        // callback on change 
    })

Set values with

observedVar(value)

Get values with

var value = observedVar()

HttpRequest

HttpRequest.get("test-request.txt", function (response) {

    console.log(response)
}, function (errorMessage) {
    // failure
    console.error(errorMessage)
})

Utils

Examples

// Cookies

// Call this first, to provide the webtools as global objects
// if you don`t call this, you have to access the objects via 
// the prefix `wt` (i.e. wt.Cookie.set(name,value)). 
wt.setGlobals()

// write a cookie
Cookie.set("testcookie", "123")
// read a cookie
console.log("Cookie", Cookie.get("testcookie"))

// Observed variable

// observe the value of the variable `observedVar`
var observedVar = new Observed(function (newValue, oldValue) {
    console.log("newValue", newValue)
    console.log("oldValue", oldValue)
})
// write the value of the variable `observedVar`
observedVar("New Value")
// read the value of the variable `observedVar`
console.log("observedVar()", observedVar())

// HttpRequest

HttpRequest.get("test-request.txt", function (response) {
    // success
    console.log(response)
}, function (errorMessage) {
    // failure
    console.error(errorMessage)
