JavaScript - Question Please
Hi all
I am doing an assigment and have gotten to the end and cannot get the unordered list to work. If I try having my </script> tag below the </ul> it does not display anything If i have it above it will only display the varible names or what ever I type between the <li> </li> tag and not the varible assigment. num1,2,3,4 being the varible name. ie. </script> <ul> <li>num1</li> I have tryed <li>+num2+</li> also tryed <li>(num3)</li> also tryed <li>'num4'</li> also tryed and does not display </ul> </head> </html> The following does not display any thing <ul> <li>num1</li> I have tryed <li>+num2+</li> also tryed <li>(num3)</li> also tryed <li>'num4'</li> also tryed </ul> </script> </head> </html> I need to get the <li></li> to display not what I type in there but the assigment of the varible name I put in there.,or the output the varible calculation produces. Hope that was easy to understand lol Any advise would be awesome, cheers Shayne Darcy. Similar TutorialsOk i have been working on this for a while now.

I am really not understanding and in my book it only give me a page to read about the animation. I am still new to it. Thanks for looking hello all ive been asked to create a javascript slideshow.... and i don't really understand it that much i know a little javscript but not much........ is thier any helpful sites that i can use to teach you step by step to make a javascript slide show???? also if don't want loads of code to be used, i want the code to be clean insted of loads and loads of code what is just unessary. i will be linking the javascript file to the html file so i need to keep the code to a min LOL CHEERS You are given a mathematical expression containing integers and the basic operations: *,+,-, /. Find the number of unique results that can be obtained by parenthesizing the expression differently. i.e., by changing the order of evaluation of the operations. Note that all operations are integer operations. For example, if the input is 2 ∗ 3 + 6/2, your output should be 4. Plzz help me with this qs......... Could someone please take a look at my code? It's a simple quiz with one multiple choice question and one fill in the blank. When the user clicks on 'submit' I tried to show some kind of response with correct/incorrect images next to the question. It works with the multiple choice question, but not with the fill in the blank. How can I get the fill in the blank question to work. It always shows the answer as being wrong. Thank you.

At first, it looks correct, but if you hover back over the menu, it changes back to the inactive state. Any help would be great! Thanks. Hello, i haven't understood how to find the id from buttons, links, button images to auto click yet for example, i want to CLICK HERE how can i do that? how i find the id (I Own firefox with firebug and know basic html) it will be something like javascript:document.GetElementById('id').click(); right? but just want to know how to find or create ids on sites for auto click thanks I'm not sure if this is the correct forum or not, but here goes. I want to make a very simple XUL document. Just a simple basic window to be opened up, but, i want the XUL to Load and Render an HTML File. I'm not sure about what function(s) to call to achieve this, can anyone give me any ideas to go on? here's what i have so far use my JavaScript Function called LoadFromDisk(FileName), if the file is there or the load is sucessfull, it can be stored as a variable. And then i have a single Division in the XUL document called RenderWindow. From there i set the innerHTML of the RenderWindow to the data that was loaded from the disk. Is this the right way? thanks Thinking in Objects 4 objects w/constructors/overloads min 3 properties on each min 3 methods total was just wondering if anyone had any good links or tutorials to get me started on my first javascript assignment Hi Everybody, I'd be grateful if you could help me out. I need to change the CSS by changing the id when a link is clicked. The id is in the body tag and by default it is named 'first'. i.e <body id="first">. If I click on the link named 'Change id to Second', this should change to <body id="Second">. If I further click on the link named "Change id to Second" this should change to <body id="Third">. My code below works (I have stripped this down to make sense), but only when I click one of the links for the first time. If I am to click the second/ third link, nothing happens: Code: <html>
<head>
<script type="text/javascript">
function changeFirst() {
document.getElementById('blanky').id = 'first';
document.getElementById('second').id = 'first';
document.getElementById('third').id = 'first';
}
function changeSecond() {
document.getElementById('blanky').id = 'second';
document.getElementById('first').id = 'second';
document.getElementById('third').id = 'second';
}
function changeThird() {
document.getElementById('blanky').id = 'third';
document.getElementById('first').id = 'third';
document.getElementById('second').id = 'third';
}
</script>
</head>
<body id=first><!-- I need to change this id -->
<p>Hello, the id above should change when the following links are clicked</p>
<a onclick="changeFirst()">Change id to First</a>
<a onclick="changeSecond()">Change id to Second</a>
<a onclick="changeThird()">Change id to Third</a>
</body>

