Sequences Of Alphabetical Characters Using JavaScript
Jul 13, 2006
I've been looking at this for a while now and I just can't get my head around it. What i need to do is put together a program which allows the user to type in a sequence of letters and then tells the user how many times they have included the letter 'a' in their sequence. So far i have put this together but the output is totally wrong at the moment and it often either just says 1 or 4. Code:
I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

I bought a Javascript book (Sam's Teach Yourself Javascript in 21 days) recently and there is some code in it that doesn't run properly. Can anyone explain to me why this sorting algorithm doesn't work? Code:
jQuery.crSpline - Smooth 2D animation along paths of multiple waypoints, using Catmull-Rom splines.
Demo GitHub You provide: A series of (x,y) points that the path should follow. Plugin provides: Animation along a smooth 2D path that intersects all points. Check out the demo page to see what it looks like.
[Code]...
I just published an early release of this and am looking for feedback from other developers! I made it because I needed an easy way to make animations out of extended sequences of coordinates (without doing the math to stitch together bezier curves), and as far as I could tell no one else had published an easy method to animate along Catmull-Rom splines using jQuery. This is the result, and the hope is that it will be super easy to use and helpful for people besides just me.
Future plans: More general animations and customizable behavior. The current version only animates top and left properties along whole pixel values. It also assumes that every segment of the path should take equal time, resulting in some strange speed changes when moving from small to large segments. Currently brainstorming good fixes for all of these.
I have an Unordered List, each List Item has a div nested inside with an ID.
I am constantly adding to this list, it has to be in alphabetical order, so its kind of a pain to update. I thought I could make things a little easier by using a javascript array to sort it out via the nested div ID. But I can't figure it out..
I don't want to click, i just want the page to load already in place. code...
In IE, it looks like you can have to many characters in a javascript function.
The content of an entire html page is put into this function...
function updateTemplate(content) { content=content.replace(/'/g, '''); content=content.replace(/"/g, '"'); content=content.replace(/</g, '<'); content=content.replace(/>/g, '>'); Element.update('template',content); } it seems to cut off the content after about 2060 characters. is that an IE thing or is there something wrong with my code. FF does it fine...
I have a custom object named #cdata-section, however I am unable to access this object and get a run time "Illegal Character" javascript error. my object looks like this:
data.news.story[i].body.#cdata-section
The pound sign is causing problems. How can I use this object in my javascript source? Right now I'm trying something like this to escape the pound sign:
I have built a page on a recruitment website which allows users to upload their CV via ASPUpload i.e a browse button. However I want to limit the file type to just MS Word documents as I do want them uploading large PowerPoint files etc. My idea is to have some javascript which evaluates the last 4 characters of the file name to ensure it is .doc So if they try to upload anything other than a .doc file a dialogue box will appear stating that they must only upload MS Word Document (when they click the ‘Upload CV’ button).
Does anyone know how I can evaluate the last 4 characters of the file name? Once the user has browsed to their CV on their PC the path & file name will appear in a text field called ‘CV’.
Initially the form is loaded using ASP and HTML and the ü codes display the characters correctly. I have the values stored in a javascript array so that I can more easily and dynamically change the state/region dropdown when the country changes. However, when my javascript code tries to add the new option and print out new region the literal value such as "Würrtemberg" is displayed instead of the special character.
I am having problems with the code below (obviously) coming up with illegal character for various characters within the field name which is: S_Gift Finder1_0
I have tried various ways of escaping the characters but to no avail.
I am unable to change the name of the field as it it comes from an external off-the-shelf package. Code ....
I have character counter for textarea wich counting the characters. Special character needs same place as two normal characters because of 16-bit encoding.
Counter is counting -2 when special character is added like some language specific char.
Depending on an input value, I would like to output greek characters (f. e. those between U+03B1 to U+03C9. One way would be to define two arrays: one with the possible input values ("abgde...") and a second array with the corresponding values ("u03b1u03b2u03b3...").
But I hoped I could skip the second by a computation, f.e. "g" has index 2 in the first array, so output "u03b1"+2.
This does not work (of course). But do I have a chance to "compute" the output value?
I have the following script which takes the url of a page, strips out the / and sets the id of the body tag.the trouble is I only want the first 8 Characters Here is the code so far:
$(document).ready(function() { var pathname = window.location.pathname; var pathSlashesReplaced = pathname.replace(///g, "-");
I have got a code which selects the whole text inside a div element on base of its id. But I need to modify it to select the lets say first 300 characters. Can someone suggest something. It is related to moving end of range. I will also keep trying... Here comes the code
Code:
var textC=document.getElementById(divID); if (document.selection) { var div = document.body.createTextRange();
[Code].....
Only tested with FF3 , else part works fine for FF3 but need to move end point of range ... and stuck here
I have a bordered div with some text in it. Some of the text is one long string and thus runs outside of the div. The div stretches out to the width of the browser window so that long string of text runs all the way out past the edge of the scrollbar.
Is there a way I can use JavaScript to detect the width of the div from the edge of one border to the next and then convert that number into the number of characters that can fill that width?
I have a script which gathers information from a form and, if needed, writes this info to a 'preview' window. At times {tokens} are used in place of real html tags. How can I tell the script to look for "{" and "}" and replace them, respectively, with "<" and ">".
I tried using "str = str.replace(/{/g, "<").replace(/}/g, ">");" but that didn't work. The script in question is being written by PHP... thus, may be generating a syntax-based failure. Any ideas?
I am copying from microsoft word a simple word into my application(rich text editor).. i get special characters added to it. how can i get rid of them?
I have this code that only allows a period and numbers to be put in the text box. The problem is that the message also appears if the text box is left blank. I don't want the error to appear if the text box is left blank. Right now I have it on a Blur so that the error message appears when the person clicks outside of the text box.
<script language=javascript> function checkNumeric(value) { var anum=/(^d+$)|(^d+.d+$)/
I have a input filed of type "textbox" into which I am expecting to get currency values (ie. 199.99). Is there a way that I can restrict the user to only entering 2 values after the decimal point?
I can restrict the maxlength to 5, but that wouldn't stop the user from type in 1.987.
I am building a web page to show a TCP/IP raw packet.
I need to show "special characters" on the web page I am working on. When I say "special characters" i am talking about tabs, whitespace, crazy unicode characters, etc etc.
What is the best way to present this to the user?
I am thinking that a large textarea is the only way to display it so it retains all the special characters.
I need to set a cookie containing a Russian character string as the value, using the construct "document.cookie = ...". The whole project runs in the UTF-8 encoding.
The Internet Explorer handles this cookie correctly, whereas the FireFox writes only some byte gargabe and then reads it back.
I have a problem displaying a divbox containing a html-textarea - everything works fine with "normal" characters. However, when the textarea contains special chars like <P> or ' , the box fails to show:
