JavaScript - Defining Div Width Equal To Undefined Amount Of Images Total Width
Hello, let me try to explain better what I'm trying to do. I'm a real newbie I don't know much javascript but I understand more or less the logic behind it... tell me if this solution should work and if you know how to do it please show me.
I have this page. http://felixdeportu.com/5/ The images are inside a div#content div#photo. I need to make div#photo's width to match the total width measurement of all the images it contains. If you load the page and you don't touch the size, it will work fine... but that's not realistic. If I resize the page, which will happen often on this kind of page (I'm assuming), the whole thing goes haywire (try it, scroll to the last image and resize the page you'll see what I mean). What can I do? Is my idea the right solution? Am I not explaining this clearly enough? Let me know please, I'm desperate. I've been trying to get CSS to do this for me for 3 hours now. Nothing works... Similar TutorialsHi, I'd like to set the div width equal to the image width. Here's what I can think of: Code: <script type="text/javascript">
window.onload = function ()
{
document.getElementById('foo').style.width = document.getElementById('bar').width + 'px';
}
</script>
<div id="foo" style="background:red;"><img id="bar" src="image.jpg"></div>
It seems to be working, but I'm not sure if it's correct coding. Thanks in advance for checking the code or any improvement you suggest! Rain lover Hey guys i am test my page in IE8 and i have a small problem the following script works in other browsers but not IE8 Code: function preload(arrayOfImages)
{
$(arrayOfImages).each(function ()
{
$('<img />').attr('width', '100px').attr('height', '100px').attr('src',this).appendTo('#img').attr('class', 'img');
setTimeout(this, 2000);
});
}
when i run this with lets say 100 images and all the image sizes are all diffrent and above 150px*150px when this runs it will preload the images fine BUT it loads the images with their defualt width & height and not 100px*100px any idea why this is? I want to set the width of a div to be the same width of the image inside the div. The following code works great. But... The images are different widths, so both wrappers are set to the width of the first image. Without having to add an ID to each wrapper or image, can the wrapper width be set to the image width using the name of the image as the unique identifier? Any help would be great! PHP Code: jQuery: $(document).ready(function(){ var newWidth = $('div.wrapper img').attr('width'); $('div.wrapper').width(newWidth); }); HTML: <div class="wrapper"> <p><img src="image1.jpg" width="200" /><br /> Caption</p> </div> <div class="wrapper"> <p><img src="image2.jpg" width="250" /><br /> Caption</p> </div> Hi, I am thinking of how to write the code for this: There are 4 textboxes, 3 of which allow you to enter any number (e.g. 1000, 2500, 12345, 100.10, etc.). So whenever I entered a number in one of them (or two or all of them), the 4th read-only textbox will automatically shows the total of the values in the 3 textboxes. So...can anyone give me any references to this? Thanks. I have a text field. I want the text field to change / be calculated on the action made on the dropdown menu... So if I select Debit card.. it should leave the amount as is.. If I selected Credit Card it should add a percentage to the Amount. Please dont just provide a solutoin.. but please explain as i would love to understand why Code:

Hi, i followed a tutorial online on how to use Javascript to calculate total price. Everything works fine, when all the dropdown select value has it's own value and does not correspond to each other. Eg : Cake Type : Round $4.00 Cake Color : Red $3.00 Cake Filling : Raspberry $4.00 So total is $11.00 The problem comes when you want to add Cake Layers and the price of Cake Color changes based on No of Layers - 1 Layer , 2 Layer and so on. Eg: Cake Layer : Layer 1 $5.00 | Layer 2 $2.50 | Layer 3 $2.50 (for color Orange) Cake Layer : Layer 1 $7.00 | Layer 2 $4.00 | Layer 3 $4.00 (for color Red) Do i have to use if and else conditional statement for every possibility? I am just a beginner. Attached below is the example code i have so far.. Code: var filling_prices= new Array();
filling_prices["None"]=0;
filling_prices["Lemon"]=5;
filling_prices["Custard"]=5;
filling_prices["Fudge"]=7;
filling_prices["Mocha"]=8;
filling_prices["Raspberry"]=10;
function getFillingPrice()
{
var cakeFillingPrice=0;
//Get a reference to the form id="cakeform"
var theForm = document.forms["cakeform"];
//Get a reference to the select id="filling"
var selectedFilling = theForm.elements["filling"];
//set cakeFilling Price equal to value user chose
//For example filling_prices["Lemon".value] would be equal to 5
