i accidentally set up my path variable instead of classpath and now my
computer can't find any of the executable files. it would be great if
anyone knew what really should stand by the path variable. i don't
suppose there's something like 'set all to default?
I need help in access the Username/Domain environment variable from javascript.
Could someone tell me how to get the contents of this variable?
I am moving from a development environment to a production environment and would like to know the best way to handle javascript/jquery files on the production server. I have looked at Packer and also searched this forum for ideas but the only threads I came up with were a year old and I would prefer some comments more recent than that I think.
Obviously I would at the very least like to strip out comments, etc. and would also like to minimize them as much as possible if that makes a performance difference. Any input is welcome at this point.
Just wondering if anyone has any ideas on how to solve a particular
problem. A client wants to print barcode labels from their (web/php
based application). The barcode labels are very small, so I'm guessing
that doing a screendump via a standard inkjet isn't going to work
(i.e. might need somehow to print to a barcode printer!)
Any ideas where to start?
I am extremely frustrated with my current setup developing jquery as I am in Dreamweaver. I've installed the add ons but they dont help enough. My biggest beef is with something that auto-indents to make the structure of the code legible. That and decent colouring. Can anyone recommend something that does all that and potentially even reloads the page on save....and previews in browser...and debugs?
View 11 Replies View RelatedI have a page that's built using ASP.NET and using a master page.Page contents shows up for a moment then I get a blank page - when I run it. If I remove the jQuery code from my page - then I get the contents.
I tried putting the following in the master page.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" >
</script>
if I put the line:
var T = new Array(-1);
anywhere in my script, it stops working. e.g
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
var T = new Array(-1);
document.open();
document.write('hahahah');
-->
</SCRIPT>
doesn't produce any output. If I change
var T = new Array(-1);
into
var T = new Array(1);
or
var T = new Array(-1,-1);
everything works fine again.
Same results in Mozilla 1.7.2 as in IE 6.
Is that a bug in both their javascript interpreters or can anybody
give me a good explanation of why that is?

This function is intended to make visible a row, just one by each time the function is called. the way im invoking "(row)" is wrong, i think...
I'm trying to make my timeclock for work, and the Date object in Javascript is giving me wrong values. I made sure that the time on my computer is the actual time, day and year, yet I either get dates that are 2 week in the future, or set in the year 2403. I have no idea what's going on, even if I just alert out a new Date() with no variables, I get the same result. If there is something that I'm not declaring or anything, I'd love to hear what it is.

I have a form with an onsubmit event handler:
<form id="uploadForm" method="post" action="..."
onSubmit="checkDates()">
The event handler does some minor validation, then returns true or
false:
function checkDates(y, m, d) {
if (endDate.getTime() >= startDate.getTime())
return true;
alert("Start date must precede end date");
return false;
}
(The arguments to the function are used when it is called elsewhere,
not as onsubmit.)
I also have a library class which needs to process the form submit, so
it hooks onsubmit like this:
MyClass.setOnSubmit = function(listId) {
var list = document.getElementById(listId);
var form = list.form;
var f = form.onsubmit;
if (typeof f == "function") {
form.oldOnSubmit = f;
form.onsubmit = function(){
var ok = this.oldOnSubmit();
if (ok)
return MyClass.onsubmit(listId);
else
return false;
};
}
else
form.onsubmit = function(){MyClass.onsubmit(listId);};
}
My problem is that the value returned from oldOnSubmit and stored in ok
appears as 'void'. This happens in IE 6 and in FireFox 1.07. Can anyone
explain what's happening?
I got this (piece of) script from 'DHTML Utopia - Modern Webdesign - Using Javascript & DOM'.
function aKeyWasPressed(e) {
if (window.event) {
var key = window.event.keyCode;
} else {
var key = e.keyCode;
}
alert('You pressed the key: ' + String.fromCharCode(key));
}
It is example of adding an eventlistener to a textarea. The events works alright, but when I press 'a' the alert gives me 'A', when I press Ǝ' I get 'h', when I press Ɔ' I get ''', when I press 'ŕ' I get Ɔ', .... Has probably something to do with the fact that I don't live in the UK or
USA. But it shouldn't matter; a key is a key.
What do you think about emulating private variables for a class this
way?
function Something() {
var private;
Something.prototype.getPrivate = function() { return private; }
Something.prototype.setPrivate = function(newPrivate) { private =
newPrivate; }
}
var some = new Something("My private");
alert(some.getPrivate());
alert(some.setPrivate("Nyah nyah"));
alert(some.getPrivate());
That way the accessor methods instances are shared among instances of
Something. What do you think?
I have a function for totalling decimal values provided in textboxes
that form a column on a webpage. This script should total the values
in the textboxes, displaying the result in the final
'optotalprogtime' text box formatted as a decimal.
Here is what I've got so far, but I'm getting annoying "object
expected" errors on the line where I attempt to format the number (as
indicated by the comment below)
//realtime calculation formating as minutes (decimals)
function opprogtotalcol() {
alert("in opprogtotalcol");
document.getElementById('optotalprogtime').value = 0;
for (var rowNumber =1; rowNumber <= 12; rowNumber++){
document.getElementById('optotalprogtime').value =
parseFloat(document.getElementById('optotalprogtim e').value) +
parseFloat(document.getElementById('opprogmin' + rowNumber ).value);
}
if(!isNaN(document.getElementById('optotalprogtime ').value)){
//only works for numbers
document.getElementById('optotalprogtime').value =
formatNumber(document.getElementById('optotalprogt ime').value,
2);//format number here
}
}
Any insight would be appreciated.
To head off concerns about wrapping code correctly, my code is

