JS与php的混合调用

[wuyuwww]

如何在js函数里面调用php的一些参数？

 

<script type="text/javascript">
function EnterPress(e)
{
   var e = e||window.event;
   if(e.keyCode==13)
   {
     if(this.disabled) return;
     var wrong = "Invalid Page Number";
    if(!isNum(document.form_search['data['.<?php echo $model; ?>.'[curpage]'].value))
    {  
      alert(wrong);
      return false;
    }
    else
    {
      document.form_search['data['.<?php echo $model;?>.[page]'].value=document.form_search['data['.<?php $model;?>.'][curpage]'].value;
      this.disabled = true;
      document.form_search.submit();
     }
  }
}
</script>
 $script = "JavaScript:  if (this.disabled) return;" .
                "var wrong = 'Invalid Page Number.';" .
                "if(!isNum(document.form_search['data[$model][curpage]'].value)){alert(wrong);return false;}" .
                "else{document.form_search['data[$model][page]'].value =" .
                "   document.form_search['data[$model][curpage]'].value;" .               
                "   this.disabled = true; document.form_search.submit();}";
echo '<input type="button" value="GO" onkeypress='EnterPress(event)' onkeydown="EnterPress()" onclick="'.$script."\"/>

我上面的那个EnterPress函数无法得到php里面的$model这个参数。
该怎么弄既得到JS的参数event又得到php里面的$model
