JavaScript - Altering A Webpage With Java
OK, I appologise in advance if this post is long, but I need this answer, as I'm at my wits end.
So I have this code Code: function SizeSelect(){
if(document.getElementById("JarSize").value=="Small")
document.getElementById("JarPrice").innerHTML="3.00"
else if(document.getElementById("JarSize").value=="Medium")
document.getElementById("JarPrice").innerHTML="5.00"
else if(document.getElementById("JarSize").value=="Large")
document.getElementById("JarPrice").innerHTML="7.00"
}
Which alters the value of JarPrice, based on which JarSize is selected. Which is the code below here. Code: <select id="JarSize" onchange="SizeSelect();"> <option value="Small" >Small</option> <option value="Medium">Medium</option> <option value="Large">Large</option> </select> <span class="price">$<span id="JarPrice">3.00</span></span></div> Now for the hard part. I need this piece of code Code: <a href="javascript:;" onclick="simpleCart.add('name=Mango and Papaya', 'price=5', 'quantity=1');" class="prod_buy">add to cart</a>
to be flexible, so that what ever value JarPrice becomes, that 'price=5' becomes the same. Now, the first piece of code is in a seperate .js file to the other two parts, which sit inside a regular HTML page. As I said, I'm desperate, as this is the only part of my site that isn't working ATM And if you need more information about any part, please don't hesitate to ask, as I will be able to give as much info as I can. Similar TutorialsHi, the source code on the website below i want to know what do i need to change to get the date to show as dd/mm/yyyy instead of mm/dd/yyyy? http://www.nsftools.com/tips/DatePickerTest.htm thanks for your help Hi all, I have a div element (i.e. <div id="main">) that contains a number of links, each with white background colors and its top and left style properties set to different values. I need to do several things with the anchors when they are clicked: When a white anchor is clicked, its background color is turned yellow and its coordinates (top and left style property values) are added to an array. The coordinates for a single anchor is to be separated by a hyphen; coordinates for multiple anchors are to be separated by a comma (eg. "0-9,0-18") When a yellow anchor is clicked, its background color is turned white and its coordinates are removed from the array. The values in the array are to be the value for a hidden input element, all separated by commas. I'm a Javascript novice and don't know where to begin. Can someone help me with this? Thanks in advance, Dude-Dastic Hi, I'd like to insert a date on a webpage in the following format: Monday, May 10, 2010 However, I want to be able to set the date 6 days before the current date. So, if today's date is Monday, May 10, 2010, I want it to instead display the following: Tuesday, May 4, 2010 Can someone please provide me the javascript and html coding to be able to do this? I'd seriously appreciate it. Thanks much in advance!! Can someone please show me a working example of how to load a WebPage from an existing WebPage using Javascript! I have tried googling the syntax and not having any luck. Thanks, Blake Hi please help me with this website. This website is used to list 6 events and then it should accurately countdown to when that event happens. As it is right now it accurately counts days, but hours, minutes, and seconds are counted down incorrectly. Here is the js file: /* New Perspectives on JavaScript, 2nd Edition Tutorial 2 Review Assignment Author: Andrew Duren Date: 8 May 2011 Function List: showDateTime(time) Returns the date in a text string formatted as: mm/dd/yyyy at hh:mm:ss am changeYear(today, holiday) Changes the year value of the holiday object to point to the next year if it has already occurred in the present year countdown(stop, start) Displays the time between the stop and start date objects in the text format: dd days, hh hrs, mm mins, ss secs */ function showDateTime(time) { date = time.getDate(); month = time.getMonth()+1; year = time.getFullYear(); second = time.getSeconds(); minute = time.getMinutes(); hour = time.getHours(); ampm = (hour < 12) ?