Any help will be greatly appreciated. Cheers hi, if i have an array of "hop", "skip", "jump" "run", how do i prompt the user to enter a number between 1 and 4 to bring back one of the array list without using an if or switch statement... the code i have so far is: numbers= new Array(); numbers[0]="hop"; numbers[1]="skip"; numbers[2]="jump"; numbers[3]="run"; thanks Hi all together! I have downloaded a javascript obfuscator and checked it out. It seems as it takes my code an put it together with a new function "function(x)" in the eval()-statement. But what does this "function(x)"? I do not understand it... And why is all putted in the eval()-Statement? Can someone help me? -- START-- eval( ( function(x){ var d=""; var p=0; while(p<x.length) { if(x.charAt(p)!="`") { d+=x.charAt(p++); } else { var l=x.charCodeAt(p+3)-28; if(l>4) { d+=d.substr(d.length-x.charCodeAt(p+1)*96-x.charCodeAt(p+2)+3104-l,l); } else { d+="`"; p+=4 } } } return d } ) (" ...MY OLD JAVA SCRIPT... ") ) -- END-- Hi! Im new to the world of javascript, so bare with me. It might be a stupid question but i got a input form, i know how to get the data in but i need to single out one of the numbers. the input looks like: xxxxxx-xxxx I've tried almost everything that i can think of... A nudge in the right direction would be appreciated. I'm in a computer coding class, and I'm having a bit of trouble with Javascript. I'm not looking for anyone to do my homework for me, but any hints you could give me as to why this code isn't working would be greatly appreciated. Basically, I need an empty text box where the user enters their guess as to my age. The user enters their guess, and then gets an answer as to whether their guess is right, too high, or too low. The page looks right, but I can't get the function to work. Thank you... <html> <head> <script> function howoldami(age) if(age=23) { alert("You guessed right!"); } else if { (age>23) alert("I'm not that old."); } else { alert("I'm not that young."); } </script> </head> <body> <form> Guess My Age!<input name="age"><br> <input type=button value=Guess! onclick="howoldami(age.value)"> </form> </body> </html> ok im new to coding and was woundering is there a way to open up a game through a program that could have an attached macro or anything.. like for example i would have a racing game that u need to shift and i open it with the coded program and it shifts like an automatic. i sorry if its in the wrong section . thanks I'm using the following javascript for my main navigation. Quote: var mastertabvar=new Object() mastertabvar.baseopacity=0 mastertabvar.browserdetect="" function showsubmenu(masterid, id){ if (typeof highlighting!="undefined") clearInterval(highlighting) submenuobject=document.getElementById(id) mastertabvar.browserdetect=submenuobject.filters?

I know how the replace method works, but I can't for the life of me figure out exactly what this replace function is doing... Can someone shed somelight for me? the g I *think* is a flag for global replacement... Code: replace(/\s/g, " "); I know that *something* is being replaced by a non-blank space, but what? After some severe experimentation I got to googling for an answer and stumbled upon these forums. So my big question is, is it possible to use getElementsByName() with a variable as the parameter? And if not what is another way I can get at each element based on a variable list of names. Code: var curObjSet = document.getElementsByName(String(idStack[y])).item(0) I'm trying desperately to make my code organic and not to have to hard code field names but without this working its leaving me with out options. Thank you for any time and help provided. - Eric Hello, I'm looking for an example on adding items from a popup window to my current form. So I have a form where a user will request some data and one of the options is to request certain files. So, I would like to add a button which allows the user to open a separate window to choose some files to associate with the form/request. I would then like to see those items show up in my current form . I hope this makes sense :-) Thanks, tom I am a newbie with a newbie question =) I recently took an exam type thing using my Firefox browser (v3.5.3). I still have my browser window open that I used, and when I press the back button on the browser I get a message "To display this page, Firefox must send information that will repeat any action ..." Is there any way (either disk or memory cache) to reload the pages with out having to resend the data, OR is there any way (hex editor) to view the exam (forms) questions?? Just curious, Thanks HI Guys!! My name is Megan and I am a college student in need of some JavaScript help for my computer science class!! My professor is making us complete some stupid class project for finals and I can't figure it out! He suggested that we may try to find a JavaScript Website to help us if we have trouble figuring out how to write the code. I have looked and looked and can't find out how to fix my code!! We have to write code to make a slot machine .. I have started the code based on what he gave us and have tried my hardest to figure out how to complete it but I do not know how to finish it. I have the images working correctly (kind of.. the second one seems to have problems loading? I dunno what I did to mess that up) and the counter working, but I need to make it add 13 credits when all 3 images are the same. I added code that I thought would work but it's not for some reason that I can't figure out. It should also pop up an alert screen when all 3 are correct and you win. I guess this would have to be including with the if statement and something like alert('You win 12 credits!!!') Lastly I need to add code that prevents the person from playing when the credit line is 0 (so you can't get - credits!) and I have no idea how to do this. Any help would be greatly appreciated!
