JavaScript - Best Program For Compressing Javascript?
What is the best program or website for compressing Javascript? Optimally, I would like it to optimize variable and function names. I also have a tiny bit of PHP in the code, so it would be nice if it could recognize that but not a big deal if it can't.
Thanks in advance for the suggestions! Similar TutorialsI receive an input stream which is compressed by ZLIB. I need to de-compress the same on the client side using JavaScript/Ajax/JQuery, etc. Please help For class NumericQuestion Add setAnswer, a method that takes a double as input, converts it to a string and calls setAnswer in the superclass Question to store the answer. o Add checkAnswer, a method that takes an answer in string form, converts it to a double, gets the correct answer in string form from Question, converts it to a double, and returns true if they are within 0.01 of each other and false otherwise. For class quiz Change main so that all three questions are asked. presentQuestion that prints out the correct answer, only when the answer is wrong public class NumericQuestion { private String text; private Double answer; /** * Constructs a question with empty question and answer. */ public NumericQuestion() { text = ""; answer = 3.1416; } /** * Sets the question text. * @param questionText the text of this question */ public void setText(String questionText) { text = questionText; } /** * Sets the answer for this question. * @param correctResponse the answer */ public void setAnswer(Double correctResponse) { answer = correctResponse; } /** * Checks a given response for correctness. * @param response the response to check * @return true if the response was correct, false otherwise */ public boolean checkAnswer(String response) { return response.equals(answer); } /** * Displays this question. */ public void display() { System.out.println(text); } } import java.util.Scanner; public class Quiz { public static void main(String[] args) { Question first = new Question(); first.setText("What inherits data and behavior from a superclass?"); first.setAnswer("subclass"); ChoiceQuestion second = new ChoiceQuestion(); second.setText("Which modifies the object on which it operates in some way?"); second.addChoice("Accessor", false); second.addChoice("Mutator", true); second.addChoice("Method", false); second.addChoice("Variable", false); NumericQuestion third = new NumericQuestion(); third.setText("What is the numeric value for PI?"); third.setAnswer(3.1416); presentQuestion(first); presentQuestion(second); //presentQuestion(third); } /** Presents a question to the user and checks the response. @param q the question */ public static void presentQuestion(Question q) { q.display(); System.out.print("Your answer: "); Scanner in = new Scanner(System.in); String response = in.nextLine(); System.out.println(q.checkAnswer(response)); } } I'm very new at Javascript and writing programs so I'm not sure if this is even possible to do. I want to write a program that allows someone to select four tasks from a dropdown menu. The tasks are each 1 hour long. I want the program to calculate the number of hours and display that information below the tasks. I also want the person to be able to add or remove tasks. I get how to save tasks and display the results but I don't know how to calcuate the number of hours. Any suggestions? Here is what I have so far: Code: <!doctype html>

Hello people CF, I need some help with this Javascipt program that im trying to make. Ill provide you with the algorithm i have made and the javascript code. I only know basic javascripting and i had a lot of help with this. I need help getting the javascript code for comparing last date modified, renaming the copied file with last date modified, also i can get it to copy 1 file, but i need it to loop through all the files in the given folder. Algorithm Code: // get source and destination folder path // check if folder exists // if source folder exists, continue with the process, otherwise display an error message // if destination folder exists, proceed with transferring the files // get the file collections in the source folder // loop through each file to check if the file has been modified // if the file exists, check file attributes to the source file; 32 means file has changed // if file has changed, // compare the last date modified of the source and destination file // if the source last date modified is greater than the destination last date modified then // rename the destination file by appending the last date modified // to its file name and then transfer the lastest file from the source folder // otherwise, no need to copy the file and move to the next file // otherwise, do nothing and move on to the next file // otherwise, create a folder first before proceeding with transferring the files I had a lot of help with this Code: <HTML>

Hello I am trying to send some values in combobox2 depending on one value selected in combobox1. Both are in php. Following is the code for combobox1 - Code: <td><div id="Gen_Core">
<?php
$sql="SELECT t.Main_CoNo, t.Main_CoName FROM Main_Course t WHERE t.Modl_No ='2' and t.Main_CoName NOT IN (SELECT t1.Course_Name from Course t1 where t.Modl_No = t1.Module_ID and Student_ID='$Stud_ID')";
$result=mysql_query($sql);
$options="";
while (@$row=mysql_fetch_array($result))
{ $id=$row["Main_CoNo"]; $name=$row["Main_CoName"]; $options.="<OPTION VALUE=\"$id\">".$name.'</option>';
}
?><select size="4" style="width:100px; font-size: 10px;" name="classes[]" id="class_list" onClick="return validateForm()"><?=$options?></select></div></td>
Here is Javascript program - <script type="text/javascript"> function validateForm() { var gen=document.forms["select"]["classes"].value; alert("hi"); } </script> If I select one value from this combobox1, I want to send that value to java script program which is not working...It is not going to Javascript program at all.. I tried couple of things like onClick, onSubmit in form, in select etc. But it seems nothing is working... What I want is - If one option is selected from combobox1, then javascript program should recognize it and send values for combobox2. How will I do it? Really confused..... I am trying to create a javascript program that will assign a number based on a score. If the grade (number) is 90 or above it assigns a 4, if it is in the 80's its assigned a 3, etc. So far: Code: <<?xml version = "1.0" encoding = "utf-8"?>

