  • Splitting up input using regular expressions in Java

    - by Joe24
    I am making a program that lets a user input a chemical for example C9H11N02. When they enter that I want to split it up into pieces so I can have it like C9, H11, N, 02. When I have it like this I want to make changes to it so I can make it C10H12N203 and then put it back together. This is what I have done so far. using the regular expression I have used I can extract the integer value, but how would I go about get C10, H11 etc..? System.out.println("Enter Data"); Scanner k = new Scanner( System.in ); String input = k.nextLine(); String reg = "\\s\\s\\s"; String [] data; data = input.split( reg ); int m = Integer.parseInt( data[0] ); int n = Integer.parseInt( data[1] );

  • Need help with tweaking a Dropdown with three options, user selects one - a hidden div appears with correct fields

    - by Jack
    Hello Again, I posted a question on here and got an answer within minutes I'm hoping the wizards on here can help me again. Okay so I'm using a script I found online to try and add this function to a shopping cart form. Here's the setup. I have a payment method dropdown with Visa, Mastercard and Bank Withdrawal as the options. For the credit cards I have one hidden div with a certain set of fields, and for the bank I have another hidden div. Each of the divs have named ID's - #payCredit and #payBank The css for both have margin: 0px and display: none; Here's a peice of javascript I used successfuly on a shipping address checkbox `function toggleLayer( whichLayer ) { var elem, vis; if( document.getElementById ) // this is the way the standards work elem = document.getElementById( whichLayer ); else if( document.all ) // this is the way old msie versions work elem = document.all[whichLayer]; else if( document.layers ) // this is the way nn4 works elem = document.layers[whichLayer]; vis = elem.style; // if the style.display value is blank we try to figure it out here if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined) vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none'; vis.display = (vis.display==''||vis.display=='block')?'none':'block'; }` I was hoping I could change it slightly to meet my needs. Here's the dropdown <label>Payment Method:</label> <select name="payment" id="payment" class="dropdown3" style="width:8em"> <option selected="selected">Select</option> <option value="Visa" onclick="javascript:toggleLayer('payCredit');">Visa</option> <option value="MasterCard" onclick="javascript:toggleLayer('payCredit');">Mastercard</option> <option value="Direct" onclick="javascript:toggleLayer('payBank');">Direct Withdraw</option> </select></li> The current result is that it kinda works. I can open the dropdown and select Visa and it appears, if I select Visa again it disappears, if I select Visa and then select bank, both appear. You can see what i'm working on here - http://test.sharevetcare.com/bestfriends/cart3.html

  • How to integrate a GWT app into another Web-Framework?

    - by tigger
    I need the ability to load and start a GWT App at any time in an Echo2 environment. My first approach was to load and execute the nocache.js in a Client-Server sync using var script = document.createElement("script"); script.setAttribute("src",javascriptURI); script.setAttribute("type","text/javascript"); document.getElementsByTagName('body')[0].appendChild(script); This call basically works, but when the script is executed it operates on an EMPTY document instead of the current document of the Echo2 application. Has the script to be somehow initialized first or is there any event required? The GWT application/script works fine if it's included in the start-up HTML of the application, so I assume the GWT App to be correct. The original standalone HTML of the GWT App has the HTML script tag in the body as well.

  • Fractional Calculator in Java

    - by user2888881
    I am trying to create a fractional calculator in Java with inputs of mixed fractions, proper fractions, improper fractions or integers. It should include the four basic operators as well. The program should be set up as a loop where it is continuous until the user types "quit". I have coded the beginning loop but have no idea where to go from there. Please help, I am a beginner and would really appreciate it. Thank you again. This is what I have so far: import java.util.*; public class FractionCalculator { private static Scanner input; public static void main(String[] args) { input = new Scanner(System.in); String x = "quit"; System.out.println("Enter a fraction"); while (true) { String y = input.next(); if (y.equals(x)) { break; } } } }

  • Form validation in JAvascript with Regexp

    - by Nikita Barsukov
    I have a webpage with an input field where only digits are allowed. The input field has an onkeyup event that starts this validating function: function validate() { var uah_amount = document.getElementById("UAH").value; var allowed = /^\d+$/; document.getElementById("error").innerHTML = document.getElementById("UAH").value; if (!allowed.test(uah_amount)) { document.getElementById("error").style.backgroundColor = "red"; } } Everything works as I expect until I hit Backspace button to remove some characters. In this case function always behaves as if I entered letters. How to correct this?

