InnerHTML String Compare Not Working?
Jan 22, 2011
why the string comparison test doesn't work in this javascript function? It works if you use just text between the currentItem div tags, but not when you use html for an image. I even tried to use iso characters instead of angle brackets, as in "<img src=expand.png></img>" and still no dice. Why not?
Is it because of the way innerHTML manages html and it's not really a string? Is it because it doesn't have all the tags and some other representation?
Code:
<html>
<head></head>
<body>

I need some advice regarding wrote a javascript function.
The function purpose is to check the variable "selectedSeat",
for e.g if the selectedSeat value is
var selectedSeat = "A:01|A:03|A:05|B:01|B:02|B:03";
var selectedArray = selectedSeat.split("|");
because row A is not in sequence , i will display alert box to
user,but row B is in sequence is ok.
Main purpose of function is check if the row is in the sequence.
I have been cracking my head about this , anyone have suggestion is
much appreciated.

if (123 > 33) will return true
and
if ("123" > 33) will return true
So my question is, if the above behaviors are the same?? If string is
a number, and compare with another number, it will be the same behavior as compare 2 numbers?
In this case, it is comparing 2 strings that are numbers, so they are
string comparisons here. correct?
if ("123" > "33") will return true
In this case, "33a" is not a number, that's why when it compare with
another number, it always return false. correct?
if ("33a" > 33) will return false...

I'm still pretty new to javascript and dom, but have been coding with other languages for a while.When I try to compare a string to a .nodeValue it always fails, even if they are same. From what I've read typecasting is automatic in javascript or is this incorrect? For instance
var myGreet = "Hello";
var myFrag = myXML.lastChild.firstChild.firstChild.childNodes[0].nodeValue; returns Hello
if(myGreet == myFrag){ always returns false
alert(myFrag);
}

I have been working on a script that can be placed on any of our clients websites. It is a mix of PHP and Javascript.it calls the php script on my server which takes their request, processes it and provides a file ready to be read on my server. This file will be in multiple formats depending on how we have confirmed with the customer so it could be xml , html, csv etc.The problem I am having is that I have used PHP's file_ get_contents function to obtain the html of the file this script creates however when i try to write the contents out to the screen using javascript I get errors.Has anyone ever come across this issue and does anyone have any advice on how to actually take the contents of the file (stored on an external website) and displaying it?

I can't imagine that IE 8 wouldn't support innerHTML but for the following code:
HTML Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
[Code]....
What did I do that IE 8 doesn't like?

I have a textbox in which users can enter some text. And after entering this text I show it for them with help of innerHTML. ( befor it - I replace smiles with <img> tag ) I'v tried to enter some JavaScript there, and have found that it is not working. The question is how safe is that?

when i click a button, this codes will be executed (tested, its working)
var cart=document.getElementById('cart');
cart.innerHTML=cart.innerHTML + document.getElementById('name'+cartNum).innerHTML + "(" + qty + ")" + "<br>";
this is the style of my cart
[Code]...
my problem is, the overflow which i set to auto is not working. the div keeps on enlarging its height everytime i click the button. seems like it has a conflict with innerhtml?

I'm having an issue with Firefox and the innerHTML code. My index file has the following html body code in it:
Code:
<div id="testBox" style="text-align: center; color:white;">
test text
</div>
Then, in a separate html document loaded through an iframe, I have the following code that works great in IE but not in Firefox:
Code:
<SCRIPT type="text/javascript">
function ChangeML(){
parent.testBox.innerHTML ='text has been changed';
};
</script>
The function ChangeML is called on a click event using MooTools, but I figured that part isn't what's causing the problems because everything else works fine. No error seems to be reported ... it just skips right over this piece of code.

