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 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'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";

I was wondering how you allow the user to highlight text they've typed (in a form) and click a button to edit its style (placing tags around the highlighted text).
Could someone explain this a little further and perhaps provide an example.
Alright, I'm using a Rooh.It WordPress plugin right now, but I don't like the way they do it, so I want to write my own code to do something similar.
I want the user to be able to select the text they want to highlight, and the background color of that text changes to whatever color they have selected.
How can I do this in JavaScript?
I'm working on implementing watermark in datepicker text field (JQuery V1.8.9). I have a datepicker field with watermark set (dd/mm/yyyy). Watermark text displaying in gray color.

View 3 Replies View RelatedSo I'm trying to change the background color of a textbox depending on how many characters are enter (putting it green/red depending on count), and I'm having a hell of a time. There are 50 different textbox IDs on the page (give or take, dynamically generated), each unique/sequentially numbered (id1, id2 ... id50).Now I'm not that good with Javascript, but this is what I can up with so far.I was trying to use 'this.id' so I wouldn't have to name each of the IDs.
View 2 Replies View RelatedI want to change the color of a each word in a block of text. For example I want each word in a sentence to change to a different color automatically.
I was thinking that is if it was possible to move the color tags around each word and put a time delay between each time it moves but how I will accomplish these two actions.
How on earth do you use javacript to change the text color of an input element, and have it work with IE??? I've tried numerous solutions. All of them work on browsers such as Mozilla. But none of them work on IE.
This works in every browser I've tried besides IE:
var whatever = document.createElement( 'input' );
whatever.type = 'text'
// (more code)...
whatever.style.color = 'black'
This also works for other browsers besides IE:
whatever.style.cssText = 'color:black;'
I've tried other things as well. Nothing works in IE. Is there anyway
to change the text color inside an input box dynamically, and have it
work in IE?

Anyways I have a textarea that I have managed through the magic of google to have the default text clear out with the onfocus and if the textarea is left blank to put the default text back in with onblur. I now have a new problem that is a little CSS and a little JS I suppose. I want the default text in the textarea to be grey and the user submitted text to be black. I know it is possible because... well facebook has it.
<tr>
<td colspan="2">
Invite via Email: <br />
<cftextarea name="emails" cols="50" rows="3" value="Separate Emails by Comma" onclick = "if (this.value == 'Separate Emails by Comma') this.value = '';" onblur = "if (this.value == '') this.value = 'Separate Emails by Comma';" ></cftextarea>
</td>
</tr>
I don't actually have to put the text in the JS Function, but to have it pull the default text from attribute that would be awesome to.
How can I change the text color in a span tag after a refresh?

I am currently successfully using the following code to randomly change the color of specified text ("quotations" - see below) each time the page is reloaded. The only problem is that the colors are too random. Instead of the code I now have, I'm looking for code that would allow me to define a distinct list of colors through which the text would randomly rotate each time the page loads. In other words, I want to choose each of the randomly loaded colors of my text.
<html><head>
<script type="text/javascript">
var quotations = new Array()
quotations[1]= "text1"
quotations[2]= "text2"
quotations[3]= "text3"
quotations[4]= "text4"
quotations[5]= "text5"
function display(){
a=Math.floor(Math.random()*quotations.length)
document.getElementById('quotation').innerHTML=quotations[a]
setTimeout("display()",500000) .....
}
</script>
<script language="Javascript">
function rancolour(){
var red = Math.floor(Math.random() * 255);
var green = Math.floor(Math.random() * 255);
var blue = Math.floor(Math.random() * 255);
document.all.main.style.color = 'rgb('+red+','+green+','+blue+')';
}
</script>
<link rel="stylesheet" type="text/css" href="/style.css">

<body onLoad="rancolour();">
<div id="main" style="color:#FF0062">

I have a regular expression that returns multiple matches. For e.g. If the user types a string "980ee,34223,werw" in a textbox, the regular expression match returns "ee" and "werw". I would like to highlight both "ee" and "werw" in the textbox.

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 RelatedI 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");

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.

There are two radio buttons, sometimes one will be disabled, other times the other will be disabled. I would like to make a script that: First: Changes the color of surrounding text of the disabled radio button to the color grey. Second: Checks the other radio button.
This was my plan: I would make a script that: First: Removes all the current classes and add the class "greyed_out" (or better: change only the color of) the parent element, all siblings and children of siblings (if any) of the radio button that is disabled at that time.Second: Sets the attribute "checked to the other radio button". I made a script, but when I set the bottom radio button to disabled the script doesn't work:
