I’m “developing” a web site from Sharetribe (this is a website to create marketplaces). Sharetribe limited the “freedom” of a developer. We can add anything to the <head> of the website. So in the <head> I can change the CSS of the website, and this is great because I can change the appearance of the website.
What I’d like to do is to add HTML tags, like buttons, divs, etc. If I can do that, it would be great.
I believe this can’t be done, but first, I’d like to question — who knows, maybe I’m wrong.
It's a bit hacky, but you can use javascript to "insert" or "append" html to the body of the webpage through the head.
If you only have access to the head element, but not to the body, then you could try to use Javascript to add elements into the body. This only works if script tags are allowed and it has to be said that it is not really a good way of coding. But if it is the only way...
My idea (to make it a bit easier) : Include jQuery and add elements to the body by using the append function. So: you go to the jQuery downloads page, download the file and include it in the head tag. Now, you can access the body tag and insert some custom code like this:
$("body").append('<h1>Hi! I am a headline</h1>');
Pure JavaScript way:
var sibling = document.querySelector('.sibling');
var newSibling = document.createElement('div');
newSibling.className = 'sibling';
newSibling.innerHTML = 'Appended before the below div';
document.body.insertBefore(newSibling, sibling);
<body>
<!-- Already Existing HTML -->
<div class="sibling">I wish I had a sibling</div>
</body>
Quick jQuery way:
Include jQuery inside your head. Include the custom jQuery code inside <script></script> within <head>.
$(document).ready(function() {
$('.sibling').append('<div class="sibling">Hey! I am here</div>');
$('.child').wrap('<div class="child">You are not orphan anymore!</div>');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<!-- Already Existing HTML -->
<div class="child">I wish I had a parent</div>
<div class="sibling">I wish I had a sibling</div>
</body>

I'm not good with script and I can't figure out what's going wrong with my execution.
The webpage is http://snmcsupport.com/map-js-test-page and it should be running a script that produces a clickable map. The script itself is extremely long so I won't paste it here, but you can see it if you click here
On my webpage, I have the markup necessary to run the script in the header
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">
</script>
<script src="//cdnjs.cloudflare.com/ajax/libs/raphael/2.1.4/raphael-min.js">
</script>
<script src="//cdnjs.cloudflare.com/ajax/libs/qtip2/2.1.1/jquery.qtip.min.js">
</script>
On my webpage, I call the script
<div>
<script type="text/javascript" src="http://snmcsupport.com/wp-includes/js/app.js">
</script>
</div>
But I still can't get the code to run? The initial instructions from the developer also said:
The last step is to initialize the map by making the following script calls:
<script>makeaClickableMap.initialize(<your-document-object-model-handle>);</script>
where your-object-document-model handle can be anything actually:
a jQuery object like $("#map")
a Javascript Document Object Model like document.getElementById("map")
or a simple string like "map"
but I can't figure out what that means. If I try to put in the initialize command in my webpage I get a nasty cross-scripting error and it won't let me.
I'm running this on Wordpress using a Divi Child theme.
makeaClickableMap.initialize(<your-document-object-model-handle>);
//this is the element that will --^
//be used to contain your rendered map
The method makeClickableMap.initialize() expects you to pass it a reference of an HTML element where you want the map to appear. Elements can be identified by
their tag name (div, p, h1, etc.)
a class name <div class="className></div>
OR by id name, which I will demonstrate here:
Firstly, you;ll need an element with an ID associated with it, it should be placed inside the <body> tag:
<div id="map"></div>
underneath this tag, but still within the body tag, you'll need to include the makeClickableMap.initialise call and pass in the ID of this <div>:
<!-- Javascript solution: -->
<script>
makeaClickableMap.initialize(document.getElementById('map'));
</script>
<!-- notice that the id is just 'map' here -->
An alternative to the Javscript solution above is using jQuery as follows (you'll still need the div with the ID):
<!-- jQuery solution: -->
<script>
makeaClickableMap.initialize($('#map'));
</script>
<!-- notice the ID is prefixced with a '#' character-->
I've been running into some problems that seem to arise from making my questionnaire a .PHP file rather than an .HTML. The reason I had to do this is because I'm using a PHP script for working with an SQL database and I had to include them into the Questionnaire, which won't work as an HTML.
