Modern Material Design Dialog Generator In Pure JavaScript – duDialog

duDialog is a pure JavaScript plugin for creating Material Design inspired alert, confirmation, selection dialog popups without any dependencies.

How to use it:

To get started, insert the duDialog’s JavaScript and CSS files into the page.

<link href="duDialog.css" rel="stylesheet">
<script src="duDialog.js"></script>

Create a basic alert dialog with an OK button.

new duDialog('Alert Message', 'This is an alert message.');

Create a confirmation dialog with callbacks.

new duDialog('Confirm Dialog', 'Are You SUre', duDialog.OK_CANCEL, { 
    okText: 'Confirm',
    callbacks: {
      okClick: function(){
        // do something
      },
      cancelClick: function(){
        // do something
      }
    }
});

new duDialog('Select An Item', ['CSS', 'SCRIPT', 'COM'], {
  selection: true, 
  callbacks: {
    itemSelect: function(e, item){
      // this.value
    }
  }
});
// or
new duDialog('Select An Item', 
    [{ name: 'CSS', id: 1 }, { name: 'SCRIPT', id: 2 }, { name: 'COM', id: 3 }], 
    {
    selection: true,
    textField: 'name',
    valueField: 'id',
    callbacks: {
      itemSelect: function(e, i){
        // this.value
      }
    }
});

callbacks: {
  /**

   * @param {Event} e - event object
   */
  okClick(e);
  /**
   * Triggers on CANCEL button click; 'this' inside the callback refers to the dialog object
   * @param {Event} e - event object
   */
  cancelClick(e);
  /**
   * Triggers on item selection change (selection dialog); 'this' inside the callback refers to the radio button.
   * For multiple selection dialog, this will be triggered on OK button click (okClick will not be executed); 'this' does not refer to the checkbox
   * @param {Event} e - event object;

   * @param {string|Object} i - select item object or string

  /**

  minRequired(min);
  /**
