如何用模态框替换 javascript 警报？

根据某些数据库结果，通过回显触发 javascript 警报

if response is a
{
     <script type="text/javascript">alert("response is a.");</script>
}
else
{
    <script type="text/javascript">alert("response is not a.");</script>
}

我正在使用引导程序，如果我们可以用引导程序模式替换警报，那就完美了

根据您可以在以下问题中找到的代码，冒昧地为您创建了一个 jsbin 示例：JavaScript: Overriding alert()

请注意，覆盖警报可能不是一个好主意，尤其是因为您将错过常规 javascript 警报的阻止属性。正如您在我的示例中所看到的，如果您快速连续使用 2 个警报，则最后一个警报将覆盖之前的警报。

只是补充@Kippie。

http://jsbin.com/sadesukuli/2/edit?html，输出

  <script type="text/javascript">
    (function() {
  var proxied = window.alert;
  window.alert = function() {
    modal = $('<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"><div class="modal-header"><button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button><h3 id="myModalLabel">Modal header</h3></div><div class="modal-body"><p>One fine body…&lt;/p></div><div class="modal-footer"><button class="btn" data-dismiss="modal" aria-hidden="true">Close</button></div></div>');
    modal.find(".modal-body").text(arguments[0]);
    modal.modal('show');
  };
})();


    alert('moo');
    alert('cow');
  </script>
</body>
</html>

“您的 jsbin 示例显示了对 alert('moo') 的调用，然后是 alert('cow')”

我的示例同时显示了“moo”和“cow”。
