Comparing Strings And InnerHTML Results In IE

Jun 4, 2006

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).

Comparing Strings

Apr 16, 2007

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 am using javascript to compare two strings. it works well with normal strings. but when the strings contain "&" (e.g. & #1234; *no space), it does not work well.

code:
q = document.getElementById("q").value;
a = document.getElementById("a").value;
if (q == a)
document.formName.all("check").innerText = "correct";
else
document.formName.all("check").innerText = "wrong";

InnerHTML / DIV Size Changing To Various Strings

Dec 21, 2010

I was playing around with some onmouseover/onmouseout and setting innerHTML to various strings depending on what has been mousedover/out. The DIV for the innerHTML was above the items being onmouseovered/out and because the strings sent were of different lengths, sometimes a one or two line wrap would happen and everything below it would be resized accordingly creating a horrible effect. For reference, what is a good way to approach building pages which are immune to this effect?

Function - Compares Two Strings And Then Shows Or Hides A Div Depending On Results Of Comparison

Oct 8, 2011

I have been on this for over an hours now, it is probably something simple and/or stupid, but why doesn't this script work? I have read forums til my eyes are crossed and can't see what I am doing wrong I am new to javascript, but not programming. The point here is to create a function that compares two strings and then shows or hides a div depending on the results of the comparison. I was trying to pass in the name of the two input text boxes containing the text and the name of the div to show or hide (so that it can be used in multiple scenariios.) Right now my error message is that document.getElementById(field1).value is not a function.

Here is the code below..

Undefined Results For A GetElementByID InnerHTML Function?

Jan 27, 2009

Here's the problem: I have several hidden divs containing information. When you click on a link, javascript executes which is supposed to move the appropriate info from one of the hidden divs into the visible 'body' div. The javascript isn't working, though, and I'm getting 'undefined' instead

Strings Not Replacing Strings

Sep 25, 2007

I've been learning javascript for about a week and I'm really struggling right now. This is a homework assignment to help in learning loops and arrays.

What I want to happen is when a form button is hit it will replace the array from the one previous instead of just adding to it. Hopefully that makes sense. What do I need to do? here's my code....

Comparing Two Dates

Jul 23, 2005

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:

Comparing Two Hashes

Jul 20, 2005

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?

Comparing 2 Input's

Dec 5, 2006

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.

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]....

Comparing Two Dates - In And Out Values

Dec 9, 2009

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?

Calendar Selection - Comparing Two Dates For Validity

Sep 14, 2011

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?

Form Validation Comparing 2 Field Values?

Mar 4, 2010

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)

Removing Case Sensitive When Comparing Form Fields?

Jun 20, 2011

I'm trying to make my form both check that the e-mail's match and also be case insensitive when being submitted. I've figured out how to get the e-mail's to be checked to match, but can't figure out how to also make it not case sensitive.

This is what I have so far...

<head>
<script type = "text/javascript">
function checkSame() {
var emval1 = document.cform.email.value;

Comparing Image Id's In Order To Change Opacity OnClick

Mar 9, 2010

I am using the following function in order to change an image opacity on a mouseover and mouseout. This function works fine but does not handle a onClick. What I mean by this is...... How can I create/alter the function to handle an onclick? I want to be able to click on an image (one of many) and have that image opacity change to 50%. There are other similar images whose opacity would need to remain at 100%. If one of those are clicked, that images opacity would then change, and the previous would restore to original value of 100% I thought about passing the clicked images id to the function but I can't find a way to compare an image id VS a passed image id.

Strings And Numbers...?

Feb 3, 2006

I'm having difficulties arithmetically manipulating form element values.

I've entered data into the form, and I fetch them using a js, as:

p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);

Then I add these as follows:

scoreLeft = Number(scoreLeft + p&Left + ...... +);

This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?

Strings As Arrays

Mar 6, 2007

Safari and FF seem to allow this:

var wiggy = "ABCD";

ch = wiggy[2]; // ch will contain the character 'C'

however my JS book seems to insist that I do this:

ch = wiggy.charAt(2);

and indeed doesn't appear to mention the first method at all.

Since for my particular purpose I want to treat the string as an array
of single characters, I prefer the first method rather than the second.
Is there any reason not to pursue this approach?
