JavaScript - Switch/case - Why Do We Need To "break"?
This has always puzzled me:
Code: foo="bar"; switch(foo) { case "bar": { alert("a"); } case 123: { alert("b"); } } "a" is displayed because foo=="bar", but even if execution continues to the next block, surely "b" shouldn't be displayed because foo!=123? Does anyone know what the logic behind this is? Similar TutorialsHi, I am a beginner in programming however I am close to completing this task for my uni course and I know what method is needed "toLowerCase()" yet I am not sure on where it needs to be placed. If i paste in the question and then the coding I have done so far any helped would be greatly appreciated. Thanks in advance to everyone who replies QUESTION: function findAnyU(s) - to discover if string s appears in any of the URLs in the array pages. Gives an alert of s together with 'found' or 'not found' as for find1C. [Note that the search should be case insensitive so that 'lboro' and 'Lboro' and 'LBORO' would all be found in 'www.lboro.ac.uk' - all remaining functions should also be case insensitive in this way] Example call: findAnyU("Lboro") Example result: "Lboro" found MY CODING... var pages = [ "[www.lboro.ac.uk] Loughborough University offers degree programmes and world class research.", "[www.XXXX.ac.uk] Loughborough University offers degree programmes and world class research.

I am completely new to these forums and to programming in general (however, I used to program some games, albeit not very good ones, on a version of BASIC that came with my Playstation 2 about 10 years ago hehe). I have a basic understanding of functions, loops, if/else/switch and an extremely basic understanding of objects/methods. I wanted to consolidate my knowledge by putting it to practical use so I have made a little text adventure game. At the moment it is horrendously non-user-friendly as it has just been me experimenting with functions, if/else statements etc. Anyway, below is my code and I have two specific questions regarding it (but general answers telling me how I could do things more efficiently OR telling me what I should consider studying would be very appreciate also :)). Firstly, I have a little inventory object up top and when the player picks up something in the game I change the inv item to "true" so they can use it later (it seemed logical!). I would really love to know how the user could type in "inv" and for their inventory to be shown back to them. i.e. How could I show only the "true" items of an object? I have tried coding this myself but I really am stumped for an answer. Secondly, you can see in the "north21" function within the "north2" function that I used a series of if/else statements instead of a switch. I would have much prefered to use a switch and then for the case of "go north" have an if/else statement to check if vineclear is true or not (so that they can pass through to the non-existent north3 room). Is this possible? You can use if/else statements within an if/else statement but it seemed when I tried doing that in a switch it didn't like it. I am running this script through an interpreter to play the "game". I understand that JS probably isn't the best for what I am trying to do, it was more just a "see what I can do" exercise more than anything. Thanks in advance for your help and please be nice to me, forums scare me generally :D testgame.txt I have to attach the code in a txt file as for some reason it wasn't displaying properly when I copied and pasted it here.

Join Date Feb 2009 Posts 28,310 Thanks 82 Thanked 4,754 Times in 4,716 Posts Briefly: Code: // based on this: var inv = { sword: false, shield: false, vines: false }; // try this: function displayInventory( ) { var list = [ ]; for ( var item in inv ) { if ( inv[item] == true ) { list.push( item ); } } if ( list.length == 0 ) { return "You have no items in your inventory"; } return "You have these items in your inventory:<ul><li>" + list.join("</li><li>") + "</ul>"; } My code is designed for display in an HTML page, not for use in clumsy console.log( ) coding. prompt() and alert() and confirm() and document.write() and console.log() should be used ONLY when debugging, not for any real work. But if you must use console.log, then try this, to replace the code in italics: Code: return "You have these items in your inventory: " + list.join(","); I know that, when in a loop, you can use the following to exit the loop: Code: break; Is there an equivalent for functions? It would be convenient for error messages, and stopping the rest of the code from executing when there is an error. I just have if statements for each error, and the rest of the code is contained in the else statement. For example: Code: if(document.fn.input.value < 0){ alert("The input cannot be smaller than 0") }else{ //rest of code } It would be better to do this: Code: if(document.fn.input.value < 0){ alert("The input cannot be smaller than 0") break; } //rest of code Is there any way to end a function like this? I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hi all, I'm having a bit of a problem..

