很抱歉，我看起来很无知，但是我已经很久没有遇到这个问题了，现在我完全无法理解为什么我的JQuery函数无法正常工作。
我需要此代码将数据发送到PHP文件，我确定它可以正常工作。我曾尝试用php编写所有代码，但发现有一些地方必须包含ajax。
$(document).ready(function(){
$('#sending').on('submit', function(event){
event.preventDefault();
if(($('#receiver_id1').val() == '0') && ($('#receiver_id2').val() == '0') && ($('#receiver_id3').val() == '0'))
{
alert("Please fill in the recipient!");
return false;
}
else if($.trim($("#message").val()) == '')
{
alert("You cannot send an empty message.");
return false;
}
else if($('#subject').val() == '')
{
var retVal = confirm("Are you sure to send a message without a subject?");
if( retVal == true ) {
var receiver_id1 = $('#receiver_id1').val();
var receiver_id2 = $('#receiver_id2').val();
var receiver_id3 = $('#receiver_id3').val();
var receiver_name1 = $('#receiver_id1').text();
var receiver_name2 = $('#receiver_id2').text();
var receiver_name3 = $('#receiver_id3').text();
var from_user_name = '<?php echo $from_user_name;?>';
var from_user_id = '<?php echo $from_user_id;?>';
var subject = $('#subject').val();
var message = $('#message').val();
$.ajax({
url:"messaging.php",
type:"POST",
data:{receiver_id1:receiver_id1, receiver_id2:receiver_id2, receiver_id3:receiver_id3, receiver_name1:receiver_name1, receiver_name2:receiver_name2, receiver_name3:receiver_name3, subject:subject, message:message},
success:function(data)
{
$('#receiver_id1').val("0");
$('#receiver_id2').val("0");
$('#receiver_id3').val("0");
$('#subject').val("");
$('#message').val("");
var employee_id = $(this).attr("id");
$.ajax({
url:"select.php",
type:"post",
data:{employee_id:employee_id},
success:function(data){
$('#employee_detail').html(data);
$('#popup').modal("show");
}
});
},
error: function(jqxhr, status, exception) {
alert('Exception:', exception);
}
});
} else {
return false;
}
} else
{
var receiver_id1 = $('#receiver_id1').val();
var receiver_id2 = $('#receiver_id2').val();
var receiver_id3 = $('#receiver_id3').val();
var receiver_name1 = $('#receiver_id1').text();
var receiver_name2 = $('#receiver_id2').text();
var receiver_name3 = $('#receiver_id3').text();
var from_user_name = '<?php echo $from_user_name;?>';
var from_user_id = '<?php echo $from_user_id;?>';
var subject = $('#subject').val();
var message = $('#message').val();
$.ajax({
url:"messaging.php",
type:"POST",
data:{receiver_id1:receiver_id1, receiver_id2:receiver_id2, receiver_id3:receiver_id3, receiver_name1:receiver_name1, receiver_name2:receiver_name2, receiver_name3:receiver_name3, from_user_name:from_user_name, from_user_id:from_user_id, subject:subject, message:message},
success:function(data)
{
$('#receiver_id1').val("0");
$('#receiver_id2').val("0");
$('#receiver_id3').val("0");
$('#subject').val("");
$('#message').val("");
var employee_id = $(this).attr("id");
$.ajax({
url:"select.php",
method:"post",
data:{employee_id:employee_id},
success:function(data){
$('#employee_detail').html(data);
$('#popup').modal("show");
}
});
},
error: function(jqxhr, status, exception) {
alert('Exception:', exception);
}
});
}
});
});
我真的需要帮助。我绝对需要这个脚本才能工作。预先感谢。