I have a form that is shown depending on some criteria. If the criteria are met, I use innerHTML to swap it in. When a button is pressed, the info on the form is checked with javascript - if it passes the check I use innerHTML again to change the button to '...'.
This works fine on Firefox and Safari - the problem is that it doesn't work when I test it with my iPad (iOS 4.3). The button stays the exact same and the javascript seems to stall on the line where I execute the innerHTML. Up to this point, innerHTML on mobile Safari seemed to work the exact same way as MacOS Safari. On my iPad, the innerHTML swaps out this button if the event is triggered from a different button, but not from id="submitbutton" itself.I tested another method - disabling the button. Same issue - works on MacOS Safari/Firefox but not on mobile Safari on my iPad when using onClick from itself.

I got this page: [URL]
I got this PHP script which generates a javascript array of filenames. Everything works fine when I add DIRNAME to the array strings in PHP, but if I want to concatenate the strings in this for loop, it gets weird.
I've tried alert() both arrays when they are the same, and there is no difference there, however when the array of files (fadeimages) is supposed to get loaded into the slideshow it doesn't get displayed.
When I look it from the Google Chrome Inspect element, the image src is the url and /i. That's the begging of the path name, but why only the first letter?

i used the String.length(string) function in javascript to get the length of string but nothing happened. It doesn't give me a value when i tried to view the result using an alert function. Actually, this kind of problem does not only exist with the length function, it's also the same with the trim(). I have not tried using other functions but perhaps it won't also work. What could be the possible reason for this?

Trying to validate a name... If it's in the database, return "exists" if it isn't return "newOne". I get "exists" or "newOne" back in my success function and set a variable (var ifExists) with that text, but when I try to do something based on whether ifExists = "newOne" or "exists", it always goes into the first part of the function...
jQuery:
var sendMenuName = "menuname="+menuname;
$.ajax({

I've added the most basic implementation of JQuery tabs. It's working fine so long as there's not a url-friendly query string.In other words, if I load index.php, it will work fine. Even index.php/anystring doesn't have any problems. However, if I try to load something such index.php/anystring1/anystring2, none of the CSS styles for the tabs appear to be applied to the tabs list making all the tabs' contents appear on the same page.how I can work around this to ensure I can preserve the current format of query string without breaking the tabs? Using the old fashioned way doesn't appear to result in any problems, but I'm trying to avoid having to revert to that format.

I want to obtain the user's current age by comparing their date of birth
(user inputs) to the current date.
I know how to get the Current Date but I'm not finding how to calculate the
Current Date minus the User's Birthday.
It would be something like yourage = curdate - bday;
I will then use the results to determine if the User is Over 21 or Under 21.
I'm going nuts trying to figure this out.
Is there an Easier Book to learn this stuff other than the "Begining
JavaScript 2nd Edition". Code:

A HTML Form has 2 sets of 3 dropdown select lists. The 1st set is for users to enter the start time & the 2nd set is for users to enter the end time. The 1st dropdown select list in both the sets is where users will select hours, the 2nd dropdown select list in both the sets is where users will select minutes (the 2nd dropdown select list in both the sets have 4 options - 00, 15, 30 & 45). The 3rd dropdown select list in both the sets is where users will select either AM or PM.
Now it's quite obvious that the start time can come after the end time (on the same date). For e.g. you can't let users select the start time as 9:00 AM & the end time as 6:00 AM.
How do I validate that the end time always comes after the start time & vice-versa?

I'm trying to compare an array to a variable and see if it has the same value then output the second part of the array:
<script language="javascript">
var photoCaptionID0 = "13006";
var photoCaptionID1 = "24018";
var photoCaptionID2 = "13002";
[Code]....
So using this example. If any of the first section in the array captionID (24001, 13001, etc) has the same value as photoCaptionID0, then print the second part of captionID (Item 1, Item 2, etc).

I'm trying to convert a string based on the contents of another string. For example, I have two strings - "Purple" and "Orange" and a variable "P" - I want the script to look at the word "Purple" and everytime is sees the letter "P", assign this to a third variable (result variable) - if the letter it's looking at is not a "p", I want it to take that character from "Orange" and add it to the result string. So the result would be "Prapge". This is the code I have so far, and it doesn't work, absolutely stumped as to why ...
