从JavaScript调用PHP会阻止grid.js工作

I'm trying to call a PHP page from JavaScript but don't want to use a div tag to display the results as it seems to interfere with grid.js which I am using. Does anybody know of a way which is easy to do. I'm not passing any valuables between the pages.

Many thanks

<script>
$(document).ready(function(){
    $.ajax({url: "webserver", success: function(result){
      $("#div1").html(result);
    }});
});
</script>


<div id="div1"></div>
