I wrote the following function to get a font metrics table and it works for all printable characters except spaces. Does anyone know how I could get the width of a space char with known font, size etc...?
I tried several different variations on the "node.style.whiteSpace" line and also tried using an html entity (which gave me the width of the string ' ') but nothing seems to work. All I'm getting for spaces is zero width.
javascript Code:
function JSFontMetrics(inFont, inSize, inWeight, inVariant, inStyle)
{
var node= document.createElement('span');
var text= document.createTextNode('');
var width = 0;
I have very limited experience with web development so apologies if this is a stupid question. I'm using some code I found online to show/hide a table using javascript. Everything works as it should EXCEPT that in Firefox rather than having the table auto-size each column to fill up the entire width (900px), the table uses the minimum width for each column necessary to display all of the data. I've tried a number of things (setting overflow, manually specifying div width or table width, etc.) but nothing seems to get it to take up the full width as it does in IE and Chrome. You can see the page / code here: [URL]
The javscript I'm using is: Code: <script type="text/javascript"> function showHide(_myObj,_action) { var _myTableObj = document.getElementById((_myObj.parentNode.id).substring(0,(_myObj.parentNode.id).indexOf('_'))); if (_action == 'show') { .....
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. [URL]... 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.
Is there any way that one could have supersubs functionality applied to drop-down multi-column menus?I assume one would need to calculate the width of each column plus the combined width for the container.
I have a string that is encoded simply by replacing the letter with the next letter in the alphabeta. I need a function to convert it back. Following is the function:
function cnvtBack(encoded) { var orig = ""; for (i=0; i < encoded.length; i++) { var letter = ""; letter = encoded.charAt(i); if (letter > 'a' && letter <= 'z') letter = <<previous letter in alphabeta >> // HOW? orig += letter; } }
Please help me to get all characters from every line from a word-wrapped div using javascript.Need to get all the characters for first line, second line, third line,... separately from the word-wrapped div.
I currently have a website where i share thoughts with my friends (some kind of forum) and within this 'forum' people can post pictures they made but most of the time these pictures exceed the max width of my website so my website gets all streched out!So this is what i want: all images on the page must run thru some sort of function which checks if the image image width exceeds the max_width. if it does then the script must calculate how many pixels the current width exceeds the max_width and get this number so that the script does: current_width = current_width - (max_width - current_width)
I've recently start using Flexigrid (old JQuery grid plugin), and, as you may know, one of the few issue this really good grid plugin got is the lack of liquid layout option. My personal idea to solve the problem is to set the "width" parameter depending on $(window).width. Here is the problem (and here's why i post this question in "General use" and not in "Plugin").
The starting, and working, code is: $(document).ready(function(){ $("#flex1").flexigrid ( {

This work fine for me, but I supose it could be done way much elegant... maybe somethin without "IF" that could emulate the "%", like var percentage = $(#div.id).width()*0.XX with the 0.XX picked from an array of percentage, one for each column. Probably I should set up a function... ahhhh, as you may easily see I'm a total beginner with JQuery (and JS in general...)
I am trying to setup a javascript function that sets a div's width based on the combined width of the li's with the name "navItem". The problems I have been running into when trying to define the width of the li's is that they do not have a width defined in css. Can anyone help me out with this? The javascript function setWindow is suppose to show the div loginWindow and set the width of it.

Is there a way to calculate the .offsetLeft or .left of a character in a string relative the element that contains the string? I'm just trying to wrap each character in an element and position the characters independently, so I have to set the .position to absolute, and set the .left and .top on each element as I create it so I can move the elements later on.
I cannot remember the site nor the author, but it works BEAUTIFULLY! I have changed the timeoutInterval to 500 milliseconds as I type with one finger - the original was 250 or even less.
<script language="JavaScript"> // script allows you to type more than one character into a drop-down list // //A typical drop-down need to have ONKEYPRESS and ONKEY functions added // //Example: <SELECT ID='vc_DESCRIPTION' NAME='vc_DESCRIPTION' onkeypress='listbox_onkeypress()' onblur='listbox_onblur()'>
var toFind = ""; // keyboard buffer var timeoutID = ""; // process id for timer - when stopping the timeout var timeoutInterval = 500; // milliseconds - keyboard buffer var timeoutCtr = 0; // initialise of timer countdown var timeoutCtrLimit = 3; // number of times timer is allowed to count down var oControl = ""; // maintains a global reference to the user control
function listbox_onkeypress(){
window.clearInterval(timeoutID) oControl = window.event.srcElement; var keycode = window.event.keyCode;
if(keycode >= 32 ){ var c = String.fromCharCode(keycode); c = c.toUpperCase(); toFind += c ; find(); // search the listbox timeoutID = window.setInterval("idle()", timeoutInterval); // restart the timer } }
function listbox_onblur(){ // function is called when user leaves listbox
window.clearInterval(timeoutID); resetToFind(); }
function idle(){ // function is called if timeout expires - 3rd time stops timer and clear kb buffer
I have a form where users can enter text in one or two textareas. If they only enter text in of of the textareas I can limit the max char to 300 using this:
<script type="text/javascript"> var maxL=300;//nr of max permited characters function limit(obj){ var nr= document.getElementById('nrc') var v = new String(); s = obj.value.split(''); for(i=0;i<maxL;i++){v += s[i]} if(s.length>=maxL){ obj.value=v; nr.firstChild.data = maxL-v.length; } else{nr.firstChild.data = maxL-s.length;} } onload=function(){ document.getElementById('nrc').firstChild.data=maxL; } </script>
Is there a way that I can limit the total char between the two textareas i.e. If a user enters 180 in the first one they can only enter 120 in the second one.
Is the next jQuery code the best way to decrease an elements width?[code]I tried using the next code:[code]but that's not working, also not with '-20'.Maybe it's an idea to add this functionality? It's is already used in the .animate() function for changing the position of an element.
I need a code that when a button or image is clicked then a div's width and height are changed.
Ive managed to get a few codes that does this, but the real problem is that, the contents of the div is an embedded flash file and i thought that by setting the flash width and height to 100% then the flash would fit to the new size of the div, but it just didnt work.
I need a code that when a button is clicked then the div's and the flash's width and height are changed.
please have a look at the temp website latinunit net / temp / , you will understand where im coming from.
on the right hand side i have a flash chat in a div , div is controled by a script that allows it to follow the scrollers up and down.
My goal is to add a little button in the same div that says expand or maximise so when clicked the the div expands aswell as the flash file.
I would like to use one or more RegExps to validate country names as having the first and last words beginning with an uppercase letter, intermediate words beginning with either uppercase or lowercase, and all other characters being lowercase characters. For example:
Turks and Caicos
The difficult part is that I want to obtain save the string positions of the invalid characters in an array, rather than just obtain a true or false value.
Can anybody with more experience with Regular Expressions than me suggest some code, sites, or approaches.
I was using jquery-1.3.2.min.js to show a modal dialog on a button click event handler and this worked fine. The same did not work with jquery-1.4.2.min.js and yielded the following script error on my IE -8 broswer. Message: Exception thrown and not caught Line: 75 Char: 399
In textareas or input textboxes, when you dynamically add ' ' to the textbox's value, is it automatically converted to ' '? If it does, in what browsers does this happen? Firefox (and other Geckos)? Opera? Konqueror?
