回答1:

$( document ).ready( function() {
    $( '#myModal' ).modal( 'toggle' );
});

Is that what you're looking for ?

回答2:

try:

<script type="text/javascript">
  $(document).ready(function() {
    $('#teste').modal({
      show: true,
    })
  });
</script>

Example:

 <!-- css -->
 <link href="css/bootstrap.css" rel="stylesheet" type="text/css" >
 <script src="js/jquery.js"></script>
 <script src="js/bootstrap.js"></script>

 <script type="text/javascript">
 $(document).ready(function() {
   $('#myModal').modal({
    show: true,
   })
 });
</script>

 <!-- Button trigger modal -->
 <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
   Launch demo modal
 </button>

 <!-- Modal -->
 <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-     labelledby="myModalLabel" aria-hidden="true">
   <div class="modal-dialog">
     <div class="modal-content">
       <div class="modal-header">
         <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
         <h4 class="modal-title" id="myModalLabel">Modal title</h4>
       </div>
       <div class="modal-body">
         ...
       </div>
       <div class="modal-footer">
         <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
         <button type="button" class="btn btn-primary">Save changes</button>
       </div>
     </div><!-- /.modal-content -->
   </div><!-- /.modal-dialog -->
 </div><!-- /.modal -->

Your code will actually work. The thing you are doing wrong is the placement of the javascript portion.

You simply need to put the javascript portion of your code at the bottom of your document just before the closing body tag.

I just tested your code, as is, with a long document and it fails. All I did was move your javascript to the bottom of the page and it works perfectly.

There is another stack overflow that talks about why this is a best practice in some cases (JavaScript on the bottom of the page?).

Best to you!
