Comparing Multiple AND And OR Statements?
Mar 5, 2009
I need to test the contents of three fields to validate which contain text, and based on the results, set additional variables. I'm sure this is falling off the log simple, and I got it to work in PHP, but am having problems getting the syntax correct in Javascript.
In a nutshell, if a front AND a rear msg is entered, the price is $115, else the price is $80. I'm sure there's an easier way to code this than what I've done, but I don't know how to correctly perform several && and || in the same comparison.
Here's the PHP...
function notEmpty(){
var FrontMsgTxtTop = document.getElementById('FrontMsgTxtTop').value;
var FrontMsgTxtBottom = document.getElementById('FrontMsgTxtBottom').value;
var RearMsgTxt = document.getElementById('RearMsgTxt').value;
[Code]....

This is what i'm working with now but can only get one function to validate. This is the script I have so far. With credit going to pmw57 Need to be able to validate more than just one function.
<script language="javascript" type="text/javascript">
var form = document.getElementById('healthwiseorder');
form.onsubmit = validateForm;
function validateForm() {
[Code]....

I am currently using a function to validate a form on the client side
(see code below). At the end of the function, I would like it to also
compare a startDate against an endDate to ensure that the endDate is
greater than (comes after) the startDate. The date format I'm using is
MM/DD/YYYY and it's writing to an MS SQL Server 2000 database table
via ASP. Code:

I have two strings that I need to compare and modify when there is a
matching value in the two. If strA = ??,' then I need to remove
the value ??,' from strB and the new value would be strB =
??,12935'
strA = ??,'
strB = ??,12937,12935' (these could be any values in any order)
I'm not sure where to begin on this.

I need to check if two hashes are identical.
My thoughts are something like this:
function compareHash(hash1,hash2){
if(hash1.length != hash2.length){return false}
for(var key in hash1){
if(hash1[key] != hash2[key]) return false;
}
return true;
}
Have I missed something, or is there a more direct approach?

I'm having trouble comparing 2 input boxes, using getElementById.
I have 81 hidden inputs (id's b0 through b80) and 81 input boxes (id's a0-a80). (Its just sudoku, so theres no security threat with them being viewable in the source)
I'm using this code (ill worry about the for loop later)
var solved = true;
if(document.getElementById(a0).value != document.getElementById(b0).value) {
solved = false
alert("not solved"); // debug
}
But it doesnt seem to be working. Im getting the error a0 is not defined. I know for sure that I have an input box with id=a0.

I am sure if I searched long enough I could find the answer, but to save time I would appreciate help with the # statements, such as #include, #csstopmenu, etc which I find in the scripts here and elsewhere. I know that #include is used with shtml to include another html page. What are the others? Is there a definitive list, and if so where can I find it?

I have the following script
function timeDifference(laterdate,earlierdate) {
var difference = laterdate.getTime() - earlierdate.getTime();
var daysDifference = Math.floor(difference/1000/60/60/24);
difference -= daysDifference*1000*60*60*24
document.write('difference = ' + daysDifference + ' day/s ');
}
var laterdate = ?;
var earlierdate = ?;
timeDifference(laterdate,earlierdate);
//--></script>
And would like to insert my datein and dateout values where the ? marks are above in red. I can call these variables into the form on the page using <%=Request("datein")%> but how do I call a variable into the script above?

I am developing a battleship game in javascript. I created a table of grid squares pictures. In the tags in included onclick = "a specific method to place a ship(this.id). This is not working. I am wondering if there is an easier way to pass an id through a parameter or would I have to do something different?

I apologise for any complexity of the following script, but what I am trying to achieve is
1.) At 6:51 am, the image sunrise.png is written as the background of #wrap
2.) At 12:04 midnight through 12:07 midnight, the background of #wrap is green.png then
3.) Then, at a random time at night that is not 6:51 am nor in-between 12:04 midnight & 12:07 midnight, the background of #wrap is set as aurora.png
This is the code of if statments that I wrote to achieve it:

