colors[Math.floor(Math.random()*colors.length)]; }

What should I modify to get what I want?

I want to change color of background and get name of this color:

$('#colorname').text(name);

• jquery
• json

Try something like this:

var myJson = [{ "color":"#72362a", "name":"green", "namePL":["zielony"]}, { "color":"#7a3543", "name":"yellow", "namePL":["żółty"]}, ] ; var getColour; $(function(){ getColour = function(){ var entry = myJson[Math.floor(Math.random()*myJson.length)]; return entry; } $("#getColour").click(function(){ var localObj = getColour(); $("#divTest").html("Color name: " + localObj.name); $("#divTest").css('background-color', localObj.name ); }); });

In your random color function, you could replace the Array ['red', 'white'..] with your JSON Array. Now the RandomColor object will be a JSON object and you can access the color and name values as you would any JSON object.

RandomColor = function() { colors = [{"color":"#72362a","name":"green","namePL":["zielony"]},{"color":"#7a3543", "name":"yellow", "namePL":["żółty"]}]; return colors[Math.floor(Math.random()*colors.length)]; }

Now you can use RandomColor.color and RandomColor.name to get the values you need.
