Odd Variable Behavior - Changing One Variable Changes Another
Oct 16, 2009
I'm trying to create an array of dates two weeks apart from an arbitrary startDate, and I've noticed some odd behavior in my variables. I did a little experiment on my JS console and here's what I got. My inputs are in blue, the output is in black.
Code:
Everything's good so far, but here's where it gets odd. I try to add 14 days to cur.
Code:
Why is it that when I make changes to cur, the same changes are made to startDate?

My code is pretty simple:
var runUpdate = true;
$.get("FirmMaintServlet?action=checkfirmid&firm_id="+$('#new_firm_id).val(), function(data) {
if(data) {
[Code]......
When this runs, if the first alert shows it is supposed to set runUpdate to false, as you can see. But when the second alert shows it is still equal to true.

I am building a site where I want all links to partial page reload using xmlhttprequest and innerhtml. I have done this before, butI always had to have a seperate xmlhttprequest function for each link. So this time I am trying to write just one function, and have the onClick change which document the request is getting. It is not working and I appear to novice to figure out why. Here is the code, i have bolded some relevant lines:
<script type="text/javascript">
function ChangeContent()
{
var whichPHP;
[Code]....
Also, if I use the innerhtml function to write another of these hrefs, will that link be able to access the function if it is in the header, or should I put the entire function in a .js file on the server? The point of all this would be that the entire page never reloads and all the text content is swapped out on demand.

What's happening: - On pageload the div with id="energytimer" shows the $timer variable - After one second (or more seconds) the amount of seconds is still the same - If I refresh the page the amount of seconds dropped (as should have been) Note: - The PHP is correct (or should be, just needs to be extended) - If I put an alert("test"); in the function timers() it shows every second Am I missing something really important? I posted this here because I thought my problem should be JavaScript related.

I need to change the value of a variable on a <select> question.
Code:
Currently the variable choses either 1or 2 so when I execute the function it will sum the value ie..3,6 ect.
I would like it to add the value in the text part of the option ie.. 5000,10000,15000.
I realize if I could I could change the value to be the same as the text value but the backend of this software needs the values to stay 1 or 2.
I was trying to do an "if else" statement but I am not sure how to format the syntax to work:
Code:

I have a list of most 17 recent entries from a db table and wanna use jquery/ajax to have a next button that loads the next 17 entries when you click it. It passes the 17 variable to the .load which works fine first time around (this is later used as mysql limit), but then I try to increase the start variable with 17 so that next time I click it would pass 34 to the .load (so it loads next 17 again) but this doesn't work, it simply loads same 17 again on 2nd, 3rd ect. click (so nothing changes). use global variables by setting it with var and using it without var inside the function.
<script>
var start = 17;
var loadUrl = '<?php echo site_url('welcome/battles'); ?>';
$("#latestbattlesnext").click(function () {

Is there a way, besides writing another method, to make Date.setMonth() do something more useful than nothing when the month in question creates an invalid date? If I try
d=new Date();
d.setMonth( 1 );
today, I'd really like to get some kind of an error rather than silent failure.

I expect to see "foo" for the 2nd alert. Instead, the value of select is
cleared. Am I missing something?
<html>
<head><title>Foo</title>
<script language="javascript">
<!--
function foo()
{
alert('Before change: ' + document.control.titleFont.value);
document.control.titleFont.value = 'foo'
alert('After change: ' + document.control.titleFont.value);
}
-->
</script>
</head>
<body>
<form name="control" method="POST">
<select name="titleFont">
<option value="sans-serif">Arial</option>
<option value="serif">Times</option>
</select>
<input type="submit" name="control" value="Submit" onclick="return
foo()"/>
</form>
</body>
</html>

I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

Ok, so I've built a member search using ajax to change the results each time a filter is changed. It works great, except one minor issue that I'm struggling with...I just can't specify dynamically in the parent file that linkclass$id opens linkclasscontent$id as I don't know of any way to pass that $id variable back over to the parent.

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

a.) specify two parameters for the changeYear function: today and holiday.
function changeYear(today)(holiday){
b.) in the first line of the above function, use the getFullYear() date method to extract the 4-digit value from the today variable and store the value in a variable named year.
first line
c.) in the second line; use the setFullYear() date method to set the full year of the holiday date object to the value of the year variable.
second line
d.) in the third line, use a conditional operator on the year variable. The test condition is whether the value of the holiday date object is less than the today date object. If it is, this means that the event has already passed in the current year and the value of the year variable should be increased by 1.
third line
e.) in the fourth line of the function, again set the full year value of the holiday date object to the value of the year variable.

I am simply trying to use a global variable in javascript, but can only access the variable on the second call. I can't find anything that relates to this through my searches. My application is supposed to query the server for XML that tells me which years and months are available to put into combo boxes. I want to store this xml in a global variable to access it later.

I start outside of the external JS file by: reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way :)

I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it.I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page.P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side...

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?