Where do I go from here? I have no idea whats wrong. I have an homework for a web development class. I wrote a program that would be displayed on a webpage that returns the users zodiac sign.

I am very new to coding. The below is an assignment for a class. It is a "game" which is supposed to do the following: When your program starts up it must display the image that will move around, a Start button, a Stop button, and a way for the user to specify an interval before a new game begins. The default interval must be 1000 msec. When the user presses Start, a new game starts and the selected image is displayed at a random place. The image must move to a new random place once per interval. If the user presses the Stop button, the image must stop moving, and a subsequent Start must start everything over from the beginning. Each time the user successfully hits the image, the program must move the image to a new random place immediately (i.e., not wait for the current interval to end). When the user has hit the image 3 times, the program must display a confirm dialog box that reports the elapsed time and that also says something like "Another game?" If the user pushes OK, that starts a new game immediately (no need to push Start again). If Cancel is pushed, the program stops. I have been working on this for hours, but it does not work properly. Obvious issues: the game starts running when the page loads, instead of when the start button is pushed. The confirm at the end does not cause a new game to start. The time/ elapsed time calculations are not functioning properly/ the elapsed time always displays as 1 sec. Code: <html>

Hi! frnds, I was wondering if you could help me with the JavaScript programing... Every possible help will be appreciated I am very new to the world of programming and JavaScript but I have some Ideas which I would like to execute and I will learn anything and everything in the way to accomplish them... Program: user end: the page is about users priorities and displaying back the selected... the program work as a user reaction based comparison module... where the priorities stored in the program are shown 2 at a time and lets user to select what is more important to him and stores the result in another variable than that variable is shown with another variable which is already stored and the result out of that is stored in another new variable and so on.. in the end it show the result of important selected priorities... 1) say there are 6 variables storing string values: Code: <script type = "text/javascript"> var p1 = "Doctors appointment"; var p2 = "studying for the exam"; var p3 = "Going out for most awaited shopping"; var p4 = "Login on Facebook"; var p5 = "Replying to text msgs"; var p6 = "Go out with friends"; 2) there are two sections on the html document: i) where the variables are displayed dynamically and changes the value on click.. it works like a comparison where user selects (onclick) what is more important to him shows the next value and so on... in the end stores the result... functioning(I have no I idea how to do this): say on the html document only two variables are displayed at first and than the user selects one of it as more important to him so the result is stored in another new variable than that new variable is shown with the third stored variable and once one of them is selected it is stored in another new variable and is compared with forth stored variable and so on till the last selected is stored as the result1... all comparisons must happen on the same div of the html document procedure has to loop three times till 3 results (result1, result2, result3) out of six are selected more important... result1 has to be removed from the next loop for result 2 as result1 is already selected important by the user.. result1 and result2 are to be removed from the next loop for result 3 as they are already selected important by the user ii) the second section displays important 3 results (result1, result2, result3) selected by him... my friend told jQuery can do the dynamic comparison part but I don't know how to use it... the logic of creating new variable for storing result and then comparing can be improved or changed... Please help i am new in programming and learning it from lynda but i am trying to make a program which according to me is good enough but its not working and i am using free javascript editor for compiling and coding <!DOCTYPE html> <html> <body> <script> var a = 5; var b = 10; var c = 30; var d = a + b + c; alert("the value of d is" + d); </body> </html> Please tell me where is it i am making mistake Reply With Quote 01-08-2015, 11:56 PM #2 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts You forgot the </script> ending tag. I am having trouble with JavaScript code and do not know why it is not working. I have the code I think is right but it is not showing up in my browser when run. Any ideas? Also are there any other ways to read in an xml file using javascript? please list if so. Thanks to codingforums that help me to gain success with my javascript program! Please let me know what do you think about it: http://backslash.altervista.org/messa/mass_search.html The js script read the page http://backslash.altervista.org/messa/orari_messa.html and get the church's data and the mass's time. I know it'll better use a db but i have no control on server where the html page is (the mine is only a copy) and i want to do something that if the owner of the server want put in, it can without problem. Any review will be very appreciated Thanks ps: look at the footer pps: sorry it's all in italian I am attempting to create a javascript program for an imaginary airline reservation system. How its supposed to work is you type in 1 or 2 depending on which class you want and the program assigns you a seat. If seats are full, prompts come up for alternate classes.

