上下移动Ul Li中的项目

Question

I have a Ul li and on click of a Up and Down buttons I want to move to move the li elements up and down. Here is the html that is rendered on the page.

I already tried the solution mentioned in the link Can I use jQuery to easily shift li elements up or down? but it didn't work for me.

      <ul id="ul_li_SubCategories" style="width:200px;" class="chargeCapturetable margin0">
    <li sequence="1" title="Category 1" class="liEllipsis" value="9"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 1</a></li>
    <li sequence="2" title="Category 3" class="liEllipsis" value="11"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 3</a></li>
    <li sequence="4" title="Category 4" class="liEllipsis" value="12"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 4</a></li>
    <li sequence="5" title="Category 6" class="liEllipsis" value="22"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 6</a></li>
    <li sequence="6" title="Category 5" class="liEllipsis" value="13"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 5</a></li>
    <li sequence="7" title="Category 7" class="liEllipsis" value="55"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 7</a></li>
<li sequence="99999" title="Category 8" class="liEllipsis" value="62"><a href="#"><span class="viewIcons delFaceName _delete fl"></span>Category 8</a></li></ul>

Answer 1

Look at this jsfiddle

Use this jQuery code, I just move elements down in this example:

$.fn.moveUp = function() {
    before = $(this).prev();
    $(this).insertBefore(before);
}

$.fn.moveDown = function() {
    after = $(this).next();
    $(this).insertAfter(after);
}

$('li').click(function() {
    $(this).moveDown();
});

I just got the example from here

You can try something like the following:

$('.upbutton').on('click', function () {
    var hook = $(this).closest('.liEllipsis').prev('.liEllipsis');
    var elementToMove = $(this).closest('.liEllipsis').detach();
    hook.before(elementToMove);
});
$('.downbutton').on('click', function () {
    var hook = $(this).closest('.liEllipsis').next('.liEllipsis');
    var elementToMove = $(this).closest('.liEllipsis').detach();
    hook.after(elementToMove);
});

If you want to move using a button outside, and a selected li element, try something like this:

$('.liEllipsis').on('click', function () {
    $('.selected').removeClass('selected');
    $(this).addClass('selected');
});

$('.upbutton').on('click', function () {
    var $currentElement = $('#ul_li_SubCategories .selected');
    moveUp($currentElement);
});

$('.downbutton').on('click', function () {
    var $currentElement = $('#ul_li_SubCategories .selected');
    moveDown($currentElement);
});

var moveUp = function ($currentElement) {
    var hook = $currentElement.prev('.liEllipsis');
    if (hook.length) {
        var elementToMove = $currentElement.detach();
        hook.before(elementToMove);
    }
};

var moveDown = function ($currentElement) {
    var hook = $currentElement.next('.liEllipsis');
    if (hook.length) {
        var elementToMove = $currentElement.detach();
        hook.after(elementToMove);
    }
};

you can try this

 $(function(){ $('.glyphicon-arrow-up').on('click', function(e){ e.preventDefault(); var _this = $(this); var _parent = _this.closest('ul'); var _child = $(_parent).find('li'); var selected= $(this).closest('li').index(); jQuery($(_parent).children().eq(selected-1)).before(jQuery($(_parent).children().eq(selected))); }); $('.glyphicon-arrow-down').on('click', function(e){ e.preventDefault(); var _this = $(this); var _parent = _this.closest('ul'); var _child = $(_parent).find('li'); var selected= $(this).closest('li').index(); jQuery($(_parent).children().eq(selected+1)).after(jQuery($(_parent).children().eq(selected))); selected=selected+1; }); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul> <li>Sample 1 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 2 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 3 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 4 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 5 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 6 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> <li>Sample 7 <span class="glyphicon-arrow-up">Up</span><span class="glyphicon-arrow-down">Down</span></li> </ul> 

Answer 4

You can use insertAfter() and look the for sequence / manipulate the sequence

In your function you should do something like

var previousObject = $(this).prev('li');
$(this).insertBefore(previousObject);


var nextObject = $(this).next('li');
$(this).insertAfter(nextObject);

not tested. But something like that should work. (this is the clicked list object)

Answer 5

Here is a vanilla JS solution to your question using your supplied HTML markup.

The solution makes use of the .insertBefore() method on the parent <ul> to move the selected <li> element up or down.

<li> items are selected by using the event object to track which button was clicked.
