使用jQuery更新数据

Question

I have a page that lists records from a database call. I want to have an 'edit' link on each row that will popup a Jquery dialog so that the row can be edited. My question is how do I pass the data from the selected row to the jquery dialog box so that it can be edited? i have the code which open jquery popup but the textboxes are empty.

<div id="boxes">

<div id="dialog2" class="window">
<form method="post" action="update_books_a.php">
  <input name="name" type="text" value="<?php echo $ing['book_name']; ?>"/>

  <input name="author" type="text" value="<?php echo $ing['author']; ?>"/>

    <input type="hidden" name="book_id" value="<?php print $ing['book_id'];?>" />
    


<input type="submit" value="Update" class="close"/>
</form>
</div>

myphp code is

$select=mysql_query("select * from books where book_id='$book_id'") or die(mysql_error());
while($ing=mysql_fetch_array($select))
{
 ?>
<tr>
    <td><a href="#dialog2" name="modal"><?php echo $ing['book_name'];?></a></td>
    <td><?php echo $ing['author'];?></td></tr>

the jquery code is

$(document).ready(function() {

    //select all the a tag with name equal to modal
    $('a[name=modal]').click(function(e) {
        //Cancel the link behavior
        e.preventDefault();

        //Get the A tag
        var id = $(this).attr('href');

        //Get the screen height and width
        var maskHeight = $(document).height();
        var maskWidth = $(window).width();

        //Set heigth and width to mask to fill up the whole screen
        $('#mask').css({'width':maskWidth,'height':maskHeight});

        //transition effect
        $('#mask').fadeIn(1000);
        $('#mask').fadeTo("slow",0.8);

        //Get the window height and width
        var winH = $(window).height();
        var winW = $(window).width();

        //Set the popup window to center
        $(id).css('top',  winH/2-$(id).height()/2);
        $(id).css('left', winW/2-$(id).width()/2);

        //transition effect
        $(id).fadeIn(2000);

    });

    //if close button is clicked
    $('.window .close').click(function (e) {
        //Cancel the link behavior
        e.preventDefault();

        $('#mask').hide();
        $('.window').hide();
    });

    //if mask is clicked
    $('#mask').click(function () {
        $(this).hide();
        $('.window').hide();
    });

});

Answer 1

You can extract the text value of each element using the .text() method.
If you need the html value you can use .html() or yourNode.innerHTML

Answer 2

You don't have the book_id in the table, so I can't populate the hidden input for you. But the below code shows you how to do it for book_name and author, so hopefully that gives you enough to start with.

You need to add the code to your click handler, after this line:

//Cancel the link behavior
e.preventDefault();

Add this code:

// Copy book_name
$("#dialog2 input[name=name]").val($(this).text());

// Copy author
$("#dialog2 input[name=author]").val($(this).parent().next("td").text());
