为什么$ .post什么都不做？

Question

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js">
<script type="text/javascript">
  $(document).ready(function() {
    $.post("ajax.php", function(data) {
      alert("Data Loaded");
    });
  });
</script>

I understand that this code does nothing useful, but why does nothing happen? The php doesn't run, and the alert doesn't show.

Answer 1

Your first SCRIPT element is missing its closing tag </script>, which leads to the whole code being just ignored.
