在Bootstrap中使用.modal（“ toggle”）方法切换模式。
如下所示，模态通过单击按钮生成-
$(document).ready(function(){
$("#button1").click(function(){
$("#newModal").modal("toggle");
});
});这是上面使用的按钮-
<button type="button" class="btn btn-default btn-lg" id="button1"> Modal One </button>
您可以尝试运行以下代码以实现modal（“ toggle”）方法-
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">

$(document).ready(function(){
$("#button1").click(function(){
$("#newModal").modal("toggle");
});
});
