How can I dynamically create an unordered list in JavaScript?

Question

I have a global JavaScript array containing several lines.

I want to create a dynamic list based on strings in my JavaScript array. Similar to this:

<ul class='xbreadcrumbs' style='position:absolute; bottom:0px'>
    <li>
        <a href='#'>String 1</a>
    </li>
</ul>

How can I iterate over my array and then create this list in JavaScript / jQuery?

Answer 1

try it

var str = '<ul class='xbreadcrumbs' style='position:absolute; bottom:0px'>';

for(var i in $yourArray){
   str += '<li><a href="#">String 1</a></li>';
}

str += '</ul>';

$('body').append(str);

Answer 2

If you only need a flat array (i.e. not multidimensional and without arrays inside the array), you can do the following in simple JavaScript:

var strs = [ "String 1", "String 2", "String 3" ];
var list = document.createElement("ul");
for (var i in strs) {
  var anchor = document.createElement("a");
  anchor.href = "#";
  anchor.innerText = strs[i];

  var elem = document.createElement("li");
  elem.appendChild(anchor);
  list.appendChild(elem);
}

Then add listto any parent element in the body that you desire.

var $bread = $('ul.xbreadcrumbs');
$.each(yourArray, function(index, value) {
  $('<li><a href="#">' + value + '</a></li>')
    .appendTo($bread);
});

Yes, you can. You can directly use the DOM with createElement(see Jonathan's answer) or go through a very simple route using jQuery (not tested):

var ul = "<ul>";
for(var i=0; i < arr.length; i++) {
    ul += "<li><a href=\"#\">" + arr[i] + "</a></li>";
}
ul += "</ul>";

var ulElem = $(ul);
