à l'aide de simplemodal, spectacle de chargement spinner, tandis que les contenus à l'intérieur de l'iframe charges

Je suis en utilisant un peu plus longue version de spin.js pour de belles toupies et modal spinner superpositions. Il peut être utilisé sur n'importe quel élément, simplement:

$('#ELEMENT_ID').spin()

ou modale, les filateurs:

$('#ELEMENT_ID').spin("modal")

appel tourner de nouveau pour l'éteindre et retirer la casserole de nouveau. C'est à quoi il ressemble:

C'est le spin.min.js y compris une extension jQuery et quelques défaut opte pour modale toupies:

J'ai été en mesure de résoudre ce problème en insérant un chargement div à l'intérieur de la simplemodal source, puis en appelant afficher/masquer au besoin de mon code.
