I wanted to know if there was a way to select a rectangular section of
an image (like done with a cropping tool). The only way I've been able
to accomplish this is with applets and thats painfully slow. Is it
possible to do this via Javascript or perhaps DHTML. Any other
lightweight technique?
Using jQuery, the hide show part is easy. I need to show or hide a single section of a form based on the value of a select box. More specifically, if the select box is one of 30 countries, then show, else hide.
What's the easiest way to handle this?
How to make an image map link to another page AND open a specific accordion section?I guess I need a script that knows which area of the image map was clicked and not only navigate to page 2 but opens the section via slide toggle I need it too.Here is the the page with the image map (although image map version not upload yet so I have what will be uploaded below)[URL] ...and the page I need to navigate to based on the area of the image map clicked and also slidetoggling the div I need it [URL] Here is the image map:
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<img src="/Img/Illustrations/kicktalkv2.jpg"" alt="Kick Talk" usemap="#kicktalk_map" />

I cannot get javascript to change an image to make a "pressable" button when select areas of an image map are clicked. I used index.html for testing purposes.

<img name="light" src="standard-light.png" width="60" height="180" border="0"
usemap="#lightmap"></a>
<map name="lightmap" >

I am trying to figure out how to have multiple images, like a map, and when one image is clicked, have that value passed to the form. Code:
View 1 Replies View RelatedWhen I put the following code on a page the image on the page changes
when I mouse over the links. Now I was thinking I could instead create
a popup menu to change the image on the page, see second code sample.
But it doesn't work. What am I doing wrong? Or is this just not
possible? What am I missing? Code:
I have a webpage with a form. Depending on user selections at the top of
the page, the page will disable sections of the form. My plan is to put
each section between a <div></div>. Each section contains some collection
of form elements.
So if the user does not select some criteria, the related section of the
form gets disabled. In a typical Windows type of application these elements
get disabled and greyed out. What's the best way to do this in a webpage?
Can Javascript determine what form elements are in a div section and
disable these elements through a loop for example? I know I can disable
each element if I know its it but is there a way to find out all the IDs of
elements for some div section?
Is it possible to go to a section of a page when that pages loads? Ex:
<body onload="#idname">
I know that doesn't work, but I think it shows what I am trying to do.
how do I get rid of the space between the top div and the following div sections.I need to know what to replace the <br> tag with where I stop the floats with "style='clear:both'".how to slide the tab body sections into and out of the area below the top controlling <div> sections.All it does now is simply hide or show the sections and I would like to create a sliding illusion if possible.
View 2 Replies View Relateddoes anyone know how to apply onselectstart and ondragstart to just
one image on a page?
All of the posts I have found so far suggest adding these to the body
tag. The disadvantage of this is that it prevents users from selecting
anything at all on the page.
I need to isolate this to one particualr image. I've tried adding the
selectstarts to divs, the img tag etc but it doesn't seem to work.
I'd like to know if there's a possibility to select a random image .. but .. from a directory.
I've seen many posts regarding this subject, but all of them show the procedure once you have the image names inside an array.
I need to know how to select a random image from a directory that's filled with them, like let's say /public/images
Does anyone have a script, that can display a random image of the images I select?:confused:I'm going to use it for a type of captcha. I think this would be easier in javascript, so yes I am in the right section.
View 7 Replies View RelatedI have a form that shows some images with a radio button associated with each one. I would like to give them the option to click on the image to select the radio, but not sure the easiest way to pull it off.
I was assuming I add a OnClick to each image and use getelementbyid to check the button, but since all the radiobuttons have the same id (so they can only choose one) I am not sure how to make the correct radiobutton become checked.
Hope this makes sense, here is the simplified sample form:
<form>
<img src="image1.gif" />
<input id="radiobutton" type="radio" value="Image1" />
<img src="image2.gif" />
<input id="radiobutton" type="radio" value="Image2" />
<img src="image3.gif" />
<input id="radiobutton" type="radio" value="Image3" />
<img src="image4.gif" />
<input id="radiobutton" type="radio" value="Image4" />
</form>
I have made some application in JavaScript. I need some help from you friends.Whenever i click on some image i want that image should get selected. Same as we select when we drag on it with mouse. Hope u got what i mean.
View 7 Replies View RelatedI have inherited a project with some code that runs fine for some
frames but not for others. This is a frames based project, and
(apparently) sometimes there is a parent frame, and sometimes not. When
there is no parent frame, you see this error message:
'parent.frmUpper.document' is null or is not an object
I would like to know if there is a way to check for the existence of an
object by name so I can determine what to do next.
Is the UI section of the site down? I have a few websites that link to it and they're all taking forever to load, seemingly hanging when "waiting for ui.jquery.com..."
View 3 Replies View RelatedWhat I'd like to do is set up a section of my page so that the content cycles through at regular intervals. The actual application in this case is to change a banner image, its alt text, and the page it links to.
So if I had 3 variations:
It seems to me that the most intuitive way to do this would be to put them all in a div or something and have that div's content cycle between the snippets above. However, I'm not very familiar with JavaScript objects, properties, etc and don't know if this is even possible, let alone how to do it.
I've done a few web searches to see if I could find a script like this, but I mostly just came up with image rotation scripts. One of them provided a way to change the link as well, but it seemed that the link only changed on a click, so that (I believe) the status bar would show an incorrect destination when the banner was on any image but the first. None of the scripts I found would allow me to change the alt text as well.
Is there a way to have all three of these things cycle through simultaneously? Again, an ideal solution would allow me to cycle the entire section of HTML.
I was wondering if it's possible in ALL browsers (at least newer ones), to disable all elements within a section, without having to go through and disable every element individually? From my tests, it appears disabling a <tr> element with and id works in IE, but not in Firefox. Is there any cross browser solution? Or do I have to do it for every element within that section?
EDIT: With further research, it appears as though I can't just disable the <tr> element, and have it disable everything in the row (at least not in Firefox). Is there maybe a way to loop through with childNodes or something, and disable them that way?

