Passing Data From Prompt To Function Assistance?
Feb 7, 2009
I'm trying to pass data I gathered from a prompt into a later function.
1. Should prompts for information be in their own JS file separate from the HTML page? Or is it better form to have the prompts (for info) in the HTML page itself?
2. I have tried placing the prompts to gather info in several places, each time my script seems to stop after the data is gathered and does not perform the calculations which are contained within a function. The input data is gathered from a prompt, do I still need to "return valuea" and "return valueb" in order to use the input data in the calculation function? Initially I did not feel I did, as I am not performing a calculation initially, just receiving input.

My validate() function is not working quite right since it should validate for at least on checkbox checked and even if opne is checked it will simply display the error message instead of validating. What might be wrong here?
Here's the function (note, all the checkboxes have the id='chk')
function validate(){
var countChecks = 0;
if (document.forms.getElementById == "chk")
{
for (var j in document.forms.getElementById)
if (j.checked)
countChecks++;
}
if (!countChecks)
{
alert('Select some checkboxes!')
return false;
}}

I should warn, i know almost nothing about javascript. i've been trying read sample scripts and examples on how to modify this script; but I just don't know enough. I have a script that pulls data from an array, and copies it directly to the clipboard when a user clicks on it. The problem is this only works in IE, because Firefox doesn't by default allow that to happen. I'm trying to change it so that when it is clicked, instead, it takes what was going to be copied to the clipboard, and puts it in a Prompt box for the user to copy and paste. I had other scripts that do that, but I can't for the life of me figure out how to learn from it!

I have two prompt dialogue boxes that ask the user the enter their name and their employee number.I am experiencing two errors. The first is, if a user enters their name incorrectly, using numbers for example, there is an error message that asks the user to re-enter their name using a string. If the user ignores the error message and enters a number a second time, the program accepts the entry, which it shouldn't.
The second error has to do with the employee number prompt. The prompt asks the user to enter an employee number that is equal to 6 digits, the program however accepts any number, less than or greater than 6 digits, which it shouldn't.I don't want the user to get away with entering anything incorrectly.
<script type="text/javascript">
// prompt the employer the enter the employee name and number
var employName = prompt ("Please enter the employees' name" , " ");[code].....

I have an assignment where one piece of it needs to have the first name, last name, area code, and phone number when prompted by a function, once that info is had, it then needs to use the constructor function that is there to process the data and lastly use the data to output it with a show function. I have it to work with static information, but cant seem to figure what I am missing or how to make the prompt function information to feed to the constructor, I know when using the static variable it uses "new Function" but that seems to be my problem,code below:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

This is my code and I have figured it to create an array from the prompt and then use the function to return the first array it finds but I cant seem to make it go on to the next index of the array. I know that when you return a value the function closes and I have tried to store my return in a variable but its not working the way I want it to or I'm not writing the correct command or is there away to do multiply returns, I think what I need to do is simply but I have been staring at this screen for a while now and just cant see it.

I am by no means a JS programmer, but I like to exhaust all avenues when attacking an issue. A signature fired off on a piece of javascript that came across the wire, with an odd "var unescape" inside of it. I am hoping to throw this code out there, to see if anyone has any insight on what this might be.
I am assuming this is double encoded, but I am not certain. Here is the snippet of code the signature fired off from:
var ibdf=unescape("%u0b0b%u0b0"+"b");
var fdofdopf="xcvb9090";

Does the world need another DHTML popup calendar? Probably not, but I'm writing one anyway. It's unique in that it allows drag selection of a range of dates. Works great on IE6 but I'm having some trouble with Netscape and events. In particular, the mousedown event doesn't work. The event fires, but I can't seem to get a handle on what html element was clicked.

What I'm trying to do here should be simple and I suspect that I'm just overlooking something basic but I'm overlooking it. If you can tell me what I'm not seeing here, I'll be most grateful. This is the associated HTML code. Two statements to be rated from 1 to 10 using radio buttons.
<tr>
<td width="25"><strong>A</strong></td>
<td width="210">A statement is here</td>
<td width="21"><input type="radio" name="SI_QA" id="SI_QA_1" value="1" /></td>
(total of 10 lines like this)

1) To populate a dropdown control that's on a page with data coming
from the database, the developers concatenate all the values separated
by a pipe character and pass the string to the JS function, which
splits the string and adds the values to the dropdown control.
I think this is not a best practice b/c:
A) If the data returned from the database results in a string that's
too long, it could exceed the limit of the JS string type and some
items would be missing from the dropdown.
B) If by any chance, the data from the database contain pipe
character, it would result in extra elements inserted in the dropdown
control.
Is there a better way to pass data to JS w/o relying in strings? How
can these practices be improved?

I am working on an application in which monthly calendars of events are to be generated. When the page is initially loaded, the current month's calendar is generated using Javascript; the user can also move forward to the next month or backward. For each month, I need to be able to retrieve server-side data (using PHP/MySQL) to fill each day-cell ("td"+i, below) of the calendar with events for that day which reside in the server-side database, keyed by date. Here is a snippet of the code that generates the days of a given month:
var d = 1;
for (i = 0; i < 42; i++) {
var elem;
var elem = eval(document.getElementById("td"+i)); //the day cell
elem.innerHTML = "";
if (i >= startingPos && i < lastpos){
elem.innerHTML = d
d += 1;
.
.
return;
In short, I need to get data from the database as the days are created (elem.innerHTML = d, above) or get all the data for the chosen month (probably more efficient), and send it back to the Javascript where it can be parsed and loaded to the appropriate cell(s) in the calendar.

I am using a variation of this script so that on the homepage of my site, a person can enter their phone number and the data from that form is tranfered onto a form on a second page for the rest of their other data as well as autofilling in their phone number data they entered on the first page.
The output for the code is:
Code:
<SCRIPT LANGUAGE="JavaScript">
areacode = unescape(params["areacode"]);
document.write("areacode = " + areacode + "<br>");
</script>

EBay has implemented a different way to upload auction pictures ---
after browsing for the picture and selecting it, the image preview
instantly displays on the screen, which is nice. Apparently this
process is being handled locally --- could someone try to re-create
this ? ... I imagine its using DHTML or some other technique, I'm not
sure how I would code this.

I'm trying to communicate between a parent document that is controlled
through pure Javascript with an embedded IFrame containing an ASP.NET
form. I can quite easily pass data into hidden fields in the IFrame and
submit the form to pass data to the ASP.NET application.
Now the tricky part! (at least for me, probably not for everyone
else!), how can I set a field in the ASP.NET page (using ASP.NET during
a postback), which I can get the value of within the parent Javascript
controlled page?

I am using jqueryUI dialog, and want to pass some data to it. data() seems the best method, right? The following works. $(".delete").click(function(){$("#dialog-delete").data('row','Hello').dialog("open");}); Now instead of just passing a single value, I want to pass an element. I tried the following, but am obviously doing something wrong. $(".delete").click(function(){$("#dialog- elete").data('row',$(this).parent()).dialog("open");});
