I am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?
Code snipet
function fitStringToWidth(title,width,className) {
var span = document.createElement("span");
span.className="titleBar-Title-1";

I have the following code which will split the given input based on the comma(,) and will store each value in separate address of the same array.[code]...
How can we remove the empty values while displaying the output or how we can remove the spaces from array+
I have a div ( id="rightheader") and inside there is a table. The following code replace all content of the table with empty space and then remove the table header.
I have to create the 15 puzzle game and im having a difficult time getting started. i need to create a table (4x4) that has one empty space. All the other spaces must have a random generated value between 1 and 15. All i got so far is a onclick image swapping function.
I need a JS validation code for validating numbers such that,Empty space and characters(including + and -) shouldn't be allowed,there should be only one decimal point,spaces and characters between numbers also shouldn't be permitted.
I am looking for a method to make a html element empty (no innerHTML). This would be pretty easy if it weren't for IE. IE has the bug that innerHTML is read-only for tables (and some other elements too). So my function
function clearElement(id){ document.getElementById(id).innerHTML = ""; }
doesn't work on tables (and I need it to work on tables). Would there be any other way for me to do this in a way as general as possible. I don't want to bother with 2 different functions for what is essentially the same task and I'm curious how this could be solved in a nice way.
What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1); var s=r.concat([0,"",null,undefined]); alert (s.toSource()) //==="[, 0, "", null, (void 0)]" typeof s[0] //==="undefined" typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()... Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ... I guess the question is actually, "can you tell the difference between uninitialized and undefined"?
I developed a Grid that sometimes resides within a table. The Grid is created with the DOM and inserted in its parent element. Problem is that IE returns offsetWidth/offsetHeight 0 when you check its offsetWidth.
For example, the following code will return 0, while Firefox returns its correct width.
Code: <table border="1"> <tr> <td id="myCell"> Some text goes here... <script type="text/javascript"> alert(document.getElementById("myCell").offsetWidth); </script> </td> </tr> </table>
I read somewhere that IE renders the table once it has read the entire table, so my guess is that offsetWidth returns 0 because the table is not yet rendered and its not part of the DOM?
Anyway, if anybody would know how to avoid this it would be great. This problem does not appear inside a DIV, but in this very case it must be inside a table...
I'm currently developing an online work brief, where the user has to enter details regarding the project into a form. I've come to a section in the form where the user has the option of selecting between two checkboxes and an input element. I have to ensure that at least one of the checkboxes have been checked or that the input element is not empty. I've come up with this function:
function validateMedia(){ var count = 0; if(document.workBrief.mediaOnline.checked){ count++; } if(document.workBrief.mediaPrint.checked){ count++; } if(document.workBrief.mediaOther.value != ""){ count++; } if(count 0){ return true; }else{ alert('Please choose at least one media option'); return false; }}
I'm sure there is a more effiecient way of writing this.
I have reimplemented the non-standard <marquee> element (in a very simplified fashion), moving around a DIV using offsetParent and offsetWidth.
It works fine in Mozilla (1.7.5) and Safari (1.2.4), but fails miserably in IE6/Win : the content scrolls off screen to the right hand side, although it should be going to the left.....
When use text/html as header for my page the method element.offsetWIdth/Height work as usually and return the real width/height of an element, but when I use XML as type (which is necessary in modern browsers to use strict XHTML) the function returns just 0.
Can somebody help me, it's very important. The prototype function Element.getDimensions() doesn't work in strict mode.
I am trying to make a script that prints a date in the format Sunday 14th January 2007. Where the date that is displayed is the next sunday 3 weeks from now. For example today is 7th January. The script would print Sunday 28th January 2007. It would read that all of this week until next sunday when it would change to Sunday 4th February.
It's probably something with rounding off, or floating point problems. I have a timer which is used when solving the Rubik's cube. It has to measure an exact time, but the clock display I made shows a different value than the actual time (also displayed after session: ...). I am using the same variable for both displays. sometimes it's off by .02.
I'm building a form that is calulated based on the options selected with a javascript form. This is my first attempt at something like this so I'm a bit lost at the final update.
First to be sure I'm on spot here is the javascript I'm using to update the form - <script> function BDWcalc () {
I have a javascript that should convert any date into a number between 1 and 260. Based on the outcome of that calculation, a viewer is directed to a specific web page.How can I verify the calculation? How can I see what number javascript is arriving at so I can backtrack to the error? It is not serving up the correct page.
I have compared the results to a calculator on another website [URL] that uses a different script to calculate the same result -- that's why I am saying the end results are not correct. On the other website, scroll down to where you enter a date. It returns a name just above the date (example: July 25, 1970 returns Electric Star). The script I included above returns Yellow Sun. July 25, 1970 should = 68.
Please take a look at the picture below:When you enter the value of Volume and Unit Cost... it should automatically add up into Net Cost and VAT (including float number).
I currently have a web page that is building a web form from data contained in a SQL table. I need to do some calculations on the numbers that are populated into the form. I have used the following javascript code to successfully complete my calculations but I can only use this code at the bottom of my page because executing it at the top of my page the form fields are still empty. How would I use or modify the code I have to display the calc at the top of the web form. Example as follows:
f Code: unction up(){ var inpt= document.getElementById("item_one").value document.getElementById("aCom_total").value=Math.floor(inpt) } function up2(){ var inpt= document.getElementById("aCom_total").value [Code]....
I input the valve 100 in textone my total =100 I input the value into 20 text two my total is not 120, but 10020
I have a form which must calc the difference between 2 date fields and return the result in a third field. I have the following code but it does not seem to work. Can anyone tell this total newbie where he is going wrong or suggest a more elegant way of doing this.
<head><script> function doit(oForm, usrInp) { var one_day = 1000 * 60 * 60 * 24 ;
var userDate = new Date(usrInp) var dueDate = new Date(usrInp)
I've got a small problem here. I'm trying to write some code that would generate a drop-down menue for me, where I'd just need to enter the menu- and submenu items into an array. The items are to be displayed as text. Now, I want to have the layers with the submenues to appear more or less under the appropriate main menu items. For this I need to be able to calculate how many pixels a given text uses up on the screen of the user. That's all fine with IE and an unproportional font like courier. The problem is, there is this nice setting that allows you to change the diplay size of the text - which is pretty much disfunctional in IE, but in mozilla, it works. Which means that I can't just say that one letter in courier, size 2, is 4 pixels wide and be happy with my calculation, because then somebody can just pop up with another text diplay size and *boom* - my calculation is wrong again.
Now, is there a realistic way to find out how many pixels _exactly_ a piece of text takes up on the user's screen? Or can I make the given piece of text a DIV and then have some kind of document.divname.left that gives me the actual location of this text?
I'm creating this form that when you tick a checkbox, it adds the value of that checkbox to the running total. Then it displays the Calculation and Running total.
