在模态中重新加载内容（twitter bootstrap）

I'm using twitter bootstrap's modal popup.

我正在使用twitter bootstrap的模态弹出窗口。

<div id="myModal" class="modal hide fade in">
    <div class="modal-header">
        <a class="close" data-dismiss="modal">×</a>
        <h3>Header</h3>
    </div>
    <div class="modal-body"></div>
    <div class="modal-footer">
        <input type="submit" class="btn btn-success" value="Save"/>
    </div>
</div>

I can load content using ajax with this a-element:

我可以使用带有这个a元素的ajax加载内容：

<a data-toggle="modal" data-target="#myModal" href="edit.aspx">Open modal</a>

Now I have to open the same modal but using a different url. I'm using this modal to edit an entity from my database. So when I click edit on an entity I need to load the modal with an ID.

现在我必须打开相同的模态，但使用不同的URL。我正在使用此模式从我的数据库编辑实体。因此，当我在实体上单击编辑时，我需要加载带有ID的模态。

<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=1">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=2">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=3">Open modal</a>

If I click on link number 1, it works fine. But if I then click on link number 2 the modal content is already loaded and therefor it will show the content from link number 1.

如果我点击1号链接，它可以正常工作。但是，如果我点击链接号2，则已经加载了模态内容，因此它将显示链接号1的内容。

How can I refresh or reset the ajax loaded content in a twitter bootstrap modal popup?

如何在twitter bootstrap模式弹出窗口中刷新或重置ajax加载的内容？

I am having the same problem, and I guess the way of doing this will be to remove the data-toggle attribute and have a custom handler for the links.

我遇到了同样的问题，我想这样做的方法是删除data-toggle属性并为链接提供自定义处理程序。

Something in the lines of:

有点像：

$("a[data-target=#myModal]").click(function(ev) {
    ev.preventDefault();
    var target = $(this).attr("href");

    // load the url and show modal on success
    $("#myModal .modal-body").load(target, function() { 
         $("#myModal").modal("show"); 
    });
});

Will try it later and post comments.

稍后会尝试并发表评论。

To unload the data when the modal is closed you can use this with Bootstrap 2.x:

要在关闭模态时卸载数据，可以在Bootstrap 2.x中使用它：

$('#myModal').on('hidden', function() {
    $(this).removeData('modal');
});

And in Bootstrap 3 (https://github.com/twbs/bootstrap/pull/7935#issuecomment-18513516):

在Bootstrap 3中（https://github.com/twbs/bootstrap/pull/7935#issuecomment-18513516）：

$(document.body).on('hidden.bs.modal', function () {
    $('#myModal').removeData('bs.modal')
});

//Edit SL: more universal
$(document).on('hidden.bs.modal', function (e) {
    $(e.target).removeData('bs.modal');
});

#3

You can force Modal to refresh the popup by adding this line at the end of the hide method of the Modal plugin (If you are using bootstrap-transition.js v2.1.1, it should be at line 836)

您可以通过在Modal插件的hide方法的末尾添加此行来强制Modal刷新弹出窗口（如果您使用的是bootstrap-transition.js v2.1.1，则应该在第836行）

this.$element.removeData()

Or with an event listener

或者使用事件监听器

$('#modal').on('hidden', function() {
    $(this).data('modal').$element.removeData();
})

#4

With Bootstrap 3 you can use 'hidden.bs.modal' event handler to delete any modal-related data, forcing the popup to reload next time:

使用Bootstrap 3，您可以使用'hidden.bs.modal'事件处理程序删除任何与模态相关的数据，强制弹出窗口下次重新加载：

$('#modal').on('hidden.bs.modal', function() {
    $(this).removeData('bs.modal');
});

#5

Based on other answers (thanks everyone).

根据其他答案（感谢大家）。

I needed to adjust the code to work, as simply calling .html wiped the whole content out and the modal would not load with any content after i did it. So i simply looked for the content area of the modal and applied the resetting of the HTML there.

我需要调整代码才能工作，因为简单地调用.html擦除了整个内容，并且在我执行之后模式不会加载任何内容。所以我只是寻找模态的内容区域并在那里应用HTML的重置。

    $(document).on('hidden.bs.modal', function (e) {
        var target = $(e.target);
        target.removeData('bs.modal')
              .find(".modal-content").html('');
    });

Still may go with the accepted answer as i am getting some ugly jump just before the modal loads as the control is with Bootstrap.

仍然可以使用已接受的答案，因为我在模态加载之前得到一些丑陋的跳跃，因为控件是使用Bootstrap。

A little more compressed than the above accepted example. Grabs the target from the data-target of the current clicked anything with data-toggle=modal on. This makes it so you don't have to know what the id of the target modal is, just reuse the same one! less code = win! You could also modify this to load title, labels and buttons for your modal should you want to.

