jQuery 在最后一个元素之后插入

Question

I want to add elements after the last one. My current code

<div class="find"><div id="FirstElement"> /*First element loaded first */ </div><div>

$('#AddNextElement' + id).click(function (e) {
   $('<div id="NextElement' + id +'">' + /*Add after the last element*/ + '</div>').insertAfter($("#FirstElement"));
}

Current it adds only it after the first element:

1 4 3 2

I want it to add after the last element every time:

1 2 3 4

I've followed these links and I didn't find what I'm looking for:

jQuery insertAfter last item

insertAfter specific element based on ID

jQuery: Add element after another element

Thank you in advance!.

How I fixed it:

$('#AddNextElement' + id).click(function (e) {
   $('<div id="NextElement"' + id +'>' + /*Add after the last element*/ + '</div>').insertAfter($("#FirstElement").parent().find('.Finder').last());
}

I found the .parent().find('.find').last(); then insert after the last

Answer 1

Just you need last() method

$('<div id="NextElement"' + id +'>' + /*Add after the last element*/ + '</div>')
.insertAfter($('[id^="NextElement"]').last());

Answer 2

How about adding a class to all elements? It will be easier to find the last:

$('.element-class:last').after('<div class="element-class" id="NextElement"' + id +'>' + /*Add after the last element*/ + '</div>');

This of course means that your First element must also have the class:

<div class="element-class" id="FirstElement"> /*First element loaded first */ </div>

Answer 3

找到DOM中的最后一个元素，在你的情况下它将是'NextElementxx'然后使用'after'：

$('#NextElement2').after( ..new stuff.. );

Answer 4

HTML:

<div id="FirstElement"> First element loaded first  </div>

<div id="AddNextElement">Click me</div>

JS:

var current = 0;
$('#AddNextElement').click(function (e) {
    var $el = (current == 0) ? $("#FirstElement") : $("#NextElement"+current);
    current++;
    $('<div id="NextElement' + current +'">Other element '+current+'</div>').insertAfter($el);
});

Try yourself on jsfiddle

Answer 5

one way is to store the last element.

<div id="FirstElement"> /*First element loaded first */ </div>

var lastElement = $('#FirstElement');

$('#AddNextElement' + id).click(function (e) {
    var element = $('<div id="NextElement"' + id +'>' + /*Add after the last element*/ + '</div>'));
    element.insertAfter(lastElement);
    lastElement = element;
}

Answer 6

You can try below code, it will add the new div after the last "NextElement" div

JS Code:

$(function(){
    $('#AddNextElementButton').on("click", function (e) {
        var id = $("[id^='NextElement']").length ? $("[id^='NextElement']").length+1 : 1;

        if($("[id^='NextElement']").length){
            $('<div id="NextElement'+ id +'">Add after the last element</div>').insertAfter($('[id^="NextElement"]').last());
        } else {
            $('<div id="NextElement'+ id +'">Add after the last element</div>').insertAfter($('#FirstElement'));
        }
    });
});

你可以只使用这个：

jQuery('##AddNextElement').last().after();
