如何删除动态生成的DIV的lastchild元素并将html作为字符串返回

Question

How to remove the lastchild of the dynamically generated div and regenerate the html as string. Sample HTML DIV

strHtmlString = "<div contenteditable='true' id='undefined'>Test1</div>
    <div contenteditable='true' id='sentenceFreeTextField67' type='sentenceFreeTextField'>One</div>
    <div id='multiselectAnchors' type='multi'>
        <div id='options32' >Two</div>
        <div contenteditable='true' id='sentenceFreeTextField68' type='sentenceFreeTextField'>One</div>
    </div>
    <div id='blank4' contenteditable='true' type='blankField'>&nbsp;&nbsp;&nbsp;</div>
    <div id='Div1' type='multi'>
        <div id='options33' >Three</div>
        <div contenteditable='true' id='sentenceFreeTextField69' type='sentenceFreeTextField'>One</div>
    </div>"

here is the code sample

if (($('<DIV/>').html(strSentence)[0].lastChild.lastChild.type === 'sentenceFreeTextField') && (!$.trim($('<DIV/>').html(strSentence)[0].lastChild.lastChild.innerText))) {

strHtmlString = $('<DIV/>').html(strSentence)[0].lastChild.lastChild.remove().html; (this remove().html doesn't work) 

}

the need is to delete the lastchild of the div at runtime and convert back to string as it was earlier. I can do string manipulation however, might not the be the right way, please suggest

Answer 1

var el = $(strHtmlString);
// dont know what you meant by last child, so taking the id
el.children().find("#sentenceFreeTextField69").remove();

var str = el.wrap("<div/>").parent().html()

Answer 2

Generate a DIV dynamically:

$('body').append('<div>');

Access the DIV immediately after generation:

var $divElement = $('body').append('<div>').find('div');

Get the last child:

var $lastChildElement = $divElement.last();

Get the HTML of the last child (more specifically, the innerHTML ):

var $lastChildHTML = $lastChildElement.html();

Do it all together then you turn around:

var $lastChildHTML = $('body').append('<div>').find('div').last().html();

That's what it's all about.

Answer 3

var last = $(element).children(':last-child');
var html = $(last).html();
$(last).remove();
var newHtml = $(element).html();
//incase you want the html with it's parent as well do this
var newHtml = $(element).parent().html();
