Find Factors Of Number And Pick Two Closest To Middle?
Mar 10, 2011
Basically I want to factor a number and select the two closest numbers to the middle of the factors for example: 20 factors to 1, 2, 4, 5, 10, 20 I want it to return 4 and 5 If the number is has an odd number of factors (has to be a perfect square) I want it to select the middle number and say it twice for example:
64 factors to 1, 2, 4, 8, 16, 32, 64
I want it to return 8 and 8 Would I use an array or what? My code should probably look like:

I am trying to pick the larger of 5 numbers and sometimes there is a tie. I would like to prioritize variable c1 if there is a tie. This data is from a quiz I am writing.
var c1 = 2; // Takes priority if there is a tie.
var c2 = 1;
var c3 = 2;
var c4 = 0;
var c5 = 0;

I have a textarea with a specific width. I have wrap="off" set because I don't want to force my users to wrap if they don't want to. The reason for this is because this textarea is where the user is typing an email message. However I have a background image set on the textarea with a verticle line going down the textarea which indicates to the user the "Recommend Width"What I want to do is provide them with a link to click on which says something like "Wrap Lines" and when they click on it, the text within the textarea would wrap to the "Recommended Width" line in the background image. The maximum length of a line should be 53 characters when they click on "Wrap Lines" link.So I did some searching around and the code I came up with is:
Code:
function showLines(max, text) {
max--;
text = "" + text;
var temp = "";
var chcount = 0;
[Code].....

finding a "find on page" script that will display the results in the middle of the page for IE. I have tried several different ones to no avail. The ones that work in all the browsers display the result in IE at the very bottom of the page. I am not very familiar with programing in Java and I am unable to modify any for my needs. The one I found that did work in IE didn't work in any other browsers.

I need some help putting the factors of a number (y) into an array.For example if y = 20: [1, 2, 4, 5, 10, 20]Once I have this, I can use it to factor a quadratic:(ax = c)(bx = d)if c = 3 and d = 5 then I could check if 1c was a decimal, if 20d was a decimal and then vice versa.Basically, I can use these numbers to see if b or d is a whole number and if it isn't, try the next one.If none of them are, then I can do y(ax + c)(bx + d)

I am working on my assignment: The assignment is: The process of finding the largest value (i.e., the maximum of a group of values) is used frequently computer applications. Write a Javascript program that input a series of 10 single digit numbers as characters, determines the largest of the number and output XHTML text that displays the largest number. Your program should use 3 variables as follows:
a.) COUNTER: A counter to count to 10 (i.e. to keep track of how many number have been input and to determine when all 10 number have been processed). b.) NUMBER: The current digit input to the program.
c.) LARGEST: The largest number found so far.
Below is my code so far:

When I find a record such as this in a textarea:
[Code]....
There will be from 1 to 4 Pts, if one is missing there will not be a next one. My problem is I replace the first occurrence of any number I find and for certain factors (2 in this case) it could change an already converted number and leave other fields in the record alone. I could split the line on commas to change the first number I find but can't be certain if there are no other commas elsewhere on the line.

I need to find the average number in javascript. It is the only bit of javascript that I have to do in the course but it carries a high mark of which I cannot afford to lose. Any way the question is : "Write code to calculate the average height and write it out in the browser window"
<HEAD><TITLE> average</TITLE>
<SCRIPT LANGUAGE = "JavaScript">
//Experimental results of Table 1 stored in arrays.
var Height = [15,16,17,18,19];
var Number = [2,1,6,4,2];
//Part (ii).
//Write code to declare and initialise new array to represent the third row of the table.
var avg = new Array(5)
var avg = ["60","80","187","180","114"] ;
avg[0] = "60";
avg[1] = "80";
avg[2] = "187";
avg[3] = "180";
avg[4] = "114";
//Part (iv).
//Write code to calculate the average height and write it out in the browser window.
avg = 0;
for (var count = 1; count <= 5; count = count + 1)
Array.average = function(){
var avg = 0;
for(var a = 0; a < this.length; a++){
avg += this[a];
} return avg / this.length;
};
document.write('average height is ' +avg + '<br>');
</SCRIPT></HEAD><BODY>
</BODY></HTML>

Is there an efficient way (ie. not looping through all members and counting) to find out what number an li will get in an ordered list? For example: [code]...
Naturally #first and #second will be 1 and 2, respectively. Without looping though all children of ol and counting, can I determine the number for #first and #second?

