Get an array of list element contents in jQuery

Question

I have a structure like this:

  
text1
  
text2
  
text3

Answer 1

Without redundant intermediate arrays:

arr = $('li').map(function(i,el) {
    return $(el).text();
}).get();

See jsfiddle demo

Answer 2

And in clean javascript:

var texts = [], lis = document.getElementsByTagName("li");
for(var i=0, im=lis.length; im>i; i++)
  texts.push(lis[i].firstChild.nodeValue);

alert(texts);

Answer 3

You may do as follows. one line of code will be enough

• let array = $('ul>li').toArray().map(item => $(item).html());

• Get the interested element

  1. get children

  2. get the array from toArray() method

  3. filter out the results you want

let array = $('ul>li').toArray().map(item => $(item).html());
console.log(array);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
  <li>text1</li>
  <li>text2</li>
  <li>text3</li>
</ul>

Answer 4

var arr = new Array();

$('li').each(function() { 
  arr.push(this.innerHTML); 
})

Answer 5

var optionTexts = [];
$("ul li").each(function() { optionTexts.push($(this).text()) });

...should do the trick. To get the final output you're looking for, join() plus some concatenation will do nicely:

var quotedCSV = '"' + optionTexts.join('", "') + '"';

Answer 6

kimstik was close, but not quite.

Here's how to do it in a convenient one-liner:

$.map( $('li'), function (element) { return $(element).text() });

Here's the full documentation for jQuery's map function, it's quite handy: http://api.jquery.com/jQuery.map/

Just to answer fully, here's the complete functionality you were looking for:

$.map( $('li'), function (element) { return $(element).text() }).join(', ');
