Representing [ And ] Characters In Function

Oct 17, 2007

i have checkbox to call function

<INPUT TYPE = "checkbox" NAME = "AttributeValue[1]" VALUE = "Yes"

The function itself has this:

if (form.AttributeValue[1].checked) {

(more script) }

That doesn't work because I believe it is interpreting the [ ] characters
as representing array (I think).

How is syntax for AttributeValue[1] as literal value in function?

Does this make sense?

Onkeyup - Some Buttons Representing Letters And A Textbox - When Clicked - Its Value Is Copied Into The Text Box

Dec 8, 2009

I currently have some buttons representing letters and a textbox. When a button is clicked, its value is copied into the text box. I have an onkeyup event which means that every time a button is clicked, a function is called which searches some arrays using the current text box value.

However, the problem I am currently having is that the onkeyup event which calls the function works if I type the value in using my computer keyboard, but not when using the buttons (even though the buttons enter values into the textbox).

How I can make it so that when I press a button, the onkeyup event triggers and the function is called?

JQuery :: Dynamically Declaring Functions - 'array' Variable Contains Strings Representing The Id's Of Different Elements

Oct 12, 2010

Demonstration code:

The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.

Too Many Characters In A JavaScript Function?

Nov 19, 2007

In IE, it looks like you can have to many characters in a javascript function.

The content of an entire html page is put into this function...

function updateTemplate(content) {
content=content.replace(/'/g, ''');
content=content.replace(/"/g, '"');
content=content.replace(/&lt;/g, '<');
content=content.replace(/&gt;/g, '>');
Element.update('template',content);
}
it seems to cut off the content after about 2060 characters. is that an IE thing or is there something wrong with my code. FF does it fine...

If it is an IE thing, is there anyway around it?

Unicode Characters

Aug 2, 2007

Problem:

Depending on an input value, I would like to output greek characters
(f. e. those between U+03B1 to U+03C9. One way would be to define two
arrays: one with the possible input values ("abgde...") and a second
array with the corresponding values ("u03b1u03b2u03b3...").

But I hoped I could skip the second by a computation, f.e. "g" has
index 2 in the first array, so output "u03b1"+2.

This does not work (of course). But do I have a chance to "compute"
the output value?

Getting Div Width In Characters

Nov 18, 2005

I have a bordered div with some text in it. Some of the text is one long string and thus runs outside of the div. The div stretches out to the width of the browser window so that long string of text runs all the way out past the edge of the scrollbar.

Is there a way I can use JavaScript to detect the width of the div from the edge of one border to the next and then convert that number into the number of characters that can fill that width?

Replacing Characters

Mar 6, 2006

I have a script which gathers information from a form and, if needed, writes this info to a 'preview' window. At times {tokens} are used in place of real html tags. How can I tell the script to look for "{" and "}" and replace them, respectively, with "<" and ">".

I tried using "str = str.replace(/{/g, "<").replace(/}/g, ">");" but that didn't work. The script in question is being written by PHP... thus, may be generating a syntax-based failure. Any ideas?

Do Not Allow Certain Characters In Text Box?

Limiting Characters In A Text Box

Jul 23, 2005

I have a input filed of type "textbox" into which I am expecting to get
currency values (ie. 199.99). Is there a way that I can restrict the
user to only entering 2 values after the decimal point?

I can restrict the maxlength to 5, but that wouldn't stop the user from
type in 1.987.

Showing Illegal Characters

Jul 23, 2005

I am building a web page to show a TCP/IP raw packet.

I need to show "special characters" on the web page I am working on.
When I say "special characters" i am talking about tabs, whitespace,
crazy unicode characters, etc etc.

What is the best way to present this to the user?

I am thinking that a large textarea is the only way to display it so it
retains all the special characters.

Displaying Special Characters In A <div>

Jul 20, 2005

I have a problem displaying a divbox containing a html-textarea -
everything works fine with "normal" characters. However, when the
textarea contains special chars like <P> or ' , the box fails to show:

function show(divbox)
{
divbox.style.display=''
}

<div id="divbox" style="display:none" >
<form action="action.php" method="post>
<textarea name ="txt">Text</textarea>
</form>
</div>

If the Text in the textarea is for instance
HERE IS A "QUOTE"

it works fine, while
HERE IS A 'QUOTE'
produces an error

<br>-tags works fine, but
<p>-tags doesn't

Treating Special Characters

Jul 20, 2005

I have a number of scripts that take special characters and convert them
to their ascii equivalents and them store them in the database.

However I am running into a problem that I have some of those fields are
loaded to an array and inserted into cells dynamically. As an example
the array would be:

var my_array = [ ["52","Source Data"], ["19","Body &amp;
Soap"] ];

Then I have some javascript that creates the cell and inserts the value
into a cell text node like:

var x = my_array[1][1]; // this would be "Body &amp; Soap"

//create the cell
myTD=document.createElement("TD");

//create the text node
myText=document.createTextNode(x);

// Appends each node following the structure.
myTD.appendChild(myText);

What I see on the output is: "Body &amp; Soap"

What I should see is: "Body & Soap"

Anyone know how to get around this?

Removing Unwanted Characters

Jul 20, 2005

In a web based form I am able to make sure that there is text in an input field but I want to restrict the user from using such characters as ~ # & '

How can I modify this JavaScript below to enable this ?

if (document.form1.ProjectTitle.value == ""){
alert("Please complete the Project Title: field")
document.form1.ProjectTitle.focus()
validFlag = false
return validFlag
}

When entering the project title into another system it issues an error when those characters are input - hence the need to delete them from the request.

Count The Number Of Characters

Feb 24, 2009

I want to count the characters in a string. The problem here is, the 'return key' i.e if 'enter key' should be counted as 2 instead as 1 character.

I tried few logics but none of them worked out. I tried with php ajax too. It worked fine in firefox but not in IE.

Here is the logic i used. When onkeyup call the js function.. which calls the php page by passing the string as encodeURIComponent(str).

Now, I took the string in php and counted the in the string and added the no of occurrence of to the string length.

My concern is, IE is returning 3 for return key instead of 2.
