Apologies if this is a very basic mistake, but I looked around and couldn't find an answer. I am trying to use document body appendchild cannot read property appendchild of null the appendChild method to add a heading and some paragraph text into the in the very basic HTML file below.
Simple HTML Page
This is a very simple HTML page.
It's about as basic as they come. It has:
- An H1 Tag
- Two paragraphs
- An unordered list Here is the js code: var newHeading = document.createElement("h1"); var newParagraph = document.createElement("p"); newHeading.innerHTML = "New Heading!"; newParagraph.innerHTML = "Some text for a paragraph."; document.getElementById("javascript").appendChild(newHeading); document.getElementById("javascript").appendChild(newParagraph); Running it causes an error: "Cannot call method 'appendChild' of null" Help?

I've been doing some JS recently, but now I'm stuck on an error, which nature I don't really understand. I understand there are quite a few of threads like that, but all the solutions I've found don't seem to work in my case. So here's the code: function codeInsert() { var overcodeMake = document.createElement("div"); overcodeMake.id = "overcode"; var body = document.getElementById("body"); body.appendChild(overcodeMake); var undercodeMake = document.createElement("input"); undercodeMake.id = "undercode"; undercodeMake.type = "text"; undercode.placeholder = "CODE"; var overcodeMade = document.getElementById("overcode"); overcodeMade.appendChild(undercode); } All the IDs are on positions, everything looks logical, yet I keep getting the "Cannot read property 'appendChild' of null" error. What could be the reason? Or do I not understand something here? javascript null appendchild share|improve this question asked Jun 14 '15 at 22:27 Twixes 113 marked as duplicate by Bergijavascript Users with the javascript badge can single-handedly close javascript questions as duplicates and reopen them as needed.

I don't have the SEO metabox neither, but I don't know why, it should be visible... If I hide the metabox for this post type in the settings, this error disappears. Any clue ? Yoast member Rarst commented Nov 26, 2015 Please include error in full, especially file and line where it appears. If you could enable SCRIPT_DEBUG in configuration that will make non-minified script files load and information more precise. Rarst added wait for feedback javascript labels Nov 26, 2015 jbjanot commented Nov 26, 2015 Hi ! Sure, but is there a way to make the plugin load non minified scripts ? I tried wp_debug and debug_scripts, but it is still loading minified files. Yoast member Rarst commented Nov 26, 2015 SCRIPT_DEBUG is supposed to do exactly that. jbjanot commented Nov 26, 2015 Well, i'm sorry but I can't manage to make the plugin load unminified files... The error in the minified version is happening here : document.getElementById(this.config.targets.output).appendChild(a); The complete error is this : Uncaught TypeError: Cannot read property 'removeChild' of null In this file : yoast-seo-302.min.js Does it help ? Yoast member Rarst commented Nov 26, 2015 Yes, thank you for details. It's pretty strange to occur since 3.0.4 specifically improved cases when editor is absent. Could you elaborate a bit on what exactly are you doing with that? seripap commented Nov 26, 2015 The fix for this has an open PR in YoastSEO.js Rarst added has patch and removed wait for feedback labels Nov 26, 2015 zrothauser commented Nov 27, 2015 I'm getting this as well, when trying to edit Media posts. It happens even with no other plugins activated with the Twenty-Fifteen theme. Also, I believe the @seripap's patch is for a different issue - I'm no
