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 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
I know for a fact that it is an object and I'm pretty sure that it isn't null. I will give you a link to the page that I'm troubleshooting even though it's embarrassingly ugly. Does anyone have an idea of why it's not seeing the <select name=finish> on Line 183 in <Form Name="myform">?
getting first line coordinates of multiple line inline element.
Example HTML aaa bbb ccc ddd <span id="target">eee fff ggg hhh iii jjj</span>kkk lll mmm nnn ooo ppp qqq $(document).ready(function() {
[Code]....
Assume that span#target has a line break, when I see a browser. Then I click span#target, above function returns the head of coordinates which second line ("hhh") has. I want to have the coordinates which first line ("eee") has. How can I get that?
How do I read a local text file line by line, one line at a time. I got upto opening a file, and can read whole file at a time. But I want to read just one line at a time. May be have a counter of lenght of the file and read only the counter number line at a time.
<SCRIPT language=JavaScript> var fso = new ActiveXObject( 'Scripting.FileSystemObject' ); f = fso.OpenTextFile( "c:\mytextfile.txt", 1 );
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; } }
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 need a plugins or a UI , is some thing like count characters, for example i have a text box and max number of character in text box is 17 and i whan't to show the progres for example 14/17 (14 from 17)
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.
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.
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?
find a char sequence in a string and highlight that with red color.
In text box when they start typing i will get list of string matching in a div. for example when they start typing "A", i will get a result as Atlantic Alaska Atlanta, some thing like this. high light "A" in all the String of the list to red color, in the same way when they type "AT", then "AT" in red color.
I have a user that insists they have web applications that do this, and wants the one I'm building to do it too...
You have a table on an html form. As the user changes one or more fields in a table row and moves to the next line, the changed row should AUTOMATICALLY be sent back to the server and updated in the database.
If the user moves BACK to a line that's already been changed, and changed a field, a popup should display and ask "if the user really wants to change the field". If so, again, it should AUTOMATICALLY be sent to the server and updated in the database...
Ignoring the horridness of making that many round trips to the server and banging the database for every line, is there a way to AUTOMATICALLY do the equivalent of a submit and post the changed table row back to the php script?
