JavaScript - Retrieving Xml From Javascript
I think this is a relatively simple problem, instead of hard coding the latitude and longitude in map.setCenter I need it to read it in from an XML file, like the the markers do below (.getAttribute("lat") and .getAttribute ("lng")).
I hope this makes sense, I've tried changing the code around but I can't seem to make it work. Any help appreciated. Code: // create the map
var map = new GMap2(document.getElementById("map"));
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng( 49.4008,1.4941), 5);
// Read the data from example.xml
GDownloadUrl("example.xml", function(doc) {
var xmlDoc = GXml.parse(doc);
var markers = xmlDoc.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
// obtain the attribues of each marker
var lat = parseFloat(markers[i].getAttribute("lat"));
var lng = parseFloat(markers[i].getAttribute("lng"));
var point = new GLatLng(lat,lng);
var html = markers[i].getAttribute("html");
var label = markers[i].getAttribute("label");
// create the marker
var marker = createMarker(point,label,html);
map.addOverlay(marker);
}
Similar TutorialsHello all, Sorry if this may seem like a silly question, I have searched but not really to sure how to word what I am searching for as I don't know if I am going the right way around it! Basically, I am looking to insert a keyword in to a javascript alert box when someone visits my website, so say they came from codingforums.com, it would say "Welcome, CodingForums.com Visitor". My keyword will be passed from the ad platform I am working with and shows up correctly in the tracking, so I'd imagine it's just a case of having the snippet of code for it to show in the alert, correct? If there is no keyword, I would just like it to say "Welcome Visitor" or something. How do I go about this? Thank you in advance for any help.

My question is, I've been spending countless hours trying to: 1. Make two radio buttons indicating "No" and "Yes", 2. Retrieve which selection the user has made, 3. Change the value of "bugDiscount" or the amount of money ($20 or $0) depending on which choice the user made; $0 for No & $20 for Yes. 4. Subtract the value of bugDiscount (0 or 20) from the totalCharge to get TotalDue I know I'm close, but I've tried any number of variations in my code and I still can't seem to get it right. Can anyone help? I had post this problem before, dealing with the shopping cart application. The application so far does everything that i would like it to do. I'm able to store and retrieve the cookies. But right now, my problem is extracting the individual values from the cookies and placing them into a table i have created. This is the format of the cookie when retrieved. ItemName = quantity$price. what i am trying to do is retrieve the quantity and price values from the cookie, and display that data into my table. the cookie is being created in my store page, and then retrieved and displayed in my cart page. here is the code for my store page store.html Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

the values that are supposed to be retrieved in the table are invoked using the onload event attribute which is suppose to call the retrieve() function. I am a beginner. I am trying to create a script to randomly assign recipients to givers for a Secret Santa. The participants are placed into groups. A giver cannot be assigned a recipient with whom he is grouped. I want to return all of the assignments in a table. I have made the following script. When I run it, it seems to get stuck in a loop. Any ideas why this might be? If you have any questions about how I want this thing to run, feel free to ask. Your help would be greatly appreciated. Code: <html>
<head>
<script type="text/javascript">
var giver = new Array();
giver[0] = new Array("CL","BL");
giver[1] = new Array("LP","JP","BP");
giver[2] = new Array("JO","MO");
giver[3] = new Array("JC","TC");
var recipient = new Array();
recipient[0] = new Array("none","none");
recipient[1] = new Array("none","none","none");
recipient[2] = new Array("none","none");
recipient[3] = new Array("none","none");
var string = "<table><tr><td>Giver</td><td>Recipient</td></tr>";
function chooseRecipient() {
var x;
for (x in giver) {
var y;
for (y in giver[x]) {
var a = Math.floor(Math.random() * giver.length);
while (recipient[a].indexOf("none") < 0 || a == x) {
a = Math.floor(Math.random() * giver.length);
}
var b = Math.floor(Math.random() * giver[a].length);
while (recipient[a][b] != "none") {
b = Math.floor(Math.random() * giver[a].length);
}

