Modify String - Lowercase Letters And Uppercase Letters In A String And Then Swap Them
Jan 19, 2010I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.
JQuery :: $("selector" - Code) And .html() - Load Div In A Variable - Modify It In Another Variable And Then Change The Document Injecting The Contents
Dec 13, 2011I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

Regarding Variables And Creating A Variable Name?
Jan 7, 2010I'm trying to create a family tree online that has several other related family charts. I want each person's name and birth year to be stored in javascript variables, then I want to be able to just go through the tree, and put the persons name once, and have it put the appropriate name and birthyear in the little boxes that the css is creating.
var johnname = "John Smith";
var johnbirthyear = "Jan 1 1930";
var janename = "Jane Doe";
[code]....
So I thought I had it all figured out. I thought that the above would take the id of John that I added, go to the line that sets the name, add john to the word name, and then document write the variable of johnname from the js file. I know you're laughing at me because of course it instead made the value of name to johnname, then wrote the word johnname in the box. I want to go through and be able to just type the persons name in the html for that box once, and have it update with their appropriate info.
Creating Html Link Using Variable?
Apr 12, 2011I'm using a form data reference, something like P-1234 for example to create a text file and a link to the file. This is during the construction of a new table or table row with javascript. I have an array of one or more references submitted via form using $_POST. On my action page I am creating a txt file P-1234. If I am creating a table ot table row using createElement(), one of the cells will have a link to the file. If the file is created as follows:
$File = $_POST['ref'][$i] . "txt";
After creating the cell
var Cell = document.createElement('td');
[code]....
I assume the link is inserted using innerHTML? If so, do I just append the filename to the end of the file path like this?
Cell.innerHTML = "http://localhost/Project/+File";
Creating And Referencing Previous Variable?
Nov 6, 2009I'm trying to build a page that shows random, alternating divs, and have looked at this page as an example. However, the issue at the moment is that although the divs display randomly, they do not disappear in order.The finished "page" is to be referenced by another page that I do not have control over. Here is the section of the file containing JavaScript:
<script type="text/javascript">
var curcontentindex=0
var messages=new Array()
[code]....
I've found very little info on how to reference a previous variable...maybe create an array to store them in, but wasn't sure how to go to the previous value in the array.
Dynamically Creating Variable Names
Aug 9, 2003Here's my problem: I need to create a variable name dynamically, made up of a string (say "var_name_") and an integer. Ultimately I want something like this:
var_name_1 = 'whatever value I want'
var_name_2 = 'whatever value I want'
var_name_3 = 'whatever value I want'
...
var_name_N = 'whatever value I want'
But the actual variable names are determined at run-time, so I can't just hardcode them.
Any suggestions? JavaScript doesn't seem to have a Variable type, so I can't just cast a string into a var...
Creating Anonymous Function With Variable?
Mar 20, 2010I'm having trouble with something that I can't explain outside of an example. Code:
Code:
$js_info_tabs = json_encode($valid_array);
$script = <<<JAVASCRIPT
<script type="text/javascript">//<![CDATA[
function changeTo(id) {
[Code]....
I have the code this way in order to consolidate it since I would prefer to do that instead of checking the selected ID and manually checking against all possible IDs (which works flawlessly, it just takes up about 5x the lines and is not modular). What I have above also works, but there is one fatal flaw:
It seems like the anonymous function that is the onclick for each unselected element becomes "return changeTo(tab + '_id')", but I don't want it to be that. I want the argument to actually be what tab is instead of the variable.
What ends up happening is that after changeTo() is called for the first time, any element you click will result in the last element being the selected one, as if it's using the final value of tab as its return value.
This doesn't make any sense, though, since tab is local, and deleting it before the function exists doesn't work. Deleting elem at the end of the for loop doesn't work. I honestly don't understand what's going on or why it doesn't set the new onclick value correctly.
Basically I just want changeTo(tab + '_id'); to turn into changeTo('MYID_id'); instead, but it simply doesn't do that and I can't figure out a way how.

Dynamically Creating A Unique Variable Name For Elements With Same Class Name?
Aug 31, 2010I am probably going about this all wrong, but I'm not sure how to do this.Basically I need to create a unique variable name for each element that has the same class name and set each one to zero.I thought I could just concatenate the index value to a variable name to create unique names. Something like:
$('.toggle-trigger').each(function(){
var toggleTriggerIndex = $('.toggle-trigger').index(this);
var t + toggleTriggerIndex = 0;

Creating And Writing Variable To Form Input Field
Apr 10, 2011I am working on a javascript for my blackberry. I am trying to capture the latitude and longitude of that phone. I am able to get the coordinates in an alert box but am having a little trouble writing it to a form input field.
<!DOCTYPE html PUBLIC
"-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html xmlns="[URL]" xml:lang="en" lang="en">

<script type="text/javascript">
if(blackberry.location.GPSSupported){
document.write("Your device supports GPS locating");
blackberry.location.onLocationUpdate(window.alert("Latitude: " + blackberry.location.latitude + " Longitude: " + blackberry.location.longitude));
var lat = blackberry.location.latitude();
var lng = blackberry.location.longitude();
blackberry.location.refreshLocation();
document.write(lat);
}
</script></body></html>
I am only able to test with Blackberry. I was trying to create a couple of variables with the "var lat =" and var lng =".
With this script I get the alert window and when I click ok it writes "Your device supports ...".
Get A Variable's Name As A String?
Mar 1, 2006I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}

I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?

Convert String To Variable Name?
May 11, 2011Say I had a bunch of elements with id names "id1", "id2". "id3" etc. Then say I had a function that adds a click handler such that when you click these elements it gets the id name with this.attributes[1].nodeValue;Then say I had a bunch of arrays with the same names as the ids var id1 = ["data", false, 45]; var id2 = ["otherdata", true, 15]; var id3 = ["otherotherdata", null, 65];. How would I set a variable "currentid" to the array with the corresponding name as the id name? I guess the underlying question is, how would I convert a string to a variable name?
View 1 Replies View RelatedConverting CSV To String Variable?
Aug 2, 2011I have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.
Getting Text String Into Variable?
Dec 28, 2010I'm having trouble getting a text string into a variable:
HTML Code:
<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml'>

[Code]...
I'm using the alert to confirm if I've managed to get the time ok from the html, it should when working display the static time but currently displays NaN which AFAIK means that javascript is getting something from the HTML but it's in a form that it can't work with.
I know that the HTML validates fine, the time display is output from PHP. The intention is that PHP will output the time, if javascript is available then the javascript will take the static time and turn it into a ticking clock.
I'll look into the main guts of the clock script at another time, right now I need to get the basics working. I need to do it something like this way as I don't want to have any javascript embeded in the HTML, I want to have the javascript in external files.
