调用 例：
两个按钮
window.dialog({
title : "弹出框标题",
showCloseButton : true,
content : '<div>弹出框内容</div>',
btnClassName : "t-center",
buttons: {
"确定按钮": function() {
//点击确定按钮执行的方法
},
"取消": function() {
//点击取消按钮执行的方法 默认为关闭弹出框
}
}
});
一个按钮
window.dialog({
title : "弹出框标题",
showCloseButton : true,
content : '<div>弹出框内容</div>',
btnClassName : "t-center",
buttons: {
"按钮提示": function() {
}
}
});
