Ajax不能正常工作吗？

function submitForm()
{
    $.ajax({
        type: 'GET', 
        url: 'iccrefresh.php', 
        data: $('this').serialize(),
        dataType:'script',
        error: function()
                { $( "#dialog_error" ).dialog( "open" ); },
        success: function()
                { $( "#dialog_success" ).dialog( "open" ); }
            });
    return false;
}

在 Php 中：

echo "<form name='refresh' onsubmit='return submitForm();'>";
echo "<input type='hidden' name='team1' value=$teamx />";
echo "<input type='hidden' name='team2' value=$teamy />";
echo "<input type='submit' name='submit' align='middle' value='Refresh Match Score'/>";
echo "</form>";

为什么我不能派第一队和第二队过去，有什么原因吗？我得到了一条成功的信息，但为什么 ccrefresh 无法访问团队1和团队2的值？

Try this:

echo "<form name='refresh' onsubmit='return submitForm();'>";
echo "<input type='hidden' name='team1' value='".$teamx."' />";
echo "<input type='hidden' name='team2' value='".$teamy."' />";
echo "<input type='submit' name='submit' align='middle' value='Refresh Match Score'/>";
echo "</form>";

there doesn't exists a tag with the name this. You have to write $(this) instead of $('this')...

But this is also wrong here, you have to pass the this (the element) into the function and then use it as "selector":

function submitForm(form)
{
    $.ajax({
        type: 'GET', 
        url: 'iccrefresh.php', 
        data: $(form).serialize(),
        dataType:'script',
        error: function()
                { $( "#dialog_error" ).dialog( "open" ); },
        success: function()
                { $( "#dialog_success" ).dialog( "open" ); }
            });
    return false;
}

And in PHP:

echo "<form name='refresh' onsubmit='return submitForm(this);'>";
echo "<input type='hidden' name='team1' value='$teamx' />";
echo "<input type='hidden' name='team2' value='$teamy' />";
echo "<input type='submit' name='submit' align='middle' value='Refresh Match Score'/>";
echo "</form>";

You should not enclose this in quotes, $('this') will find the tag name this and will not refer to current form object.

Change

data: $('this').serialize(),

To

data: $(this).serialize(),

Also you are using javascript to bind event, so you need to pass the source explicitly.

Html

echo "<form name='refresh' onsubmit='return submitForm();'>";  

Javascript

function submitForm(formobj)
{
    $.ajax({
        type: 'GET', 
        url: 'iccrefresh.php', 
        data: $(formobj).serialize(),
        dateType:'script',
        error: function()
                { $( "#dialog_error" ).dialog( "open" ); },
        success: function()
                { $( "#dialog_success" ).dialog( "open" ); }
            });
    return false;
}

Remove datatype 'script'. You are getting back html from the request, so jquery should parse it for you
