I tried and tried for so long to get this to work, but I just can't.
Here's what I did:
var testvar = document.getElementById('example').style.color;
alert(testvar);
Not only would the alert come up empty each time, but IE reports that "testvar" is undefined. Why isn't it working? And if I'm going about it the wrong way, how can I store an element's style info, such as font colour like in this example, as a variable?
I have the following javascript function:
<script type="text/javascript">
function HTMLEncode( text )
{
text = text.replace(/&/g, "&") ;
text = text.replace(/"/g, """) ;
text = text.replace(/</g, "<") ;
text = text.replace(/>/g, ">") ;
text = text.replace(/'/g, "'") ;
return text ;
}
</script>
Now i want to store the content of 'text' in a php string. Is that possible?
I'm working on a page that needs to do some calculations based on values that the user inputs via sliders. I can get the values selected to display in a text box below the slider, but I also need to store the value as a variable for use in calculations.

I was wondering if someone could help me on a problem I have been having. In my code my function is supposed to take the elements of the form and it checks to see if it is checked or not. After that it would store it in the variable checkbox. However when I test it out it will not store it in the variable. For example if I picked sleep/ standby checkbox and hit submit it will show as 06 instead of just 6. Don't know what I am doing wrong. Here is my [code]...

I need to write a script that parses a web page for a given delimiter and then stores the following 50 characters as a variable. I wrote the following php script:
Code:
<?php
$del = "picture_id";
$url = "http://xxxx.net/xxxxx/xxxxxx.php?do=xxxx";
$source = file_get_contents($url);
[Code]....
The delimiter is always going to be constant, however the succeeding characters will be different each and every time. I need to write this in Javascript because it is hosted on my server, and ran by users who post on my brothers message board (which is hosted elsewhere). Since Php is server side I always get "guest" as a value rather than the random string of characters like it should be.
I could use some help with a form I am trying to complete. If someone could PM me and I could attach the file. It's only a small problem but I am tired of spending hours trying to figure it out.
View 1 Replies View RelatedWhen a person signs up for my website it first adds them to my external email list and then to my MySQL database.In order to do this you have to pass the information of the form to the next page where you can "display" it. Nothing except this display function seems to work.So what I am trying to do is take what is outputted by this display button and store it in a javascript variable.

just a very basic question. Have a div (id - photos) with multiple images. 1) Does this select them all? $('#photos img') 2)If so, how can i capture this information? Like so -> var bunchOfStuff = ($('#photos img')); and 3) if so, why can't i do something like alert(bunchOfStuff.length)into code tags...

I kinda think that it has something to do with the escape quotation plus x, which I need so that the id won't duplicate.

