Check If The Textbox Matches The Pattern?

Feb 18, 2010

I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?

Code:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

[code]....

I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.

Check If None Of Array Matches.......

Nov 26, 2002

It's to allow users to create thier own descriptions, and the input is displayed automatically using innerHTML. This part of the function checks if the HTML tags are allowed through, I've got this far...

allowedHTML=new Array("<br>","<b>","</b>","<i>","</i>")
HTMLcount=allowedHTML.length
function formcheck() {
lettercount=document.formname.email.value.length
HTMLcheck=""
for(i=0;i<ltrcnt;i++){
if(document.prsnlsd.email.value.charAt(i)=="<"){openat=i}
if(document.prsnlsd.email.value.charAt(i)==">"){closeat=i+1
for(j=openat;j<closeat;j++){
HTMLcheck+=(document.formname.email.value.charAt(j))}
for(k=0;k<HTMLcount;k++){
if(HTMLcheck==allowedHTML[k]) return; else alert()}}}}}

I want it to trigger if one of the "allowedHTML" isn't found by the time it's finished going through the array.

JQuery :: Check If An Element Matches A Selector?

Jul 9, 2010

is there any way one can test if an element matches a jQuery selector? I'm not trying to locate elements, just test for match.

More specifically, when using event delegation and a common callback function for multiple events, is there a way to check the event's currentTarget against a selector?

In the following example, how can I check if the currentTarget is the LI node with class "item2"?

<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>

Change Image Only If .src Matches?

May 1, 2011

I have a form with two fields: shape and color. where people select a shape an image of the shape appears, and a default color image appears.When they select a color, it changes the color image. But if they go back and change the shape, I don't want it to turn the color back into the default image. But I don't know how to do this script.Here's the function I have, but I don't know how to write it:

function changecolor(picName,imgName)
{
var idx = filepath.pic4
if (idx = "/images/leaf_shapes/entire/transparent1.gif")

JQuery :: Selector That Matches Element With More Than One Child?

Oct 22, 2010

I was wondering if there is a "selector construct" that matches an element having more than one child. So I'm looking for a solution that doesn't need
an if statement such as;

if($('ul').children().size()>1)
{
//do this
}

[Code]....

But I'm looking for a selector that already looks for these conditions. Kind of like how :has() works but then a check for more than one child.
