Question

我已经使用jQuery函数来刷新div但是当我提交表单不止一次页面将被刷新。我想停止刷新，并显示像Facebook评论更新的新内容。请帮我解决这个问题。

这是我的代码：

<div class="row">
   <div id="right-side" class="col-lg-9 col-md-9 col-sm-8 col-xs-12">
        <div id="profile_container">
            <div class="profile_items">
                <ul class="profile_ul">
                    <li id="personal-info">
                        <div class="profile_content">
                            <form action="" method="POST" id="personal-info-form" class="form-group">
                                <table>
                                <?php   foreach ($personal as $pdata) { ?>
                                <tr id="new_personal" class="pro-info-set">
                                    <td class="info-group-left">

                                    </td>
                                    <td class="info-group">
                                        <p class="pro-info-right"><?php echo $pdata['js_personal_desc']; ?></p>
                                    </td>

Answer 1

试试这个：

$("#submit_person").click(function(e){
    e.preventDefault();
    $(this).prop('disabled', true); //<---disabled it here
    var data = { // instead you can send an object too
        js_personal_title : $("#js_personal_title").val(),
        js_personal_desc  : $("#js_personal_desc").val()
    }
    $.ajax({
        type: "POST",
        url: "<?php echo base_url().'index.php/Jobseeker/add_personal' ?>",
        data: data,
        success:function() {
            $("#personal-info-form")[0].reset();
            $(".row").load(location.href  + " #new_personal", function(){
                $("#submit_person").prop('disabled', false); // now enable it here.
            });
            $( "#submit_person_msg" ).append( "<p> Loading... </p>" );
        },
        error: function(){ 
            $("#submit_person").prop('disabled', false); // now enable it here. 
        }
    });
});

在我看来，问题是用户能够发送多个请求，因此您可以在单击时disable按钮，并在数据附加到DOM中时启用它。

更新

您可以使用.load(url, cb)功能的回调功能启用禁用按钮，以确保加载内容并且您可以再次单击提交按钮。

$(".row").load(location.href  + " #new_personal", function(){
     $("#submit_person").prop('disabled', false); // now enable it here.
});

另一个建议是为每个元素添加唯一ID或将其更改为类名。我可以看到你正在重复php循环中的ID：

   <?php   foreach ($personal as $pdata) { ?>
    <!-- <tr id="new_personal" class="pro-info-set"> -->
    <tr class="pro-info-set new_personal">
        <td class="info-group-left">
            <p class="pro-info-left"><?php echo $pdata['js_personal_title']; ?></p>
        </td>
        <td class="info-group">
            <p class="pro-info-right"><?php echo $pdata['js_personal_desc']; ?></p>
        </td>
    </tr>
    <?php   } ?>

Answer 2

你应该听取表格的submit事件，而不是click倾听

$("#personal-info-form").on('submit', function(e){
e.preventDefault();
js_personal_title = $("#js_personal_title").val();
js_personal_desc= $("#js_personal_desc").val();
var datastr = 'js_personal_title='+js_personal_title + '&js_personal_desc='+js_personal_desc; 
$.ajax({
   type: "POST",
   url: "<?php echo base_url().'index.php/Jobseeker/add_personal' ?>",
   data: datastr,
   success:function() {
     $("#personal-info-form")[0].reset();
     $(".row").load(location.href  + "#new_personal");
     $( "#submit_person_msg" ).append( "<p> Loading... </p>" );
   }
 });
  return false;
})

Answer 3

我在这里找到了答案 Jquery: Click event doesn't work after append. (Don't know how to use .ON)

$(document).on('click', '.choimg', function(e) {

});

Ajax：在提交多次后阻止刷新页面