HI I have set up a page passing information.. eg anything.htm?the text and I am trying to retrieve it into a form field ie pre fill a box. What I cant seem to work is to get the text after the ? into prefilled text for the field I can print it with document.write. I am trying to get it into (or something similar) <textarea rows="4" name="products" cols="49"> XXXX here text after htm? XXXX </textarea>. Hope this makes sense and I appreciate any help and time. So basically, I have this side bar with a whole bunch of links and I wish to load content into a div directly across from it. The links will be hashes (eg example.com/#foo/bar), then the JavaScript loads the content either into a div and updates a SPAN with the page name. I only have the iFrame version so far, so can someone help me on how to improve this and actually load the content instead of an iFrame? So far I have this code: Code: <script>
function goto(url) {
if (location.hash != url) {
window.location = url;
document.getElementById("pgname").innerText = "loading...";
}
}
function setPage() {
var hash = location.hash;
if (hash=="#foo") {
document.getElementById('pgname').innerHTML = 'Foo';
document.getElementById('pglocation').innerHTML = hash;
window.frames['content'].location.href = "blablah/foo.php";
}
if (hash=="#foo/bar") {
document.getElementById('pgname').innerHTML = 'Foo</b> > <b>Bar';
document.getElementById('pglocation').innerHTML = hash;
window.frames['content'].location.href = "doo/moo/23.htm";
}
}
</script>
<body onhashchange="setPage();">
<a href="javascript: goto('#foo')">foo</a><br />
<a href="javascript: goto('#foo/bar')">foobar</a><br />
<a href="javascript: alert(location.hash + ' || ' + location);">Info</a><br />
<a href="javascript: goto(location.hash);">Goto</a><br /><br />
<b><span id="pgname">Home</span></b><br />
example.com/<span id="pglocation"></span><br />
<iframe id="content" src="index.php" />
Hi, I'm new to this forum so please forgive me on any errors I may have made. I am working on a simple site for the company that I work for that allows a customer to input a 5 digit code in and returns what prize they have won. I found some code on a website which done the trick but it doesn't work in Chrome and Safari. My Javascript knowledge is extremely limited but I think I've narrowed it down to the "document.implentation.createDocument" line although the few fixes I've found, I can't get to work. Here is the code I have at the moment before I applied the fixes (this works in FF and IE). Code: <script type="text/javascript">
window.onload = loadIndex;
function loadIndex() { // load indexfile
// most current browsers support document.implementation
if (document.implementation && document.implementation.createDocument) {
xmlDoc = document.implementation.createDocument("", "", null);
xmlDoc.load("results.xml");
}
// MSIE uses ActiveX
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.load("results.xml");
}
}
function searchIndex() { // search the index (duh!)
if (!xmlDoc) {
loadIndex();
}
// get the search term from a form field with id 'searchme'
var searchterm = document.getElementById("searchme").value;
var allitems = xmlDoc.getElementsByTagName('item');
results = new Array;
if (searchterm.length < 4) {
alert("Please re-check and enter your 5 digit code");
} else {
for (var i=0;i<allitems.length;i++) {
// see if the XML entry matches the search term,
// and (if so) store it in an array
var name = allitems[i].lastChild.nodeValue;
var exp = new RegExp(searchterm,"i");
if ( name.match(exp) != null) {
results.push(allitems[i]);
}
}
// send the results to another function that displays them to the user
showResults(results, searchterm);
}
}
// Write search results to a table
function showResults(results, searchterm) {
if (results.length > 0) {
// if there are any results, write them to a table
document.write('<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>Untitled Document</title><link href="cno-competition.css" rel="stylesheet" type="text/css" /></head><body>');
document.write('<div id="container"><div id="logo"></div><div id="prizeContent"><img src="media/new-york.jpg" width="750" height="500" alt="New York" />');
for(var i=0; i<results.length; i++) {
document.write('<h1>Congratulations</h1><p>You entered prize code <b><i>'+searchterm+'</i></b> and have won a <span style="font-weight:bold; color:#75ACC1">' + results[i].getAttribute("prize") + '</span>.</p>');
}
document.write('<p>To claim your prize please contact the Complete Night Out team on 01908 544445.</p>');
document.write('</div></div></body></html>');
document.close();
} else {
// else tell the user no matches were found
var notfound = alert('No results found for '+searchterm+'! Please re-check and enter your 5 digit code');
}
}
</script>
The fix I found added the below into the code but I couldn't get it to work using this. Link here. Code: var xmlhttp = new window.XMLHttpRequest();
xmlhttp.open("GET","results.xml",false);
xmlhttp.send(null);
xmlDoc = xmlhttp.responseXML.documentElement;
Any help would be much appreciated. If you would like to see the site live please click here Thank you. Kishan Hello! I am trying to find a script that allows you to open multiple browser tabs and then close each of those tabs, either one by one or all at once. Does anyone know how to do this please? Thanks so much for your help. I want to have another go at Javascript. I have several books on the subject but I find that my eyesight is a major problem. Therefore I want to try an on-line solution, preferably free. I have Googled, but there are so many that I am almost dizzy with the choices. Perhaps someone could recommend one. Not too fussy visually. My knowledge is VERY basic. Frank Does anyone know how to make URL links that use Javascript still work when users have Javascript disabled on their browser? The only reason I'm using JS on a URL is because my link opens a PDF file, and I'm forcing it not to cache so users have the latest version. I tried the <script><noscript> tags, but I'm not sure if I'm using it correctly, as my URL completely disappears. Below is my HTML/Javascript code: <p class="download"> <script type="text/javascript">document.write("<span style=\"text-decoration: underline;\"><a href=\"javascript:void(0);\" onclick=\"window.open( 'http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf?nocache='+ Math.floor( Math.random()*11 ) );\" >The Child Magazines Media Kit</a></span> (PDF 1 MB) ");</script> <noscript><span style="text-decoration: underline;"><a href="http://www.webchild.com.au/mediakit/Direct_Media_Kit_Web.pdf" >The Child Magazines Media Kit</a></span> (PDF 1 MB)</noscript> </p> Thanks for any help, Michael Hi Guys, I am new at JavaScript and start to do some tutorials.What I am trying to do here is prompting user to input a name and if the name was valid the page(document) will display with all objects like the button.But if user enter a wrong name then the button will be disabled!

