How can you join two numbers together in javascript, like you would join two strings?For example, if you have two variables, with 1 stored in each, how can I join them together, so I get 11, instead of 2?
View 2 RepliesI don't understand ..
$("#form-dialog-join").dialog() is a valid function which I copied from Jquery demo. What's wrong with it?
btw, all the jquery library is loaded correctly.
What the join() method really does... I didn't quite get it. It said that it joins the array elements into a string, but isn't it already strings? how would you use this method...
var fruits = ["banana", "apple", "pear"];
document.write(fruits.join());
What did that do, how do use this method.
I would like to go to a url based on what the user selects from three seperate pull down menus.
Example user selects a product. Then selects a month and Selects a year.
month and year would join together Then create a path
<a href="product/month_year/DEFAULT.HTM">
I this possible with javascript.
I have two element sets: $(".contentBox") and $(".referencesImage"). How can I join the elements in this sets? I would like to join the sets, since I'm adding the exact same hover function on both element

i want an html code or javascript equivalent for this particular case.i want to put two input values into one.in other words, join them together..example:
<input name="name" value="William"/>
<input name="surname" value="Shakespeare"/>
and then the next input would be the the combination of the first two input .example:
input name="completename" value="(name + surname)"
to yield and input value of value="William Shakespeare"
I am working on a project which requires a method to join or split multidimensional arrays according to its arguments, which would be string delimiters for the various dimensions of the array.
An example of the join function might be:
The split function:
This would turn 'str' into an array like this:
I think I may have found the problem (but not the solution) - it looks as though javascript won't perform a method on an array which is part of another array. Firefox error console gives me "arr[0].join is not a function".
what i'm trying to do is have it when once a user clicks on a banner the join raffle button will show after clicking on the banner, along with opening up a new window to the link the banner had. I've been trying to set up a onclick event to do this but haven't had success This is the code ive tried using.

I need to capitalize user input from a text field by passing the data to an array and using the split() method, then then join() method and of course toUpperCase. I need to accomplish this with a loop. I only have a crappy ebook and haven't ever been in a java classroom.
Here's what I have which is not at all sufficient. I learn best from examples, so here I am...
<HTML><HEAD>
</HEAD><BODY>
<FORM ACTION="#" NAME=strn>
Enter lower case text
<INPUT TYPE=TEXT NAME="txt1" SIZE=20>
/
The following lines of code are just my attempts at guessing javascript logic/syntax
function arrays(){
for (var i=0; i<secondarray.length; ++i)}
firstarray=getElementByName.txt1
var secondarray =firstarray.split(separator[" ", 40]).toUpperCase();
/var secondarray.join([""])
<BR><BR>
<INPUT TYPE=BUTTON VALUE="Convert to Upper Case"
onclick="document.strn.txt2.value = document.strn.txt1.value.toUpperCase()"
<BR><BR>
<input type = "text" NAME=txt2 size=20/>
</FORM></BODY></HTML>
I know this much .array = string.split(separator[, limit]);.
I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?
The code at the above URL is as follows:
<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";
</script>
[Code].....
I'm a relative novice at java script. I've been working on a google map that can be found at: [URL](way too much code to post here). Each of the makers on the map has s particular set of information that pops up in a window when it is clicked, including a hyperlink called "join this group." Right now clicking on that link merely takes the user to the form at the bottom of the page.
What I would like the link to do is to both take the user to form at the bottom of the page and automatically select from the drop down menu the group associated with that particular "join this group" link. For example, if a user selected the marker representing the Neighborhood, Beverly group and then hit the join this group link, the drop down menu would automatically select the Neighborhood, Beverly (Pless) for them. I suspect this involves using java script to pass a value. I just have had no luck getting it to work.
I am writing a script and everything works fine, except when I calculate my figure i want to display only 2 decimal points.
ie. 10 = 10.00
ie. 10.56789 = 10.56
I have no idea on how to do this and I cannot use Cold Fusion.
Is there a built in JS Function?
I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?
How do I find the row & column number of the table for a checkbox on

Code:

Now what my question is how can I get the spinner to only allow numbers to be inputted in the spinner and not letters. Also how can I get it to only allow 2 digits to be entered in the spinner?. I know it will require an if statement but I don't know how to do it.

View 3 Replies View RelatedAnother quick question. I have the script to add each field up I need, but if the ending 0 after a decimal is present it doesnt show. How do I keep the leading zero and how do I keep just 2 digits after the decimal?
For example:
1 + 1.50 = 2.50
But javascript displays it as 2.5
Now sometimes when I do math I get:
2.3454545
In this case I just want 2.34. So if there is a ending zero I want to keep it, and if there is more than 2 numbers after the decimal I want to cut the rest off and leave the 2 there.
iw ant to have a function so that user can only enter numbers in the text box and + ( only once in the beggininging). if user wants to add + he can only enter + once as the first character like +123 or 123 bt cannot enter 1+2 or 123+ or +123+