cakeFillingPrice = filling_prices[selectedFilling.value];
//finally we return cakeFillingPrice
return cakeFillingPrice;
}
This is for the calculation Code: function calculateTotal()
{
//Here we get the total price by calling our function
//Each function returns a number so by calling them we add the values they return together
var cakePrice = getCakeSizePrice() + getFillingPrice() + candlesPrice();
//display the result
var divobj = document.getElementById('totalPrice');
divobj.style.display='block';
divobj.innerHTML = "Total Price For the Cake $"+cakePrice;
}
Some sample of the HTML Code: <select id="filling" name='filling' onchange="calculateTotal()">
<option value="None">Select Filling</option>
<option value="Lemon">Lemon($5)</option>
<option value="Custard">Custard($5)</option>
<option value="Fudge">Fudge($7)</option>
<option value="Mocha">Mocha($8)</option>
<option value="Raspberry">Raspberry($10)</option>
Is there a better way of simplifying this calculation method ? How do i change the price of form values based on selected values on previous dropdown. Thanks in advance. I need some help on my math equation, I got the calculations and confirm.submit, and the alert messages to all work properly, but when I go to put the data into the math equation, I am coming up with some outrageous number way off from what it is supposed to be. What I am trying to accomplish is to take the calculated number of day and hours and minutes; multiply the total time in hours by the equipment cost per hour and calculate the total amount of rent. My problem I think is in the calculate total amount of rent section in the script. Please help, your expertise is greatly appreciated. Below is the math equation in the script section: Code: //calculate days from date field
function checkit() {
var today = new Date();
var nowyear = today.getFullYear();
var d1 = document.forms[0].pickupDate.value.split("/");
var yr = d1[2];
var mm = d1[0]-1;
var dy = d1[1];
var OK1 = checkValidDate(yr,mm,dy);
if ((yr < nowyear || yr > nowyear +1)) {OK1 = false} // only valid for current year and next year
var d2 = document.forms[0].returnDate.value.split("/");
yr = d2[2];
mm = d2[0]-1;
dy = d2[1];
var OK2 = checkValidDate(yr,mm,dy);
if ((yr < nowyear || yr > nowyear+2)) {OK2 = false}
if ((!OK1) || (!OK2)) {
alert ("Invalid dates\(s\) or incorrect format! Please try again.");
document.forms[0].pickupDate.value = "";
document.forms[0].returnDate.value = "";
return false;
}
// arbitrary or example start and end times obtained from elsewhere (select lists)
var fhrs = parseFloat(document.forms[0].pickupHours.value);
var fmins = parseFloat(document.forms[0].pickupMinutes.value);
var shrs = parseFloat(document.forms[0].returnHours.value);
var smins = parseFloat(document.forms[0].returnMinutes.value);
var firstDate = new Date(d1[2],d1[0]-1,d1[1],fhrs,fmins); // note month must be 0-11!! Also note USA date format
var secondDate = new Date(d2[2],d2[0]-1,d2[1],shrs,smins);
var difference = secondDate.getTime() - firstDate.getTime();
var secs = difference/1000;
var days = Math.floor(secs/86400);
secs %= 86400;
var hours= Math.floor(secs/3600);
if (hours<10) {hours = "0" + hours}
secs %= 3600;
var mins = Math.floor(secs/60);
if (mins<10) {mins = "0" + mins}
alert ("Time Difference is " + days + " Days " + hours + " Hours " + mins + " Minutes");
//calculate total amount of rent
var equip = parseFloat(document.forms[0].equipment.value);
var total = (((days * 24) + hours + mins) * equip);
var OK = window.confirm(" The total rental cost is $" + total + "\n Click OK to accept, Cancel to decline");
if (OK) {return true}
else {return false}
}
function checkValidDate(yr,mm,dy) {
var nd = new Date();
nd.setFullYear(yr,mm,dy); // YYYY,MM(0-11),DD
var ndmm = nd.getMonth();
if (ndmm != mm) {
return false;
}
else {
return true;
}
}

Need to set the width of a Table that is being spit out by this god awful CMS... please help me... change the html attribute width! Working on a simple JS/jQuery-driven game where the user clicks on a cup to see if it is a winner or not. If so, it plays a happy sound; if not, it plays a sad sound. Everything is working great so far, except for the sound. The html is being set correctly when a cup is selected, but Firebug is telling me the sound files are undefined. Same when I enter the function: playSound("[filename].WAV") in the console. Any help or advice is greatly appreciated. Code: var cupRaised = false;
var winningCup;
function determineWinner(raisedCup){
if(raisedCup == winningCup){
playSound("applause.WAV");
} else {
playSound("sad-trombone.WAV");
}
}
function playSound(file){
$('#sound_element').html("<embed src='file/"+file+"' hidden='true' autostart='true' loop='false' />");
}
function raiseCup(num){
if(!cupRaised){
var cur = "#cup" + num.toString();
