I've got this php code
Code PHP:
protected function sanatizeInputValue($value)
{
$dodgychars = "#[|!"'$£%&/()=?^<>*+-]#";
[code]....
How can I tanslate this in js code I tried but with very poor result.
I need to convert various chars with place holders in JS which will be then converted back in PHP. My problem is that in my JS code, if I have this string sequence ",,," my JS code is only changing the first comma char:
Rather than what I want which is:
How can I get the JS replace function to operate on all occurences of a char (comma in this case) and convert them?
I have a Javascript which is to count the number of characters entered into a Textarea box and to prevent any more characters from being added after a certain number has been reached. Here is the code:

E.g,
[code]
if ( xx[K]=="C" ) { N = 1;}
if ( xx[K]=="荐" ) { N = 2;}

I'm making a small web app and I want to upload files on the server. Everything works fine, but what I want to achieve is to remove any special chars in the value name.My value name is 'NewFile'. I want to remove any special chars from the name before the upload process, ex.: remove things likeAll I want to keep in the string is small caps english letters (no etc.) and numbers. no spaces.

I'm not very good in javascript, I took this code on the web.
i have the following code form counting the remaining words from a textarea which i took from the internet, but it does not work although i have adapted it to my page. i took it from this link : http:[url]....this is the java script:
<script type="text/javascript">
function textCounter(field, countfield, maxlimit) {
if (field.value.length > maxlimit) if too long...trim it![code]....
BTW, on the internet it was language="javascript" not type="text/javascript". Is this an old script or what?
I took the script for a remaining chars script form this page at: [url] and i've adapted it to my page, but it does not work? I just cannot figure out why.
Here's the script taken from this site that works
And this is my script

And this is my html where i have the form3 with textarea and text input
The problem is that it does nothig. The value in the input text stays the same (125).
I'm looking for a function that will convert non-ascii characters to unicode escaped string.For example, "あ" => "u3042".A similar piece of code is below. However, it convert strings to "\uxxxx" instead of "uxxxx". Changing "\" to "" in code below still won't work because that result in 'u' + 'xxxx' which print as "uxxxx".I have been searching for a few days already, and start wondering if this is at all possible. ; (
Code:
var unicodeEscape = function(str) {
var code, pref = {1: '\x0', 2: '\x', 3: '\u0', 4: '\u'};

I have a page working perfectly that passes up to 10-12k worth of data into a function via an 'onClick' event. That onClick is one of the <img..>'s attributes, directly. In case later that (dynamic) data gets larger, am I toying with potential problams because of some limit - either a limit in what can be passed into a JS function, or else a limit in the max num of characters allowed in an element's attribute(s)? What do you think is the reasonable amount that I can pass before things start to break? I may need to go up to 50k. 100k maybe, but I doubt that much.
View 6 Replies View RelatedI'm kind of new to js, I wanted to write some non english chars inside an array, and it only seems to work if I write unicode notation, e.g. "u1234" per char. I was wondering if there is some easier way to do this, maybe somehow specify to the browser that the js file is utf8-encoded or something similar, but I'm not sure how to do that.

Question: How can I force alert() to produce the same

unescape() does not work.
I have a textarea which the user can enter whatever text he chooses.
<TEXTAREA id=body name=body></TEXTAREA>
I would like to avoid supporting HTML tags in this textarea at the
moment, therefore I use the following HTML encode support:
Dim p_Body : p_Body = Server.HTMLEncode(Request.Form("Body"))
This works fine if I write text in latin characters (in English) - than
only the HTML tags are encoded.
But if I write text in other UTF-8 chars (e.g.: Hebrew) - all the text
is encoded, and it becomes unreadable.
I'm sure this has been answered several times before, but I haven't been able to find a post that addressed this issue, so here goes. I'm trying to access a <div>s title attribute. Problem is, it isn't escaping the / character. So for example, if the title is "Emergency/Disaster" it returns "Emergency". I'm using $('#div').attr('title').

I have run into a bit of a problem. If I want to set the html of an element via an ajax call but the content page has a peculiar apostrophe, it's sort of curved, not like a ' but a ’ (slight difference there) . When I view it in my browser it looks ok but if I try to get it via ajax all the ’ chars end up being question marks in black diamonds. How can I avoid this?
Umm and also could anyone tell me the origin of the curved type apostrophe? I feel stupid asking but I really am at a loss for what it is, I can't seem to actually make the character on my keyboard. I am thinking it could be Mac specific but that is a total guess.

I want to remove special characters in form fields. It should be automatic. I have a name filed where user entering text and i not want special characters, it should remove automatic.
something like this i need,
onkeyup="javascript:this.value=this.value.replace(/[^0-9]/g, '');"
here, all non-digits get removed automatic.
I need to limit the chars typed in a textarea to 160 (size of an SMS ) It works fine - as long as no one is copy-pasting text to it. Then my lil JS fails *boohoo*. So, could anyone help me out? Should I nail this to some other event than OnKeyPress or what?
[vbs]
function LimitText(fieldObj,maxChars)
{
var result = true;
if (fieldObj.value.length > maxChars)
{
result = false;
}
if (window.event)
{
window.event.returnValue = result;
}
return result;
}
Usage:
<textarea name="myTextArea" OnKeyPress="LimitText(this,160)">

I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button?
