如果要将内容设置为Bootstrap模态，请使用.modal(options)方法。
单击按钮后，将生成模态，如以下脚本所示。
$(document).ready(function(){
$("#button1").click(function(){
$("#newModal1").modal({backdrop: true});
});
});上面，我将选项设置为“ background：true”。我们可以设置的另一个选项是“背景：true”-
| 背景：true =在模态之外单击，将其关闭。 背景：false =在模态之外单击不会关闭它。 |
您可以尝试运行以下代码来实现modal（“ options”）类-