{

} // end if

No idea why it is not showing up!? Hello all out there I am going to post this in 2 separate views. I am working on an assignment from this link http://books.google.ca/books?id=aG_T2aD ...

I do not know much about the compilers or how these things run. I do however have a good eye for trends and can figure just about anything out by looking at it. With that; I have a game that uses a exe launcher with a built in patcher. I have found the code for the launcher. There are several "jquery" scripts for basic components like scroll wheel. There are also things like "downloader.js", "inputs.js". I am interested in seeing what (and more precisely how many) ip addresses are being retrieved. I fear this patcher is using a hidden bittorrent like download system. The code for "downloader" is pretty basic. It clearly uses some other script, but I am wondering if you can point me in the direction of a utility to monitor running JS so that I can see what is being returned. Code: _Downloader = function()
{
this.downloadStatusCallback = null;
}
_Downloader.prototype =
{
setDownloadStatusCallback: function(callback)
{
this.downloadStatusCallback = callback;
},
addDownload: function(downloadName, metaUrl, outputPath, authorizationURL) // returns bool
{
return document.SSNLauncher.SSNLauncher_ReturnBool('addDownload', 'string:' + downloadName + '|' + 'string:' + metaUrl + '|' + 'string:' + outputPath + '|' + 'string:' + authorizationURL + '|');
},
removeDownload: function(downloadName) // returns bool
{
return document.SSNLauncher.SSNLauncher_ReturnBool('removeDownload', 'string:' + downloadName + '|');
},
getDownloadOption: function(downloadName, optionName) // returns string
{
return document.SSNLauncher.SSNLauncher_ReturnString('getDownloadOption', 'string:' + downloadName + '|' + 'string:' + optionName + '|');
},
setDownloadOptions: function(downloadName, enableBitSources, enableWebSources) // returns bool
{
return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadOptions', 'string:' + downloadName + '|' + 'bool:' + enableBitSources + '|' + 'bool:' + enableWebSources + '|');
},
getDownloadActive: function(downloadName) // returns bool
{
return document.SSNLauncher.SSNLauncher_ReturnBool('getDownloadActive', 'string:' + downloadName + '|');
},
setDownloadActive: function(downloadName, active) // returns bool
{
return document.SSNLauncher.SSNLauncher_ReturnBool('setDownloadActive', 'string:' + downloadName + '|' + 'bool:' + active + '|');
}
}
function __Downloader_reportdownloadStatus(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft)
{
if (SSN.Downloader.downloadStatusCallback != null)
{
SSN.Downloader.downloadStatusCallback(downloadName, state, active, totalBytes, bytesLeft, maxIncoming, averageIncoming, currentIncoming, maxOutgoing, averageOutgoing, currentOutgoing, bytesRead, bytesSent, scanBytesLeft);
}
}
I have tried on several occasions to teach myself programing. I can get the commands and syntax fairly easily, and I am pretty good at 'coming up' with ways to get something done. I just don't have experience in this field (I'm in medical school) so I do not know about the tools and utilities programers use and scouring the internet has been less than fruitful. Anybody capable of pointing me in the direction of finding a utility to monitor running js (if that is even possible =/). I use dreamweaver CS5 to explore js code. Why doesn't this work? Both files are in the same folder. I'm sure I've done this many times before??? HTML File "Test.htm" :- Code: <html> <head> <script type="text/javascript" src="Test.js"></script> </head> <body> <h1>My First Web Page</h1> <p id="demo">This is a paragraph.</p> <button type="button" onclick="displayDate()">Display Date</button> </body> </html> javascript File "Test.js" :- Code: function displayDate(){
document.getElementById("demo").innerHTML=Date();
}
This is my code from prelim to finals. The missing part here is when the input is less than or equal to 65 and greater than 100, the prompt will say INVALID ENTRY. However, after it says Invalid Entry, it must ask you to enter again an Entry until you input a valid entry. It must be terminated after you input from prelim to finals either 0,20,30,40 or after you input a valid entry and after the program calculated it. My program does not terminate after I input valid entries. It just continue to ask grade again and again even it already calculated the grades. I don't know how will I put those code inside the program. I'm getting really confused. Code: <html>
