Ajax :: Find HEIGHT Of DIV / When Inserted Some Text And Chaged It's Size?
Jan 4, 2010
I have a page with div layer where i insert text with innerHTML attribute into it. Depending on the ammount of text i have the HEIGHT of the layer is changing.if i leave the css part of it with no HEIGHT atribute at all, browser will not automaticaly calculate it and returns empty string on request layerName.style.height.if i assign some value to it("..height: 200px;..") it will not change it after uploading the text. It will change the size but on request layerName.style.height i'll get same 200px.
I am working on a UI that, when you click on a menu option, a div opens and show three divs inside. These divs all have different heights. The heights are based on the divs content.The problem I'm having is... how do I measure what the divs height should be? IE, how do I grab the height for a div BEFORE it has had any style applied to it.
I need to get text data from a web page which are unfortenately inserted into <span> tag by jQuery so it's not actually involved in HTML source file. That means for me I can't get it by classic HTTPRequest (programmatically).
For example, on this page: [URL]
When you enter some text in the textbox, this text will show up under it. But when you open HTML source or download it using HTTPRequest (I do so in C# language but it shouldn't matter), the source won't contain entered text. And this text is what I'm trying get to.
I've used to an AJAX call to load a HTML table into div. This is working successfully. I know want to use a click event on buttons located within the inserted table.
The click event is triggering on buttons outside the inserted table but not on the buttons within the table.
Do I need to call some sort of refresh function to so that jQuery is able to pick up these events?
I'm using formwizard, and I tried to insert a dropdown into the form by putting this jquery code $('#aog').change(function() { if ($('#aog').val()==='yes') { $.ajax ({ type: "POST", url: "<?php echo base_url(); ?>index.php/register/mortgator", data: "aog=" + $('#aog').val(), success: function(msg) { $("#bank").html(msg); $("#signupForm").formwizard("update_steps"); }}); //end of ajax } else { $("#bank").html(''); }}); //end of aog event
And this php code function mortgator(){ $this->load->model('MBank'); $q = $this->MBank->getbanklist(); echo '<label for="mortgator">Mortgator:</label><br/>'; echo '<select name="mortgator" id="mortgator" class="required ui-wizard-content ui-helper-reset ui-state-default error">'; echo '<option value="">Select a Mortgator</option>'; foreach ($q as $key => $list){ echo '<option value="'.$list['bankID'].'">'.$list['bankName'].'</option>'; } echo '</select>'; } It is working, except that when you click next, other form input boxes would fade, but this input inserted via ajax would not have a fade animation. That's why I added this line of code to the html tag ui-wizard-content ui-helper-reset ui-state-default error but it appears that that does not work.
Using $.get() and insertBefore() work great for what I'm doing. But, the data I insert does not respond to events that I have set up. I'm notsurprised by this. I'm sure there is something extra I need to do. But, what is that?
How can I find the height and width of a webpage? Say I want to make sure someone's webpage is within an 800X600 viewing area. Width is the most important but if I can get width, I should also be able to get height.
I don't need to modify the page in anyway. Just get the width and height. I can reference the page in an iframe, cfhttp (CFMX) or something if it needs to be on my server.
Does anyone know any js code to find the whole height of a web page?
i am trying to make an image that moves from the top of the page to the bottom like a marqee. if i use document.body.offsetHeight to tell the image how far to move before returning to the top, the image only goes as far as the window height not the whole page so if you scroll down the image never reaches the bottom.
can anyone please tell me code to find the total page height or a good substitute for the marquee tag?
P.S. this is the code i'm using to act on an image placed at the top of the page with the variable winH found using document.body.offsetHeight:
Is there a way to find out the normal value of line-height for an element ?I set the line-height of an element to 20px and I want to set it to normal via JavaScript only if the the normal value is > 20px.
I have an image that I set to have a width of 100%. I want it to be no higher than the screen height. Its inside a div which itself has no height limit set. So I thought I could set the image height to screen.height. But when I do that, it seems to be larger than the visible client area of Internet Explorer. I want it to fit within that space. I realize the image might be distorted by doing that, but thats OK.
I'm working on my personal website [URL] and I'm trying to use Javascript to edit some of the height and size attributes of elements on the page, based on the user's window size. I've got the code that gets the window size working, and calculates what I want to set as the "boxSize" but the part that goes into the external CSS to change the values is not working. "boxSize" is a variable that holds just a number. I'm not sure if it's really stored as a number or a string, but I don't think that's supposed to affect anything.
I'm just putting in the relevant part of the code right where it's failing. I figured out (using alert() statements) that the script is definitely working right up until before the two lines given, and failing to get through them.
As the title suggests, I want to grab the height of the center column and force my left and right columns to be the same height. The bit of code below is from MyWebTronics, and it's great (awesome job, Jason!)... but it is designed to grab the tallest column (regardless which one it is) and then set all the rest to the that same size.
