JavaScript - How To Find Character Encoding In Any Site

Hi,
Sorry this is probably quite a noobish question, but I have a function which accepts the parameter "screen_name". I want to include this variable within some HTML, which is the code for a Twitter. Here is the function:

PHP Code:
var htmlTest = "<script src='http://widgets.twimg.com/j/2/widget.js'></script>" + 
"<script>" +
"new TWTR.Widget({" +
  "version: 2," +
  "type: 'profile'," +
  "rpp: 8," +
  "interval: 6000," +
  "width: 250," +
  "height: 300," +
  "theme: {" +
    "shell: {" +
      "background: '#0e428f'," +
      "color: '#ffffff'" +
    "}," +
    "tweets: {" +
      "background: '#ffffff'," +
      "color: '#615161'," +
      "links: '#0748eb'" +
    "}" +
  "}," +
  "features: {" +
    "scrollbar: false," +
    "loop: false," +
    "live: false," +
    "hashtags: true," +
    "timestamp: true," +
    "avatars: false," +
    "behavior: 'all'" +
  "}" +
"}).render().setUser('" + screen_name + "').start();" +
"</script>";
        var test = "hello";
        document.getElementById('dynamic-content').innerHTML = htmlTest;
    }
</script> 


The function works fine when I omit the HTML and just return "screen_name" to the target <div>, but it doesn't work as above. Can anyone spot what I'm doing wrong???

Hi all,

rightButton.innerHTML = (rightOutcome1Prob+" chance of "+rightOutcome1+"\r\n else "+rightOutcome2);

Hi Im new to javascript and need some help with a project I have, the task I have is:

Create a page that can take a bloke of text and out put the following
o How many times each letter occurs
o How many spaces
o How many words
o How many times each word occurs
o A list of things that are not words or special characters

I think maybe use an array but im not sure, like I said im new to this so not too sure on how to do it. I know it would read into a file say a txt file and sort through it this way, possibly using some kind of loop to read through all of the text before sorting it and I know it might use variables. I know how to kind of work through the task I have, but to actually implement the mechanics of the javascript is something that I then struggle with
Thanks to all that help.

Hello all,

I need assistance checking for valid characters in a username/password set up. I have been reading up on form validation but can't find exactly what I am looking for and need help deciphering what's going on.

I have a list of accepted characters: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789.-_@"
a-z, A-Z, 0-9, dot, dash, underscore, and at.

I want to then check an inputed string against that set and if a character is notin the accepted set, to send an alert.

Here is what I have gathered so far: a for loop that increments through the values' .length - this is what checks each individual character. Then use of indexOf() can tell me which character is unacceptable. Now is where I am stuck and coming to you. Please help

Specifically i was wondering if anyone had any ideas on how to select the specific character when hovering over a word?

I have not been able to find any documentation on this however, there is a demo site i found for a plugin that allows character selection.

i dont need anything that large and elaborate...

Edit I'm pretty wel experinced with jquery, I know it's possible with jquery

I'l not good in Javascript and I can't find anything about what I want.. .

On a sports website there is a table with our ranking and results. On this site the content is changed weekly, but it stays in the same tables.. .

Is it possible to make a javascript to get those tables and put them on my own website so the content will change on my site when the content is changed on the sports site?

Please help me, it would save me lot of time.. .

Hey Guys,

I wanted to prepend a character to menu items when the mouse will hove over them. An example of this is seen on the website of Minivegas, he http://minivegas.net/

When you hover over a menu item at the top a slash appears in front. There seems to happen a couple of things to smoothen out the effect of prepending the character. I was looking for a similarly smooth way of adding a character in front of my menu items.

Can anybody help me out on how to do this? I'm also unable to find out exactly how they did it on the Minivegas website.

Anybody any ideas?

Thanks in advance!

Regards,
Roy

Ok

I have a textarea field that is validated by Js, this textarea can and will contain the newline character

Code:

\n

so I validate in JS Code:

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

Code:

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.

Any ideas? Any suggestions as to how I can make php and javascript treat a newline as the same amount of characters?

Thanks in advance.

Suppose I have the string 'ello'.
I want to insert the letter 'h' in the beginning of that string.

How do I do that without using a special function? I can only use the functions charAt and indexOf - anyone has any idea?

I have the following code as shown below:

Code:

<script type="text/javascript">
var a = 12;
var b = 35;
var c = 56;

document.write(a.toString(36).toUpperCase() + "<br>");
document.write(b.toString(36).toUpperCase() + "<br>");
document.write(c.toString(36).toUpperCase() + "<br>");
</script>

The problem right now is that for the first 36 number, it always miss the 'prefix 0'.

From the code above, it will return the following:
Code:

C
Z
1K

My intention was to have all of them display in two character format, as shown below:
Code:

0C
0Z
1K

May I know how should I do it without having to use if (a < 36) else ... statement?