I have been trying to learn java coding from a book and have run into a coding question that I'm confused about. Can someone help? I have a one dimensional array of positive integers. I'm trying to create another array with the same length and scan the original array for finding the maximum integer. I am then needing to copy that maximum integer in first position of the created array and set the maximum integer in the original array to zero. For second round, I need to write code to find the maximum integer in the original array and copy that in second position of created array and set the maximum integer in the original array to zero. I need to repeat this until all numbers in original array is zero. My created array should be sorted in positive integer numbers. I need to write this sort method that accepts a one dimensional array of integers that return the sorted array testing this method using the main method. What is JAVA? From where I can learn. Please guide me the best institution that is teaching JAVA in the world. Any online tutorial or site where I can get online material. I am not familiar with this program nor i have any idea. I am waiting for your response because i want to start it immediately. I'm new to coding, And would like to know if java is capable of: Playing a sound file when a name or word is seen on the screen. Or, In this case on a windows sidebar gadget. Thanks ok, so, I honestly have no clue why it wont work..

I'm trying to create a widget for a website that will show the Recent Comments, but will limit what is shown to 1 comment per unique thread. The idea being that the popular threads don't drown out the unpopular threads in the widget. Alas, I do not know Javascript. I am, however, proficient in XSLT. So I mapped out a little transform to get (essentially) what I want, thus: Input: http://anamardoll.disqus.com/latest.rss XSLT: Code: <?xml version="1.0" encoding="UTF-8"?>

Is there an easy way in Javascript to just invoke an XSLT on a webpage and display the results? I've read online that there is, but can find no examples that work for me. I do appreciate any help provided and thank you in advance! (Also, for background: This will be going into the Blogger HTML/Javascript Widget tool, so... yeah.) I maintain a website for a small local restaurant. I do this with FrontPage so I know very little coding. I have an upload manager so the owner can remotely upload a txt or doc file of daily specials to a folder on the server. I would like to put a java script into one of the web pages that would open and display this file on page load. Is that possible and can someone help with the code, Thanks Hi, I need an option to help my family members who does not have computer knowlege in logging onto a online TV channel website. Can you please let us know how to write a script which will open the web page and automatically login with the user id and password. webpage is http://www.yupptv.com/ Thanks in Advance for the help. Regards, scrptlng I went to the PHP section of this site and posted this same question, but someone told me it's a javascript question. I'm trying to carry a string from one webpage to another. The user inputs some data on page 1, the info gets tested for certain elements, then gets sent to page 2. The problem is the strings aren't transferring and I don't know how to use sessions to transfer them. I need recipeNameEl, ingredientsEl, and descriptionsEl to be stored to a string and then transferred to the page the form's action="" attribute points to. How can I accomplish this? Code: <script>
function checkFields() {
var recipeNameEl = document.getElementById( 'recipeName' );
var ingredientsEl = document.getElementById( 'ingredients' );
var descriptionEl = document.getElementById( 'description' );
var helperMsg1 = 'You have not filled in all required fields.';
var helperMsg2 = 'I thought I said no measurements! (No Numbers)';
return notEmpty( recipeNameEl, ingredientsEl, descriptionEl, helperMsg1, helperMsg2 );
}
</script>
<script type="text/javascript">
function notEmpty( recipeNameEl, ingredientsEl, descriptionEl, helperMsg1, helperMsg2 ){
if(recipeNameEl.value.length == 0){
alert(helperMsg1);
recipeNameEl.focus();
return false;}
if(ingredientsEl.value.length == 0){
alert(helperMsg1);
ingredientsEl.focus();
return false;}
if(descriptionEl.value.length == 0){
alert(helperMsg1);
descriptionEl.focus();
return false;}
var alphaExp = /^[a-zA-Z]+$/;
if(ingredientsEl.value.match(alphaExp)){
return true;
}else{
alert(helperMsg2);
ingredientsEl.focus();
return false;}
return true;
}
</script>
I'm trying getting one of my webpage XHTML 1.0 Strict. There is only one error left, namely: document type does not allow element "br" here at this line: Code: container.innerHTML = result.translation.replace(/mdw/g, '<br />'); Obviously this is part of my javascript coding, but it's where the validation goes wrong. I can't put the javascript in an external file since several javascript variables are getting filled by php. I've tried several options, but I ain't a javascript expert.. so perhaps someone can help me out. |
