Newline Different Character Length Php And Js
Nov 4, 2009
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?

only have test one browser - Mozilla - but have the impression, that newlines when setting innerHTML doesn't go down very well with the browser. Is this sufficient for causing a hard crash or at least an exception? Can anyone verify that? (Just a guess now at the moment)

I have a form with a textarea field. I want to validate the input from
the textarea using javascript. Suppose I want to check that the user
has not entered the string:
"Hello
World!"
To do this I am using the script:
form["text"].value == "Hello
World"
But this gives an "unterminated string constant error" because the
browser converts this to:
form["text"].value == "Hello
World"
So how do I do my check?

I have a text area in one of my forms that I want to control the character size of. In short, I want to keep the text area to 10,000 characters.
What I Have Found: I have found a number of scripts that will control the character length of the text area, while you are typing.
The Problem: If you cut and paste a document that contains 15,000 characters into the text area that is limited to 10,000 characters, it will still take all of the information (i.e. the 15,000 characters), as opposed to limiting/cutting it off.
Does anyone know of a script that will control the overall character length whether it be inserted via key stroke or is copy and pasted into the text area? Or possibly point me in the right direction?

I using the jquery_validate.js script to validate my registration page. Does a great job, but I need to increase the length of password characters from 6 to 8, with at least one number. This is the message a user gets:
HTML Code: Please enter at least 6 characters. I'm quite new to jQuery and I looked at the jQuery validation page and couldn't figure out how to change the parameters. It's suppose to be easy to modified by I'm at a loss as to how to change the rule from 6 to 8 and include a number.

I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..

I am using prototype.js and part of what is sent to formmail.cgi to be

I am trying to take the value of the textarea field, f1, and add from a select pull down menu = multiple additions are possible.
var x=document.getElementById('selectbox1')
...
document.forms[0].elements['f1'].value = document.forms[0].elements['f1'].value + x.options[x.selectedIndex].text;
I need to a /r/n or something like that but when I try it, it adds "/r/n" rather than a new line.

I am trying to retrieved the value of the textarea with the newline
preserved without having to submit the form to the server. Does anyone
knows how to? I tried soft and hard wrap but both does not seems to
affect the input in anyway.
Example :
<form name=frm>
<textarea name=ta wrap="soft"></textarea>
</form>
<script language=javascript>
alert(document.frm.ta.value) // <-- the alerted value should look
exactly as what is entered in the textbox.
</script>

In textareas or input textboxes, when you dynamically add '
' to the textbox's value, is it automatically converted to '
'? If it does, in what browsers does this happen? Firefox (and other Geckos)? Opera? Konqueror?

my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]
I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.

i need some creative input. i'm trying to enable the user to input a
length of time, from one day to about 10 years. ideas i've had have
been:
- 3 pull down boxes, for days, months, years
- an entry box for a value and a pull down box for units (days, weeks,
months, years)
- a scroll bar to slide along to a corresponding time
I'm not sure i should even use javascript, maybe an applet instead. I'd
really appreciated some new ideas or brainstorming.

I have a problem with getting the amount of childs in a XML structure,
the strucure is somewhat like the following:
<?xml version="1.0" encoding="iso-8859-1"?>
<cms>
<num>21</num>
<xmlnames>
<field>id</field>
<field>name</field>
<field>availablefrom</field>
<field>availableuntill</field>
<field>owner</field>
</xmlnames>
</cms>
If I use the following to get te amount of childs for xmlnames I get an
amount of 11:
xmlObj.responseXML.getElementsByTagName('xmlnames' )[0].childNodes.length
Is this wrong or maybe there is a better / other way of counting the
child amount?

I am running a bit of JS to highlight text inputs onFocus in IE. It
seems to be working on all of the forms on the site except one. The
debug code in the script displays the number of input elements in an
alert. On the page where it does not work, the alert is "[object]".
Here is the script:
function initHighlight() {
if (!document.getElementsByTagName){ return; }
var allfields = document.getElementsByTagName("input");
alert (allfields.length); // debug
for (var i=0; i<allfields.length; i++){
var field = allfields[i];
var attr = field.getAttribute("type");
if (attr == "text" || attr == "password") {
field.onfocus = function () {
this.className = 'highlightActiveField'
}
field.onblur = function () {this.className =
'highlightInactiveField'}
}
}
}
function addLoadEvent(func)
{
var oldonload = window.onload;
if (typeof window.onload != 'function'){ window.onload = func; }
else { window.onload = function() { oldonload(); func(); } }
}
var isIE = navigator.appName.indexOf("Microsoft") != -1;
if (isIE) { addLoadEvent(initHighlight); }
Unfortunately, I cannot reveal the URL of the page (contractural
restrictions).
Under what conditions would IE believe that the length of input fields
is an object, not a number? I have run the page through two
different validators and there are no errors.
