JavaScript - Random Function In Addition To Existing Code
I need help adding an additional function to some existing java script code I already have. In addition to the functions already on this js, I want make it so the banner displays one of the images randomly on each new page load. I have an external js file that this page also links too. Not sure if I need to post that also. I was hoping to just add to this code. Any help is greatly appreciated

The only problem i have is making the background image width and height 100% so that the entire image fills in the screen and fills in on resize of window. Please Help...thanks in advance Hi there, I'm looking for some help with modifying an existing function which controls the highlighted states of a multi level js accordion menu. I have had to use javascript due to certain css elements not working in safari browsers. My problem is due to the multi level aspect as when a sub link is clicked, the parent link above it then deselects. I need the parent link to stay active when its sub links are clicked and only deselects when a link outside of that list is clicked upon. I understand the theory of adding a conditional statement but simply don't know how to apply it correctly within the function...any help would be very much appreciated. Here is the existing function which tells a link to be active or selected: Code: var Lst;
function CngClass(obj){
if (Lst) Lst.className='.topnav';
obj.className='selected';
Lst=obj;
}
and here is the menu code: Code: <ul class="topnav"> <li><a href="#">Home</a></li> <li><a onclick="CngClass(this);" href="#">Top Link 2</a> <ul> <li><a onclick="CngClass(this);" href="#">Cookies</a></li> <li><a onclick="CngClass(this);" href="#">Events</a></li> <li><a onclick="CngClass(this);" href="#">Forms</a></li> <li><a onclick="CngClass(this);" href="#">Games</a></li> <li><a onclick="CngClass(this);" href="#">Images</a></li> <li><a onclick="CngClass(this);" href="#">Navigations</a> <ul> <li><a onclick="CngClass(this);" href="#">CSS</a></li> <li><a onclick="CngClass(this);" href="#">JavaScript</a></li> <li><a onclick="CngClass(this);" href="#">JQuery</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tabs</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tutorials</a> <ul> <li><a onclick="CngClass(this);" href="#">HTML</a></li> <li><a onclick="CngClass(this);" href="#">CSS</a></li> <li><a onclick="CngClass(this);" href="#">JavaScript</a></li> <li><a onclick="CngClass(this);" href="#">Java</a> <ul> <li><a onclick="CngClass(this);" href="#">JSP</a></li> <li><a onclick="CngClass(this);" href="#">JSF</a></li> <li><a onclick="CngClass(this);" href="#">JPA</a></li> <li><a onclick="CngClass(this);" href="#">Contact</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Tabs</a></li> </ul> </li> <li><a onclick="CngClass(this);" href="#">Contact</a></li> <li><a onclick="CngClass(this);" href="#">Upload script</a></li> </ul> Thanks for any help or advice.

I have recently used this tutorial: http://net.tutsplus.com/tutorials/ph...-confirmation/ to develop a more complex sign up form for a competition for a client. Basically, the way the validation has been done is different to many other validation methods I've used before and don't understand how to implement it, for some additional requirements. This is an example of the PHP validation code that I have altered, to suit my form requirements: Code: //quick/simple validation
if(empty($code)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your entry code'); }
if(empty($name)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your name'); }
if(empty($email)){ $action['result'] = 'error'; array_push($text,'You forgot to enter your email address'); }
This code only validates that there is content in those fields. But, for example on the 'entry code' field, I would like to put a maximum character input there and restrict certain characters, as well as a standard 'email' validation, so that the form is sent through to the database correctly. If anyone knows how I can do this, with this sign-up form in particular, please assist me, as every other method I've tried to work with this form hasn't worked and caused the form to error. Thank you in advance. ***I need to randomise the order of some questions that are in this format. Any ideas? Thank you!*** <CODE> <!---Question4---> <form name="form4" method="post" action=""> <h3><p>First One</p></h3> <p> <label><input type="radio" name="q4" id="w1" value="1" </label> <label><input type="radio" name="q4" id="w2" value="2" </label> <label><input type="radio" name="q4" id="w3" value="2" </label> </p> </form </CODE> Hey all, I have a sentence generator running on a site. I am using sort to shuffle the array and pop to return the item. All is well, except Safari does not shuffle the array. Here is the technique I am using: Code: <script type = "text/javascript">
var adj=["invisible", "running", "eating", "mad", "talking", "jumping", "living", "weird", "super"];
for (i = 1; i <= 4; i++){
adj.sort(function(){return Math.round(Math.random());});
document.write( [
"Bob is" + " " + adj.pop() + "." + "<br>"
]);
}
</script>
In most browsers it generates 4 unique sentences. But in Safari it does not shuffle the array so it will always output: Bob is super. Bob is weird. Bob is living. Bob is jumping. Any ideas as to what is happening? I've a list of questions and i want them to appear in random order but I'm unable to do so at the moment. Is there a way of randomizing them by ID name or similar seem as each Question has Three answers via radio buttons and I've them grouped together by ID name?
Hi there! I'm trying to retrieve the integer value in the string: #10 So I'm using the JS Split function Code: <script type="text/javascript">
var str="#10";
document.write(str.split("#"));
</script>
Is the code I'm using, but I keep getting a comma before my result.. in this case, my result is ",10" What should I do? Thanks! Kind Regards Matthew P.S. I know that it's an array, but is there still anyway for me to get rid of the comma? Another homework assignment that I can't quite seem to get to work... I've been asked to do the following using javascript: -Create a function named randInt() with one parameter of "size". Declare a variable named "rNum" equal to a random integer between 1 and the value of the size variable. Return the value of the "rNum" varialbe from the function. -Create a function named getQuote() with one parameter anemd "qNum". The function should create an array named mtQuotes with five quotes; there should be no quote for the array index "0". Return the value of the mtQuotes array for the qNum index. - In the div element of "quotes" insert a script with the following commands: Declare a variable named "randValue" which is euqal to a random integer between 1 and 5 (use the randInt() function). Declare a variable named "quoteText" containing the quote whose array index value is equal to randValue. Write the value of quoteText to the web page. Here is what I have...it returns undefined. thanks. Code:
<html>
<head>
<script type="text/javascript">
function randInt(size) {
var rNum=Math.ceil(Math.random()*5);
return(rNum);
}
</script>
<script type="text/javascript">
function getQuote(qNum);
var mtQuotes = new Array();
mtQuotes[0] = "";
mtQuotes[1] = "I smoke in moderation, only one cigar at a time.";
mtQuotes[2] = "Be careful of reading health books, you might die of a misprint.";
mtQuotes[3] = "Man is the only animal that blushes or needs to.";
mtQuotes[4] = "Clothes make the man. Naked people have little or no influence on society.";
mtQuotes[5] = "One of the most striking differences between a cat and a lie is that a cat has only nine lives.";
return mtQuotes[qNum];
</script>

