Having searched around, most are either too big or too simple. I did find "one" that I liked but it links to a lame page. I would rather have no link rather than the one provided. The widget I like is a simple javascript "include file" similar to this one: http://www.gooplusplus.com/external_wx._js Code: // This javascript file is normally dynamically CRON generated
// but for this test, we will just use static values.
document.write(''+
'<a href="http://www.gooplusplus.com/g5.php?p=X&s=box#FAKE-WEATHER-SITE">'+
'<div class="wxbox"> <img class="wximg" alt="Clear" title="Clear"'+
' src="http://newcityvegas.com/pics/nightmoon.png" /> '+
' <div class="wxtemp" title="Temperatu 73°F (23°C)">73°F</div>'+
' <div class="wxvis" title="Visibility: 10 miles">10 miles</div>'+
' <div class="wxother"'+
' title="Wind: Calm, Pressu 1008 hPa (29.76 in Hg), Humidity: 47%">'+
'Wind: Calm<br />Pressu 29.76 in<br />Humidity: 47%'+
'</div></div>'+
'</a>');
I tried to change the (first and only) HREF URL to a NULL value like this: document.getElementsByTagName('a')[0] = null; It did not work and I have not figured out an alternate method. My working test page is he http://www.newcityvegas.com/weatherbox.html with source code below. Any suggestions? Code: <html><head>
<link rel="STYLESHEET" type="text/css" href="weatherbox.css">
</head><body>
<script type="text/javascript"
src="http://www.gooplusplus.com/external_wx._js"></script>

{
// trying to reassign HREF url
var firstHREF;
var newURL='http://intellicast.com/Local/Weather.aspx?location=USNV0049#subnav';
firstHREF = document.getElementsByTagName('a')[0];
document.write("<font color=red>document.getElementsByTagName\('a'\)\[0\] \=\= </font>");

Hey guys, I'm using a script that has the back-end functionality mashed up so I can't change it. An image with a link around it hides behind this: $RateUserThumbnailLink$ And i'd like to disable the link somehow as the owner wants money for the edit which is ridiculous. Can anyone figure out a way of disabling the link it generates? Hello! I'm currently working on trying to target an anchor based on what the contents of their 'title' attribute is, then apply a href to that anchor. Here is what I have so far Code: function(j){
$meh = $('a#mapThisLocation');
if ($meh.attr('title' == '192-dodge')){
$meh.attr('href', 'http://www.google.com')
}
};
the current html of that anchor when the page loads follows. Code: <a id="mapThisLocation" title="192-dodge"> any thoughts? Hi guys, Having a little bit of trouble with a site I'm currently working on... I'm using some AJAX for the instant g-mail/facebook style navigation, you know the kind, with no refreshes, etc. Problem is, to allow for back/forward and bookmarks, I currently use a URL that looks like: http://www.mySiteOfFun.com/index.html#page=news.html; This is fine, not a problem... The issue comes into play when I want to open up the news.html page, from my home.html page, and have it open to news item #6 (for example). I can't add a #, because one is already being used to reference the anchor for the content div. Has anyone run into a similar problem before? If so, how did you resolve it? Can some jQuery be used to find the location of the news item div in question, on load, and scroll to it like that? Just not sure how to progress really, and any help would be greatly appreciated! Hello all, I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine, thankfully. However, I am stupidly suck trying to validate the form on the client side with a JavaScript function before the form is submitted. Here is my index.jps: Code: <%--

Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given. Am I correct in calling the function onClick?

Hi, I'm using the following Javascript code to show a div layer depending on the URL Code: <script type="text/javascript">
if (location.href.match(/folder/)) {
document.getElementById("div-layer").style.display="block";
}
</script>
This works perfectly when I visit http://www.domain.com/folder but I do not want it to match any subfolders beneath /folder, for example: http://www.domain.com/folder/sub-folder http://www.domain.com/folder/sub-folder2 etc. Does anyone know how I can modify the code to only match /folder or /folder/ and no subfolders beneath it? Thank you in advance. Hey friends, I'm writing a program but I'm having issues. I need to write a program that asks for 3 different numbers (prompt boxes) and determine which number entered was the highest and the 2nd highest. I know what to do for the input and output but I don't know what to do during the processing.
Hi, I am trying to write a small javascript program where I can call the following two functions and store information which a user enters. The problem is if I call the function a second time to add more information the array gets overwritten. info () insert (name, surname, favouriteColour) function info () { name = prompt ("Please enter your name."); surname = prompt ("Please enter your surname."); favouriteColour = prompt ("Please enter your favourite colour."); } function insert (name, surname, favouriteColour) { var info = new Array (); info.name = name; info.surname = surname; info.favouriteColour = favouriteColour; return info }; Help is really appreciated.. Hello Everyone, I am inexperienced in JavaScript. I have an html page with several numeric input fields which are an array. At the bottom of the screen is a running total of the numbers entered. The html is like: <INPUT TYPE=TEXT NAME='array[0]' onchange='addup()'> <INPUT TYPE=TEXT NAME='array[1]' onchange='addup()'> etc..... <INPUT TYPE=TEXT NAME='array[9]' onchange='addup()'> <INPUT TYPE=TEXT NAME='arraytotal'> The javascript is: function addup() { var total = 0; for (var i=0; i<=10; i++) { total += Number(document.forms["formname"]["array["+i+"]"].value); } document.forms["formname"]["arraytotal"].value = total; } This works ok, but I don't want the field arraytotal to be an input field. How can I do this please? I have the following code that I wrote myself (except for the function isNumberKey). However, I don't know how to actually add the numbers together. My plan is to store the value entered in the forms as a variable, then manipulate the variables to get my final number. The final number would be stored in variable named Total and would be displayed after Total: at the bottom of my page. Could anyone help me? I can provide additional information if you need it. Code:

