Accept Two Numbers From A User And Will Determine Whether The Second Number Is A Factor Of The First
Oct 23, 2011
I have been presented with: Draw a flowchart and write a javascript program which will accept two numbers from a user and will determine whether the second number is a factor of the first. This is determined by dividing the first number by the second and checking if the remainder is 0. This is made easier if you find out what the operator does. The output should be in the form 4 is not a factor of 6 and 3 is a factor of 6. I have tried a few attemps and yet still not sure what the problem is :confused:
provide the HTML/Javascript to ensure a field can only accept numbers? (I don't mean post-submit validation, but literally the field only accepts numerical input.)
I have searched the internet and couldn't find a problem regarding this issue. The thing I want to do is simply validate a text input so when you enter a number in it, it won't validate and give you an error message. This is the code:
I have a JS function which checks whether the directory field value entered starts with an alphabet or number only. Following is the code using regular expression.
function testpw() { var un = document.getElementById("dir").value; if (/^[^A-Za-z0-9]/.test(un)) { // only a-z0-9 allowed as first character
[code]......
method which only accepts "/ktp/knas/" as the starting value and anything after that. ie it should accept /ktp/knas/*, rest everything is not accepted.
I need to restrict a range of values to a textbox. I have already the minimum and maximum value allowed in the textbox, but is missing me intermediate values.
An example: From the minimum value -2,00 to maximum value 0,00 it accepts: -2,00 | -1,75 | -1,50 | -1,25 | -1,00 | -0,75 | -0,5 | -0,25 | 0,00 From the minimum value 0,00 to maximum value 1,00 it accepts: 0,00 | 0,25 | 0,50 | 0,75 | 1,00
If I had a webpage that displayed a database in tabular form, it would be nice to know how many lines of text the browser could display without scrolling, then have the cgi script output the appropriate number of lines of data to fill the screen.
I've seen examples of how to get the browser window size in pixels, but is there a way to determine the number of lines that are displayed?
I have searched Datepicker, the forums and the internet in general to find the way to determine the number of days between two dates using Datepicker. My inputs are named: Starts, Ends, Days. I found the code below, but cannot get it to work.
// calculates reservation duration function resDuration(#Starts, #Ends) { var date1 = new Date(#Starts.value); var date2 = new Date(#Ends.value); var minutes = 1000*60; var hours = minutes*60; var days = hours*24; var diff = Math.abs(date2.getTime() - date1.getTime()); return round(diff / days); } /* put that value in elapsed days field */ $('#Days').val(diff); I will then do validation on the result - input field "Days".
I am trying to pass the slection made by a user to a javscript function using the onchange event. The problem is I can get the index but not the actual value. As my list is variable (dependent on a db) I cannot hard code to a static index. I either need a way to determine the number of items in a select control or a way to determine the actual selection made by the user.
Can anyone enlighten me as to the code to determine what option the user selects?
I have this script that is supposed to check if a number the user guesses is the same as the randomly generated number.Problem is that the random number generated at the start of the program keeps on changing everytime I click on the "Check if I'm right" button, the random number gets generated again and I never ever get to reach the correct answer

I need the code for if the user enters in a code into the field for example E1 and clicks submit it'll redirect them to a certain form. And if another user entered in E2 it would redirect them to a DIFFERENT form.
While using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality myself and wanted to share it with the group.
1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:
var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.
2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:
I have what I thought was a fairly simple problem that I would be able to solve on my own, but the code I have found is just too complicated for me to understandI think what i have is similar to the knapsack problem, but I have a really simple version of/~moshe/recor/knapsack/knapsack.html#defSay I have a relatively small array of numbers:2, 2, 3, 3, 4, 4, 5, 5, 5, 6, 7, 8, 9, 10. I just need to verify true or false if a combination of these numbers will add up to 21. The numbers will obviously be changing, ( and in array size), i guess i could just use if statements but it would be stupid and go on for ages.Could anyone point me in the direction of some simple code, or easy to understand way to go about this problem?
I want to build a web form that will allow users to enter 3 different numbers and get a result. The answer is arrived at by the following. Enter 3 variable A, B, and C. Then A / B = D. Then C / D = the Answer.Is there a way to set that up as a single click script? Everything I have tried has failed hard.:mad:
have a form with three fields for home phone, work phone & mobile phone.I've got jquery to validate that the numbers entered are the right format, i.e. using the following with custom methods for the phoneUK etc.The thing is I only need one of these numbers. I have been trying *all day* to try and get this to work but no joy. I know I need to group them somehow but can't figure it out.I want it so I get a single message if all fields are left empty and then if a field does have an entry then it's validated to ensure its a number.
I have a list of sequential numbers here. How can i show the 5 numbers infront and behind a clicked number?e.g. When i clicked on the number 0, this is the situation:5 4 3 2 1 0 -1 -2 -3 -4 -5So when i clicked on the number 2, it should show like this:7 6 5 4 3 2 1 0 -1 -2 -3
I am trying to allow the user to type in two numbers and then a multiplication table pops up below it. how to make the first row be 0,1,2,3,4,5..ect and same for the first column in each row going down the table. Here is my code..
I'm trying to create a 4 x 4 array filled with numbers input by the user. I then need to rotate the grid clockwise like I've shown below.
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16
13 09 05 01 14 10 06 02 15 11 07 03 16 12 08 04
I made all numbers double digit just for show in the example so the table is easier to read. So far the code I have is just trying to create the array and fill with numbers from the user. This asks for a number once then doesn't display anything at all.
I need to write a program that asks for 3 different numbers (prompt boxes) and determine which number entered was the highest and the 2nd highest. I know what to do for the input and output but I don't know what to do during the processing.
Create a function that prompts user for a number. Develop the program so that it continues to prompt until it receives valid information. Then create a multiplication table that displays the number multiplied by 1 through prompted number.