Then these are the directions given in the book. 1. In the head section, just above the closing </head> tag, insert a script element that accesses the code in the random.js file. 2. add a second script element for the cod e that you'll add to the mpl2.htm file 3. Within the second script element, create a function named showImg(). The purpose of this function is to write an inline image tag into the current document. The function has no parameters. Add the following statements to the function: a. Add the following multiline comment to the start of the function, just below the opening showImg() function statement. The showImg() function displays a random image from the 0.jpg through 9.jpg files. The random image is designed to thwart hackers attempting to enter the library records database by requiring visual confirmation. b. Declare a variable named imgNumber equal to the value returned by the randomInteger() function. Use 9 as a value of the size parameter in the randomInteger() function. c. append the statement that creates the imgNumber variable with the following single-line comment: Return a random number from 0 to 9 d. inster a command that writes the text <img src='imgNumber.jpg' alt='' /> to the document, where imgNumber is the value of the imgNumber variable. 4. scroll down to the bottom of the file and locate the last table cell in the document. Within this empty table cell, insert a script element. 5. within the script element, call the showImg() function five times. YOu do not need to specify a parameter value. ___________________________ It's a lot of info but I just can't figure out how to get the images to show up, any help will be appreciated, I think I gave all the info needed. This little snippet of code produces random quotes but sometimes gives a missing quote between two quote marks. Code: <HTML>

Hello! I am trying to create a javascript code in which I prompt the user for a number (an integer from 0 to 100) to search for, then search a function with the number they entered and then display whether the number was found, and if found, a location where it can be found within the list. Can you please tell me what is wrong? <html> <head> </head> <body> <script language = "javascript"> var list = new Array(200); for (var i=0; i < 200; i++){ list=Math.round(Math.random()*100) + " "; document.write(list); } var value=prompt("What is the number you are searching for? ", " "); if (list[i]==value){ {alert("Number has been found in location" +i)}; } </script> </body> </html> Thank you hat i'm trying to achieve is to add two numbers using do while loop. below is the code however result wont show up. i cant seem to determine the error. help me pls. Quote: <script = "text/javascript"> function myanswer(x,y){ x=parseInt(x); y=parseInt(y); i=1; sum=0; do { sum=x+i; i++; } while(i<y) document.myform.asnwer.value=sum; } </script> <form name='myform'> Enter First number:<input type='text' name='x'></br> Enter Second number:<input type='text' name'y'></br> Result:<input type='text' name='answer'></br> <input type='button' value='Click on Me!' onclick="myanswer(myform.x.value,myform.y.value);"</br> </form> Code: var purchasePrice = window.prompt("Please enter the purchase price:", 0);

I am still getting the same error, concatenation instead of addition, i can't figure out why. (i.e input 50, result 505 instead of 55.) Hi, I'm just learning JS by going through a book, while trying one of the examples in the book I ran into a problem with " + " operator. It think it's best I show by example (don't worry it's a fairly short script): Script Code: /* This is an attempt to do some math with javascript */
var a;
var b;
var c;
a = prompt("Pick your favorite number");
b = prompt("Pick your second favorite number");
c = a + b
document.write("a = " + a + ", b = " + b + ", c = " + c + "<br />");
document.write("<br />a + b = " + c + "<br />");
c += 6
document.write("<br />c + 6 = " + c + "<br />");
c -= 5
document.write("<br />c - 5 = " + c + "<br />");
c *= 3
document.write("<br />c * 3 =" + c + "<br />");
c /= 2
document.write("<br />c / 2 = " + c + "<br />");
c %= 7
document.write("<br />c % 7 = " + c + "<br />");
if (c > 0) {
document.write("<br /> Wrong!");
}
else {
document.write("<br /> You, I like")
}
Output Quote: a = 3, b = 4, c = 34 a + b = 34 c + 6 = 346 c - 5 = 341 c * 3 =1023 c / 2 = 511.5 c % 7 = 0.5 Wrong! As you can see the script doesn't execute the mathematical operation for addition. It instead strings it together. What am I doing wrong? Dear Experts I have following codes, it works fine to sum. but when I enter these values 2100.49+100.20 then it says 2,200.6,899,999,999,996 insted of 2,200.69. How to overcome this problem.

So what I know about JS, you could write on a postage stamp, but I want t6o know if this is possible: On Page A: The user fills out a form, stating how many of each time of item they want, and the clicks submit, which mails the form to me (GenericPHP Mailer), and is rederected to page B. (That I can do) On Page B: The value of the items in the form on Page A is calculated, then a link is generated with a random order number, and the value of the order as link parameters. Can I do this? and how? |