Code JavaScript: <script language="javascript" type="text/javascript"> fixHeight=function(){ var divs,contDivs,maxHeight,divHeight,d; maxHeight=0; contDivs=[]; divs=document.getElementsByTagName('div'); // get all <div> elements in the document for(var i=0;i<divs.length;i++){ // for all divs... if(/"fixheight"/.test(divs[i].className)){ // find those with the class attribute 'fixheight'... d=divs[i]; contDivs[contDivs.length]=d; // determine their height, defined as either offsetHeight or pixelHeight if(d.offsetHeight){ divHeight=d.offsetHeight; } else if(d.style.pixelHeight){ divHeight=d.style.pixelHeight; } // Keep track of the largest div height maxHeight=Math.max(maxHeight,divHeight); }} // assign all divs the height of the tallest div for(var i=0;i<contDivs.length;i++){ contDivs[i].style.height=maxHeight + "px"; }} // Run fixheight on page load window.onload=function(){ if(document.getElementsByTagName){ fixHeight(); } }// ]]> </script>
In my case, I always want the center column to define the height for the left & right columns. SO... this means (1) I need to wrap my center column with <div class="fixheight"></div>. (2) I need to modify the portion below so that it will write my side columns (wrapped with <div class="sideheight"></div>) to the same height.
Code JavaScript: // assign all divs the height of the tallest div for(var i=0;i<contDivs.length;i++){ contDivs[i].style.height=maxHeight + "px"; } Javascript is not my specialty at all, and I'm hoping to rework this to write the sideheight style instead of fixheight.
I have a div that is float: left and has a bunch of divs inside it. Those divs inside are all position: relative. They also have z-index values. I want to know the actual height of the outer div's content when I add a div.
Here's the problem: Code: <div class="outer"> <div class="something_With_Z_Index_Of_Zero">Something</div> <div class="something_With_Z_Index_Of_One">Something</div> </div> (NOTE: Both inner divs have a height of 20px)
When I ask for either: outerDiv.offsetHeight or outerDiv's computedStyle.height, both give me 40 (or 40px). This is actually not right as the two inner divs are placed one over the other. How would I figure out the proper height?
I currently have multiple combos ofimage with a description text below it.I want to lay them out inrowsand inline. So if the width of page is not enough the next one should startbeginning of next row. Each image and text is currently house by a div with float left and a set width, but if you look at the attached screenshot (1.jpg), The Oracle - eBusiness Suite gets stuck because of the differentsheight due to text size and if I set a height too, then some of the text gets covered up (2.jpg). I was thinking if I can maybe use J Query to automatically adjust height to divs on the same rowto fit the biggest text size on that row?Evenjust changing all divs to that heightbe would be ok if it'seasier.
Is it possible to have a text box input searching for the entered text on another webpage in the same way Find In Page would do? I have a webpage that I want users to input an item, and that this will open the targeted webpage and bring you to (and highlight) the matched item(s) like find in page does. Is this possible or is the easiest way to just make users open the link to the target page and just complete the find in page search there?
I am using ajax / php where I am looking up some info from the database and populating a select list dynamically, however I am running into some sort of size limitation with the ajax.response object. If the string I am passing to javascript from php is too large javascript does not get it all the data. The magic number appears to be 6123 characters, anything below that it works fine, anything above and if I alert the ajax.response, I see the string is cutoff. Any ideas where this limitation is defined?
I have a div which contains dynamic content populated with AJAX (user has two select boxes to filter query results)However when filtered results extend past the initial height of the div in question, the div remains the same size and the results overflow out of my content area.I added a surrounding div with id of "limit" around the div that needs to grow and shrink ("resultsdiv"), but this didn't work; it ended up cutting off search results instead of growing the div (I also added position: relative; and overflow: hidden to my stylesheet, as suggested on the jquery website).
The animation is not important, this would work fine with .css({...}), but I thought it would be cool.At any rate, if this is supposed to work, my first question is: WHERE do I put this script? I've placed it outside of the query and outside of both divs (no luck). I've put it IN the div/query loop, but no go. I've even (just for kicks) put it in my ajax query file, but nothing.
I seem to be experiencing a character length cut-off with XMLHTTPRequest. I suspect this because the ActiveX .XMLHTTP works just fine for supporting IE. The data supposed to be recieved is a database outputting in an HTML table format. Any gecko based browser cuts off at about 4200 characters Code:
Having a problem with iframe resizing when the iframe body is a jsp file which contains a dynamically built ajax table. Users select different options from a drop down. All but 1 is a standard static jsp file. The other is a jsp file with a dynamic ajax table which is generated the second the user select this option from the drop down. Problem is the javascript is not getting the correct height for the dynamically ajaxed jsp file.
Here is the iframe which is loading the contents file. <iframe id="Editor" name="Editor" src="" scrolling="no" frameborder="0" allowtransparency="true" onLoad="resizeIframeToFitContent(this)"></iframe> Resize call: function resizeIframeToFitContent(iframe) { iframe.height = Editor.document.body.scrollHeight + 300; iframe.width = Editor.document.body.scrollWidth; } // resizeIframeToFitContent
As a current workaround I am adding 300 manually to the height this works but throws the height of the normal jsp files well out and makes the page to tall.
