javascript - 在选项卡中调用 ajax 后加载数据

标签 javascript jquery ajax

我从数据库中获取数据并使用 jquery 选项卡显示它:

<script>
$(function () {
   $( "#treeTabs" ).tabs();
});
</script>

<div id="treeTabs">
    <ul>
<?php
$hod_result = getFamilyTree();
$i = 0;
while($hod_row = mysqli_fetch_array($hod_result))
{
?>
    <li>
        <a href="#<?php echo $hod_row["staff_id"]?>" class="tab_header"><span class="closer" data-id3="<?php echo $hod_row["staff_id"] ?>"><i class="fa fa-times" aria-hidden="true"></i></span><?php echo $hod_row["longname"].' ('.$hod_row["team_role"].')' ?></a>              
    </li>
<?php $i++;} ?>
    </ul>
<?php
$hod_result_tabs = getFamilyTree();
$i_tabs = 0;
while($hod_row_tabs = mysqli_fetch_array($hod_result_tabs))
{
?>    
  <div id="<?php echo $hod_row_tabs["staff_id"]?>">
    <div class="tree" id="<?php echo $hod_row_tabs["staff_id"]?>"> 
    <ul>
    <li>

    $sv_result_list= getSupervisorRole($hod_id_list);
    ?>

        <!--</ul>-->
        <?php }} ?>
        </ul>
    </li>
    </ul>
    </div>
    <div class="input"></div>
  </div>
<?php $i_tabs++;} ?>
</div>

在每个选项卡中，我得到一棵名称树: enter image description here enter image description here

然后点击 enter image description here图标有带有用户列表的弹出窗口: enter image description here

这是对话框窗口的代码:

var addUserDlg, form;

/*create and open pop up window to create a team*/
addUserDlg = $("#addUserDialog").dialog({
    autoOpen: false,
    height: 650,
    width: 570,
    modal: true,
    position: { my: "center", at: "top" },
    buttons: {
        "Create a tree": addUser,
        Cancel: function () {
            addUserDlg.dialog("close");
        }
    },
    close: function () {
        form[ 0 ].reset();
    }
});
$(document).on('click', '.createTree', function(){
    addUserDlg.dialog("open");
    var leader_role = $(this).data("id3");              
    $.ajax({
        url: "comAssessment/hr_tree_list.php",
        method: "POST",
        data: {leader_role: leader_role},
        success: function (data) {
            $('#users').html(data);

        }
    });
});
 form = addUserDlg.find("form").on("submit", function (event) {
    event.preventDefault();
    addUser();
});

和函数 addUser:

/*function to add new user to team*/
function addUser() {
    var insert = [];
    if ($('input[name="chk"]:checked').length > 0)
    {
        $('.get_value').each(function () {
            if ($(this).is(":checked"))
            {
                insert.push($(this).val());
            }
        });
        var user_to_leader = $('#user_to_leader').val();
        var team_role = $('#team_role').val();
        insert = insert.toString();
        $.ajax({
            url: "comAssessment/hr_tree_insert.php",
            method: "POST",
            data: {insert: insert, user_to_leader:user_to_leader, team_role:team_role},
            success: function (data) {
                location.reload();
                addUserDlg.dialog("close");
            }
        });
    }
}

现在我更新了整个页面 location.reload(); 但它看起来不太好，因为它每次都会打开第一个选项卡。添加新用户后如何只更新当前选项卡？

编辑

好的，我尝试获取选项卡的索引并刷新它。我添加了测试按钮:

<button id="button">Click me</button>
<div class="test_bt"></div>

和jquery:

$("#button").click(function() {
    var current_index = $("#treeTabs").tabs("option","active");
    $("#treeTabs").tabs('load',current_index);
    $('.test_bt').html(current_index);
});

然后我从 ajax success 函数中删除了 location.reload(); 以检查我的按钮是否可以完成工作。但它不起作用。我只得到索引，没有加载发生。

function addUser() {
    var insert = [];
    if ($('input[name="chk"]:checked').length > 0)
    {
        $('.get_value').each(function () {
            if ($(this).is(":checked"))
            {
                insert.push($(this).val());
            }
        });
        var user_to_leader = $('#user_to_leader').val();
        var team_role = $('#team_role').val();
        insert = insert.toString();
        $.ajax({
            url: "comAssessment/hr_tree_insert.php",
            method: "POST",
            data: {insert: insert, user_to_leader:user_to_leader, team_role:team_role},
            success: function (data) {

                addUserDlg.dialog("close");
            }
        });
    }
}

最佳答案

你有两个选择

  1. 使用 ajax 和 javascript 在客户端创建标签的 html 内容。
  2. 将当前选项卡的 anchor 放入 url 中，以便在页面刷新时显示当前选项卡。

选项 1 需要大量工作，所以我现在要详细说明选项 2。

将您当前的选项卡初始化代码替换为:

对于 jQuery 1.11

<script>
$(function () {

    var url_hashtag_index = location.href.indexOf('#')
    var initial_tab = url_hashtag_index==-1 ? 0 : parseInt(location.href.slice(url_hashtag_index+1))

    $("#treeTabs").tabs({activate: tabSelected, active: initial_tab});

    function tabSelected(event,ui){
        var tab_index = $('#treeTabs').tabs("option", "active")
        var hashtag_index = location.href.indexOf('#')
        var url = hashtag_index==-1 ? location.href : location.href.slice(0,hashtag_index)
        location.replace(url+'#'+tab_index)
    }

});
</script>

对于 jQuery 1.9+

<script>
$(function () {

    var url_hashtag_index = location.href.indexOf('#') // check if # is un url
    var initial_tab = url_hashtag_index==-1 ? 0 : parseInt(location.href.slice(url_hashtag_index+1)) // if so get tab index

    $("#treeTabs").tabs({select: tabSelected, selected: initial_tab}); // set tab index and add listener for tab selection

    function tabSelected(event,ui){
        var hashtag_index = location.href.indexOf('#')
        var url = hashtag_index==-1 ? location.href : location.href.slice(0,hashtag_index) // remove existing tab from url
        location.replace(url+'#'+ui.index) // replace url with new tab index (replace -> no history in browser)
    }

});
</script>
