JavaScript - Newbie To Javascript - Wanting Help
I have been trying to learn javascript for the last few weeks and have come to a brick wall in my thinking. Could you look at this code and tell me where I am going wrong? I would prefer for you to point out what type of an issue I have and the basic syntax of what I am trying to do. This enables me to look at the problem, digest the type of problem and put together an idea of the way to fix the code.
my code (with errors on purpose) Code: <html> <head> <title> <script type=text/javascript src=blah.js></script> </head> <body> (and so on) The response type of response I would like to see is - (from the helper) check to see if you have closed all your lines with the </sectiontype> you need to double check your format on line 4. The correct format would be <script type="type of script" and the src="scriptname.js">. I really appreciate any help you can provide. I just cannot figure a few things out and am getting confused as to how to fix my problems. Code: <!DOCTYPE html>

It is now your turn to pull your own version of <em>The Italian Job</em>. You are able to choose what model of Mini you use and the type of metal bar you want to steal.
Thes rules a
<ul>
<li>You can only load the cargo area of your Mini 1/3 of the way full</li>
<li>The cargo area used cannot weigh more than 1800 lbs.</li>

Similar TutorialsBeen working my *** off on this for a few days trying to keep updating it to make it most efficient with everything I learn... I'm quite proud of it so far considering I'm not actually the best coder lol most JS and PHP confuses the crap outa me unless I do it from scratch. So anyways here is the link. Tell me what you think. Suggestions would be amazing. I'd love to know what I screwed up as long as you explain in detail as to why and how to fix it. I really hate when people hand me a huge snippet and expect me to understand it -_- Thanks Shelby LINK http://opentech.durhamcollege.ca/~in...rittains/labs/ (Its an interface to display my school web design labs... the interface it self has almost NOTHING to do with school work as my labs are mostly based off php and we don't even touch JS till the third year =[ so its safe ^.^ so don't worry I'm not asking you to do my school work ^.^) So I'm picking up on a project that was left off by another developer. He developed the search engine for this website using mustache.js as a templating plugin. However, I have this giant if/else statement in the Javascript to implement it in the template.. but it's ugly in my opinion so I'm curious on if anybody has a better way of going about this. Here is my template in the view: Code: <script id="search_result_item" type="x-tmpl-mustache">
<div id="Box_Book1" class="clearfix search-result-item">
<a href="{{encore_url}}">
<img id="Image1" src="{{ image_url }}" onerror="this.src = 'http://origin.syndetics.com/index.php?upc=x/MC.gif&client=stlip&type=hw7';" class="image {{material_type}}" />

</a>
<div class="title-container">
<span id="textspan5" class="more-details">
<a href="{{ encore_url }}" target="_blank">+ More Details</a>

</div>
</div>
<p id="Text_Author1">

Here is my Javascript that is rending into the template: Code: // this is gnarly i know..hopefully temporary
var item_type = result.material_type;
var label_class;
var label_text;
// This needs rewritten too once search is written in different format
if(item_type == 'z')
{
// EBook
label_class = 'ebook';
label_text = 'EBook';
}
else if(item_type == 'w')

