javascript - Twitter Bootstrap 2 模式表单对话框

Question

我有以下对话框:

<div class='modal' id='myModal'>
  <div class='modal-header'>
    <a class='close' data-dismiss='modal'>×</a>
    <h3>Add Tags</h3>
  </div>

  <div class='modal-body'>
    <form accept-charset="UTF-8" action="/tagging" data-remote="true" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="mCNvbvoPFWhD7SoJm9FPDh+BcRvCG3d16P+oOFACPuc=" /></div>
        <input id="tags_string" name="tags_string" type="text" value="luca" />
        <input id="id" name="id" type="hidden" value="4f1c95fd1d41c80ff200067f" />
    </form>
  </div>

  <div class='modal-footer'>
    <div class='btn btn-primary'><input name="commit" type="submit" value="Add tag" /></div>
  </div>
</div>

和他的 JS :

<script>
  //<![CDATA[
    $(function() {
      // wire up the buttons to dismiss the modal when shown
      $("#myModal").bind("show", function() {
        $("#myModal a.btn").click(function(e) {
          // do something based on which button was clicked
          // we just log the contents of the link element for demo purposes
          console.log("button pressed: "+$(this).html());
          // hide the dialog box
          $("#myModal").modal('hide');
        });
      });
      // remove the event listeners when the dialog is hidden
      $("#myModal").bind("hide", function() {
          // remove event listeners on the buttons
          $("#myModal a.btn").unbind();
      });
      // finally, wire up the actual modal functionality and show the dialog
      $("#myModal").modal({
        "backdrop" : "static",
        "keyboard" : true,
        "show" : true // this parameter ensures the modal is shown immediately
      });
    });
  //]]>
</script>

当我点击 x 时，即 <a class='close' data-dismiss='modal'>×</a> ，表单关闭，让我留在当前页面，而我想进入主页。

还有“添加标签”按钮，即 <div class='btn btn-primary'><input name="commit" type="submit" value="Add tag" /></div>不要什么都不做，点击键盘上的 jaust ENTER 即可完成这项工作，我想点击“添加标签”也能做同样的事情。

我对 JS 和前端编程不太熟练，所以欢迎任何帮助。

您的提交按钮位于表单标签之外。
它不知道要提交什么表单。

使用 javascript 将其连接到表单。

<div class='modal-body'>
    <form id="modal-form" accept-charset="UTF-8" action="/tagging" data-remote="true" method="post">
        <input name="something" value="Some value" />
    </form>
  </div>

<div class='modal-footer'>
    <a id="modal-form-submit" class='btn btn-primary' href="#">Submit</a>
</div>

<script>
  $('#modal-form-submit').on('click', function(e){
    // We don't want this to act as a link so cancel the link action
    e.preventDefault();

    // Find form and submit it
    $('#modal-form').submit();
  });
</script>

至于<a class='close' data-dismiss='modal'>×</a>应该链接到主页，为什么不直接删除 data-dismiss='modal'并使用标准 href='home.html' 使其像普通链接一样工作。

下面是一些附加代码，可以为您指明使用 AJAX 提交表单的正确方向:

// Since we want both pressing 'Enter' and clicking the button to work
// We'll subscribe to the submit event, which is triggered by both

$('#modal-form').on('submit', function(){

  //Serialize the form and post it to the server
  $.post("/yourReceivingPage", $(this).serialize(), function(){

    // When this executes, we know the form was submitted

    // To give some time for the animation, 
    // let's add a delay of 200 ms before the redirect
    var delay = 200;
    setTimeout(function(){
      window.location.href = 'successUrl.html';
    }, delay);

    // Hide the modal
    $("#my-modal").modal('hide');

  });

  // Stop the normal form submission
  return false;
});
