JavaScript - How To Process Text Box Values/ Call Textbox Values To Java Program

Hi,

Can anyone tell me How to send values from application resources.properties file to a java script function in a jsp


Thanks in Advance,
John Ven

I have a bunch of checkboxes like below that the user can check some or all and click the button and see the values of all the selected checkboxes. How can I do that?

Code:

<script>
function alertValues(){


}
</script>


<input type="checkbox"  class ="normal2" value="131971" name="list[]" >
<input type="checkbox"  class ="normal2" value="131973" name="list[]" >
<input type="checkbox"  class ="normal2" value="131975" name="list[]" >
<input type="checkbox"  class ="normal2" value="131977" name="list[]" >

<input type="button" onClick="alertValues()"

Hi,
What's a good way/ideal data structure to achieve this?

The objective of the code/function is to map user-inputted strings into a pair of specific, hard-coded strings. For example, say the user types "firefox" or "ff", or "fx". The output would be the pair ["browser", "mozilla"], for example.

I'm currently using a multidimensional array, but it feels inefficient and I'm having trouble mapping an arbitrary number of inputs into 2 outputs.

Code:

var strings = [ ["input1", "output1a"],
                ["input2", "output1a"],
                ["input3", "output1a"],
                ["input1", "output1b"],
                ["input2", "output1b"],
                ["input3", "output1b"]
              ];

How should I map the elements ["input1", "input2", "input3"] => ["output1a", "output1b"] ?

Another method I used previously was a massive switch statement. This fulfills my needs, but I'm not sure about the efficiency (though if I remember correctly, switch statements become more efficient as size grows, since it uses a hash table?).

Code:

switch (input) {
    case "ff": case "firefox": case "fx" : case "ffox":
        return ["browser", "mozilla"];
    case "ie": case "internet explorer":
        return ["browser", "microsoft"];
    ...
}

Ok, so I have 4 textboxes with ids payment, payment1, payment2, payment3 and with each box is a submit button, named submt1-4

I need to know how I can add all of the values into one textbox named total. so when submit1 is clicked, it will add payment to the total, then when submit2 is clicked, it will add payment1 to the value, etc. But, each text box could be used more than once, so payment could be used 8 times, and each of the 8 times, it needs to add the proper value to the total.

how would I do something like this?

Hi Peers,

i have a button that helps me creating more than one dynamic text box and dropdownlist...
how it possible to capture the values in those dynamic comtrols ?



i am trying the following but did not work ..when the code is excuted it gives me [object]

// Create Text box 1
var newStartDate = document.createElement('input');
newStartDate.setAttribute("type","date");
newStartDate.size=8;

//capture the value in a temp variable val1
var val1 = document.getElementsByName(newStartDate);
alert(val1);


the alert gives [object]

thanks

I am doing a website project and I am currently designing product page.

I have created the text boxes dynamically(as many boxes as the user wants) and he can drag and drop the text boxes in the page.

I need to create a dynamic line from one text boxes to other text boxes and delete the test boxes which the user does not want. I have created the dynamic graphic line.

I know the values of the text boxes can be saved using php in the backend.

But is there any way the values with the dynamically created boxes(with <div></div> elements, not with the text boxes) with values and graphics line can be saved online and the user when log-in again can retrieve the work that he saved? Can we code this either in javascript/php?

Hi,

I'm currently programming a menu editing script and I'm trying to reorder value of text input on change.

What I'm trying to do is when I change the value of a text box it reorders the others.

EX
Start 1 2 3 4 5
Change 3->1
End 2 3 1 4 5

Here is what I've manage to do, it works only when the number is bigger.

Javascript function
Code:

function changeOrder(current)
{
	var num_name = current.name.split("_",2);
	var id = num_name[0]+"_"+num_name[1]+"_number";
	var maxorder = document.getElementById(id).value;
	var currentmax = current.name.substr((current.name.length-1),1)
	if(currentmax <= maxorder && current.value > 0)
	{
		var start = (currentmax > current.value ? 1 : currentmax);
		for(var i=start;i<maxorder;i++)
		{
			var k = parseInt(i)+1;
			x = document.getElementsByName(num_name[0]+"_"+num_name[1]+"_order_"+k);
			x[0].value = i;
			x[0].name = x[0].name.substr(0,(x[0].name.length-1))+i;
		}
		current.name = current.name.substr(0,(current.name.length-1))+current.value;
	}
}

HTML input
Code:

<input type="text" style="width: 20px;" onchange="changeOrder(this);" value="1" name="other_title_order_1">

Thanks for any advices you may have

So I am working on an excercise that the User puts in a Lastname, Firstname, and a score via textboxes. When the user pushes the add student score it should show up in the text area with this format " Brown, John: 92". When looking at the logic, I understand that each text box will need to be different arrays if im right, and then I will have to concat all three arrays into the format and assign it to a variable. Then assign the variable to the value of the text area. I just cannot seem to put the function together or how you would go about it. I just need help with how to go about putting it together. The first code is my body of HTML I'm working with.


