document.ready被多次调用

<?php
    $this->render("header.php");
?>

my about us page

<?php
  $this->render("footer.php");
?>

这只是执行include()的一种花哨方式。然而,header.php有一些javascript可以通过jquery框架在document.ready上运行,需要header的页面也是如此。所以你有这样的东西

<?php
    $this->render("header.php"); // has its own $(document).ready
?>
<script type="text/javascript">
     $(document).ready(function(){
          console.log("test");
     });
 </script>

测试

<script type="text/javascript">
     $(document).ready(function(){
          // do some javascript like highlighting 
          // form elements with specific classes
     });
</script>
  display header here 

<script type="text/javascript">
     $(document).ready(function(){
          console.log("test");
     });
 </script>
