Specifically, assume I have a div tag of absolute dimensions. I need to figure out, first, whether or not the text inside the div tag is partially hidden by the overflow setting, and if so, what the hidden text is.
Is this even possible? Obviously, the rendering engine in the browser "knows" this information, but is it accessible through Javascript?
I have a pop-up window system on my site that shows an absolutely-positioned div over the entire page as a "pop up" of sorts when someone clicks a link. I use this simple line of Javascript to disable page scrolling when a "pop up" box is opened by a user:
The problem is that when a user is scrolled down on a page and clicks a link to bring up one of my pop up boxes, when the overflow is set to 'hidden' to disable scrolling, the page "jolts" back up to the top (similar as to what would happen if someone clicked an <a> element with href="#" ). However, the links are not actually links, but span tags that are programmed with JS to trigger the scrollbar to be disabled when clicked, so that is not the culprit here. I've narrowed the problem down to that one line of code which I posted earlier. Apparently, setting the documentElement overflow style to 'hidden' scrolls the user to the top of the page automatically along with "disabling" the scroll bar on the page.
I am wondering if there is a way to prevent this jolting to the top of the page each time that JS code is triggered. I don't want users to have to scroll back down to where they were each time they open a pop up dialogue box on my site, as this would be detrimental for usability purposes.
I'm currently building a website that has a flash fullscreen popup at the beginning. The flash popup loads fullscreen, therefor I've set overflow-y to hidden. As soon as the flash popup is done, it removes the div it the flash is in using javascript, but I can't figure out how to put the overflow-y to visible.
I'm assuming I need to build a Javascript function to show overflow-y visible, and then need to call to that function from the flash file. I just can't figure out how to build the javascript function since I suck at javascript.
All the CSS is in the original file, so not in an external stylesheet, this needs to stay that way because I have to implement the code in to several different web sites.
Is there any way to test if there is overflow in a text area (i.e. a scrollbar is displayed)? This is a read only field so I could change the textarea to a div if necessary.
In the top right of the page is a JavaScript (Prototype) Carousel that scrolls through images when you click the arrows. It works properly in all browsers except IE 6 & 7 (it does work properly in IE 8) with my primary concern being IE 7. When you click on the right arrow to scroll to the next image it scrolls properly but the entire strip of images is displayed and it sites on top of the page's content.I've tried all of the overflow:hidden hacks I could find so.
I've been trying to implement a smooth scrolling animation in my page, which works fine in firefox and IE8 (haven't tested any older versions yet). But doesn't seem to work in google chrome (and probably safari either I guess). I have 4 divs on my page, positioned absolutely 2 by 2, only one div should be visible at a time, so the body has gotten an overflow:hidden. When an anchor-link to one of those divs is clicked the javascript gets its position,then scrolls towards it. etting the position works, but the scrolling does not work in chrome.
Now, when I remove 'overflow: hidden' from the body element, the scrolling does work in chrome, but of course adds the scrollbars which I don't want.
Trying to get the height of an element whose height is specified in the CSS.
So I am trying to animate the height of an item, where I have: <img id="myButton" src="myimage.jpg" /> <div id="myDiv" style="height:50px;overflow:hidden"> asdklf
[Code]....
However, it only registers as 50, even if the element is 500
I want to test if I get a overflow in a fixed sized div and in that case add 'overflow:scroll' to the div. I guess there is a way to check if a generated contents (from PHP) will create an overflow but how?
Most Jquery I have seen 'pushes' the content above or below it up or down the page as it reveals the hidden content, the above example reveals the content over the top without pushing out any other content which is what I am looking for I have tried to take the code and everything works aside from those tabs!! I was hoping somebody has a link to another site that does the same effect
'When my form is submitted, I have onsubmit pointed to the following code snippet. But, the button is not actually set to disabled and the style.visibility changes are not made for several seconds. It appears that it goes into validateForm and doing the rest of this snippet before the browser makes the changes.
How can I get the browser to immediately make the UI change?
function submitForm(servleturl) { var submitbuttonelem = document.getElementById("submit"); submitbuttonelem.disabled = true; document.getElementById("modgradeform").style.visibility="hidden"; var mydiv = document.getElementById("contentarea"); mydiv.innerHTML = "Validating the form."; mydiv.style.visibility="visible"; var ret = validateForm();
I am very new to jquery and I am trying to set the value of a textarea which is not in a form, into a hidden field which is in a form. In the text area, I have given it an id called refnote and ive used the text() to get the text in it. However, the problem is setting the retrieved text in a hidden form field. $('form').submit(function(){ alert ($('#refnotes').text()); return false; });
I have an idea for a little script.....I'm just stuck on one little part: When a user changes the value in a input or textarea box, I want it to change the value of a certain hidden input tag too.
Here's what I have so far:
function getNewValue(inputhidden, textinput) { var data = document.getElementById(inputhidden); var text = document.getElementById(textinput); data.value = text.value;
How can I obtain content of cascade style, using javascript? I know, there's a code document.getElementById('id').style.border='5px solid blue'; For example, but I need to do reversed operation, not to change style, but obtain it.
I'm trying to access the contents of a style tag in an ajax loaded document. Within the primary document, this (yaml inspired psuedocode) works just dandy:
html index.html head style body{color:red} script jquery
[code]....
I get a "this[0].innerHTML is undefined" error.Now, it appears as though "data" is being returned a simple string. I attempted to add "html" as a "type" parameter to the get, like this:
I'm trying to achieve something that I originally thought would be very simple, but I can't get it working....and even googling hasn't helped this time! All I want to do is update the innerHTML of a div with the content of a textarea object when a button is clicked. I'm trying to avoid having to post the form using AJAX because the button also replaces the innerHTML of a different div with the value of a text input box. Here is the code I've tried, but it doesn't work:
Code:
function previewContent(intContentId) { var titleText = document.getElementById('edit_title_' + intContentId); var titleDiv = document.getElementById('content_title_' + intContentId);
[Code]....
In this example, the titleText var represents the text input box, and the contentText var is the textarea. The titleDiv gets correctly updated with the current value of the input box, but the contentDiv doesn't seem to consider any changes I make within the textarea - it just loads the original content. This seems very strange to me. Is there an easy way to retrieve the value of the textarea?
I am using the following code to hide a <tr>. The script does its job, however before hiding the <tr>, when the cookie is set to true the hidden content flickers for half a second before being hidden. Is there something I am doing wrong or is the problem in style.display="none";?
function ShowHide(DivId) { var DivId=document.getElementById(DivId); if(document.form3.showhide.checked==false) { DivId.style.display = "inline"; createCookie("showhide",""); } else { DivId.style.display="none"; createCookie("showhide","true"); }}
I have imported css and link to my page. It works fine for all other browsers except Safari browser. When I am loading the page in Safari4 all the page content loads without style. My CSS hosted in CDN.
I am trying to populate a preview div with the content of a textarea. I have 2 textareas on the page. One with ID compose and another with ID profile_signature. Each has its own preview button named respectivly #profile_sig_preview and #msg_preview. however no matter which button is clicked the div is always populated with the content of the first textarea ie profile_signature. I tired setting up 2 divs so the content could be seperated but that did the same thing.
