Please could anyone offer any advice, in simple terms on how to add anchor points to a page in order to create a smooth scroll element such as this one: http://www.kryogenix.org/code/browser/smoothscroll/#top Any help would be much appreciated. Hello: I have this js function: Code: <script type="text/javascript">
function updatesum() {
document.PaymentForm.newbalance.value = (document.PaymentForm.balance.value -0) - (document.PaymentForm.paymentamount.value -0);
}
</script>
I want to round the value of Code: document.PaymentForm.newbalance.value to two decimal points. May I request some assistance! Hi all, I have a boss who wants to show 5000 points on a Google map. So far, only a fraction of this being displayed freezes the browser. I've been challenged to make this possible while still in the realm of the browser. Would the flash version of Google maps api be a better bet? Does flash provide a better framework for this kind of heavy usage? Hi all, I am trying to wrap a text selection with BBCode. I have it working, but there is one final part I need help with. First, here's the code I'm using: Code: var range = ed.selection.getRng(true);
var s = ed.dom.create('span', {}, '');
range.surroundContents(s);
s.innerHTML = open + s.innerHTML + close;
ed.selection.select(s);
This is an explanation of each line: get the user's selection as a W3C compatible range create an empty <span> element surround the selection range with the span convert the selection from "selection" to "[bbcode]selection[/bbcode]" by using innerHTML select the new <span> element Of course, selecting the span ALSO selects the BBCode open and close tag... like in this pictu So, the last thing I need to do (the whole point of this post)... how do I MOVE the range start and end points so that only the selection is selected and NOT the whole thing? I will greatly appreciate if someone can tell me how to move those selection start and end points... Thanks! -- Roger Hi, I need a help with a project I am working on. I am not a developer so not so familiar with javascript. Suppose I have a map with ten junctions and based on that map, I need to calculate all the possible routes between one junction to another. How do I represent the map in javascript and how do I code the function to calculate all the possible routes?? :-( many thanks if someone can help me hey. ok so i have a page with an input field where a user can input a name. when they do so it will bring back the postcode for that name and then display a marker on a google map in the correct place. unfortunately some of the names have more than 1 result which means it needs to plot more than 1 marker on the map...ive spent a lot of time on this but cant figure it out. can someone help me please? here is the code for my page so far. <head> <title> New Document </title> <meta name="Generator" content="EditPlus"> <meta name="Author" content=""> <meta name="Keywords" content=""> <meta name="Description" content=""> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html { height: 100% } body { height: 100%; margin: 0px; padding: 0px } #map_canvas { height: 50% } </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"> </script> <script type="text/javascript"> var geocoder; var map; function initialize() { geocoder = new google.maps.Geocoder(); var latlng = new google.maps.LatLng(52.63512, -1.68992); var myOptions = { zoom: 8, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); } function codeAddress() { var address = document.getElementById("address").innerHTML geocoder.geocode( { 'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { map.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: map, position: results[0].geometry.location }); } else { alert("Geocode was not successful for the following reason: " + status); } }); } </script> </head> <body onload="initialize()"> <form action="maptest.asp" Method="POST"> <!--query = "SELECT id, tx_postcode FROM staff WHERE Left([last_name],1) Like '"&request("name")&"' ORDER BY id asc"--> <!--#include file="../admin/dataconn/dataConnOmiga.asp" --> <!--#include file="../omiga/include/functions-omiga.asp" --> <% query = "SELECT id, tx_postcode FROM staff WHERE last_name LIKE '"&request("name")&"' ORDER BY id asc" if request("name")<>"" then set avail = dataconnOmiga.execute(query) if not avail.EOF then While Not avail.EOF Response.Write "<b>" & "<div id=""address"">" & (avail("tx_postcode")) & "</div>" & "</b>" avail.MoveNext wend response.write "<input type=""button"" name=""submit"" value=""Plot on Map"" onclick=""codeAddress()"">" & "<br><br>" Response.Write "<BR>" end if ' Close the Recordset object and destroy it avail.Close Set avail = Nothing end if %> <!--#include file="../admin/dataconn/dataConnOmigaClose.asp" --> <input type="text" name="name" value=""> <input type="submit" name="submit" value="Search for Staff"> <div id="map_canvas" style="width:50%; height:50%"></div> </form> </body> ive never came across api's before and im very new to this so the more detailed you could be the better Hello, I am in the process of using the split function for splitting strings into an array. The problem I am dealing with is how to do this with local language. Not all languages us the space " " delimiter between words to write a phrase or sentence. I have a list of all of delimiters for english, japanese, chinese, korean in Decimal Code Point format. For example, the decimal code point equivalent for " " is 32. Is it possible to use the javascript split function with decimal code points? If not, how can I reformat them into a format that js would understand? Many thanks. This is the code that I'm presently using: Code: <script language="JavaScript" type="text/javascript">

However, what this piece of code does is that, every radio button gets only 1 point. What I intended is that every subsequent radio button in each <td> garners incremental points by 1. Eg: Q1, 1st radio button gets 0pt, 2nd radio button gets 1pt, 3rd radio button gets 2pt. Does anyone have any idea how to implement that, all help are greatly appreciated! |