Thank you for any ideas on how to make it prettier.. the item_type is what's terrifying ugly to me. Visitors enter information in textarea's and form fields and I wish to allow them to have this spell checked before submitting. What methods are open to me to do this. Hi everyone, I'm currently stuck with a transition problem in my javascript (actually it's not mine) but since it's a little tricky to explain I've uploaded the page to a friend website so you can take a look at it. http://www.tanzstelle.net/simon/coel...red/index.html So when you hover between the link "car1" and "car2" the fading animation is absolutely correct but as soon as you hover lets say between "car2" and "car3" you'll see how during the transition "car1" shows up for a second - which is imho very annoying. Does anyone know how to tell js not to use "car1" between other transitions? I'm absolutely open to any new ideas but please remember I'm really a javascript/css newbie. Thank you. simon Hi There - I am a bit new to javascript and I am having a tough time coming to a solution to this problem I am having! I will try to explain.. first I have a call to a javascript button in a form of a form button: Code: <input type="submit" value=" Click This Button" onClick="fireMyPopup()"> Now the code for firemypopup() Code:
function fireMyPopup() {
myPopupRelocate();
document.getElementById("mypopup").style.display = "block";
document.body.onscroll = myPopupRelocate;
window.onscroll = myPopupRelocate;
}
Now for the other function referenced there Code:
Code:
function myPopupRelocate() {
var scrolledX, scrolledY;
if( self.pageYOffset ) {
scrolledX = self.pageXOffset;
scrolledY = self.pageYOffset;
} else if( document.documentElement && document.documentElement.scrollTop ) {
scrolledX = document.documentElement.scrollLeft;
scrolledY = document.documentElement.scrollTop;
} else if( document.body ) {
scrolledX = document.body.scrollLeft;
scrolledY = document.body.scrollTop;
}
var centerX, centerY;
if( self.innerHeight ) {
centerX = self.innerWidth;
centerY = self.innerHeight;
} else if( document.documentElement && document.documentElement.clientHeight ) {
centerX = document.documentElement.clientWidth;
centerY = document.documentElement.clientHeight;
} else if( document.body ) {
centerX = document.body.clientWidth;
centerY = document.body.clientHeight;
}
var leftOffset = scrolledX + (centerX - 850) / 2;
var topOffset = scrolledY + (centerY - 200) / 2;
document.getElementById("mypopup").style.top = topOffset + "px";
document.getElementById("mypopup").style.left = leftOffset + "px";
}
As you might have guessed I am using this javascript to show a hidden div and keep it centered and following the screen scroll. This is working fine! It's the next part I am lost on! Here is the code for the div... Code:
<div id="mypopup" name="mypopup" style="position: absolute; width: 800px; height: 400px; display: none; background: #ddd; border: 10px solid #000;">
<form action=(this will call a PL SQL package eventually)>
<input type="hidden" name="CRN" value="'11111'">
<input type="hidden" name="TERM" value="1111">
<input type="hidden" name="CONF" value="y">
<input type="hidden" name="email1" value="1@aol.com">
<input type="hidden" name="email2" value="2@aol.com">
<input type="hidden" name="email3" value="3@aol.com">
<input type="hidden" name="activeemail" value="3">
<input type=''submit'' value='' Yes I Am 100% Sure'' onClick=''document.getElementById("mypopup").style.display="none"''>');
</form>
</div>
Ok now I will get to the nitty gritty here - the first issue is I would like to call the popup function and pass it a variable to signify which email is "active" amongst the hidden email fields. So when I call the popup function I want to say something like: Code: <input type="submit" value=" Click This Button" onClick="fireMyPopup(3)"> In a perfect world this 3 is passed along to fireMypopup and then somehow I would like to somehow change the active email hidden field to 3 as well. So my question is how would I change the code I provided to help me to figure out which email is active in the div. I am open to page refreshes etc, just has to be seemless i suppose. What am I trying to do? To sum it up I am printing an html form with lets say 15 rows. Each row has a column with an "email" button - which is this submit button. This submit button opens the "popup" or shows the div. Depending on which button is clicked I need to determine which email to send the email to. The popup window will be a simple form with 2 text fields and a submit button (which will call a PLSQL script to send the email) - but I need to know which hidden field email is the one that represents the click made. So the email gets sent to the proper email address :-) I am not opposed to new ways to do this - but the one constant is that these hidden fields containing all emails will be there. So if theres 15 emails, there will be 15 hidden fields + 1 for the active indicator (unless theres a better way) Thanks in advance - I am super confused! :-) - Jeff Hello I am totally new to javascript and am overwhelmed with this problem. I have tried a few different things but can't figure it out. I am trying to create a calculation of a total amount based on some fields. Here is what i am trying to do: I have five materials: Flex Vinyl, PSV, Rigid PSV, Vinyl Mesh, and Vinyl Banners Each material has a cost based on a total sq foot. Then two dropdown fields that add a certain amount. Here is what I have so far: Material [DROPDOWN MENU] Width [TEXT FIELD] Height [TEXT FIELD] Grommets [DROPDOWN] UV Coating [DROPDOWN] Total $ [TEXT FIELD AUTO-FILL AMOUNT] Is there a place that I can read about how to figure this out? I believe it would be something like: Width x Height = Total If Material One is selected then below numbers: If Total is greater than 1200 then Cost = .85 If Total is between 200 and 1200 then Cost = .50 If Total is between 20 and 49 then Cost = 1.00 If Less than 20 then Cost = 2.50 If PSV is selected then below numbers: If Total is greater than 1200 then Cost = .90 if Total is between 50 and 1200 then Cost = .75 ....and so on Amount = Cost x Width x Height + Grommets Selected Value + UV Coating Selected Value Any suggested reading/help that I can do to create this form? i am trying to create a simple counter that will start with a fixed number, say 5,000,000 and count up in increments of 1 every ten seconds with no end value set (infinitely).. This is for the non-profit I work for, and it is to show the number of bars of soap we have recycled to distribute to third world countries. Any help is greatly appreciated.
I have been told that what I want to accomplish can be done with javascript. I have never used it, so I am at this forums mercy. I basically have to HTML inputs, the first are simple radio buttons, Yes and No. If no is checked (which is selected by default), then I want the 2nd input to be invisible to the user. Unfortunately I am not the original developer of the code. I have been asked to complete this in a very short amount of time. From the looks of the code, it looks like the condition will have to hide the entire table row with the id of 'voiceintrorow' if radio button 'playintro' with the value of 0 is checked. Here is my code. <tr id="playIntroRow"> <td class="editLabel"><span>*</span>Play Intro:</td> <td>Yes<input type="radio" name="playintro" value="1" /> No<input type="radio" name="playintro" value="0" checked /></td> </tr> //Hide this table row if the above radio button is checked NO <tr id="voiceIntroRow"> <td class="editLabel"><span>*</span>Intro Message:</td> <td><cfscript>voiceIntroRenderer.Render();</cfscript></td> </tr> Iguess javascript can accomplish this, but I don't know. I hope I posted this question correctly. I am very new to JavaScript and am trying to create a page that calculate net annual pay and pops up an alert box that states what they will take home as well as pay in taxes. I have figured my way out of created the boxes to enter fields and even got a calculate button. I cannot figure out the code the actually calculate the taxes! Field one is for first name and referenced by id: num1 Field two is for last name and referenced by id: num2 Field three is enter gross salary with id: num3 I am using 20% for federal taxes and 10% for state taxes and need it to show up in an alert box... Any ideas? Thanks! Hello, everyone i have a mini problem on my hands. I wrote a javascript file, which was linked to a html file. The issue here is that i cannot seem to load my table of contents. i have checked my syntax countless times and my compiler shows no error message. i hope anyone of you out there could help me out. thanks! here are the codes: unsconttxt.htm - <?xml version="1.0" encoding="UTF-8" ?> toctxt.js - /* Author: Date: Filename: toctxt.js function addEvent(object, evName, fnName, cap) { if (object.attachEvent) object.attachEvent("on" + evName, fnName); else if (object.addEventListener) object.addEventListener(evName, fnName, cap); } addEvent(window, "load", makeTOC, false); //the code to run makeTOC() function when the page loads var sections = new Array("h1", "h2", "h3", "h4", "h5", "h6"); //list of elements that act as section headings var sourceDoc; //document on which the TOC is based function makeTOC() { var TOC = document.getElementById("toc"); //html codes added to the TOC object.