I am having some difficulty in constructing a window.confirm() function that works with my code.So if the form data is valid, I need to use a window.confirm() dialog box to show the user's total cost based on the rental rate of equipment chosen and the reservation period. The user must accept the cost by pressing the confirm button, and if user cancels do not submit data.I have written this code but cannot figure out how to find the number of days from the 2 date fields and use that to calculate and display the total cost.
//confirm submit and display rental cost
var equip = document.forms[0].equipment.value
var pDate = document.forms[0].pickupDate.value[code].....

Been trying for about an hour to traverse the DOM to get the value of an input when the quantity is changed, total it and put it back. I have not been very successful unfortunately. erstanding of .closest() is that it will traverse up and find the first of whatever you're looking for. Below is the <ul> structure.
<ul>
<li>Type: Beverage</li>
<li>Price: $<input name="product_price" type="text" id="<?php echo $row['productID']; ?>" value="<?php echo $row['productPrice']; ?>" class="product_price" size="11" /></li>
[Code].....
Seems like it should be simple. I've worked on more complicated jquery stuff. Course my .parent(), .child() skills leave much to be desired..

I'm looking for an alternative for .closest(). My script refers to jQuery 1.3.2 which is not the latest, but does its job. By trying to implement my code into another script I noticed that this script uses jQuery 1.2.6. Well, 'changing that version was no option'.[code]This is my code. It should be used to clone special comments containing "In[" and in some cases "text".Unfortunately .closest() doesn't work out for me. i'm looking for an alternative.

I have the following code. Either of the statementsworks fine in IE8 but not in IE7.
var $parentTabId = $(this).closest("div.column").attr("tabindex");
var $parentTabId = $(this).parents("div.column").attr("tabindex");
I get "undefined" for $parentTabId in IE7. What is the alternative solution which works for both IE7 and IE8 ?

I am trying to figure out the syntax for the following. For this version I am simply trying to select the 2nd child of the SLIDE HOLDER div. For this test I am just making the width grow. My next pass will be to get the index of the DOT clicked and then pass it to the child of the other parent. Please see line 24. I know this is incorrect but placed it to give you an idea of what I am trying to accomplish.

I have the following script using the closet method. It works fine for the inner most li tags however the outer li tags don't get seen? So both Root 1 and Root 2 don't get selected but the Sub Cat 1 and Sub Cat 2 get selected fine. I'm sure I'm missing some code to make this work.

My HTML looks something like the following:
<label for="myTextBox">
Name:<span style="color:red;">*</span>
<input type="text" id="myTextBox"></input>
</label>
In my document ready I have a function which runs 'on blur' of the textbox and hides the span. The following code DOESN'T work to hide the span:
$('#myTextBox').closest('span').hide();
I'm currently using the code below which does work but was wondering why the above code doesn't....
$('#myTextBox').parent().children(':first').hide();

I'm new and naive at JS, but use a lot of modified JS snippets in web
design. I'm working on a six-language site for a client right now that has
a small nav bar at the bottom of each template-based page.
I've had success in previous projects, writing out language-specific nav-bar
code nested in a document.write statement; a unique .js file for each
language.
An idea that I came up with that would allow me to create a function that
would cover all languages was this: if javascript could somehow detect the
"lang" attribute of the <html> tag, it could automatically choose which
"langage" js file to reference for my nav bar.
Example, if my german nav bar was in a file, "/scripts/de.js" the function
would pick up "de" from the "lang" attrib in the <html> tag, assign it to a
variable, say "navlang", and render a document.write statement that would
"write" out my script source reference as such:
<script>
document.write('<script src="/scripts/' + navlang +'.js"></script>');
</script>
my problem is I'm not adept enough at JS to write a function that would grab
the LANG attrib of the page .

With html you can have a file input that browses for a file to upload.
As far as I can tell you have to pick a file and can't pick a folder.
Is there a way to pick a folder with JS. I don't want to upload, I just need the path.
