Codeigniter使用ajax插入数据

Question

我正在使用Ajax for CRUD。如何使用关联数组与Ajax插入数据，所以我不必重新加载页面并将插入的数据附加到现有数据下面？

这是JS

function addTextBox(section, id_group) {
row_section = "#row_" + section;
wrapper = $(row_section);
// $(wrapper).append('<div class="movement_group"><input type="text" class="title_group" name="title_detail[' + section + ']" placeholder="Input" required="" style="width: 300px" /><button type="button" style="margin-left:10px;" class="btn btn-sm sending">Ok</button><button type="button" onClick="remove_field(\'' + section + '\')" style="margin-left:10px;" class="btn btn-sm remove_content">X</button></div>'); //add input box
// $(wrapper).append('<ul id="' + section + '" class="input_fields" style="list-style-type:none"><li><div class="movement_group"><input type="text" class="title_group" name="title_detail[\'' + section + '\']" placeholder="Input" required="" style="width: 300px" /><button type="button" style="margin-left:10px;" class="btn btn-sm sending">Ok</button><button type="button" onClick="remove_field(\'' + section + '\')" style="margin-left:10px;" class="btn btn-sm remove_content">X</button></div></li></ul>'); //add input box
$(wrapper).append('<ul id="fail_' + section + '" class="input_fields" style="list-style-type:none"><li><div class="movement_group"><input type="text" id="txt_' + section + '" id_group = "' + id_group + '"class="title_group" name="title_detail[\'' + section + '\']" placeholder="Input" required="" style="width: 300px" /><button type="button" style="margin-left:10px;" class="btn btn-sm sending" onClick="saveTitleGroup(\'' + section + '\', \'' + id_group + '\')">Ok</button><button type="button" onClick="remove_field(\'' + section + '\')" style="margin-left:10px;" class="btn btn-sm remove_content">X</button></div></li></ul>'); //add input box }

function remove_field(section) {
    section_id = "#fail_" + section;
    $(section_id).remove(); }

function saveTitleGroup(section, id_group) {
title_group = "#txt_" + section;
title_group = $(title_group).val();
td_section = "#td_" + section;
row_section = "#row_section" + section;

$.ajax({
type: "POST",
url: adminUrl+"/interest/save_detail",
data: {title: title_group, interest_group_id: id_group}, 
dataType: "text",
cache:false,
success: 
    function(data, textStatus, jqXHR){
        console.log('test');
        console.log(row_section);
        /*$('.movement').fadeOut(800, function(){
            $('.movement').fadeIn().delay(500);
                // $('.movement').reload('http://127.0.0.1/camtravel-web/administrator/interest');
                // return data;
                window.location.reload();
        });*/
        // console.log(row_section);
        // console.log(title_group);
        // $('#tableinterest').html('');
        $(td_section).html(data);
        // $(row_section).html(''');
      }
  }); }

Answer 1

在定义字符串时使用单引号$string = '<div class"dre"></div>'和关联数组需要引号名称$array['name']而不是$array[name]并且最后正确地连接字符串和变量。

试试这个：

<table id="tableinterest" class="table table-bordered table-striped">
                <thead>
                    <tr>
                        <th>No</th>
                        <th>Name</th>
                    </tr>
                </thead>
                <tbody>
                    <?php
                    $n=0;
                        foreach ($interest_groups as $interest_group) {
                    $n++;   
                            echo "<tr>";
                            echo "<td>";
                            // echo $interest_group['id'] . ". " 
                            echo $n . ". ";
                            ?>

                            </td>
                            <?php
                                echo "<td id='td_section_".$interest_group['id']."' group-id='".$interest_group['id']."'>";
                                echo "<b style='font-size:11pt !important;'>" . $interest_group['title'] . "</b>" .

                                foreach ($interest_details as $interest_detail) {
                                    echo "<ul style='list-style-type:none'>";
                                    if ($interest_detail['interest_group_id'] == $interest_group['id']) {

                                    }
                                    echo "</ul>";
                                }

                                    echo "<div id='row_section_".$interest_group['id']."'></div>";
                            echo "</td>"
