Function To Change Image Only If .src Matches?

May 1, 2011

how to make a function that changes a specific image on a page when the user chooses from a menu, but only if the src name matches "transparent.gif"

With numerous other scripts, I've cornered myself into this as the only solution for now to what I'm trying to do. But the script is not working. Here it is:

Code:

<script>
function changecolor(picName,imgName)
{
var leafcolor = document.getElementById('pic4').src;

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")

Function Change() - On Link Click, Image Changes From One To Another.?

Mar 6, 2009

I found it difficult trying to put a short and concise title for you all to understand.My problem: Basically, I have an image (its a + sign), when clicked I need this + to change to a -. When clicked again, it needs to return to being a +.Below is the current code I am using:

<script type="text/javascript">
imgs=Array("positive.PNG","negative.PNG");
var x=0;[code]....

This code works fine if I just have one instance of it. But If I want multiple ones, one stops working and the other functions instead.
I tried the following:

<p><a href="#"><img src="positive.PNG" alt="" onmousedown="change()" id="test" border=0></a></p>
<p><a href="#"><img src="positive.PNG" alt="" onmousedown="change()" id="test" border=0></a></p>

This causes the problem I explained above.I also tried specifying an id in the function change() syntax, but I couldn't get that to work.

JQuery :: $('td[colspan]') Matches Every Td In IE?

Sep 24, 2010

In IE (tested 7 and 8), $('td[colspan]') seems to match every single td. In Firefox and Safari, though, it (correctly) returns only those which do have a colspan attribute. Here is a simple test:

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.

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.

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>

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.

Regex Matches Periods But Not Square Brackets?

Dec 17, 2010

Can't figure out why the pattern will match a period but not a square bracket.For example, it will match "See Jack run." but not "See [Jack] run.". Just ignores the brackets.

Code:
var title = note_title.value;
// validate periods and brackets

ContentFlow - Change The ActiveItem Onclick To Just Bump It Over To The Next Image As If The Next Image Had Been Clicked

Jul 20, 2010

I am using ContentFlow from [URL] It is very well documented on their website. I got the whole thing working great on my site. What I don't know is how to change the ActiveItem onclick to just bump it over to the next image as if the next image had been clicked. As of right now it opens the image source in a self window. I don't want that. Can anyone give me a clue or maybe the whole answer on how to get it to click over to the next image? I believe the answer lies in the contentflow_src.js file.

Text Swap - Change Each Image To Different Image On Mouseover

Jun 15, 2010

I'm failing to get a pure CSS way to achieve this, so trying JS. Several small images in a row, each different. Want mouseover to:

1. change each image to different image on mouseover (each image has its own mouseover image version).

2. produce different paragraph of text below row of images on each mouseover.

I can achieve it with mouseover on text links or on an image, but not with the two events, viz mouseover image swap + mouseover text swap. Would also want to be able to style the text.