<!--
Price = oForm.elements["price"].value;
Quantity = oForm.elements["quantity"].value;
Subtotal = oForm.elements["subtotal"].value;
Shipping = oForm.elements["shipping"].value;
function isNumberKey(evt)
{
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
}

Hello! First off, please excuse my ignorance. I am a bit new to the coding world. I want users to be able to enter data into a textbox on my site, and the data then be placed at the end of a specific url, followed by '.html'. For example, say my website is mysite.com. If someone enters in the word "John" in the textbox and clicks the 'Submit' button, the URL should now be: mysite.com/John.html Thanks in advance! Hi everyone, new here. I'm trying to write a program that displays what a user has entered, it processes it, and displays it backwards This is what I have so far, Code: <script type="text/javascript">
var input ("Please enter a sentance","")
So really this is what it needs to display. "The sentance you entered are "Hi people"" "The sentance in REVERSE order are "elpoep iH" If anyone can help, it would be awesome, since I'm a noob at this. Hello, I have a form that works out some basic math questions e.g. area etc. I run a function when a form field is updated to do the calculations, however I'd like to run a different calculation depending on which form element was updated. Is there a way to say something like: if (area1 was updated) { work out this calculation } if(area2 was updated) { work out this calculation } and so on? Thanks, Nicola Hello, I am not well-versed with javascript. Actually i have some calculations has to be displayed in total (textbox) as soon as i enter the values in other text box. I have done that. But if multiple rows added (its dynamically added ) that code doesn't work for 2nd row or 3rd row... I don't know how to do it. Here is my form where i am entering data and displaying result Code: <input type="text" class="span2" name="item[]" id="category" value="<?php echo $row1['item'];?>" />
<input type="text" class="span1" name="uom[]" id="category" value="<?php echo $row1['uom'];?>" />
<input type="text" name="description[]" id="category" value="<?php echo $row1['description'];?>" />
<input type="text" class="span1" name="quantity[]" id="qty" onkeyup="getValues(1)" />
<input type="text" class="span1" name="price[]" id="price" value="<?php echo $row1['selling_price'];?>" onkeyup="getValues(2)" />
<input type="text" class="span1" name="discount[]" id="discount" value="<?php echo $row1['discount'];?>" onkeyup="getValues(3)" />
<select name="tax[]" class="span1" id="tax" onkeyup="getValues(4)">
<option value="<?php echo $row1['tax'];?>"><?php echo $row1['tax'];?></option>
<?php $l1 = mysql_query("select * from taxes") or die (mysql_error());
while($l2 = mysql_fetch_array($l1))
{ ?>
<option value="<?php echo $l2['rate']; ?>"> <?php echo $l2['name'];?> - <?php echo $l2['rate'];?>% </option>
<?php } ?> </select>
<input type="text" class="span1" name="freight[]" id="freight" onkeyup="getValues(5)" placeholder="Freight" />
<!--<input type="text" class="span1" name="freight_tax[]" id="frtax" placeholder="Frt Tax" /> -->
<input type="text" class="span2" name="total[]" id="total" />
And java script Code: <script language="javascript">
function getValues(val){
var numVal1=parseInt(document.getElementById("qty").value);
var numVal2=parseInt(document.getElementById("price").value);
var numVal3=parseInt(document.getElementById("discount").value);
var numVal4=parseFloat(document.getElementById("tax").value);
var numVal5=parseFloat(document.getElementById("freight").value);
var sub_total = (numVal1 * numVal2) - numVal3;
var subt_tax = sub_total * (numVal4/100);
var total = parseFloat(sub_total + subt_tax);
var totalValue = parseFloat(total + numVal5);
document.getElementById("total").value = totalValue;
}
</script>
It will be best to use server side scripting like php for it , because user can disable his javascript in that condition your code won't work
Brand new to the forum, so first off... Hello all!! I have been working on a project which randomly changes the text font of a word submitted (Color and Size). At present the code works fine, using the below Javascript. Code: <SCRIPT LANGUAGE="JavaScript">
function randomise(){
var words=document.myform.wordlist.value;
var spacer="";
words=words.split(document.myform.randomiseby.value)
document.myform.code.value=" ";
var colourscheme=new Array("0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F")
for(var time=0;time<=(words.length-1);time++){
{var c1=Math.round(Math.random()*(colourscheme.length-1));
var c2=Math.round(Math.random()*(colourscheme.length-1));
var c3=Math.round(Math.random()*(colourscheme.length-1));
var c4=Math.round(Math.random()*(colourscheme.length-1));
var c5=Math.round(Math.random()*(colourscheme.length-1));
var c6=Math.round(Math.random()*(colourscheme.length-1));
var size=1+Math.round(Math.random()*6);
document.myform.code.value+="<font color=\"#"+colourscheme[c1]+colourscheme[c2]+colourscheme[c3]+colourscheme[c4]+colourscheme[c5]+colourscheme[c6]+"\" size=\""+size+"\">"+words[time]+"</font>"+spacer+" ";
}
}
looks_like.innerHTML=document.myform.code.value;
}
</script>
To really highlight the text i would like to keep the font white and change the background colour but i don't have a clue how to do it... Please note: i am a complete noob to Javascript and the above code has been bodged together from a number of tutorials. Can anyone help? Hello! I need some help here. I need to pre-populate a name and a phone number box based on what's entered in the employee id box. By entering in the employee id - EMPLOYEE ID: [JOHN R] It automatically fills in - Employee Name: [John Roberts] Employee Phone: [1234567890] Thanks.
