Function That Compares 2 Alpha-numeric Values?
Jul 23, 2005Does anyone have a code snippet to compare those values so I can sort
the array of alpha-numeric values that include both characters and
integers in it?
I.e., if we have values like 4236 and 123234, I want 4236 to be second
because 4 is bigger than 1 rather than using the numeric comparison.
The strings can include character values and strings. Basically, I have
the bubble sort function, the question is how to compare those types of
strings in the alpha-numeric order.
i.e.,
A83745
B34974
127734
34456
788
I looked all over the web thinking that this simple question would be
answered somewhere, but could not find the answer.
Correct Parsing Of Strings For Numeric Values
Feb 12, 2009I'm currently working on a web page that's acting much like a spreadsheet. There are fields that the user must fill in and then certain columns of fields add up to a sum at the bottom. I haven't been able to get it working quite right.
Here is the essence of the code
Code:
<form name="drillreport" method="post" action="process_report.php">
<table><tr>
<td> Field 1 </td>
<td> <input type="text" name="field1" id="field1" onBlur= calcTotal() /> </td>
</tr><tr><td> Field 2 </td>
<td> <input type="text" name="field2" id="field2" onBlur= calcTotal() /> </td>
</tr><tr><td> Field 3 </td>
<td> <input type="text" name="field3" id="field3" onBlur= calcTotal() /> </td>
</tr><tr><td> Total </td>
<td> <input type="text" name="tot_col" id="tot_col" onFocus= calcTotal() /> </td>
</tr></table>
...
It is more than that of course, but you get the idea.
The function I wrote is the following:
Code:
<script type="text/javascript">
function calcTotal() {
var returned_val=0;
returned_val += parseFloat(document.drillreport.field1.value);
returned_val += parseFloat(document.drillreport.field2.value);
returned_val += parseFloat(document.drillreport.field3.value);
document.drillreport.tot_col.value = returned_val;
}
</script>
I use the onBlur for each of the "component fields" so that if the user changes one of the fields, it updates the total. However, I can't get this to return values properly when just field1 is entered ( NaN ) comes up. As soon as I enter the second column the total appears fine. Why wont this work if you just enter the first field?
Validation - Compare Two Textfield Values (numeric) And Warn When One Is Larger?
Feb 18, 2010I'm struggling to get what I want to work..I have two textfields (using jquery to ensure digits only, limit 3) one is total_available one is currently_available
obviously you cannot have more things available than you have in total, so i need to compare them, and warn when the second one is larger than the first. I tried to modify the jquery validation equalTo with no luck.
i actualy dont care it its not, if i can get the values from the fields, convert them to INT, then compare, and change the innerHTML of a warning DIV that is next to the fields to say "check again" then it will be sorted.

Once Set A Private Variable, Test That Object Independently Becomes A Nightmare As The Next Test Is Polluted By The Actions Of The Previous?
Mar 14, 2009I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).

Generate An Array Of Integers?
May 26, 2010I am implementing several scriptaculous sliders in my app... and one thing I can see being an issue is setting their "values" property to limit the selectable values.
This property takes an array of integers representing the allowable values. Unfortunately without this property, the slider will allow you to select a decimal value, so I can't just use a min and max if I only want integer values output.
Creating an array for a small data set is simple: for example "values: [0, 1, 2, 3, 4, 5]"
But some of my sliders will range into the hundreds and need an array of hundreds of allowable values. Is there a simple way to generate an array of 0 to 100 integer values (or more). I know I could use a for loop but it seems to me there might be an even easier way, though I cannot find it.
I would like it to fit in a code block like this:
javascript Code:
var s1 = new Control.Slider('handle1',
'track1',
{
axis:'horizontal',
[Code]....
EDIT: for further clarification, I found that PHP has a range() function that does exactly what I want. Anything comparable in Javascript? [URL]

JQuery :: Playing Arround With Integers?

Calculating Sum And Average Of Integers And Display Value
May 25, 2009I'm a newbie to javascript and I made this script
<script>
var num = parseInt(prompt("Enter the number of integers to follow"));
var sum = 0;
for (i = 0; i < num; i++){
sum += parseInt(prompt("Enter a number"));
}
if (isNaN(num)) {
alert("Invalid");
} else {
if (sum < 0) {
document.writeln("The sum is 0 and the average is 0");
} else {
document.writeln("The sum is " + sum + " and the average is " + sum/num);
}
}
</script>
The scenario : Create in javascript that will read a series of integers at the terminal. The first integer is special, as it indicates how many more integers will follow. Your javascript is to calculate the sum and average of the integers, excluding the first integer, and display these values to the screen. If the total is not greater than 0 then display "The sum is 0 and the average is 0". Did I write the script correctly? am I missing anything that a dumb person might do? for example the person might type in letters instead of numbers.

Numeric Validation
Oct 2, 2006I am modifying a java script that has a function to validate a numeric value. I am attempting to update this function to validate numeric ranges for example =>0 to 35000.

Numeric Date Validation
Jul 23, 2005It has appeared that ancient sources give a method for Numeric Date
Validation that involves numerous tests to determine month length;
versions are often posted by incomers here. That sort of code seems
unnecessarily long.
For some while, the following approach has been given here :-
function ValidDate(y, m, d) { // m = 0..11 ; y m d integers, y!=0
with (new Date(y, m, d))
return (getMonth()==m && getDate()==d) }
and it may remain the shortest code. But it does require, in every
case, the creation and disposal of a Date Object.
The following is about 50% longer in code, but about four times faster
in my system - and it seems to be right, too.
function DateOK(Y, M, D) {
return D>0 && (D<=[,31,28,31,30,31,30,31,31,30,31,30,31][M] ||
D==29 && M==2 && Y%4==0 && (Y%100>0 || Y%400==0) ) }
Note that checking for 1 <= M <= 12 is inherent, and that the Leapness
of the year is only determined if the date given is February 29th.
Also, it is easy to use only the quadrennial rule if it is certain that
dates are in 1901-2099, or only two rules for 2001-2399.
