Question

I have a simple function that does nothing:

function doNothing(){}

I also have a function that looks like this:

function getJson() {
    var JSONObject = {
        "name": "John Johnson",
        "street": "Oslo West 555",
        "age": 33,
        "phone": "5551234var stuff = <%= @var %>;567"
    };
    document.getElementById("name").value = JSONObject.name;
    setTimeout(doNothing(), 1000);
    document.getElementById("street").value = JSONObject.street;

So the doNothing() function is actually here only so I can put a parameter in the setTimeout function.

The point of the whole javascript code is that i want the first value to be shown immediatly and the second one after 1 second (1000miliseconds), but it never shows up.

Can someone please tell me what am I doing wrong?

The settimeout is not a sleep function, it will take a function and call it after 1000 milliseconds. Your other code will still execute right away.

Try:

document.getElementById("name").value = JSONObject.name;

setTimeout(function(){
    document.getElementById("street").value = JSONObject.street;
}, 1000);