My instruction is to :"format the row in the table so that they alternate from white to grey. Within the grey rows format the text to white, Withing the white rows, format the text to black. I created a table for this in a previous exercise which I'll paste in the bottom. If I understand correctly, I need to use the table's <tr> element, but I don't know how it should be formatted. Any suggestions would be greatly appreciated. Here is what I got so far; <form action="" name="newsHeadlines"> <table border="0" width="100%"> <tr valign="top"> <td> <select name="headline" multiple="multiple" style="height: 93px"> <option onclick="document.newsHeadlines.news.value=newsItem1"> Investigation of building standards in quake zone </option> <option onclick="document.newsHeadlines.news.value=newsItem2"> Obama sees signs of economic progress </option> <option onclick="document.newsHeadlines.news.value=newsItem3"> Apple aplication downloads approach 1 Billion </option> <option onclick="document.newsHeadlines.news.value=newsItem4"> Jones, Braves beat winless Nationals 8-5 </option> <option onclick="document.newsHeadlines.news.value=newsItem5"> America's uninsured haven't shown collective power </option> </select> </td> <td> <textarea name="news" cols="50" rows="10" style="background-color : Transparent"></textarea> </td> </tr> </table> <script type="text/javascript"> /* <![CDATA[ */ /8 ]]> */ var newsItem1 = "Example1"; var newsItem2 = "Example2"; var newsItem3 = "Example3"; var newsItem4 = "Example4"; var newsItem5 = "Example5"; </script> </form> I have a few buttons on a page I'm developing and I want the onclick event to call a javascript function in an external file and execute it. I would like to be able to pass a parameter to that function and then either have the function take the user to a new URL or make changes to the webpage content. Initially (just to test) I had inline javascript that caused an alert to popup. That worked fine. Next I took the inline code and put it in a function in an external javascript file that was referenced in the HTML: Code: <script type="text/javascript" src="../assets/js/ews-js.js"></script> <a link="www.xx.com" class="sk-shop-button" onClick="onclick_shop_button">Shop for Supplies</a> The function is as follows: Code: function onclick_shop_button() {
window.alert('Life Is Good!');
return false;
}
When I attempt to call it this way nothing happens. I'm guessing I should not be using a link there since I have to build the URL inside the Javascript (for now though the Javascript is just showing an alert). In one use case I want to be able to pass a parameter which would contain a product name so the function could load the correct webpage. So the function would have to build the URL using the product name as part of the URL then load that page. In a different use case (for a different button) the user would click on an EDIT button that would then update parts of the webpage allowing the user to click on areas to delete content. I am not sure how to implement either use case. I know I can use CSS to modify the look of the webpage and then use subsequent onclick events to do the deleting but am not sure how to delete HTML from within Javascript. Same with how to go to a new URL from within Javascript. Finally I am not sure why the inline Javascript works but the external does not. Any help would be GREATLY appreciated! Hi, I am just beginning out with Javascript and trying to complete a simple login page.