  • How to refer to the true 'body' of a page? [NOT iFrame body]

    - by Jim
    I have a script that create a new div element. Then, I want to append the div to the body of the page using appendChild method. The script is look like this : var div = document.createElement('div'); div.id = 'newdiv'; document.body.appendChild(div); Unfortunately, the div also appended to the body of iframes. So, my question is, how to refer to the true body of the document, not including the body of the iframes? That way, the div just appended once, to the "true body" of the document. Thanks before, and sorry if my english is bad. :-D

  • Why use a "do while" loop?

    - by Stanni
    Hi, I've never understood why using a do while loops is necessary. I understand what they do, Which is to execute the code that the while loop contains without checking if the condition is true first. But isn't the below code: do{ document.write("ok"); } while(x == "10"){ document.write("ok"); } The exact same as: document.write("ok"); while(x == "10"){ document.write("ok"); } Maybe I'm being very stupid and missing something obvious out but I don't see the benefit of using do while over my above example.

  • Targeting an iFrame once with jQuery

    - by user275074
    Hi, I have a series of frames (4) which are used in a page to create loading of dynamic content through Ajax calls. In each of these frames I target parent level elements and update them with there respective content e.g. $("#loadingGrid1",top.document).show(); $("#frameSkills",top.document).hide(); In jQuery is there a way to instead of targeting specific elements on the parent page multiple times, simply target the page once into a variable e.g. var parentPage=$('#frameSkills',top.document); And then use this variable to apply content like $(parentPage #loadingGrid1).hide() Hope I've explained what I'm after enough. Basically, I'm having to call "top.document" in every jQuery selector I make and it seems like a waste of energy.

  • stringindexoutofbounds with currency converter java program

    - by user1795926
    I am have trouble with a summary not showing up. I am supposed to modify a previous Java assignment by by adding an array of objects. Within the loop, instantiate each individual object. Make sure the user cannot keep adding another Foreign conversion beyond your array size. After the user selects quit from the menu, prompt if the user want to display a summary report. If they select ‘Y’ then, using your array of objects, display the following report: Item Conversion Dollars Amount 1 Japanese Yen 100.00 32,000.00 2 Mexican Peso 400.00 56,000.00 3 Canadian Dollar 100.00 156.00 etc. Number of Conversions = 3 There are no errors when I compile..but when I run the program it is fine until I hit 0 to end the conversion and have it ask if i want to see a summary. This error displays: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at Lab8.main(Lab8.java:43) my code: import java.util.Scanner; import java.text.DecimalFormat; public class Lab8 { public static void main(String[] args) { final int Max = 10; String a; char summary; int c = 0; Foreign[] Exchange = new Foreign[Max]; Scanner Keyboard = new Scanner(System.in); Foreign.opening(); do { Exchange[c] = new Foreign(); Exchange[c].getchoice(); Exchange[c].dollars(); Exchange[c].amount(); Exchange[c].vertical(); System.out.println("\n" + Exchange[c]); c++; System.out.println("\n" + "Please select 1 through 4, or 0 to quit" + >"\n"); c= Keyboard.nextInt(); } while (c != 0); System.out.print("\nWould you like a summary of your conversions?

Thank you.

  • Disable form submission via Enter key on only _some fields

    - by justSteve
    I want to retain the conventional 'form submits when i press Enter' behavior because users are familiar with. But by reflex, they often hit enter when they finish with a text input box - but before they are actually done with the complete form. I'd like to hijack the Enter key only when then focus is on a certain class of input. Looking Related Questions this looks like what I'm looking for: if (document.addEventListener) { document.getElementById('strip').addEventListener('keypress',HandleKeyPress,false); } else { document.getElementById('strip').onkeypress = HandleKeyPress; } but the if (document.addEventListener) { is unfamiliar.