In the HTML version everything runs perfectly the way I coded it. When I saved it as a .php file my javascript stopped working properly and I tried linking the javascript at the bottom of the body tag instead of the head and that still didn't help.
After a lot of going back and forth trying to see what's different I decided to save the .php file as an html just for grins and giggles to see if I still got the same problems. Oddly enough, it runs just as smooth as the other HTML file.
here's links to all 3 versions so you can see what I mean.
HTML v1
PHP
HTML v2
In the JS Console I got this error
Uncaught TypeError: Cannot set property 'onClick' of null
which referred me to line 163 of my .js file which is referencing the "next" button of the first page of the Questionnaire (not intro page that loads up but the next page where you actually input data).
The way I have the Questionnaire structured in the .PHP file is
<?php ini_set('display_errors','on'); ?><?php include('extlib/vdaemon/vdaemon.php'); ?><!doctype html>
<html>
<head>
//links to files etc.//
</head>
<header>
</header>
<body>
<form action="core/process.php" method="post" id="CorpID" runat="vdaemon">
<input type="hidden" name="formID" value="Questionnaire" />
<input type="hidden" name="redirect_to" value="http://optiqvision.x10host.com/Corp_ID_&_Branding_Questionnaire.html" />
//all form inputs//
</form>
<?php VDEnd(); ?>
</body>
<footer>
</footer>
</html>
The entire Questionnaire has well over 100 individual inputs so I didn't want to put all of them in this snippet. I just wanted to show the over all structure, plus I figured you could get more details in the browser from clicking on them and looking at the debugger to see more of what's going on. Can anyone identify what I'm doing wrong with the PHP? I really don't understand why it's messing up the way it is.
In your html the code for the textarea is like this:
<textarea id="my_comp" class="tex_inp01" style="width:88%; height:100px; font-size:14pt;"></textarea>
In your php the
The textarea closing tag is misplaced; coming after a lot of div's including the element with the id=p1_next. SO the divs just become part of the textarea value instead of being part of the HTML page
Edit: Looks like the real problem is that the DOM is broken. In your PHP file, you have a self-closed textarea tag. textarea tags need a closing tag.
<!-- you have this, it's not syntactically correct -->
<textarea id="my_comp" class="tex_inp01" style="width:88%; height:100px; font-size:14pt;" />
<!-- the following is correct -->
<textarea id="my_comp" class="tex_inp01" style="width:88%; height:100px; font-size:14pt;"></textarea>
Put Corp_ID_&_Branding_Questionnaire.js right before the body tag and it will work. The reason the PHP file is throwing a javascript error is because the node "p1_next" doesn't exist at runtime since your JS is in the head tag.
The reason it's working in the HTML file is mainly thanks to luck. The static HTML is loading fast enough that the DOM is ready by the time your JS code is running. As a thumb of rule, generally include all your JS right before the body tag. There are of course some exceptions.
If you really need to include your script in the head, you can wait until the DOM is ready by wrapping all your code with this:
$(document).ready(function() {
console.log( "ready!" );
// your JS code here
});
Last, if you're going to be using jQuery as a library, then it is recommended to use jQuery syntax instead of native JS. Just make sure to include the jQuery JS before your code.
var p1a = document.getElementById("p1_next");
// becomes:
var p1a = $('#p1_next'); // jQuery node by CSS selector
Before the end of the body tag like this:
<html>
<head>
..your code ..
</head>
<body>
..your code ..