比上面接受的例子稍微压缩一点。使用data-toggle = modal on从当前单击任何内容的数据目标中抓取目标。这使得你不必知道目标模态的id是什么，只需重用同一个模块即可！少代码=胜利！你也可以修改它来为你的模态加载标题，标签和按钮。

 $("[data-toggle=modal]").click(function(ev) {
    ev.preventDefault();
    // load the url and show modal on success
    $( $(this).attr('data-target') + " .modal-body").load($(this).attr("href"), function() { 
         $($(this).attr('data-target')).modal("show"); 
    });
});

Example Links:

示例链接：

<a data-toggle="modal" href="/page/api?package=herp" data-target="#modal">click me</a>
<a data-toggle="modal" href="/page/api?package=derp" data-target="#modal">click me2</a>
<a data-toggle="modal" href="/page/api?package=merp" data-target="#modal">click me3</a>

#7

I made a small change to Softlion answer, so all my modals won't refresh on hide. The modals with data-refresh='true' attribute are only refreshed, others work as usual. Here is the modified version.

我对Softlion的回答做了一些小改动，所以我的所有模态都不会刷新。具有data-refresh ='true'属性的模态仅刷新，其他模块正常工作。这是修改后的版本。

$(document).on('hidden.bs.modal', function (e) {
    if ($(e.target).attr('data-refresh') == 'true') {
        // Remove modal data
        $(e.target).removeData('bs.modal');
        // Empty the HTML of modal
        $(e.target).html('');
    }
});

Now use the attribute as shown below,

现在使用如下所示的属性，

<div class="modal fade" data-refresh="true" id="#modal" tabindex="-1" role="dialog" aria-labelledby="#modal-label" aria-hidden="true"></div>

This will make sure only the modals with data-refresh='true' are refreshed. And i'm also resetting the modal html because the old values are shown until new ones get loaded, making html empty fixes that one.

这将确保只刷新data-refresh ='true'的模态。而且我也正在重置模态html，因为旧的值会被显示，直到新的值被加载，使得html空修复了一个。

It will works for all version of twitterbootstrap

它适用于所有版本的twitterbootstrap

Javascript code :

Javascript代码：

<script type="text/javascript">
/* <![CDATA[ */
(function(){
   var bsModal = null;
   $("[data-toggle=modal]").click(function(e) {
      e.preventDefault();
      var trgId = $(this).attr('data-target'); 
      if ( bsModal == null ) 
       bsModal = $(trgId).modal;
      $.fn.bsModal = bsModal;
      $(trgId + " .modal-body").load($(this).attr("href"));
      $(trgId).bsModal('show');
    });
 })();
/* <![CDATA[ */
</script>

links to modal are

与模态的链接是

<a data-toggle="modal" data-target="#myModal" href="edit1.aspx">Open modal 1</a>
<a data-toggle="modal" data-target="#myModal" href="edit2.aspx">Open modal 2</a>
<a data-toggle="modal" data-target="#myModal" href="edit3.aspx">Open modal 3</a>

pop up modal

弹出模态

<div id="myModal" class="modal hide fade in">
<div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
    <input type="submit" class="btn btn-success" value="Save"/>
</div>

Here is a coffeescript version that worked for me.

这是一个适合我的coffeescript版本。

$(document).on 'hidden.bs.modal', (e) ->
  target = $(e.target)
  target.removeData('bs.modal').find(".modal-content").html('')

#10

I was also stuck on this problem then I saw that the ids of the modal are the same. You need different ids of modals if you want multiple modals. I used dynamic id. Here is my code in haml:

我也坚持这个问题然后我看到模态的ID是相同的。如果你想要多个模态，你需要不同的模态id。我用动态id。这是我在haml中的代码：

.modal.hide.fade{"id"=> discount.id,"aria-hidden" => "true", "aria-labelledby" => "myModalLabel", :role => "dialog", :tabindex => "-1"}

you can do this

你可以这样做

<div id="<%= some.id %>" class="modal hide fade in">
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Header</h3>
  </div>
  <div class="modal-body"></div>
  <div class="modal-footer">
    <input type="submit" class="btn btn-success" value="Save" />
  </div>
</div>

and your links to modal will be

和你的模态链接将是

<a data-toggle="modal" data-target="#" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>

I hope this will work for you.

我希望这对你有用。

#11

I wanted the AJAX loaded content removed when the modal closed, so I adjusted the line suggested by others (coffeescript syntax):

我希望在模态关闭时删除AJAX加载的内容，所以我调整了其他人建议的行（coffeescript语法）：

$('#my-modal').on 'hidden.bs.modal', (event) ->
  $(this).removeData('bs.modal').children().remove()

#12

You can try this:

你可以试试这个：

$('#modal').on('hidden.bs.modal', function() { $(this).removeData('bs.modal'); });

$（'＃modal'）。on（'hidden.bs.modal'，function（）{$（this）.removeData（'bs.modal'）;}）;
