Launch the modal

Using modal dialogs is a common design pattern with core apps. This helper does most of the work for you, including AODA compliance.

The method below is a static method of the cot_app (if your app is standalone) or CotApp (if your app is embedded) class.

Use it like this:

CotApp.showModal(options); //embedded apps
cot_app.showModal(options); //standalone apps

footerButtonsHtml

Function
Let's the user define the footer for the modal

Example / Usage Details
If the value of footerButtonsHtml is defined
Here is where it falls in to the template of the Modal HTML:

Using options.footerButtonsHtml
'<div class="modal fade ' + options.className + '" id="' + id + '" tabindex="-1" role="dialog" aria-labelledby="' + id + '_title" aria-hidden="true" aria-modal="true">' + '    <div class="modal-dialog ' + options.modalSize + '">' + '      <div class="modal-content">' + '        <div class="modal-header">' + '          <button type="button" aria-label="Close" class="close" type="button" data-dismiss="modal">' + '            <span aria-hidden="true">×</span>' + '          </button>' + '          <div role="heading" aria-level="2" id="' + id + '_title" class="modal-title">' + options.title + '</div>' + '        </div>' + '        <div id="' + id + '_body" class="modal-body">' + options.body + '</div>' + '        <div class="modal-footer">' + options.footerButtonsHtml + '        </div>' + '      </div>' + '    </div>' + '  </div>';



Default behaviour for 'confirm' preset is to call the built in:
footerButtonsHtml: returnButton()
returnButton method

returnButton function
    var returnButton = function returnButton(bsType, opt) {
      if (opt && opt.hasOwnProperty('bootstrapType')) {
        var bsTypes = ['primary', 'success', 'info', 'warning', 'danger'];

        if (bsTypes.indexOf(opt.bootstrapType) == -1) {
          opt.bootstrapType = 'default';
        }
      }

There are two functions calls made when the 'confirm' preset is being used

confirm preset returnButton calls
returnButton('cancel', {
          bootstrapType: options.buttons.cancel.bootstrapType,
          label: options.buttons.cancel.label
        }) 
returnButton('confirm', {
          bootstrapType: options.buttons.confirm.bootstrapType,
          label: options.buttons.confirm.label
        });

Then the final footer is being built:

confirm preset final footer
<div class="modal-footer">' + returnButton('cancel', {
          bootstrapType: options.buttons.cancel.bootstrapType,
          label: options.buttons.cancel.label
        }) + ' ' + returnButton('confirm', {
          bootstrapType: options.buttons.confirm.bootstrapType,
          label: options.buttons.confirm.label
        });
        '        </div>'

To customize the footer you will want to do the last code section expect for the <div class="modal-footer"> </div> in your 
footerButtonsHtml
function