<script type="text/javascript" src="http://www.optiqvision.x10host.com/Files/Javascript/Corp_ID_&_Branding_Questionnaire.js"></script>
</body>
</html>
So I'm working on my online portfolio using prosite.com and I created some simple hover thingy using javascript (http://wojtek.szukszto.com/index.html). The problem is prosite.com won't allow me to use < script > tag... Is there any way to do it? Maybe as an external html? I don't know... I'm not really good in coding, so any help would be appreciated.
You can have them as DOM Events like
<div onclick="alert('cat');">
I <strong>Really</strong> want a cat!
</div>
<body onload="//you can put a whole bunch of stuff here"></body>
(It is equivalent to window.onload = function(){ //stuff })
You can put your javascript code into external file and call in the head section of your html document
<head>
<script src ="/JS/yourjsfile.js"></script>
</head>
hope that your host allows you to call JS in the head section
The way I do it is by stating the type of script. The ProSite already has javascript integrated within itself. I use:
<script type="javascript"> Code-Goes-Here </script>
I am creating a website (http://yic.am) using wordpress and the theme includes a background and a "subpage_content_bg". The subpage-background is a semi-transparent white background that wraps around the content making it easier to read. I would like the subpage background to become position:fixed instead of position:absolute when you scroll down, so that when it reaches the top of the page it scrolls with the page.
I have found several pages describing and demonstrating the function when the subject is a picture, comment box or text in the actual post or page. However, I cannot seem to find a description for when the picture is a part of the css stylesheet.
The subpage-extract from the stylesheet looks like this:
#sp .content_wrapper_sbl {
width:940px;
min-height:320px;
margin:-107px auto 0;
padding:45px;
position:relative;
z-index:20;
background:url(../../images/subpage_content_bg.png) 0 0 no-repeat;
}
Where should I place the javascript for the function (I am trying to use the function from the above link)? I would like it to be for all pages and posts (except the cover-page)
How do I make the subpage image the target of the function? Is it possible to make the #sp or content_wrapper_sbl the target?
I have been trying a lot of different things for a lot of times - but I am very new to web-designing and coding. I hope all the necessary information is included - any help would be much appreciated.
The code I am working is this: http://jsfiddle.net/EahRx/870/
It looks like you've pretty much got it nailed in that fiddle, haven't you? It's personal preference how you want to arrange your javascript files, I guess. Personally, I like to use the Google library to load my jQuery...
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
and then load any other plugins you might be using...
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
and finally I usually build a custom jQuery file and call it, surprise surprise, "jquery.custom.js"...
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
So the final javascript include list looks like this...
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
This way the jQuery library is loaded first because the likelihood is that all other javascript files depend on it. Then the plugins are loaded, finally your custom file is loaded because that might depend on some of the earlier plugins being loaded first - for example, your custom file might want to tweak a slideshow file loaded in one of your plugins.
If, for any reason, you are not able to edit the head of your template file to add your javascript include you can add it to the bottom of your HTML like this...
<head>
[META INFO & TITLE]
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
[CSS AND STUFF]
</head>
<body>
[YOUR WEB PAGE STUFF]
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
</body>
</html>
Hope this helps point you in the right direction.
Oh, and remember to add the old "document ready" gubbins to the jquery.custom.js file too...
$(document).ready(function(){
[YOUR JQUERY HERE]
});
I'm looking to do a short term hack on a site. The site is a ASP.NET site with a master page. The body tag is in the master page. I'd like to specify which ID should be in the body tag from within various content pages. What I don't know is if you can have this type of access to the body tag when your JS is within the body tag. For various reasons, I'd like to try to accomplish this in JS, not .NET.
Any tips?
Rephrasing for clarity:
I would like to use JavaScript to specify a body ID from within the body tag of a site. For example:
<body id="MyID">
JS to change MyID to another name
</body>
Put this in the Page_Load of any ContentPage...
string JS = "document.body.id = 'WhateverID';";
ClientScript.RegisterStartupScript(this.GetType(), "BodyID", JS, true);
