如何通過單擊超鏈接打開引導程序模版中的文本框來設置其值?

[英]How to set value to a text-box present on bootstrap modal after it opened up by clicking on a hyperlink?

我在網站上使用Bootstrap v3.3.5

單擊后,我有一個超鏈接,該超鏈接會打開一個引導模式對話框。 該超鏈接的HTML如下:

<a href="#myModal-add-event" data-toggle="modal">Add Event</a>

模態對話框的HTML代碼如下:

<div id="myModal-add-event" class="modal fade" role="dialog">
  <div role="document" class="modal-dialog add-event">
    <div class="modal-content">
      <div class="modal-body">
        <h4 class="modal-title event-title">Add an Event</h4>
        <form method="post" action="{$site_url}add_event.php" id="formAddEvent" >
          <!-- The gmail look alike loader should display here only upon successfull submission of a form. -->
          <div class="form-group" id="addEventErrorMsg" style="display:none; color:#FF0000;">
          </div>
          <div class="form-group">
            <input type="text" name="txt_event_title" id="txt_event_title"  autocomplete="off" class="form-control custom-height" placeholder="Event Title" style="height:30px;" />
           </div>
           <div class="form-group">
             <textarea type="text" name="txt_event_description" id="txt_event_description"  autocomplete="off" class="form-control custom-height" placeholder="Description (optional)" style="height:60px;" ></textarea>
           </div>
           <table border="0" cellspacing="10">
             <tr>
               <th><span class="event-title1" style="margin-bottom:5px;">Start Date:</span></th>
               <th><span class="event-title1" style="margin-bottom:5px;">End Date:</span></th>
             </tr>
             <tr>
               <td>
                 <div style="margin-right:15px;" class="form-inline form-group event-selection">
                 <div class="form-group has-feedback">

                     <span aria-hidden="true" class="glyphicon glyphicon-calendar form-control-feedback"></span>
                   </div>
                 </div>
               </div>
             </td>
             <td>
               <div class="form-inline form-group event-selection">
                 <div class="form-group has-feedback">

                     <span aria-hidden="true" class="glyphicon glyphicon-calendar form-control-feedback"></span>
                   </div>
                 </div>
               </div>
             </td>
           </tr>
         </table>   
         <div class="form-group has-feedback">
           <input type="text" name="txt_event_location" id="txt_event_location"  autocomplete="off" class="controls form-control custom-height" placeholder="Event Location" style="height:30px;" />

         <div class="modal-footer text-center">
           <button class="btn btn-primary" id="btn_add_event" type="button">Add Event</button>
           <button data-dismiss="modal" class="btn btn-default" type="button">Cancel</button>
         </div>
       </form>
     </div>
   </div>
 </div>
</div>

我想將值設置為Hello ...您好嗎? 進入ID為'selected_groupname'的文本框

為此,我嘗試使用下面的代碼,但對我而言不起作用。

$(document).ready(function() {
  $(function() {
    $('#myModal-add-event').bind('show',function(){
      $("#selected_groupname").val('Hello...How are you?');
    });
  });
});

另外,我檢查了Firebug控制台。 我也沒有收到任何錯誤或警告。

請有人幫我。

我認為您沒有將功能綁定到模態的正確事件。

Bootstrap模態具有一些用於show.bs.modal, shown.bs.modal, hide.bs.modal, hidden.bs.modal, loaded.bs.modal模態功能的自定義事件: show.bs.modal, shown.bs.modal, hide.bs.modal, hidden.bs.modal, loaded.bs.modal

您應該使用的事件是show.bs.modal ,當調用show實例方法時,它將立即觸發。

嘗試以下代碼:

$(document).ready(function() {
    $('#myModal-add-event').on('show.bs.modal',function(){
        $("#selected_groupname").val('Hello...How are you?');
    });
});

您可以在此處閱讀有關引導模式事件的更多信息: http : //getbootstrap.com/javascript/#modals-events

引導模態捕獲的事件是這樣的:

$('#modalselector').bind('show.bs.modal'....

不知道它是拼寫錯誤還是您是否在js代碼中缺少selected_groupname的#

$("#selected_groupname").val('Hello...How are you?');

嘗試這個:

$("a").click(function(){
   $("#selected_groupname").val(" Hello...How are you? ");
});
