Unable To Access Javascript Function On <body> From <head>

Jul 23, 2005

in the body tag, I have this code (just to test):

<script LANGUAGE="javascript">
<!--
function hiThere() {
alert("hi");
return true;
}
//-->
</script>

in the head section, I have this code:

<script LANGUAGE="javascript">
<!--
document.body.onload=hiThere();
//-->
</script>

By the way, I know someone will comment, by "does not work, I mean on
the load of the page, the alert is not displayed, nor are any errors.
Thanks for any help you can offer.

Injecting Local Variable To A Function

Nov 17, 2006

I'm looking for a way to define a function that's only effective inside
specified function.

Featurewise, here's what I want to do:

bar_plugin_func = function() { ...; setTimeout(...); ... };
wrap_func(bar_plugin_func);
bar_plugin_func(); // calls custom "setTimeout"

So while plugin developer thinks s/he's calling top-level function,
I want to hook it by somehow injecting local variable with the same
name.

Simply doing something like

;(function() { setTimeout = function() { ...my custom implementation
})();

is not ideal, as that'll taint global scope. Actually, I can live with
that for now,
but it's my technical interest to find a way to define it locally.

JQuery :: How To Modify Local Variable Of Ready Function

Dec 11, 2011

I want to modify a local variable of the ready function set like so:
$(function () {
var modifyme = 0;
...
});
I cant change the code setting the ready function, as I am writing only a greasemonkey userscript. I already tried using the .data("events") method, but it never listed the "ready" event. Any function so I can modify the variable!

Script Working In <body> But Not <head>

Aug 1, 2011

I can get Scripts to work fine in the <body> but not all scripts seem to work in the <head>

For example, this works fine:

<html>
<body>
<p id="date"></p>

[Code]....

It could just be that I broke one of the fundamental laws of coding that I don't know or something but like I said, I've only just started JavaScript. Also, the tutorial I have isn't to clear on the differences between using the <head> or the <body>. Just kinda says you can do both.

I'd like to use the <head> wherever possible because it would be so much neater to keep all the JavaScript in one place and all the HTML in another. Pretty much like you can do with CSS.

Placing Scripts In HEAD Or BODY For Best Performance?

Jun 9, 2009

This questions mainly regards using google's analytics code on some of our websites. We currently place the code at the footer as it can hinder load times if placed further up in the page.

For this, or in general use, is placing javascript in the BODY or HEAD better for one or the other as far as load times? Can placing scripts in one or the other allow the page to load concurrently with the script and not sequentially?

JQuery :: Script Works Fine When In The Body Of My HTML - But Not In The Head ?

Aug 21, 2011

I've written a jQuery script for a crossfade slide show. My script works fine when I put it it the body section of my HTML. But when I move it to the head, the script no longer works. The div where the images are supposed to appear remains blank. Does this matter? Does this mean that there's a flaw in my script? Should I be worried? Or should I simply leave the script where it is in the body section.

Here's the crossfade slideshow script:

Getting A Variable To Pass In A Function Parameter?

May 27, 2009

I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?

I am using PHP:

JQuery :: Pass A Variable As An Integer To A Function?

May 16, 2010

Let's say I have this function: function add(x, y) { var add = x + y;

[Code]...

So let's say the value of select_first is "1", and value of select_second is also "1". But when they are passed to the add function, the returned value is 11 and not 2. So what I understood is that it took the values as strings instead of integers. What should I do so that select_first and select_second are integers instead of string?

JQuery :: Pass A Dynamic Variable To Function?

May 15, 2009

I have a bit of php that creates an entry on a page for each row in a table, some pages may have multiple entries, others just one.

eg.

<h2 class="title">{title}</h2>
{summary}
<p onclick="openBox({entry_id})">Click to read more ></p>
<div id="{entry_id}" style="display:hidden;">{body}</div>

I would like to have just one function to open and close all individually, eg.

$(document).ready(function(){
function openBox(id){
if ($("#id:first").is(":hidden")) {

[Code].....

Well I know I'm doing something wrong as this is not working, and I don't know how better to explain I hope this is sufficient, I'm not worrried about the php/html bit as that is working fine.

Pass A PHP Variable To A Window.onload Event Function?

Dec 21, 2009

How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

Writing HTML In The <head></head> Of A Page With JS?

Dec 16, 2011

I know this can be done with media-queries in CSS3, After attaching the jQuery library, I used js to get the width of the window browser-viewport) and store that in a variable.

What I was aiming to do was write a <title></title> for the page and attach a stylesheet through <link /> using js only when the window's height was greater than 596px. So, I wrote the following:

Code HTML4Strict:
<!Doctype HTML>
<html lang="en">
<head>
<script type="text/javascript" src="../assets/js/jquery-1.5.1.min.js"></script>

[Code]....
