I need help with javascript regular expressions.I have a text box in which user can enter only 4 types of values.
1) Varchar(n) where 0 < n <=80. Ex: Varchar(20)
2) Char(n) where 0 < n <=80. Ex: Char(20)
3) numeric(x,y) where x>y and 1<= x <=35 and 0<= y <=15. Ex: numeric(20,6)
If the text box value doesnot match this pattern, we should throw him alert message.
I have a text box.I need to
1) search the database for the words user is typing in the text box. This will happen with each key press.
2) if there is a match - I need to change the text color.
How can I achieve this?
Basically I have an text field with an id of s_username As the user types I want to append this to a var so I can display what the user has entered at the side of the screen, I have been using this for select boxes:
var ramCost = $("#ram").val();
I'm trying to change what the user types in a text field if they hit a certain key combination. For example, "cx".
This code checks for the letter "x" to be pressed, then checks to see if the second to last letter is the letter "c". If it is, then it deletes the letter "x" and replaces the "c" with the letter "ĉ".
Code:
// This code checks for a certain keypress combo. For example cx, Cx, gx, Gx, etc...
// The hard to type esperanto characters we aim to insert.
var esperanto_c = "ĉ";
[Code].....

I'm adding a sub menu to my portfolio page that will allow a user to filter the types of projects they want to see, but I'm not really sure how to approach this. I have a variety of web design and motion graphics projects all on the same page, and I want the user to be able to "uncheck" one category or the other, and when they do, all the divs for the unchecked category will fade out. This is the page: [URL] Does that make sense? What I'm thinking of doing is applying a unique ID to the different categories, then build a little JS that will change the opacity of those specific IDs somehow. I am not a JS ninja though, and I'm thinking there is probably a more efficient way.
View 1 Replies View RelatedHow can I use jQuery to submit multiple forms with different types, values, and actions? For example:
Code:
<form name="form1" method="get" action="submit1.php">
<input name="value1" type="text" value="">
</form>[code]....
Can I start the jQuery process from within a function when clicking on the submit button?
I'd like to create a quick and dirty validation method for a form. It's not meant to be very secure.
The way I picture it working is this - there is an input field that asks for a password. If the user types in the password correctly, the "submit" div tag will change from "none" to "block". , which will display the submit button. I just am not familiar with JS enough to know if that's possible.
Here's what I'm starting with:
Code:
JavaScript hides its memory structure.
I know that numbers, booleans, null and undefined are value types
(value is directed saved in a variable).
I want to know:
- How JavaScript distinguishes value types from reference types by
seeing the variable content?
- How many bytes are allocated in memory when I declare the following?
var i;
I can program in JavaScript without understanding them.
But I'm curious.
I have a form that has a bunch of text inputs, and I would like to select all that don't already have a class "errorClass" assigned to them. My JQuery currently is:
$('input[type="text"]').addClass("idleField");
But that adds the class "idleField" to ALL text fields, overriding the ones that already had the class "errorClass" assigned to it. What is the proper syntax to add the "idleField" class to all text inputs that don't have the "errorClass" assigned?
Does anybody know if it is possible to reference only text inputs, and not radio and checkboxes, and if so, how?

The application works fine but it makes the user enter the answer twice before it brings up the question "Would you like to continue?". I thought the fix would be to just call "myMH.checkAnswer(studentAnswer);" straight from the method in the "appclass" but that didn't fix it I m so lost on this problem. This problem most likely is right in front of my face but don't see it lol. I have another question as well but I think if I get this one figured out first it might answer my other one.
View 2 Replies View RelatedI am new to JavaScript and was wonder how I would go about creating a form to allow the user to enter various words, one at a time. These words are added to an array and displayed in the page using the textarea form element. Each time a new word is entered, it is added to the array, and then the array is sorted in alphabetical order before the words in the array are displayed in the textarea, one per line. I have tried lots and lots of different methods to accomplish this, and I can get it half working when I use the alert function, but I need this to display on the page in a textarea rather than in an alert box, I tried to get it to write to the page using a document.write function, but like I said I am new to JavaScript and unfortunately cant get any of it working.

Right now I am stumped and can not figure out exactly how to do what I want. Or even where to start. What I would like to do is build out a webpage where people can come, enter in values in different tables and then hit "Calculate" and get the results back on the same page.A break down would be:
Collection 1 (has the following: )
Table A Table B Table C
-----
[code]....
var IdContainer = new Array(); for(i=0; i < SEARCHNO; ++i) { var search_ID = xmlDoc.getElementsByTagName("searchID")[i]; var SEARCHID = search_ID.firstChild.nodeValue; if(SEARCHID !== IDCONTAINER) { code to add the SEARCHID to the IDCONTAINER array here
Now what i want it to do is every time the for loop runs the if statement checks whether the SEARCHID variable is not equal to the values in the IDCONTAINER array....if this is the case then the code after the if is run and the value in the SEARCHID variable is added to the IDCONTAINER array.
Problem is i dont know how to structure the if statement to check all the values in the array against the SEARCHID and then i dont know how to update the array afetr the if with the new SEARCHID.
today I am creating a form where a user can enter prices for things. I want to use javascript to display a total so far and it should update automatically as the user
nters/changes new prices.I have a form which looks something like this:
<form method="post" action="mailer.php" name="contact">
Price 1 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()">
Price 2 <input type="text" name="stampprice[]" size="5" onchange="calculate_total()">
[code]....
I have a form that gets values that a user has selected from a list menu field, that end up like this added to the URL:[url]
Instead of the Field being mentioned more than once, how can I have it where it could mention the field once with the values coma separated eg:[url]
Would I use JS to change the URL? or VBscript?
I am working on a online video portal build on flash/actionScript.
If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.
So I am planning to claer the cache.
how to clear the cache when a user enters something in address bar and press enter key?
I have a intern page with a form. User should enter their data and send the form. Some data from the user is stored in a database (name,phone). I want to make the form easier and complete the form with data from the database. The user should only enter his personal-number. How can i solve this with jquery? Is there any plugin?
