JavaScript - [ask] Get Div Height From Another File
hi guys.. i have a problem..
first i have a about_us.php page.. which inside the about_us page i include right banner page.. using php include.. and this right banner page height must be the same height as the about_us page.. so i need using js to get the actually about_us page height and send to right_banner page so i can process it.. my logic are get the div height from about_us page.. send it to right_banner page.. and using php to process it,so the right banner height can be similar to about_us page when about_us page open by user.. about_us.php i using div input all the stuff Code: <div class="mainarticel">text goes here </div> and mainarticle css i put in outside css.. called style.css nb:mainarticle height i using auto; and in right_banner page i using Code: function getHeight (id) {
var gh = document.getElementById(id).offsetHeight;
alert (gh);}
but this cannot get the div from another file.. so how can i get the div height from another file? Similar TutorialsHi, I need to re-size a div to be 100% of the browser but taking into account the height of an existing header div. Currently it works but it doesn't factor the height of the above header div, and therefore scrolls off the page (the height of the header div) I need to manipulate ( subtract the height value of the header) in the javascript somehow.

Thanks I can get this code to take two separate sections of a file which are not beside each other and write them into another file. It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help? Code: try{
while (in.hasNextLine())
{
String line = in.nextLine();
out.println( line);
int i=0;
if(!Character.isDigit(line.charAt(i))) { i++; }
studentStringNumber = line.substring(0, i);
String stringResult = line.substring(i);
studentStringNumber = studentStringNumber.trim();
stringResults = stringResults.trim();
double stringResultsValue = Double.parseDouble(stringResults.trim());
stringResults = in.nextLine();
studentStringNumber = in.nextLine();
studentNumber = Integer.parseInt(studentStringNumber);
if(in.hasNextInt())
{
int value = in.nextInt();
}
results = Double.parseDouble(stringResults);
if(in.hasNextDouble())
{
double value = in.nextDouble();
}
Scanner lineScanner = new Scanner(line);
studentStringNumber = lineScanner.next();
while(!lineScanner.hasNextDouble())
{
studentStringNumber = studentStringNumber+ " " +lineScanner.next();
}
stringResultsValue = lineScanner.nextDouble();
}
}

Hi i am using javascript for the first time and i have a problem .I have 2 files html and javascript file in seperate but i donot know how to make them work .the code is down below .Thanks in advance for help.

All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I'm trying to make height of my leftNav div the same height as the mainContent div. currently I have Code: jQ(document).ready(function() {
//even the left bar and the main Content
jQ('#leftNav').height( jQ('#mainContent').innerHeight() );
});
This only works on some pages, and not on others. for example it works here http://nminvestigates.townsendwebdd.com/index.php but not here http://nminvestigates.townsendwebdd...._prepared2.php Help please I just placed this div named iframe_container in a table cell. There's an iframe and another div inside of it and when I went to fine tune the alignment I discovered I could change the width of the div but not the height I can set it to 200 or 1000, it doesn't make the slightest difference. It seems to be clinging to the outside of the iframe. I can make it bigger by inserting breaks after the iframe but then the compass_rose div loses its absolute position for some reason I searched the page for height tags that might be interfering with this but I've turned up squat. I took the height specs off the table but still no effect. Can anyone spot the problem? <td style="width: 800px; height: 700px" valign="top" class="style3" align="left"> <div id="iframe_container" style="width:1000px; height=700; position: relative; overflow-x:auto; overflow-y:hidden"> <div id="compass_rose" style="top: 5px; left: 1200px; position: absolute; z-index: 2; visibility:visible;"><img alt="Compass Rose" src="compass_rose_animated2.gif" width="80" height="80" /></div> <iframe id="viewer" width="1600" height="635" src="front_page2.jpg" marginwidth="1" marginheight="1" name="viewer"></iframe> </div> </td> </tr> </table> Can DIV located in the MasterPage be resized depending on the screen resolution? <tr style="vertical-align: top;"><td> <div id="mainArea"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server" /> </div></td></tr> I've tried unsuccessfully - var height = screen.height; var area1 = document.getElementById('ctl00_mainArea'); if (height == 1024) { area1.setAttribute("height", "700px"); } else if (height == 864) { area1.setAttribute("height", "540px"); } Also tried area1.style.height = 700 + "px"; (no luck as well) This works: Code: <div id="oDiv" style="width:300;height:100;background-color:#000000;"></div>
<a href="#" onclick="getHght('exp');">Expand</a>
<a href="#" onclick="getHght('con');">Contract</a>
<script type="text/javascript">
<!--
function getHght(act){
var doc = document.getElementById("oDiv");
if (act == "exp"){
doc.style.height = 300 ;
} else if (act == "con"){
doc.style.height = 100 ;
}
}
//-->
</script>
This is exhibits the desired functionality, but it doesn't work: Code: <div id="oDiv" style="width:300;height:100;background-color:#000000;"></div>
<a href="#" onclick="getHght('exp');">Expand</a>
<a href="#" onclick="getHght('con');">Contract</a>
<script type="text/javascript">
<!--
function getHght(act){
var doc = document.getElementById("oDiv");
if (act == "exp"){
doc.style.height += 30 ;
} else if (act == "con"){
doc.style.height -= 30 ;
}
}