There are a couple of things I'm having issues with and was hoping someone could point me in the right direction:1) When you click the check boxes, the image area is selected in red. I'd like to make it so when you click on mild=yellow, moderate=orange, severe=red. But as the colour is specified in default_options. How do I specify the colour for each check box separately?2) I'd like to move the text and check boxes to the top left of the image (I can get the image to float right, but can't seem to move the text (as an asp:panel) to the top left. It is still at the bottom, even after playing with the height etc.

The following code produces the images in the dropdown select box, but does not process the click function.
<select id="ipselect" name="ipselect" size="15" style="width:150px" >
<?php echo $IP; ?>
</select>
<script language="javascript" type="text/javascript">
[Code].....
Using the same code, I alter the $("#ipselect").msDropDown(); to a bogus ID such as ipselect1. The jquery dropdown select is gone, and the default select box is viewable. When I click one of the options, the click function processes with no issues. Is it not possible to use the click function with the dropdown select code? I think the image dropdown code was posted on the jquery site as a tutorial.
I am using the code below to load a resource via AJAX that contains a <ul id="photoCollection"> . That list has an image in each of its <li> tags. This markup and images are getting loaded as expected into the target Div#photoCollectionWrapper.
$('#photoCollectionWrapper').load('/photo_collections/1/photos', photosLoaded());
Once the images are loaded into the target div with AJAX I need to select them so I can alter their widths and heights. So far, I have been unable to select them as expected once they are loaded. However, If I just load them in a new page with NO AJAX, then buy using a simple .load() event handler I am able to select them after they have completely loaded as expected. No problem.
But when loading the resource via AJAX I am unable to select them at all. I am using a callback that gets fired after the AJAX is loaded. Then in there it seems "logical" to call my .load() handler on the images loaded in via AJAX. Here's a sample of some code just to illustrate the idea. The code below actually will not run at all. If I remove the .load() bit it will, but then Alert always returns null.
function photosLoaded() {
$('#photoCollection li img').load(function() {
alert($('#photoCollection li img').height());
}
}
I have also tried many css selector variations to try and select the target images, but to no avail. I know for sure photosLoaded() is getting called. I just can't select the elements that the AJAX call brought in.