Code:

<body>
<div id="content">
    <h1>Student Scores</h1>
	
	<div id="buddy">
	<b>Last Name: </b><input type="text" id="lastName" />
		
	<b>First Name: </b><input type="text" id="firstName" />
	
	<b>Sco  </b><input type="text" id="score" />
	
	<input type="button" id="calculate" value="Add Student Scores" />
	</div>
	
	
	<fieldset>
	<legend>Student Scores</legend>
	<p id="tasks"><textarea id="task_list" rows="20" cols="100"></textarea></p>
	</fieldset>
	
	<div id="yoohoo">
	<b>Average sco  </b><input type="text" id="averageScore" />
	<div>
	
	<div id="yes">
	<p><input type="button" name="add_task" id="add_task"
        value="Clear Scores" /></p>
		
	<p><input type="button" name="add_task" id="add_task"
        value="Sort By Last Name" /></p>	
	</div>
</body>

Hi guys,

Let me explain simply what I do and what I'm trying to achieve:

I got a couple of comboboxes were the user selects a series of numbers. Once a selection is made, the value is appended to an input box. The idea is that the appended values form a telephone number, or at least part of one, that will then be used to search trough a database to look for a matching number.

The code below is what I have done so far:

Code:

<script type="text/javascript">
function displayIndicatif(){
	var sel = document.getElementById("indicatif");
	var text = sel.options[sel.selectedIndex].value;
        var out = document.getElementById("blabla");
	out.value += text+"\n";
		}

function displayBloc(){
	var sel1 = document.getElementById("bloc");
	var text1 = sel1.options[sel1.selectedIndex].value;
	var out1 = document.getElementById("blabla");
	out1.value += text1+"\n";
}
</script>

[...]

<input type="text" id="blabla"/>

[..]

<select id="indicatif" onChange="displayIndicatif();">
	<option value="021">021</option>
        <option value="022">022</option>
	<option value="031">031</option>
</select>

<select id="bloc" onChange="displayBloc();">
	<option value="555" class="021">555</option>
	<option value="666" class="021">666</option>
	<option value="777" class="021">777</option>
</select>

Basically what happens now is this:

combobox indicatif: 021 | 022 | 031
combobox bloc: 555 | 666 | 777

If I select "021" from indicatif, the script will append 021 to the input "blabla". The problem is, if I now select "022", the input will show "021022" instead of replacing the 021 with 022.

What I would like is that, for each combobox, the script replaces the selected value with the new one instead of simply appending it, like instead of say 021022555666 it would show 021555 or 022666 or 021666 depending on what is selected...you get the idea?

Is this doable? Needless to say I'm a total noob at javascript...I adapted the code I got now from some other guy who was trying to achieve almost the same thing and adapted it to my needs, or least, tried to, but now I'm stuck.

Any help is appreciated!

Thanks

Im writing this code for a gas station program. I have been writing and improving my code for about 3 weeks now and its quite long. I have about classes , customer class, office class and a gas pumps classes. I need help on how to get started on finding the total output at the end of the day. Conceptually i know what i have to do but I don't know where to begin writing the code. I think each time there is a new customer i should add the amount of fuel purchased to a new total fuel purchases variable in the gas pump class. If any one could give me some advice or tips on my theory it would be great ! Should I create a method or can i be done without one.
Code:

import java.util.Random;
import java.util.Scanner;
public class Customer
{
	private String carTag;
	private double gasPurchased;
	private int gasType;
	
	public Customer ()
	{
		Random gen = new Random ( );
		carTag = "";
		for (int i = 1; i <= 6; i++)
		{
			
			//a random number between 48 and 90
			int code = gen.nextInt (43)+ 48;
			if ((code <= 64) && (code >= 58))
			{
				i--;
				continue;
			}
			
			carTag += ((char)(code));
			
