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>
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>
This question already has answers here:
javascript <script> tag - code execution before src download
(4 answers)
Closed 8 years ago.
I am relatively new to JavaScript so this might be somewhat trivial. However I can't seem to find the answer to this question.
Say I have a JavaScript file (bar.js) with a function in it called foo(). I want to call this function (foo) inside a script tag. I would like it to work like so.
<script type="text/javascript" src="bar.js">
foo();
</script>
I am not able to get this to work. I have ran the JavaScript console with my browser and what it seems to be doing is...nothing. No syntax errors or anything.
I can run a function similarly with a button click...using the script tag above and this.
<button type="button" onclick="foo();">Click Me</button>
I could do it this way, but in the actual circumstance I need to pass parameters into the function that is being called on the button click. I can't get those recognized either. I'm sure that something to do with scope.
The way I tried this was like so...
<script type="text/javascript" src="bar.js">
var a = "blah";
var b = "blab";
</script>
.... (some more html)
<button type="button" onclick="foo(a,b);">Click me </button>
Here I get that a is undefined. Which leads me to think that it is a scope problem. The script tag is in the head section and the button is in the body section. Can you put script tags outside of the head and body tags to make global data?
Thanks for the help in advance.
I have never used jsfiddle before and was having trouble getting it to work so I'll just post and example code here.
<html>
<head>
<script type="text/javascript" src="bar.js">
</script>
<!--From what yall say I should have another script
tag here for anything else. Say some variable?-->
<script type="text/javascript">
var a = "hello";
var b = "text";
</script>
</head>
<body>
<!--This should work now?-->
<button type="button" onclick="foo(b,a)">
Click me
</button>
</body>
</html>
bar.js contents:
function foo(id,string){
document.getElementById(id).innerHTML = string;
}
I got this to work.
Thanks everyone.
You need to first include the javascript containing the function:
<script type="text/javascript" src="bar.js"></script>
and then call it in another script tag:
<script type="text/javascript">
foo();
</script>
In your example you seem to have mixed 2 notions into a single script tag which is invalid: include an external javascript file and in the body of the script tag write your code.
According to the specification:
The script may be defined within the contents of the SCRIPT element or
in an external file. If the src attribute is not set, user agents must
interpret the contents of the element as the script. If the src has a
URI value, user agents must ignore the element's contents and retrieve
the script via the URI.
So basically you should avoid such situations and have separate script tags for including external files and for writing inline js.
I've read roughly 8 different questions here on StackOverflow about this same issue. I've tried a handful of different approaches, most of which involve creating the script element and then adding attributes to it, finalizing by join, append(), appendTo, document.body.appendChild, etc.
I cannot get this script tag to show up before </body>.
Script I need to append to <body>:
<script src="http://ib.adnxs.com/seg?add=1448379&t=1" type="text/javascript"></script>
It's some marketing pixel I need to add to a site that's CMS generated. It has to show up only on ONE page based on the document.location.pathname.
Have you tried?
$("body").append($("<script>", { src : "http://ib.adnxs.com/seg?add=1448379&t=1", type : "text/javascript" }))
I think this will help you
$("<script"+ " src"+"\="+ "http:\//ib.adnxs.com\/seg\?add=1448379&t=1"+" type"+"="+"text\/javascript"+"></script>").appendTo($("body"));
add \ to escape special characters
appendTo() will append just before end of body tag

I'm very new to JavaScript (just started a few hours ago and trying to get a script working). I went through a few tutorials on W3 and the 'hello world' code works when I paste it directly into my HTML but I'm having a problem with a script (I've had problems with other scripts as well but I am not sure what I'm doing wrong).
I have this code that I want to test in my HTML, I copied the HTML in and it looks the same then I made a file in my static folder called edit.js and copied the JavaScript into it (exactly as shown). It didn't work no errors on the page but when I click it nothing happens. I tried to paste a W3 'hello world' code in and that worked but this script does not.
I tried to inspect the code in Chrome and that's where I see the above error (under the resources tab). I can open the js file using Chrome which makes me think the js file is accessible and pointing correctly but I'm not sure how to get it working. I'm using Jinja2 as my template engine to render the HTML and in my header I have:
<script language="JavaScript" type="text/javascript" src="static/edit.js"></script>
and in my main template (the one that gets rendered on all pages) I have:
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
edit.js:
(even putting it within the script tag directly on the page I want to use it on doesn't work)
$('#editvalue').click(function(e){$('#storedvalue').hide();$('#altervalue').show();});
$('#savevalue').click(function(e){
var showNew = $('#changevalue').val();
$('#altervalue').hide();
$('#storedvalue').show();
$('#storedvalue span').text(showNew);
});
HTML:
(it's embedded in a larger page)
<head>
<script language="JavaScript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script language="JavaScript" type="text/javascript" src="static/edit.js"></script>
</head>
... my html code..
<div id="wrapper">
<div id="container">
<div id="storedvalue"><span>Hello</span> [edit]</div>
<div id="altervalue" style="display:none;"><input type="text" name="changevalue" id="changevalue" value="Hello"> [save]</div>
</div>
</div>
I have never been able to successfully run a JavaScript that wasn't on W3 yet. I get the same problem with other scripts even though I see people online saying they work fine for them. Do I need to do anything extra to make this work?
My two questions are:
What am I doing wrong?
Because Javascript seems to just not work when there's a problem, is there a way to get errors or information on what's actually wrong?
I read Uncaught ReferenceError: $ is not defined? and have been trying to figure this out for the last hour and can't see my problem.
First you need to place the jQuery script tag first.
Second, you need to do one of the following things:
Put your code within this function:
$(document).ready(function(){/*CODE HERE*/});
Or like this:
$(function(){
/*CODE HERE*/
});
The DOM needs to be ready before you can use it. Placing your code within anonymous functions that are executed on the ready event of the DOM is how you can do this.
Edit:
$(function(){
$('#editvalue').click(function(e){$('#storedvalue').hide();$('#altervalue').show();});
$('#savevalue').click(function(e){
var showNew = $('#changevalue').val();
$('#altervalue').hide();
$('#storedvalue').show();
$('#storedvalue span').text(showNew);
});
});
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
Script tag for jQuery should come before your custom javascript.
Follow by edit.js
<script type="text/javascript" src="static/edit.js"></script>
Try removing the language attribute..sometimes work for me. It's obsolete now .. i think
You need to include jquery before you can use it.
