Default style

<link rel="stylesheet" href="YOU/PATH/dist/css/custom-alert.css">

Default bootstrap style

<link rel="stylesheet" href="YOU/PATH/dist/css/custom-alert-bootstrap.css"> 

and script

<!--<script src="YOU/PATH/dist/js/custom-alert.min.js">-->

There are two ways to apply customAlert.

The first is to start the function by allowing it to automatically override the alert() and confirm() global (window.alert, window.confirm).

    new customAlert();
    confirm("Confirm text", function(done){
        alert('Alert text')
    })

The second returning the functions in an object, so it passes false as an attribute of customAlert()

    var custom = new customAlert(false);
    custom.confirm("Confirm text", function(done){
        custom.alert('Alert text')
    })

Simply.

    alert("Alert text")

Editing title and button text;

    alert("Alert text", {title: 'Olá', button: "Go!"})

Performing a callback after the operation.

    alert("Alert text", {title: 'Olá', button: "Go!"}, function(){
        //...
    })

Calling a callback to handle the result. In this case, the callback receives an argument with true or false

    confirm("Alert text", function(done){
        if(done){
            alert('true')
        }
        else{
            alert('false')
        }
    })

Defining different callbacks for different results.

    confirm("Comfirm text", {
        "success" : function(){
            //..
        },
        "cancel" : function(){
            //..
        }
    })

Setting Title and Text of Buttons.

    confirm("Comfirm text", function(done){
        //..
    }, { 
        "title" : "Wellcome",
        "done": {
                "text": ":)",
        },
        "cancel": {
            "text" : ":(",
            "default": true
        }
    })

• title: The title.
• done: The button text.

• title.text The title.
• title.default If true, set the default as default.
• title.bold Add bold text.
• done.text The done text.
• done.default If true, set the default as default.
• done.bold Add bold text.
• cancel: The cancel text.

• success: if button done press.
• cancel: if button calcel press.
• only function: Gets an attribute with true or false.

The ENTER key performs the default button.

{
    "cancel": {
        "default" : true
    }
}

In this example, the default button will be "Cancel", so by clicking ENTER on the keyboard, this button will be executed. By default the "default button" is done.
