Merge 2 Arrays	View Content

Hi,

I am trying to merge the values of 2 arrays.

array 1 = 1, 2, 3, 4, 5

array 2 = a, b, c, d, e

Resulting in:

array 3 = 1-a, 2-b, 3-c, 4-d, 5-e etc

both arrays that will be used originally will always of the same length. Both arrays will contain numbers

Can you please help?

Thanks

Creating Arrays Dynamically, Need Help Looping An Array To Make Arrays. : (

I need to loop the alphabet and numbers 0-9 to initialize a few thousand arrays.
This is for my site and is truly needed. http://www.thefreemenu.com
I currently have every array written out and it takes up to much space in my .js file.
The majority of my variables are empty but necessary and need to be there (including empty) for my site to work properly.

Question is the last part

Here's where I'm at.

Code:

var NewVarLetterOrNum = "a";
eval("_oneofseveralnames_" + NewVarLetterOrNum + "='this part works';");
alert(_oneofseveralnames_a);

This creates the variable _oneofseveralnames_a='this part works'

Code:

var newArrayLetterOrNum = "a";
eval("_oneofseveralnames_" + newArrayLetterOrNum + "= new Array();"); 
alert(_oneofseveralnames_a)

This creates the Array _oneofseveralnames_a=new Array(); and all the values in the array are null,
but, now a variable like _nl_a[1]='something' can be used elsewhere because the array exists. This is all that is necessary for now
because I can probably set all the variables to be blank with something like

Code:

i=1
while(i<=20){
_oneofseveralnames_a[i]="1-20";
i++
}
alert(_oneofseveralnames_[20]);

So now you have what I came to understand in the first few hours. Now to the hard part : (

I can't make multiple array's dynamically. I dont' know if its because I don't understand loops or arrays or what and its very fustrating. As for any answer you might be so kind as to provide, if you could dumb it down that would be greatly appreciated.
Code:

var newArray =new Array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z')    
i=1
while(i<=26){
	eval("_nl_" + newArray[i] + "= new Array();");
	i++
}
alert(newArray[1]) // Is b, but
alert(_nl_b) //I can't get _nl_b to exist, I tried everything including taking away the quotes around the letters in every test

*/
var _nl_a =new Array()
var _img_a =new Array()
var _h_a =new Array()
var _r_a =new Array()
var _m_a =new Array()
var _yt_a =new Array()
var _i_a =new Array()

The above arrays are all the array _name_ parts I need but for example, a has 10 parts, a,p2_a,p3_a,.. p10_a. I need 10 pages for each letter of the alphabet and numbers 0-9 and a special all1, p2_all1 ... p10_all1. Overall 2200 arrays that need to be declared. Currently they are all written out.

Is it possible to merge the following?

Code:

document.getElementById("dimensionstext").style.color = "silver";

not sure I understand the concept behind merging two arrays together. I know that I have to make a deep copy of each array before applying the function. I know that I have to create a temp value to store the information in the arrays while I insert, but not sure how to keep in numeric order. array 1 = [3, 7, 12, 15, 22, 45, 56] and array 2 = [1, 2, 5, 17, 20] What simple code could I start with to create this.

Help With Simple Javascript 'merge' Script

Similar Tutorials

I'm trying to built a simple Javascript page that will serve the purpose of merging the values inputted into a form, and then using concatenation to merge these values in with other text to form several lines of commands that would be entered into a router to perform some task.

So in other words, it's just a "Merge" script.

I should mention that I'm just starting to learn Javascript. I actually haven't been finding Javascript as easy as I thought it would be to learn, and I think it's because there are several ways to do the same thing and I wouldn't be surprised if my problem is I'm using two different methods here...or just using the completely wrong method....

I've seen examples of using 'for' loops and arrays in forms, and I still can't get my head around that. If possible for now I just wish to call in the values and concatenate them, but maybe I do need a loop I don't know

Anyway, at this point, my only wish is to be able to get the script to concatenate the values, and then later I'll add the rest of the text it will merge in with and have it write to the page instead of the console.

