[Javascript Redirect...]

put this in the head section (or anywhere you want)

<script language="javascript">
history.go(-1);
</script>

[setTimeout and variables!!]

You'll lose the function scope in setTimeout, you can use global variables or the variable value.

 

e.g.

setTimeout("okaythen('" + trID + "')",2000); 

Notice the single quote ' before the " + to make the value as a string

[createElement]

div1.className = "class1"; works in any grade A browser

[add image src from javascript function]

if mySecondVar is a string, use document.getElementById(mySecondVar).src = "...";

[Getting errors whith numbers]

Yep,

 

alert(parseInt("08")); // alerts 0

 

alert(parseInt("08", 10)); // alerts 8

[cloneNode()]

You can just assign a different id after you clone the object

 

p = document.getElementById("para1"); 
p_prime = p.cloneNode(true);

p_prime.id = "my_new_id";

[PHP Code from MYSQL database]

remove the <?php and ?> from the string and use eval function

eval('some php code here');

 

[Frames or no frames? that is the question.]

Some ajax may help. Simply when the page load attach an event to all the links and make them fetch the page content using AJAX. If the JS breaks, the link still points to the page, you can also add a special query to the URL as an ajax (i.e. var url  = a.href + "?ajax=1"

[javascript hover link description]

make sure you call teh JS after the page has loaded (onload event)

[a basic question (remove the yellow bar)]

If you open a page with JS locally (on your computer, not online), it'll always show the yellow bar

[Very basic Alphabete Selector]

You can modify the previous script to output a javascript array from php and use that array to loop through the elements

function toggle_alpha(target) {
    var divs = ['A','B','C','Color','D','F','K','L','P','Q','R','S','Z']; // use php to output this array
    for (i=0; i<divs.length; i++)
        document.getElementById('Searchstring_'+divs[i]).style.display = "none";

    document.getElementById(target).style.display = "inline";
}

 

You can detch the document.all since IE support document.getElementById()

 

Also, you can make a JS object that will update the HTML of the div based on the user click

<script type="text/javascript">
var cont = {};
cont.A = 'this is a'; // use PHP to output these lines
cont.B = 'this is b';
cont.Color = 'this is color';

function update_div(val){
    document.getElementById('div_id').innerHTML = cont[val];
}
</script>
<div id="div_id"></div>

[JS Form Validation help]

Try to search this form on how to validate numbers (or search google) most likely you'll find a regular expression (something like value.match(/^\d+$/))

 

Try to browse your site using firefox and after you get the error, click on "Tools" (next to File, Edit, View) and select "Error Console" This will help you find the bugs you have.

 

I always use document.getElementById() for anything, for the select menu, try to get the option value

 

document.AddProduct.ItemType.options[document.AddProduct.ItemType.selectedIndex].value

 

and see if that's work.

[JS Form Validation help]

You only can access form fields by document.form.field, other elements you'll need to use document.getElementById('ID')

 

In your code, you'll need to change

document.mySpan5.innerHTML (or 1, 2,3,4,etc...)

 

to

 

document.getElementById('mySpan5').innerrHTML

 

Hope this helps.

[javascript hover link description]

you can try to add it the event from a script

 

<script type="text/javascript">
document.getElementById('about').onmouseover = function(){
     document.getElementById('description').innerHTML = "whatever";
};
</script>

[Very basic Alphabete Selector]

Something like this

function toggle_alpha(target) {
    var alphabits = "ABCDEF....Z"; // just fillin the blanks
    for (i=0; i<alphabits.length; i++)
        document.getElementById('Searchstring_'+alphabits.charAt(i)).style.display = "none";
    document.getElementById(target).style.display = "inline";
}

[document.onmouseclick??]

okay, I just tested with document.onclick and it looks like it's working. Here is an example

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<script language="javascript">
	document.onclick = function(){
		alert('here');
	}
</script>
</head>

JavaScript/ActiveX can't convert video when uploading, you'll need to convert it before or after.

[Hey]

make sure your select options have values

<option value="Video">Video</option>

[AJAX load external html into div]

Your second request override your first request. Your req variable must be a local variable in the function, try to add a var infront of it

if (window.XMLHttpRequest) {
    var req = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
    var req = new ActiveXObject("Microsoft.XMLHTTP");
}

 

hope that's work.

[username validation?]

first make sure you have an id in the input field and it's uniq ( id="username" ), if it's still not working, you can post your code or URL and I can take a quick look

[document.onmouseclick??]

try document.body.onclick

[Working in IE, but not FireFox...any ideas???]

For accessibility point of view, bronzemonkey is correct. Personally, if the user's browser doesn't support JS, they should either update their browser or enable JS to browse my site (if I am losing 5% because of JS is not enabled, oh well). Using a simple CSS style to make the tr looks clickable "such as cursor:pointer" will solve any display questions for the user. But the final discussion is for the website owner and how does s/he wants the user to interact with their site.

[Document Write]

it's because you're using curly quote marks in the script tag <script language=”javascript”>

 

You should use normal quote marks "

 

If you copied an example for MS Word or a website, make sure all the quote marks are " and not ”