I have this function which works great in Firefox, but doesn't work in IE. I can make it work in IE by breaking it in Firefox, but I'd like it to work in both.
Here's the function, with associated code:
function validate_check(input, message)
{
var par = input.parentNode;
var prev = input.previousSibling;
if(!input.checked) {
if(prev.innerHTML != message) {
var errmsg = document.createElement("p");
errmsg.innerHTML = message;
par.insertBefore(errmsg, input);
}
dosubmit = false;
} else if(prev.innerHTML == message) {
par.removeChild(prev);
}}
var agree = document.getElementById('agree');
var agreemsg = 'Please make sure you agree to our <a href="/tou.php" target="_blank">Terms of Use</a> and <a href="/privacy.php" target="_blank">Privacy Policy</a> to add your listing.'
validate_check(agree, agreemsg);
For the two attributes the function accepts, input is a node from that document tree that is a checkbox, and message is a string.
If the checkbox is not checked the function inserts a <p> element immediately before the input. That part works fine in both. However, the 'prev.innerHTML == message' and 'prev.innerHTML != message' don't work properly in IE. I think it is because of the <a> tags in 'message'. However, when I try to use the String() function there are problems because the 'prev' object is not always set, (like, if a paragraph isn't written right before the checkbox).

I want to put a form on my site where the user can enter some information, but I don't want the user to enter the same information twice over the couple of fields that I have.
Is there a javascript that can help to validate the form information or some other way? And if so, is it easy to do?

So I have some code like:
if (document.Insurance.State.selectedIndex == 1)
{
ifIll();
}
else if (document.Insurance.State.selectedIndex == 2)
{
elseKan();
}
else if (document.Insurance.State.selectedIndex == 3)
{
elseInd();
}
I am trying to replace the if-else statements with case statement as
follows:
var index = document.Insurance.State.selectedIndex;
switch (index)
{
case 1:
ifIll()
break
case 2:
elseKan()
break
case 3: elseInd()
break
}
This code doesn't work ! Am I missing something here?

<script language="javascript">
<!--
self.location.href='#add'
document.addform.txtTitle.focus();
//-->
</script>
the self.location.href='#add' goes to a html anchor on the page, and the focus is supposed to set the cursor inside the first textbox when the statement is run.
if i run it as is, it will go to the anchor like its supposed to, but won't put the cursor in the textbox. if i comment out the first statement, it will put the focus on the textbox.

I have a very simple script that generates a prompt window. Instead of using a default text, I have left the text field empty. However, I would like a default message to display in the pop up window if the user does not enter a value in the prompt box before clicking okay. I tried adding a conditional statement but the default text does not write in the pop up window.
Here is the code:
Code:
function promptBox(){
var message = prompt("Who is your favorite Hollywood Star?", "");
newWindow = window.open('','','width=800,height=600');
newWindow.document.write(message);
newWindow.focus();
if ((prompt) == null);
document.write("No Value Entered");
}

I try to figure out how I can merge two onclick in one: The one is opening a "lightbox" div with a fullsize view. Now I would like to count this click with loading a site in an iframe. I am not that known in javascript, therefore my question: Is it possible?
This would load the iframe:
PHP Code:
onclick=parent.fullsize.location='[URL]';
This is the onclick statement in the lightbox.js:
PHP Code:
anchor.onclick=self._genOpener(num)}var body=d.getElementsByTagName("body")[0];
Separated the both onclick are not working. How I can put them together in one onclick? I tried this, but it is not working:
PHP Code:
anchor.onclick=self._genOpener(num)}var body=d.getElementsByTagName("body")[0] && parent.fullsize.location='[URL]';

I have a pair of dates in a form that are made up of 3 text fields per date. The day and month fields are 2 digit, the year is 4 digit.
startday
startmonth
startyear
endday
endmonth
endyear
I can't easily change this for a number of reasons. I know the values themselves will be valid (they're generated by a calendar selection script) but I want to check the date created by the end variables is not before the start date. Any script to build a date from the 3 fields for each, and return false if the end date is earlier than the start date?

I have 2 fields in a form, field1 is type hidden while field2 is type text.Both will have numbers in them. I need to compare these 2 in my form validation and having issues getting it to work right. If I do something similar to the following:if ((passForm.field1.value) < (passForm.field2.value) ) {alert.....It runs, but is running the validation, but is reading the values as text and literally left to right.
so for example
If field1 = 12 and field2=3 it does not run the alert (wrong)
If field1 = 12 and field2=100 it runs the alert (wrong)

The jQuery isn't working when calling elements placed in conditional statements. My sample code is shown below. This code works beautiful if the if/else conditions aren't there. What is the problem? Is there something wrong with my code? Is there a workaround? I absolutely need to use a conditional statement in my production code.
<?php
$test = 'true';