So here is what I have right now. It only partially works (I'm only writing to the console in FireFox at the moment to debug while I test, so that is why you see console.log instead of document.write or whatever.

There are 4 fields in the form, and for example, if I enter in each field one word:

This
is
a
test

The ONLY result I get when submitting the form is the word "This". Then the form is cleared out of all values that were entered. I'd like it to grab all the values at once but that isn't happening.

Also, you'll notice I have some 'var' statements commented out. I was trying to use them so that I can later shortcut my script by concatenating using a shorter variable.

(ie - using the variable 'cluster' instead of 'document.forms.myForm.cluster.value' when I'm writing the rest of the script).

However something isn't right as no matter where I try putting the var statements I get errors that those variables are undefined. I even tried defining them at some point first with some random value but that didn't help either), so that's why I commented them out for now.

anyway, here is my feeble attempt at writing this script, any help or guidance would be much appreciated.

Code:

<!DOCTYPE html PUBLIC "-//WC3//DTD XHTML 1.0 Transitional//EN">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
	<title>Router Subnet Commands</title>
</head>
<body bgcolor="#FFFFFF">	
<script language="Javascript" type="text/javascript">

//var cluster = document.forms.myForm.cluster.value;
//var subnetip = document.forms.myForm.subnetip.value;
//var routerip = document.forms.myForm.routerip.value;
//var cidr = document.forms.myForm.cidr.value;

function merge() {
console.log(document.forms.myForm.cluster.value) + console.log(document.forms.myForm.subnet.value) + console.log(document.forms.myForm.router.value) + console.log(document.forms.myForm.cidr.value);
}

</script>

<form id="myForm">
<input name="cluster" id="cluster"/> cluster number <p>
<input name="subnetip" id="subnetip"/> subnet IP address <p>
<input name="routerip" id="routerip"/> router IP address<p>
<input name="cidr" id="cidr"/> CIDR <p> 
<input type="submit" value="Get Commands" onclick="merge()" />
</form>

</body>
</html>

Any advice would be much appreciated.

Gmail Mail Merge: Editing Script

I'm trying to setup a mail merge using a gmail docs script from http://www.labnol.org/software/mail-...h-gmail/13289/. So far, it works pretty well, but I want to edit it to include the following:

1) The script should start with "Dear Noah" as opposed to "Dear Noah_Kaplan"

2) I want to add my canned response to the script so that it always appears at the bottom of the e-mail.

3) Lastly, I want the outgoing mail to be saved as individual drafts in my drafts folder in gmail before it's sent out. That way, I can decide if I want to add a sentence or two to personalize each individual email draft.

Thanks in advance for your awesome help.

Hi. I am fairly new to JavaScript.
I am having some troubles with arrays.
I am using Chrome 12 beta.

Here is a brief version of the code I am having trouble with
Code:

var array=new Array()
array[0]=new Array()
array[0][1]=new Array()

var array[0][1]=[
  3, 1, 4, 1, 5, 9, 2, 6, 5, ...
];

I do not want to use "array[0][1][n]" because my array has too many items to do that and it is just plain annoying to change the numbers that way.

I get an error on the "var buffers[0][1]=[" line saying:
"Uncaught SyntaxError: Unexpected token ["

What is the problem in my code?

Thank you ahead of time.

Double commars inplace of singles, singles inplace of doubles, single brackets, whole chunks of text that are wrong. In one place in the book it tells me to copy the text in blod and there is none.

I have a choice when creating a new API that I would like other peoples opinions on. Do I use a single Array or Multiple arrays such as:

Code:

array[1][1] = "ID[56]NAME[Hello World]START[10]";

OR

Code:

ID[1][1] = 56;
Name[1][1] = "Hello World";
Start[1][1] = 20;

The API is used for animations so is very heavy work, but would using around 15 multidimensional arrays be too much and a single one be preferable???

