javascript - Dynamically change div height with window resize -


i wanted change height of div when window resized. know can done css using height:100%; doesn't work on need. wanted make happen in pure javascript without jquery or other framework.

here have done:

<div id="left"> <div id="inner">  </div> </div>

css

#left{  margin-top:40px; width:200px; height:576px; background:white;  } #inner{  height:100%; overflow-y:scroll; }

javascript

window.onload= window.onresize=function(){ var left=document.getelementbyid('left'); var window_height = window.innerheight; if ( window_height > 600px ) { left.style.height = document.body.offsetheight +"px";    }  else { }  }

the div id left has have same margin. wanted change height of div match inner window height (in px no %).

thank you.

window.innerheight should window.innerheight (capital h). note ie doesn't support prior ie9.

also note you're comparing element number here:

if ( left < window_height ) //   ^--- element

you wanted height left instead, condition never true.

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...
