php返回表后移动一个值

Question

I have a title on my page. It is inside a div tag. When the page is displayed it is simple and says "Net Control Manager". After the user makes a selection a PHP program runs MySQL and returns a table. It also returns a value that I want to put into the title. So that it would say "Net Control Manager: PCARG" for example.

The problem is I'm not sure how to put that extra piece into the div. I write the value to another div with an echo from the php "echo $value" which is returned correctly. Then in an onload in the body tag I use a function to retrieve the new div (newport), and add it to the title div. But since the onload happens first all I get is "undefined".

How do I make it wait for the new div to be written with the new data? Or is there another method I don't know about.

If I read this correctly, you're just looking to pick up some text and append it to another div's text?

You could do something like this -- making sure it's at the bottom of your HTML before the closing </body> tag.

<script type="text/javascript">
  $(document).ready(function () {
    var title = $('#title'); // Or whatever your div id or class name is.
    var newport = $('#newport'); // Or whatever your div id or class name is.

    // This will append the text from your `newport` onto your `title` div. 
    title.text(title.text() + ' ' + newport.text())
  });
</script>