I am trying to add some styling to the first word of all of my H2 headings.
Now obviously this would be very easy to do using a span, but let me clarify my situation.
I am working on a Joomla! site, so a lot of my code is read from php and sql files. I thus can't go and wrap my text in a span by hard coding it since it is dynamic and read from a database.
I thus decided that manipulating it using javascript will be the simplest. The only other chice is to write a php script that does pretty much the same thing, but I prefer javascript.
So here is what I am thinking of doing:
I want to select all of the H2 elements from my document, get access to their text content, single out the first word, and then wrap it in a span. The span will have a class, which will then simply be styled using CSS.
I though I was on a roll, but is seems that I have hit a snag. I am able to select and edit a single element with an id, but not all of the H2 elements in my document.
I was using 'getElementById' and assumed I could simply change it to 'selectElementByTagName' at some point.
I then used 'innerHTML' to retrieve and manipulate the contents.
Here is my code so far, and it work to some extent:
Code:
It seems though that 'innerHTML' does not work with 'selectElementByTagName', and I can't seem to find a similar command that does.
I also can't use ID's since I can't manipulate the HTML (at least not without scratching through a whole mess of php). Even then I need to manipulate various elements on one page, so ID's are no good anyway.
So my question finally is this: Is there a similar command I could use, or am I busy going in the wrong direction?
I've spent several days trying to work this out. Maybe I'm just
searching for the wrong keywords/phrases.
I have some code that looks like:
[-- snippet starts --]
Console = new Object();
Console.init = function() {
this.STDIN = document.getElementById('console0_stdin');
this.STDOUT = document.getElementById('console0_stdout');
// set styles on the element references, eg:
this.STDIN.style.width = ï`%'
this.STDOUT.style.width = ï`%'
}
Console.focus = function() {
this.STDIN.focus();
}
Console.writeln = function(buffer) {
this.STDOUT.value += "
" + buffer;
}
[-- snippet ends --]
I'm not sure why, but the Console.focus() and Console.writeln() methods
just don't seem to be able to use the DOM references stored in
Console.STDIN and Console.STDOUT. Everything's fine in the
constructor, but other methods can't seem to use them.
I am using javascript code to change the background colour and font colour of some elements called 'filled') dynamically. For example:
if(timeInputValue >= startcode && timeInputValue < endcode && stateInput.value == "playing") {
filled.style.backgroundColor = '#ffffff';
filled.style.color = '#000000';
}
I also want to put a border around these 'filled' elements too - how can I do this is javascript? I can't find an equivelent to style.border = "1px"
This is calculator program that I have gotten stuck on. Here is where I think I am at:
The program is now taking the 1st number entered displaying it and storing it in the variable "memory".
Operation (+,-,*,/) is added to the memory in function action1() but then when the second number is entered it replaces memory with the second number. How can I get the variable memory to the whole string of 1st number,action, 2nd number?
Also once I do get that working correctly:
Wouldn't eval(document.calculator.display.value= memory) in my HTML for the "=" give me the calculation. (if I could figure out how to have memory store the 1st number and action1 and 2nd number all together) Or would eval(document.calculator.display.value) do it for me.

How do I do this? I've set up javascript to change the background colour depending on what colour square the user clicks on, this is working fine.However, I want to be able to set an initial colour, other than white, and then let the user chose their own.
here is my code so far.
<script language="JavaScript">

function changeBGC(color){

I want the page to be initially set to the brown colour, then I want the user to be able to choose their own colour.
I'm trying unsuccessfully to get some text links to change & restore their colour.

Referencing this link - there are 3 text links at the top of the page, which scroll to different anchor points on the same page.I need the following to happen: On hover, change colour (easy using css) On click link A, change colour When clicking link B, link A restores to original colour.

To get value of element by id from document is very easy:
var example = document.getElementById('myId');
But what if I would like to get value by id from variable:
var example1 = '<a href="example.html" id="myId">lorem ipsum</a>'
Is there any way?
Is it possible to use variables as the name for a form element e.g.
<script type="text/Javascript">
<html>
<head>
<script type="text/Javascript">
var myvar = 1;
</script>
</head>
<body>
<input name="myvar" type="radio" value="radiobutton" />test
</body>
</html>
I tested the above and looked at the course. The name is shown as "myvar" and not "1", so I guess it didn't work.
I have several lines of code in different functions where I need to refer to elements in document.form.max, so I figured I would define it as a global variable called tb1 to shorten the writing. The result however is the page senses an error as soon as it gets to tb1.value, of which I can't figure out why since things work when I change tb1 into a local variable. I was under the impression that global = full scope, so I'm not sure what's wrong here.[code]...

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.
I'm just trying to output a value, but whenever it gets to "var max = tb1.value;" it stops working. I can't find out what's wrong with my [code]....

The bolded line is the part which isn't working.
I have a variable that contains Form Elements. So these elements can be eitther a :text either a :check box See code below:
var currentValue = $(targetedInput).val() ? currentValue = $(targetedInput).val() : currentValue =$(targetedInput).is(':checked')
I was hopping that this line of code would assign a different value to currentValue depending on what kind of object i have. My idea was that If the current Object is a check bot it doesn t have a val attribute..
