I fixed this by hooking into the modal hidden/shown events.
My amended script looks like this:

<pre><code> var login = function () {

 var handleRegister = function () {

 $("a, button").click(function (e) {
 var target = $(this).data("target");
 var type = $(this).data("type");

 if (target &amp;&amp; type) {
 var visible = $(target).is(":visible");

 if (!visible) { 
 var available_height = $(window).height() - $('.topbar').outerHeight();
 var content = $('.modal-content', target);
 content.height(available_height);

 $('.modal').each(function () {
 $(this).modal('hide'); // hide all existing modals
 });

 $(target).modal('show');
 }

 e.preventDefault();
 }
 });

 $('.modal').on('hidden.bs.modal', function (e) {
 $("body").removeClass("modal-open");
 });

 $('.modal').on('shown.bs.modal', function (e) {
 $("body").addClass("modal-open");
 });
 }

 return {
 init: function () {
 handleRegister();
 }
 }
 }();
</code></pre>

I am unsure why this works as I would expect that this is what would be happening in the modal script anyway. But it works, so hey ho.

blocks|key|998175|text|这是我的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|998176|998177|在你打开第二个模态之前：|998178|​|998179|hasAlreadyModalOpen+=+$("BODY").hasClass("modal-open");
mySecondModal.modal("show");

});|code-block|syntax|javascript|998180|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|O|8|@]|9|@]|A|$]]|$1|C|3|D|5|6|7|P|8|@]|9|@]|A|$]]|$1|E|3|F|5|6|7|Q|8|@]|9|@]|A|$]]|$1|G|3|H|5|I|7|R|8|@]|9|@]|A|$J|K]]|$1|L|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|M|$]]

Here is my solution:
<hr>
Before you open your second modal:

<pre><code>hasAlreadyModalOpen = $("BODY").hasClass("modal-open");
mySecondModal.modal("show");

mySecondModal.on('hidden.bs.modal', function (e) {
 if (hasAlreadyModalOpen) {
 $("body").addClass("modal-open");
 }
});
</code></pre>

blocks|key|998190|text|一个很老的问题，但一个简单的答案，因为这是高搜索结果，这仍然是一个问题。向任何辅助模式(如sub-modal+)添加一个额外的类，然后链接到它们的隐藏事件，只会减轻这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|998191|$(document).on("hidden.bs.modal",".sub-modal.modal",+function+()+{

A very old question but a simplified answer as this is high on search results and it is still an issue.
Adding an additional class to any secondary modals e.g. <code>sub-modal</code> and then hooking into their hidden event will mitigate this simply.

<pre><code>$(document).on("hidden.bs.modal",".sub-modal.modal", function () {
 $("body").addClass("modal-open");
});
</code></pre>

I have this issue where I need to open multiple modals. The good thing is that before I open a new modal, the existing one can be closed.
When a modal is opened normally I get a class applied to the body called "modal-open" which applies overflow: hidden to the body.

I created this script:

<pre><code>var login = function () {

 var handleRegister = function () {

 $("a").click(function (e) {
 var target = $(this).data("target");

 if (target) {
 var visible = $(target).is(":visible");

 if (!visible) { 
 $('.modal').each(function () {
 $(this).modal('hide'); // hide existing modals
 });

 $(target).modal('show');
 }

 e.preventDefault();
 }
 });
 }

 return {
 init: function () {
 handleRegister();
 }
 }
}();
</code></pre>

As you can see, I loop through any existing modals and close them (I assume this calls the hidden.bs.modal and removes the modal-open class from the body) and after these have run I call the show method on my target.
The problem is the modal-open class is not applied to the body.

I tried adding $("body").addClass("modal-open") after the show call, but the class is not added. 

Has someone come across this before?

我有一个问题，我需要打开多个调制解调器。好的是，在我打开一个新的模式之前，现有的模式可以关闭。通常情况下，当一个模态被打开时，我会得到一个应用于主体的类，称为“modal open”，它将溢出:隐藏的应用于主体。我创建了这个脚本：var login = function () {    var handleRegist...