The form posts via a .cgi script. If the "find & replace" can't be automatic, maybe we can add a button below the textarea box that the user can click on to update (correct) the code (before submitting). I am not a programmer... so any specifics you can give me will be much appreciated. Thank you. Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ...

At the moment all I managed to find out is that it will run the Program specified by the ProgID: Quote: This code starts the application creating the object (in this case, a Microsoft Excel worksheet). Once an object is created, you refer to it in code using the object variable you defined. http://msdn.microsoft.com/en-us/library/6958xykx.aspx Does it load the program like normal or does it load it within IE's memory? For example if the program crashes then why does IE crash. I would ask more questions but really I am sure there is more to it than simply loading the program. Thanks for any help in helping me get a better understanding. I want to make a function that will also play a sound byte when you click on the large image. i need the sound byte to change with the images. Here is the code that i am using. Code: intImage = 2; function swapImage() { switch (intImage) { case 1: IMG1.src = "images/picture1-lg-over.png" IMG2.src = "images/picture2-sm-top.png" IMG3.src = "images/picture3-sm-btm.png" intImage = 2; return(false); case 2: IMG1.src = "images/picture2-lg-over.png" IMG2.src = "images/picture1-sm-top.png" IMG3.src = "images/picture3-sm-btm.png" intImage = 3; return(false); case 3: IMG1.src = "images/picture3-lg-over.png" IMG2.src = "images/picture2-sm-top.png" IMG3.src = "images/picture1-sm-btm.png" intImage = 1; return(false); } } i have tried many things that involved each case to contain a different IMG1.onClick=""; value but it doesnt seem to change when the case changes. I have also tried making another switch/case that would change the value of the onClick event.. nothing. any sugestions? Hi There, I need your help, I can't seem to get this work, which it theorecticly should work any ideas? <script> var x = 3 switch(x){ case x > 0: alert("overdue") break case x = 0: alert("due today") break case x < 0: alert("will be due") break } </script> Much thanks for everyones help. Cheers, Jay So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items. This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail. Any help would be fantastic. The Code (class references are irrelevant to this example, they belong to the final project): Code: <html> <head> <script type="text/javascript" language="JavaScript"> /* Count up from any date script- By JavaScript Kit (www.javascriptkit.com) Over 200+ free scripts here! */ function getToday(yr,m,d){ var today=new Date() var todayy=today.getYear() if (todayy < 1000) todayy+=1900 var todaym=today.getMonth() var todayd=today.getDate() var simpledate=todaym+""+todayd+""+todayy var firstItem=document.getElementById("listOne"); var secondItem=document.getElementById("listTwo"); var thirdItem=document.getElementById("listThree"); switch(simpledate){ case "10192010": firstItem.style.visibility="visible"; secondItem.style.visibility="hidden"; thirdItem.style.visibility="hidden"; break; case "10202010": document.getElementById("listOne").style.visibility="visible"; document.getElementById("listTwo").style.visibility="visible"; document.getElementById("listThree").style.visibility="hidden"; break; case '10212010': document.write("This code works...why can't I change an elements style within this case block also?") break; default: document.write("Something is wrong") } } //enter the count up date using the format year/month/day getToday(2010,07,26) </script> </head> <body> <div id="theList"> <ul class="rounded"> <li id="listOne" style="display:block;" class="arrow"><a href="#kliwComic-MvPDualBoot"><font size="1px">11/17/10 - </font>MvP: Dual Boot</a></li> <li id="listTwo" style="display:block;" class="arrow"><a href="#kliwComic-MvPTouchScreen"><font size="1px">11/18/10 - </font>MvP: Touch Screen</a></li> <li id="listThree" style="display:block;" class="arrow"><a href="#kliwComic-MvPVista"><font size="1px">11/19/10 - </font>MvP: Vista</a></li> </ul> </div> </body> </html> I'm a bit of a hack at this. Any input is greatly appreciated. Thanks again. |