$(cur).animate({"top": "-=100px"}, "slow");
cupRaised = true;
determineWinner(num);
}
}
I have a the following code for displaying a tooltip: Code: <a style='margin-left: 10px; position:relative' class="tooltip" title="This is some text to display"> The javascript for the tooltip is as follows: Code: $(document).ready(function(){
$("a.tooltip").live( {
mouseenter:
function(e){
this.t = this.title;
this.title = "";
$("body").append("<p id='tooltip'>"+ this.t +"</p>");
$("#tooltip")
.css("top",(e.pageY - 10) + "px")
.css("left",(e.pageX + 20) + "px")
.fadeIn("fast");
var css_width = $('#tooltip').width();
var text_width = $('#tooltip').textWidth();
if (css_width > text_width) {
$('#tooltip').width(text_width);
}
},
mouseleave:
function(){
this.title = this.t;
$("#tooltip").remove();
}
}
);
});
$.fn.textWidth = function textWidth() {
var html_org = $(this).html();
var html_calc = '<span>' + html_org + '</span>';
$(this).html(html_calc);
var width= $(this).find('span:first').width();
$(this).html(html_org);
return width;
}
What I want to do is to be able to add another variable 'width' to be able to set the width of the tooltip like so: Code: <a style='margin-left: 10px; position:relative' class="tooltip" width="100" title="This is some text to display"> This width will then be passed into the javascript above and used to set the width of the tooltip. How can I modify the above code to do this?? Thanks 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 ! http://www.hannahdesign.co.nz/client...ing-collateral So here is what I have done so far: - Used FlexCroll (1) to make custom scrollbars on the top image panel - In the scrollbar - I have used a no-repeat background image that is 17px in width Problems: - When loading a vertical scrollbar appears - The horizontal scrollbar does not go all the way to the end Here is what I want to do: - Disable the vertical scrollbar for ONLY this div (this same script is used for another vertical scrollbar - http://www.hannahdesign.co.nz/client/summary) - Make the horizontal scrollbar limited to 17px or another set width. I have included both my CSS and the uncompressed JS. (1) - FlexCroll - http://www.hesido.com/web.php?page=customscrollbar Hi After searching on Google and looking on numerous forums I can't seem to find a good solution which works the way I want. I have a select box which is a set width. Some of the text in the dropdown list is longer than the set width. In Firefox / Chrome the width of the dropdown will expand to display all the text, and thats exactly how I want it. However, in IE7 the width of the dropdown will not expand. I do not want to resize the select box itself as it will mess up the look of the page. I know this is an issue with IE but was wondering is there any solution, or can anyone point me in the direction of a solution. See attachments on a simple example to see what I mean. I'm sure there must be some fix for this, maybe JavaScript. Any ideas would be great. Here is some simple code used in the screenshots Code: <html> <head> <body> <select id="list" style="width:100px;"> <option value="text1">Some text</option> <option value="text2">Some longer text</option> <option value="text3">Some even longer text</option> </select> </body> </head> </html> Hi, I'm trying to change the column from javascript using. cell.width='7'; or cell.style.width="7px"; when i set this. all the columns in each row within the table are resetting to this column width. How can i make sure that this reflects for only one row for which i set this property to. Please let me know. 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 Hi, Here are sample divisions: Code: <style type="text/css">
#grandparent {width:100px;}
#parent {overflow:auto; height:100px; }
.child {overflow:hidden; margin-left:10px;}
</style>
<div id="grandparent">
<div id="parent">
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
<div class="child">1000000000000000000000000</div>
</div>
</div>
The <div class="child"> width value is always 10 pixels less than <div id="parent"> width value. How can it be calculated so any width value is given to <div id="parent">, its child gets 10 pixels less than that? Any help is very much appreciated! Mike Hey all, I'm a new Javascript coder; it's still pretty easy for me to get snagged on stuff. Anyways, I had a question for a specific project I've been trying to figure out. I have an element set with CSS to a width of 160px. What I want is a way for users to the site to drag a slider back and forth to set the width of the button. Some sort of smooth animation while this is happening would also be nice. I'd also like a way to set a max width on the element. So, can this be done? I'm guessing it would use jQuery, but I don't really know. Does anyone have any ideas? AA |