I am working on making 2 for loops of 2 arrays to get the total of them. Then I need to get the average heights. This is for a test, yet I have not got a clue, so I need clues as I cant get it to work and I am a new coder to javascript.

Code:

var heights = [15,16,17,18,19];
var numbers = [2,1,6,4,2];
var average = new Array(5);

average = 0

for (var heights = 0; heights <= 5; heights = heights+ 1)
{
total = 0
}
for (var numbers = 0; numbers <= 5; numbers = numbers + 1)
{
total = 0
average = heights / numbers;
}

document.write('The average height is ' + average);

Am I on the right road? I need to use this format and not functions. I have got 2 for statements but maybe I could do this with one, it is so tricky this javascript.

Manipulating Arrays.... Help !!

OK first of all I will post some screenshots of the 'website' I have created so far and explain what is working and what is not working. Then I will post my code and ask for help.

Below is the main screen before any action happens. The three boxes are DIV elements. The writing and dropdown menu in the first box is generated by Javascript code.

Whenever a user selects an option from the dropdown menu. Information about the movie and a picture of the cover are displayed. The movie title, picture filename and movie description are all stored in three separate arrays.

Now for the problem. I have created a fourth array "customerList" and left it empty. Whenever a customer clicks the reserve button it calls a function "myReserve()". This function takes the selection from the dropdown menu, then uses the push function to add the selection to the blank array. I then use the code "arrayLength = customerList.length" to get the length of the customer list. A for loop is used to cycle through the array and display the contents of the array. The problem is it only displays one selection. When reserve is clicked again the newest selection is displayed. Why will it not push the next item into the array?

Javascript code, just skip through the 3 arrays at the top... the problem function is at the bottom.
Code:

var movieTitles = new Array(8)
movieTitles[0] = "The Prestige [2006]"
movieTitles[1] = "The Lives of Others [2007]"

  var m =  movieTitles[i]
  m = m + "<p><br><img src='"+movieCovers[i]+"'></p>"
  m = m + movieDescriptions[i]

Question About Arrays

Do arrays retain its data outside of a function. The reason why i asked this is because i created a global array and then a function. In the function i assaigned values to the global array but when i try to access the global array it gives me a "undefined" or "null" error.

Code:

var myArray = new Array();
var count = 0; 
    
function populate(){
     for(i=0; i < 5; i++){
         myArray[i] = count++;
}

}

Im working on a program where the user enters a line of numbers and then can either sort them in order or can display the minimum number.

Both those seem to work, but for some reason I keep getting three -1 values in my array. So the minimum value is always -1 and when I sort it comes back -1-1-1[numbers i enter].

I cant seem to figure out why my code is doing that.

Code:

  private int[] buildArray(String line) {
        int[]arr = new int[line.length()];
            arr[0] = 0;
                for (int i = 1; i < line.length(); i++){
                     arr[i] = Character.digit(line.charAt(i),10);
                     
		}
            return arr;
    }
    
    private int findMin(int numbers[]) {
    //PRE numbers.length >= 1
        
        int min = numbers [0];
        
        for (int i = 1; i < numbers.length; i++){
            
            if (numbers [i] < min) {
                min = numbers [i];
            }
        } 
        return min;
    }
    
    private String makeString(int numbers[]) {
    //PRE numbers.length >= 1
    int i = 0;
    String s1 = new String ("");
    while (i < numbers.length){
        s1 = numbers[i] + s1;
        i++;
        
    }
    return s1;

    }
    
    private void sort(int numbers[]) {
        for (int i = 1; i< numbers.length; i++){
            int j = i-1;
            int temp = numbers[i];
            while (j >= 0 && temp > (numbers[j])){
              numbers[j+1] = numbers[j];
              j--;
            }
            numbers[j+1] = temp;
        }
    }

Input: 3,1,2,88

output:
Min Value = -1
Line 1 Sorted = -1-1-101288

Any type of help would be very appreciated, Im very new to this still.