I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?
function wait(time) {
while(1){
setTimeout("break;",time);
}
}
function wait(time) {
var flag=0;
while(flag=0){
setTimeout("flag=1;",time);
}
}
I am new to jQuery and I am reading this book as an introduction. I find it very good, but I came across an example today that doesn't make sense to me. It is an example of the prev() method and is like this:
$("h1").prev() // Sibling elements of <h1> tags
Is this correct? I thought prev() just picked one element so it should be "element" instead of "elements" in the comment. Alsoa sibling of <h1> tags would have to be another <h1> tag wouldn't it? And there are no <h1> tag before all <h1> tags?
So im basically using a link, to scroll through a series of divs to select the correct one.Ie click on happy, and scrolls to 'happy' div, However, the scroll seems to not go to what its linked to, but scrolls to the third div in the list.

I have this script:
<SCRIPT language="JavaScript">

The problem? On a computer with 1280x1024 resolution, IE detects it to be 1024 (thus sending the user to the wrong page). It works perfectly in all other browsers (that I have tried).
I am using the same java script to help add shipping costs for paypal in my html.I have worked very long and hard to get to this point.I have saved and named each java script for it's form.However, when there are more then one on the html page it always calculates the last form giving me the wrong price per quantity on the first.I have not found a way to differentiate or id and separate.

This is quite mysterious. I have several list items like this:
HTML Code:
<li>Private</li>
I am looping through them all trying to get the text inside each list item for a comparison with a string from elsewhere.
Javascript Code:
var coresubmenu = document.getElementById('core').getElementsByTagName('li');for (var i = 0; i < coresubmenu.length; i++) { coresubmenu[i].onclick = function() { if (this.firstChild.nodeValue == 'Private') { // fail } alert(this.firstChild.nodeValue.length); // alerts 8 }}
IE alerts one more than the actual length in all cases. Google hasn't brought anything up for me on this one - any ideas?

I'm trying to build a slideshow for wordpress. On a static page everything works as expected.In Wordpress however, the same script*1* behaves differently. The activeSlide is hidden behind the "default anchor image". I think it's because activeSlide gets assigned to li instead of the a -tag. You can see that with Google Chrome. The activeSlide class is advancing, it's just assigned to the wrong element. I'd like to target the link (a) again, so the green box appears in front of the red box.
This is the script
<script type="text/javascript">
$(function() {
$('#slideshow').after('<div id="slide_navi">').cycle({
fx: 'scrollLeft',
speed: 600,
Timeout: 4500,
activePagerClass: 'activeSlide',
pager: '#slide_navi',
pagerAnchorBuilder: function(idx, slide) {
return '<li><a href="#"><img src="images/transparent.png" /></a></li>';
}});
});
</script>
The only difference is the way I get the images. But this shouldn't change the activePagerClass target, right?
I set up a function in JQuery to do .load() to a DIV. (This function appears to work only in IE.) This works fine if I am loading an html document to the DIV, but if I load a .pdf file, it looks like it doesn't use the right mime type for interpretation. It looks like it just streams the binary code into the div. Is there a way use JQuery to load a PDF file into a DIV and have it render correctly?