IE give an "invalid argument" error. No error in FF. I had the same [failed] result using .getAttribute(), and .setAttribute(). How should I approach this? -james Hello... Just curious on what I am doing wrong: I want to get the pixelHeight of a div called content and assign it to a variable. Then I want to use that variable as the css top position property for another div. I'm new to Javascript, but am learning it. Right now I am just having trouble assigning the variable. I get 'undefined' when I try to output the variable to the browser. Here's the code : Code: <script language="javascript">
var divh = document.getElementById('top').style.pixelHeight;
</script>
</head>
<body>
<!-- output divh -->
<script language="javascript">
document.write(divh);
</script>
this gives me undefined in my browser What am I doing wrong?? Thanks Kevin I am struggling to find a solution that enables me to have a div that is a certain percentage height of the window and then when the user is using a different resolution, it remains at that percentage of the screen height - not going off of the bottom as I have a fixed percentage no scroll full background image. I have sorted it for width but can't get it to work for height. any ideas? lol Bee x Hello guys ! I'm fairly new to JavaScript, so this is maybe an obvious mistake, but here is the code that doesn't work, it goes inside the body of my document : Code: <script type="text/javascript">
aImg = new Image();
aImg.src = "myimage.jpg";
aHeight = aImg.height;
aWidth = aImg.width;
document.write(aHeight + "," + aWidth);
document.write("<img src=" + aImg.src + ">");
</script>
While the image is displayed, the value written for the height and width is "0". This code worked fine when I compiled it in the "Tryit Editor" of w3schools.com (I told you I was new to JS :P), but it fails when I insert it in a page and then view the page with Google Chrome or IE7. Of course this is not all fo the code, I intend to display the image differently depending of its size... but I need to get that part right before moving on Any help would be greatly apreciated, thanks ! Hey guys, so i have a comment section. And what i want to do is if the height of the comment box is larger then lets say 100px. I want to set the height of the comment box to 50px and then display a "read more" button. And this read more button would toggle and allow the height to be "auto" and not set to 50px. so my html would look like this Code: <div class="comment-section"> <div class="comment"><p>This is where text would go. </p></div> <div class="read-more">Read More</div> </div> I have the class "read-more" set to "display:none" How would i do this? This is what i have / was trying and have been unsuccessful Code: <script type="text/javascript">
$(function(if ($".comment".style.height > 100px;){
{
$".comment".style.height = 50px;
$".read-more".style.display = block;
}
});
</script>
Hi Folks, Hope someone can help. I want to do this with js and not with any html/css tables, image fills or whatever other trick, but I don't know how... Say I have multiple DIV containers below each other, which contain multiple DIV boxes floating next to each other. None of the DIV elements have a fixed height: Code: <div id="container1"> <div id="box1">some text</div> <div id="box2">some double more text</div> <div id="box3">some other text</div> </div> <div id="container2"> <div id="box4">some double more text</div> <div id="box5">some more text</div> <div id="box6">some other text</div> </div> I want for each container (separately) to have the contained box divs to fit the biggest one in height. For example, in container1, if box2 contains more text than the others, I want box1 and box3 height to fit box2. And in container2, if box4 has more text than the others, I want box5 and box6 height to fit box4, etc. In my dreamworld, the solution would be flexible and fully automated, which means, it would look for all container divs of class x or Id x and apply the same rule to all child divs. Hope it's clear enough ;o) I have heard of jquery "equalheights" plugin but I don't think it can do that ? or then I misunderstood something. Could I be using some "get element by class" function and then apply a style.height to the divs? TIA for any suggestion Hi My html document contain many images which has the attribute src of img tag as the flowing : PHP Code: http://images.mysite.com/a/p/ap.eba553af4b719.ec03.jpg?x=210&y=83&q=85&sig=Tua1ukyUEVKTPSsz7xGPsg-- All those images has the common source folder http://images.mysite.com/a/p This is an example : PHP Code: <img src = "http://images.mysite.com/a/p/ap.eba553af4b719.ec03.jpg?x=210&y=83&q=85&sig=Tua1ukyUEVKTPSsz7xGPsg--" width = "105" height = "73" > I tried during many days to find the solution using RegExp but I didn't arrives. What I want to do is I - change for all image from the seem folder the src attribute to match the exact url of the image without special characters, for this example : PHP Code: http://images.mysite.com/a/p/ap.eba553af4b719.ec03.jpg?x=210&y=83&q=85&sig=Tua1ukyUEVKTPSsz7xGPsg-- Became : PHP Code: http://images.mysite.com/a/p/ap.eba553af4b719.ec03.jpg II - Control the width and height of the image by changing its height and width attributes resp. from two javascript variables : PHP Code: var v_width = 320 // Just for example var v_height = 250 // Just for example This is an example of try didn't work for me, for the first issue : PHP Code: var element = document.getElementsByTagName("img"); for(var i=0;i<element.length;) { var myString = new String(); var myRegExp = new RegExp("http:\/\/d\.images\.mysite\.com\/a\/p[^\?]*(jpg|png|gif)","i"); var myRegExp0 = new RegExp("\?.*","i"); myString = element[i].getAttribute("src"); if(myRegExp.test(myString)) { var newString = myString.replace(myRegExp0,""); element[i].setAttribute("src",newString); } } Help me please Think you i want to set the second container's height according to the first container's.but how to achieve the height of the container dynamically. thank you! It appears Lightbox has a bug in IE when the screen height exceeds 65,505 pixels. I have created two test pages for you to see. One that shows the bug and another that shows it working. The problem seems to be ONLY with Internet Explorer (of any version). In the following test htm pages click the "Click Here" link at the top left corner. You will see a lightbox pop up on screen. The issue is related to the opacity level. When the screen height is <= 65,505 pixels the opacity works fine for IE. But if the height >=65,506 it fails. It is not an IE bug because i tried using filter: alpha(opacity) and it works fine. It seems to be a lightbox bug. Test 1: Opacity Works because Height of Screen is 65,505 pixels: http://fatcatdaily.com/test-works.htm Test 2: Opacity Fails because Height of Screen is 65,506 pixels: http://fatcatdaily.com/test-fail.htm NOTE: You MUST be using Internet Explorer to see the BUG |
