如何在引导中将值参数传递给modal.show()函数

I have a page the shows a list of local cafes. When the user clicks on a certain cafe, a modal dialog is shown, that already has the "cafe name" pre-filled. The page contains many cafe names, and the form should contain the "cafe name" that he clicked on.

我有一个页面显示了当地咖啡馆的列表。当用户单击某个咖啡馆时，将显示一个模态对话框，该对话框已经预先填充了“咖啡馆名称”。页面包含许多咖啡馆名称，表单应该包含他单击的“咖啡馆名称”。

Following is the list of cafe names generated as text with link button

下面是用link按钮以文本形式生成的cafe名称列表

         <table class="table table-condensed  table-striped">
      <tbody>   
        <tr>
          <td>B&Js
          </td>
          <td>10690 N De Anza Blvd </td>
          <td>
              <a class="btn btn-primary" data-toggle="modal" onClick="$('#createFormId').modal('show')" >Announce</a>
          </td>
        </tr>

        <tr>
          <td>CoHo Cafe
          </td>
          <td>459 Lagunita Dr </td>
          <td>
              <a class="btn btn-primary" data-toggle="modal" onClick="$('#createFormId').modal('show')" >Announce</a>
          </td>
        </tr>


        <tr>
          <td>Hot Spot Espresso and Cafe
          </td>
          <td>1631 N Capitol Ave </td>
          <td>
              <a class="btn btn-primary" data-toggle="modal" onClick="$('#createFormId').modal('show')" >Announce</a>
          </td>
        </tr>

      </tbody>
    </table>

Here is the modal form

这是模态形式

<div class="modal hide fade" id="createFormId"">
<div class="modal-header">
    <a href="#" class="close" data-dismiss="modal">&times;</a>
    <h3>Create Announcement</h3>
</div>
<div class="modal-body">
    <form class="form-horizontal" method="POST" commandName="announceBean" action="/announce" >
        <input type="hidden" name="cafeId" value="104" />
        <fieldset>
            <div class="control-group">
                <label class="control-label" for="cafeName">Where I am Coding</label>
                <div class="controls">
                    <input id="cafeName" name="cafeName" class="input-xlarge disabled" type="text" readonly="readonly" type="text" value="B&amp;Js"/>
                </div>
            </div>
            <div class="control-group">
                <label class="control-label" for="date">Date</label>
                <div class="controls">
                    <input type="text" class="input-xlarge" id="date" name="date" />
                    <p class="help-block"></p>
                </div>
            </div>
            <div class="control-group">
                <div class="controls">
                    <input type="submit" class="btn btn-primary" value="create" />
                    <input type="button" class="btn" value="Cancel" onclick="closeDialog ();" />
                </div>
            </div>
        </fieldset>
    </form>
</div>

Question is how to pass actual value into the "value" attribute of the modal form?

问题是如何将实际值传递到模态形式的“值”属性中?

<input type="hidden" name="cafeId" value="104" />

The form "show" event is triggered by "onlick" event

“show”事件由“onlick”事件触发

<a class="btn btn-primary" data-toggle="modal" onClick="$('#createFormId').modal('show')" >Announce</a>

3 个解决方案

#1

You could do it like this:

你可以这样做:

<a class="btn btn-primary announce" data-toggle="modal" data-id="107" >Announce</a>

Then use jQuery to bind the click and send the Announce data-id as the value in the modals #cafeId:

然后使用jQuery绑定单击并将公告数据id作为modals #cafeId的值发送:

$(document).ready(function(){
   $(".announce").click(function(){ // Click to only happen on announce links
     $("#cafeId").val($(this).data('id'));
     $('#createFormId').modal('show');
   });
});

#2

Use

使用

$(document).ready(function() {
    $('#createFormId').on('show.bs.modal', function(event) {
        $("#cafeId").val($(event.relatedTarget).data('id'));
    });
});

I want to share how I did this. I spent the last few days rattling my head with how to pass a couple of parameters to the bootstrap modal dialog. After much head bashing, I came up with a rather simple way of doing this.

我想分享我是如何做到这一点的。在过去的几天里，我绞尽脑汁地想着如何向引导模式对话框传递几个参数。在多次敲打头部之后，我想出了一个相当简单的方法。

Here is my modal code:

这是我的模态代码:

<div class="modal fade" id="editGroupNameModal" role="dialog">
  <div class="modal-dialog">
    <div class="modal-content">
      <div id="editGroupName" class="modal-header">Enter new name for group </div>
        <div class="modal-body">
          <%= form_tag( { action: 'update_group', port: portnum } ) do %>
          <%= text_field_tag( :gid, "", { type: "hidden" })  %>
          <div class="input-group input-group-md">
          <span class="input-group-addon" style="font-size: 16px; padding: 3;" >Name</span>
          <%= text_field_tag( :gname, "", { placeholder: "New name goes here", class: "form-control", aria: {describedby: "basic-addon1"}})  %>
        </div>
        <div class="modal-footer">
          <%= submit_tag("Submit") %>
        </div>
        <% end %>
      </div>
    </div>
  </div>
</div>

And here is the simple javascript to change the gid, and gname input values:

下面是用来更改gid和gname输入值的简单javascript:

function editGroupName(id, name) {
    $('input#gid').val(id);
    $('input#gname.form-control').val(name);
  }

I just used the onclick event in a link:

我只是在一个链接中使用了onclick事件:

//                                                                              ' is single quote
//                                                                                   ('1', 'admin')
<a data-toggle="modal" data-target="#editGroupNameModal" onclick="editGroupName(&#39;1&#39;, &#39;admin&#39;); return false;" href="#">edit</a>

The onclick fires first, changing the value property of the input boxes, so when the dialog pops up, values are in place for the form to submit.

onclick触发首先更改输入框的值属性，因此当对话框弹出时，表单的值将被提交。

I hope this helps someone someday. Cheers.
