通过ajax提交信息时遇到问题。
例如有20行。单击行，它将打开有关服务的所有信息。
$('tr').click(function() {
var servicesUpdateId = $(this).attr('data');
$("#"+servicesUpdateId).css({"display":"block", 'opacity':'0'}).animate({left: '0',opacity: '1',});
// save form class for ajax submit
localStorage.setItem("formId", servicesUpdateId);
});
这里是html：
<tbody>
<?php
$allServices = Services::where('user_id', $mainUser->id);
foreach($allServices as $oneServices) {
?>
<tr class="services-table-hover" data="services_<?php echo $oneServices->id; ?>">
<td> <div class="services-color"></div> <img src="/assets/images/provider_img2.png" alt=""> </td>
<td class="title-name"> <?php echo $oneServices->name; ?> </td>
<td> <?php echo $oneServices->description; ?> </td>
<td> <?php echo $oneServices->duration; ?> mins </td>
<td> <?php echo $oneServices->currency; ?> <?php echo $oneServices->price; ?> </td>
<td style="line-height: 50px;"> <i class="icon-arrow-right"></i> </td>
</tr>
<?php } ?>
然后它的div与信息
<?php foreach($allServices as $onesServices) { ?>
<div id="services_<?php echo $onesServices->id; ?>">
<div class="portlet light minHeigh staff-hover">
<form action="" method="post" class="services_<?php echo $onesServices->id; ?>">

我正在localStorage中保存课程。然后用户在字段中编辑值并离开该字段，我用ajax
更新该信息 $('.'+localStorage.getItem("formId")+' input, .'+localStorage.getItem("formId")+' textarea').blur(function(event) {
var updateStaffId = $("."+localStorage.getItem("formId")+" .all-around-on input[name='update_staffs_id[]']").map(function(){return $(this).val();}).get();
var updateCategoriesId = $("."+localStorage.getItem("formId")+" select[name=update_services_category] option:selected").map(function(){return $(this).val();}).get();
var formData = {
'from' : 'serviceUpdate',
'user_id' : '<?php echo $mainUser->id; ?>',
'services_id' : localStorage.getItem("formId"),
'update_services_name' : $('.'+localStorage.getItem("formId")+' input[name=update_service_name]').val(),
'update_services_description' : $('.'+localStorage.getItem("formId")+' textarea[name=update_service_description]').val(),
'update_services_price' : $('.'+localStorage.getItem("formId")+' input[name=update_service_price]').val(),
'update_services_duration' : $('.'+localStorage.getItem("formId")+' input[name=update_service_duration]').val(),
'update_services_category' : updateCategoriesId,
'update_services_staff' : updateStaffId
};
$.ajax({
type : 'POST',
url : 'ajax/ServicesAjax.php',
data : formData,
dataType : 'json',
encode : true
})
// using the done promise callback
.done(function(data) {
if(data['success'] == true) {
toastr.success("Information updated successfuly!", "Services");
}
})
// using the fail promise callback
.fail(function(data) {
// show any errors
// best to remove for production
console.log(data);
});
// stop the form from submitting the normal way and refreshing the page
event.preventDefault();
});
问题是它只适用于最后一行。第一行，第二行，第5行，然后打开信息并编辑字段值，模糊不起作用。但最后一行效果很好。问题出在哪里？

问题解决，我在$('tr').click中添加了我的ajax，并使用var servicesUpdateId = $(this).attr('data');更改了localStore。也许问题是localStore。但在控制台中，它始终显示真正的价值。
答案 0 :(得分：1)
替换
$('.'+localStorage.getItem("formId")+' input, .'+localStorage.getItem("formId")+' textarea').blur(function(event) {
与
$('.'+localStorage.getItem("formId")+' input, .'+localStorage.getItem("formId")+' textarea').on("blur",function(event) {
由于.blur（）函数仅与页面加载期间第一次加载的元素绑定。
但是当你使用ajax在现有页面中创建html新元素时，你需要再次绑定事件，但这看起来很无聊。
为此使用jQuery.on（），并将事件名称作为第一个参数传递，并保持与.bind（）/。click（）或任何其他事件函数相同。
因此最好使用jQuery.on（“eventName”）。
