I put the following script on my page so that it would load after everything else and wouldn't slow down my page (I have an api call in the append which is why, but I've let it out for this), but it's still loading with the rest of the page.
<script>
$(window).load(function(){
$('.status').append('result');
});
</script>
As explained in my comment above, $(window).load gets called after all external resources load fully.
If you want to execute a script before everything loads, you may consider the following
<html>
<head>
<script>alert(1)</script>
</head>
<body></body>
</html>

So I made a page that utilizes some javascript and also loads a js file. However, I need to move that code to a template file. When I do so, that script tag and the file are not loaded. And I don't get any error messages during page load in the browser, the file does not exist in browser, and there are no build errors or log messages. Here are snippets of code.
The following works in my "addUser.jsp" file.
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<script type="text/javascript" th:src="#{/resources/js/selectListSort.js}"></script>
</head>
<body>
...
<script th:inline="javascript">
// several event listener loaders
</script>
</body>
But when I move it to my officeAccess.jsp file, it fails to load.
In addUser.jsp, I make the call:
<div th:replace="administration/fragments/officeAccess :: officeAccess ( userForm = ${userForm} )"></div>
All the html in officeAccess is loaded as expected, just the javascript and file fail to load.
From everything I've researched, what I'm trying to do isn't possible.
Since I'm loading the template, the new code is loaded in the body and belong outside the body. Or... they're ignored when loaded via the template engine. I'm not sure which.
In any case, I'll just load the scripts in the parent page as needed for the templates (since this does work).
This is probably super simple answer, but I just can't figure this out.
Basically, I've got a php page only starting with opening <?php tag.
I've got a jquery script that I need to call on this page.
<script type="text/javascript">
$('input[name="_manage_item"]').click(function() {
$('input[name="_item"]')[this.checked ? "show" : "hide"]();
});
</script>
From what I researched, I need to load the script by placing
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
into the <head> tags of the page.
But my page doesn't have the html <head> or <body> tags. Where do I call the script then ?
I tried to place it in front of the opening <?php tag, but that broke the page.
What is the correct way of doing this ?
You can place your javascript outside the php tags at the bottom of you page. But when you use the php in a web page, you should add the html and head and body tags. A simple php page could look like this:
<html>
<head>
<!-- stylesheets and javascript -->
</head>
<body>
<?php
//You php-code
?>
<!-- scripts at the end of the page to let the side load faster -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script type="text/javascript">
$('input[name="_manage_item"]').click(function() {
$('input[name="_item"]')[this.checked ? "show" : "hide"]();
});
</script>
</body>
</html>
Relying on your wordpress tag, I suggest you to read this article. There are described all details concerning javascript usage within wordpress. Probably the most common way is to use wp_register_script() function.
The safe and recommended method of adding JavaScript to a WordPress generated page, and WordPress Theme or Plugin, is by using wp_enqueue_script().
I would also advise you to merge your code to a distinct file, and load it straight after jquery library. It is a good practice, because in such a way browser can cache your script and would not download it on every page request. You should also wrap it into a $( document ).ready() function, to be sure that it will be executed only only when document is in ready state.
I wanted to use the loading page from here http://www.gayadesign.com/diy/queryloader-preload-your-website-in-style/
because the personal website I was making is very poorly optimized and loads quite slowly
The loading page works fine if I make it a seperate page and then redirect to my home page like so:
http://matthewpiatetsky.com/cs103/demo/demo.html
However, I have also tried adding this same animation when I go directly to the page, and it does not work. I think this is because of the other js files present in the document.
http://matthewpiatetsky.com/cs103/
In the redirecting page the script is located here and it works.
http://matthewpiatetsky.com/cs103/demo/js/script.js
In the actual page the script is located here and it doesn't work.
http://matthewpiatetsky.com/cs103/js/matthew.js
The script declarations in the actual page look like this, so this script is called last. Calling it first breaks the page, so I'm guessing the 5-grid js is the problem.
<script src="js/jquery-1.9.1.min.js"></script>
<script src="css/5grid/init.js?use=mobile,desktop"></script>
<script src="js/jquery.formerize-1.1.js"></script>
<script src="js/init.js"></script>
<script src="path/to/file/jquery.queryloader2.js" type="text/javascript"></script>
<script type="text/javascript" src="js/matthew.js"></script>
It looks like you are missing a plugin. Your code tries to use the QueryLoader2 plugin on line 19 of Matthew.js, but you don't have this plugin included on your page.
I currently am working on a large site with many different issues to contend with. One being that I have no easy way to include a script into my <head> without manually doing it for 500+ pages.
I have the possibility to include jQuery.min just inside the <body> tag from an include located there.
My question is, aside it not being a standard implementation, would there be any negative effects from not loading jQuery within the <head> tag? Will all the functions be available?
I am aware that if I do this, I will not be able to call jQuery from within the <head> or before this include... that's okay.
example:
<head>
Standard Head Stuff
</head>
<body>
<div>Some Content</div>
<!-- My Include is roughly here -->
<script type="text/javascript" src="jquery.min.js"></script>
<div>More content</div>
<script type="text/javascript">
$(document).ready(function(){
// Put my jQuery commands here
});
</script>
</body>
The only issue is that a page is loaded from top to bottom and so if you were to place the include statement into the header than you would be assured that the library would be loaded immediately. Otherwise the library may only be loaded at a later time which can cause a delay in some effects potentially.
Head or body, inline code will execute when phrased. Code is generally placed in the head so external libraries can be loaded before the page is (so effects can be run on dom ready). Code in the body will be run once the dom is done with the header code, and done loading page elements (once in the body, elements are loaded from top to bottom). So any code in the body will be executed once the page had loaded (up to that point)
I'm just starting to playing around on a Mac for the first time and I have created a very simple HTML page that uses jQuery to do a simple text swap when an h1 tag is clicked.
When I don't view the page through the webserver and just open it directly in Safari (file:///Applications/xampp/xamppfiles/htdocs/test/mypage.html) it works as expected. However, when I try to view through Apache (http://localhost/test/mypage.html) it doesn't work.
Here's the code:
<html>
<head>
<title>My Awesome Page</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" charset="utf-8">
function sayHello()
{ $('#foo').text('Hi there!');
}
</script>
</head>
<body>
<h1 id="foo" onclick="sayHello()">Click me!</h1>
</body>
</html>
Am I missing something on the Mac? Wouldn't be an Apache setting since its client-side code.. right?
I should probably also mention that I loaded XAMPP to run Apache and MySQL. I have tested Apache to ensure its working using a simple PHP file.

Use Firebug and access the page. One things that might be a culprit is that the web server cannot open jquery.js file because of file permission. Firebug will show if the jquery loaded in page, even you can add the jQuery code on-the-fly in the Console tab.
If you access it using Safari, use Web Inspector and see the if any error showed in Console tab.
One last thing, make a habit to avoid onclick, do this instead:
<script type="text/javascript" charset="utf-8">
function sayHello()
{
$('#foo').text('Hi there!');
}
//wait DOM loaded
jQuery(function($){
$('#foo').click(function(){
sayHello();
});
});
</script>
Also, it's better to put the js code near the page end, before </body>, so it would not block concurrent page element's loading.
