php显示jquery未定义,运行PHP脚本时,jQuery函数表示未定义
我基本上是这样做的,所以当您单击按钮进行“投票”时
目前我有
clients.php
$clientInfo = "SELECT * FROM Clients ORDER BY Client ASC";
$stmt = sqlsrv_query($conn, $clientInfo);
echo "
while ($client = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC))
{
echo "
"
"
"
";
}
echo "
?>
如您在上方看到的,有一个onclick forvotUp()函数.
在页面底部,我有
并在scripts.js中(我从有关单击div运行php文件的教程中获得了voteUp()的知识)
$(document).ready(function()
{
$('.pull-me').click(function()
{
$('.panel1').slideToggle('fast')
});
$('.pull-me').click(function()
{
$('.panel2').slideToggle('fast')
});
$('.pull-me').click(function()
{
$('.panel3').slideToggle('fast')
});
$("#selection-box1").change(function()
{
document.location.href = $(this).val();
});
$(".output").click(function ()
{
var noteid = $(this).data("noteid");
var templatenoteid = $(this).data("templatenoteid");
var variablenoteid = $(this).data("variablenoteid");
if ($(this).data("noteid"))
{
$("#right-box").load("noteContent.php", {noteid: noteid});
}
else if ($(this).data("templatenoteid"))
{
$("#right-box").load("templateNoteContent.php", {templatenoteid: templatenoteid});
}
else
{
$("#right-box").load("variableContent.php", {variablenoteid: variablenoteid});
}
});
var modal = document.getElementById('login-box');
window.onclick = function(event)
{
if (event.target == modal)
{
modal.style.display = "none";
}
}
//This script votes up and down for the client
function voteUp()
{
$.get("voteup.php");
return false;
}
function voteDown()
{
$.get("votedown.php");
return false;
}
});
最后在voteup.php中
if (isset($_POST['clientid']))
{
$voteup = "UPDATE Clients SET Pos = (SELECT MAX(Pos) FROM Clients) + 1 WHERE ClientID = " . $_POST['clientid'];
$stmt = sqlsrv_query($conn, $voteup);
}
else
{
echo "No ClientID";
}
?>
当我单击带onclick =“ voteUp()”的DIV的Vote Up按钮时
为什么在控制台中出现错误,提示“ ReferenceError：未定义表决”
解决方法:
您已经确定了方法的范围.
相反,您可以将它们附加到Windows,以便可以从任何地方访问.
window.voteUp = function()
{
$.get("voteup.php");
return false;
}
window.voteDown = function()
{
$.get("votedown.php");
return false;
}