		}
		
		System.out.println ("a car arrives; tag number:" + carTag);
		
	}
	
	public int getGasType ()
	{
		Scanner inputDevice = new Scanner (System.in);
		//1:regular, 2:plus, 3:premium
		System.out.println ("enter type of gas to buy " + 
				"(1:regular, 2:plus, 3:premium): ");
		gasType = inputDevice.nextInt ();
		return gasType;
		
	}
	
	public double getGasPurchased ()
	{
		Random gen = new Random ();
		gasPurchased = gen.nextDouble ()* 50;
		return gasPurchased;

this is part of a php searchengine script that i wrote to retrieve data from a database and as you can see the last column that is g contains a link which when clicked takes the user to the second php script which retrieves additional information of that entry, but this is done for only single entries so as you can see i introduced checkboxes so that the user can check any number of checkboxes and retrieve information as per their wish

now to do this i created a <input type=text where i want the value of these checkboxes i.e. $id to be posted in a delimited format so that the user can then click the corresponding button and retrieve the information this is the code

<div id="floatMenu">
<ul class="menu1">
<center><li><form name="senddata" method="POST" action="http://localhost/retrieve.php" style="display:inline;"><input id="fasta" type="text" class="multitext"><input name="Fasta" type="Submit" value="Retrieve Fasta"></form>

this is a css floating menu....so far so good....everything went fine....
after this i had to write a javascript to do this and i've been stuck there searching forums for the last 4 days!

this is the javascript i found from somewhere which came close to doing wht i wanted it to do

window.onload = function () {
var cb = document.getElementById('check');
var fasta = document.getElementById('fasta');
cb.onclick = function () {fasta.value = cb.value + ",";
};};

this script only sends the value of the first checkbox in the table, the others are not found by it, mind you its not the first checkbox selected its the first checkbox that is present in the table

how can i resolve this problem so that even if i have n number of checkboxes in my table, if the user chooses to do so they can retrieve n number of information....please help i've almost lost hope in this!

I have a web page created using plsql web toolkit. I want to set the text box values for street line 2 and zip based on user selection in select drop down which is street line 1. The select drop down list is based on a cursor selecting data from the Oracle database. I'm not sure if I need to use an array in the javascript code or if I can set the values some where in my package. Any advice would be appreciated.

Hi everyone , I have been working with java script for a couple of weeks now and have run into some practice obstacles, ok so I am trying to build a html java program for my website and I wants there to be a web page in which users can dynamically change the styles of page elements (e.g.,background, text) by typing the style name into a dialog box. So basically enter a word and the that word should be set to change the attributes once entered in. Ive tried working with if else statements but have run into many problems. Again I am a beginner and am trying to self teach myself if you all could help me that would be great.

Thanks

Hey guys,

Here's the program.




Quote:
import java.util.Random;
import java.util.Scanner;

public class HighLowGame
{
public static void main(String[] args)
{

Random rand = new Random();


int numberOfTries = 0;
Scanner input = new Scanner(System.in);
char repeat;
char ans;
int guess;
boolean win = false;



do {

System.out.println("Pick a number between 0 and 10: ");
guess = input.nextInt();
numberOfTries++;
int numberToGuess = rand.nextInt(10);

if (guess == numberToGuess) {
win = true;
System.out.println("Congratulations you have won!");


}
else if (guess > numberToGuess) {
System.out.println("Your guess was high try again");

}
else if (guess < numberToGuess) {
System.out.println("Your guess was low try again");
}

System.out.println("The number was " + numberToGuess);
System.out.println("You guessed the number in "+ numberOfTries + " attempt(s)");
System.out.println("New game? 1 for Yes, or any other number to quit ");
ans = input.next().charAt(0);

} while (ans == 1);








}
}





Two questions, why doesn't my program let me keep putting in numbers until I guess the right one?

What is wrong with my loop? Pressing 1 should repeat the program, any other number should close.

Thanks!

Hi im trying to make a program that passes an array to a method. the method then finds the smallest number in the array and passes that number back to the main where its printed out. I am getting an error saying: "error: number cannot be resolved to a variable". I am using drjava. here is my code.

Code:

import java.util.*;

public class homeWorkTwo{
  public static void main(String[] args)
  {
    int[] arrayA;
    arrayA = new int[10];
    arrayA[0]=7;
    arrayA[1]=5;
    arrayA[2]=8;
    arrayA[3]=9;