Here is the script & form: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>JSLEARN</title> </head> <SCRIPT language = "javascript"> var currency_rates = new Array(); currency_rates["GBP"]= 1.60132; currency_rates["CAD"]= 1.00002; currency_rates["EUR"]= 1.39752; currency_rates["AUD"]= 1.04824; currency_rates["JPY"]= 0.01315; function getCurrencyRates() { var currencyRates=0; var theForm = document.forms["jslearnform"]; var selectedCurrency = theForm.elements["currency"]; currencyRates = currency_rates[selectedCurrency.value]; return currencyRates; } function calculateTotal() { A = parseFloat(document.jslearnform.insert.value); X = A * getCurrencyRates() document.jslearnform.total_USD.value = X; } </SCRIPT> <body> <form name="jslearnform" method="post" action=""> <table width="66%" border="0" id="form_table"> <tr> <th width="41%"> <p>Insert ›</p></th> <td width="59%"><p> $ <input type="text" size="7" id="insert" name="insert"> <select id="currency" name="currency" onchange="calculateTotal()"> <option value"GBP">GBP</option> <option value"CAD">CAD</option> <option value"EUR">EUR</option> <option value"AUD">AUD</option> <option value"JPY">JPY</option> </select> <br> </p></td> </tr> <tr> <th>TOTAL ›</th> <td><strong>US$</strong> <input type="text" style="background-color: #DCDDDD;" size="14" id="total_USD" name="total_ USD" value="" /></td> </tr> <tr> <th> </th> <td> <input type="button" value="Calculate" onClick = "javascript:calculateTotal()"> <input type="reset" value="Reset"> </td> </tr> </table> </form> </body> Not much programming experience, but some C++ and Python. I would like to make a web page that 1. flashes and image for 1 second 2. flashes a a pair of images for 1 second 3. displays an image and waits 4. Wait for a certain correct keystroke to be entered. 5. Repeat 1-4 a few hundred times. ^The above would iterate through a loop, say of 300 counts, and sub-iterate through an array of images, say 30, going through all 30 images 10 times for example. Oh, and the array elements would be displayed in random order. Also, I would like to keep track of errors (wrong keystroke) and time it took to enter correct keystroke. I would prefer that this webpage work on the iphone, even older ones. Java is limited on iphone? I tried playing a Java chess game and had no luck on iphone. So, would I be able to do this using Javascript? If not, Java would be best? As I said, I would prefer iphone compatibility, but it is not required. I just want to know which one I should use before I bury my nose in a book about programming Java or Javascript. I'm building a website to catalog a history of college football uniforms, and having something like this on several of the pages would be extremely helpful. I've been told that making it in Javascript instead of Flash would be better for my website. I've also been told that it should be relatively easy to write the code for it. In short, I want to be able to take the parts of this image and allow viewers of the site to be able to switch between parts to mix and match. There are quite a few teams with six or more possible uniform combinations, so I'd like to be able to do this for the site. This would probably be a good way to get my start on learning at least some Javascript basics, so would anyone be willing to help me put this together? hello, is there a date format for an existing date? all I see is a var d = new Date(); but i need to format an existing date? thanks! |
