jquery - click function to add element and update html -


if have array of table list items:

<div id="target">     <ul>         <li>list item 1</li>         <li>list item 2</li>         <li>list item 3</li>         <li>list item 4</li>     </ul> </div>

and want construct click function adds 'li' , increments inner html of each item, can write:

var listitems = $('#target ul li'); var newitem = document.createelement('li'); newitem.innerhtml = "list item " + (parseint(listitems.size()) + 1);  $("#target").click(function() {     var list = $('#target ul');     list.append(newitem); });

which works, once. why won't add list item every time click it?

simple fix... should create element inside event listener:

var list = $('#target ul');  $("#target").click(function() {     var newitem = document.createelement('li');     newitem.innerhtml = "list item " + (list.find("li").length + 1);     list.append(newitem); });

note: i've replaced .size() .length. it's faster , exact same thing :)

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
