JQuery :: Bring An Element To Be Visible On Screen?

Apr 20, 2010

I have a setup where clicking on one of several spots on the screen shows one of the two forms that are hidden by default. I was wondering if there's a way to scroll the screen so this element is visible. Otherwise I can open below the fold and people will not know that something happened. The elements that I click on are not hyperlinks, jut regular divs. I was wondering if there's some method I overlooked that lets me take the page to a specific element.

JQuery :: Getting Around Click Function Making Hidden Element Visible

Sep 20, 2010

I have a class hidden by default at the document ready state. I use the show() function when its parent has been clicked and I want to be able to apply a click function to this newly visible element - when I write it I am finding that it is overriding the initial hide(). How do I work around this? I should say that this element is just a bit of text that says "close x" and will be used to "close" its parent div down...

Show The Class If Its Not Visible ,or Hide It If It Is Visible?

Jun 23, 2010

I have the following code that don't work like i want it.

Code:
function hideDisplaySingleSuite(textstring) {
var myclass1 = new RegExp('\b'+textstring+'\b');
//Populate the array with all the page tags[code]....

For example.It show objects if I remove the if statement that checks if the class is visible.for example this shows a class and works.

Code:
function hideDisplaySingleSuite(textstring) {
var myclass1 = new RegExp('\b'+textstring+'\b');
//Populate the array with all the page tags[code]....

So my question is why don't this work on a class, it works on an "id"?

Code:
if (allPageTags[i].style.display ==''){
allPageTags[i].style.display = 'none';
}[code]....

I want to show the class if its not visible or hide it if it is visible.How can this be done?

JQuery :: Draggable Element Only Draggable And Visible Between Certain Coordinates?

Nov 3, 2011

Is it possible to have a draggable div that will only be draggable between certain coordinates? in other words create a window through which the draggable div is visible and draggable. Would you use a stop drag when cursor hits a certain point? my div is a map and will be about 2000px by 2000px and want to have a fixed position and size of 500px by 500px so that that is all the user will see or be able to interact with. I know in image slider plugins that the divs scroll to the side or up and down through what appears to be a window so it should be possible?

How To Scroll Only What Is Visible?

Jul 20, 2005

I have a HTML content with some pages defined as <div>...</div>. One of them is visible while the rest is hidden (the visibility can be changed on client side). The problem: standard window scroller counts whole content (visible and hidden) so empty space is also scrolled. I'd like
it to behave as only visible content is to be scrolled (not empty space). The same applies to print (window.print). It prints not only what is visible, but also empty pages for these div's which are not visible.

How to set scroller (and print method) to take only visible content of page?

Only Visible To Non CSS Users?

Oct 12, 2001

Is there a way to show something to visitors *only* if they have css turned off?

How many people do turn style sheets off, or have browsers that don't support it?

I have a great layout design idea, but without css on, it'll look awful. Most of the stuff I can get around, but not one item that'll make one area of the page almost unreadable . Unfortunatly, that one area is the site navigation ...

Determine If Scrollbar Is Visible?

Jul 23, 2005

Is there anyway to determine if a DIV with its overflow style set to
auto has the scrollbars visible? I have a dynamically built table inside
my DIV. If the table is over a certain height and the scrollbars appear,
I want to shrink the width of my table. If the table's height doesn't
exceed the div's height, I want the table to be the same width as the
div. Any ideas?

Visible Div Disappears When Clicking On Second Div

Aug 10, 2011

After much searching and head-scratching (JS is not my forte!), I adapted some code to do what I want - well, almost! So here I am back again. I need to have three divs on a page, with each separate div changing onClick. Below is the code so far.

Two problems:

1) when I open it in a browser window both divs show, then the one disappears when I click on the second div leaving only the numbers. How can I change it so that both divs remain open?

2) Instead of the numbers [1], [2], etc. to change the divs, I'd like to have to just click on one single 'click here for more' to display the next div then return to the first after the last one. Can this be integrated or is it too late?

Possible To Discriminate A Visible DIV From A Hidden With Same ID From JS?

Oct 2, 2009

I have a mootools accordion in the website I'm building that uses two classes: "toggler" for the titles and "element" for the content.

I'm in the need of adding an input field at the bottom of the "element" DIV that the user has opened.

Problem is, every content of every different toggle has the same id="element".

The only difference is that the one opened has the visibility set to "visible".

Is there a way so I can write in that visible DIV from Javascript?