And this is how I want the format of the function to be: function testsession() { if there is a session called 'hiredate' { activate the script above } else { var el = document.getElementById("product_data"); } } I just dont know how to write this in javascript Could you help me if possible please I want to insert this js snippet Code: function addText(smiley) {
document.getElementById('message').value += " " + smiley + " ";
document.getElementById('message').focus();
return false;
}
to a loaded iframe with name&id chtifrm. I can access it & change embed something in its html via using something like: Code: $(parent.chtifrm.document.body).append('<div id=\"smly\" style=\"cursor:pointer;float:left;top:200px;display:none;position:absolute;\"><\/div>');
.... Code: parent.chtifrm.document.getElementById('chatbox_option_disco').style.display == 'none'
but how do I insert js in the head of loaded iframe? I got an index.php Code:
<html>
<form action="bacakomik.php" method='post'>
<select name="kodekomik">
<option value='../komik1/|23'>Judul Komik1</option>
<option value="../komik2/|20">Judul Komik2</option>
<option value="../komik3/|10">Juduk Komik3</option>

<input type="submit" />
</form>
<?php

echo ('<option value= "'.$i.'">'.'Page '.$i.'</option>');
echo ('</select>');
?>
</html>
As you can see, each of the option brings specific value "../komik1/|23" komik1 is a directory | is a delimiter 23 is the pages in one chapter and can be considered also as how many images are there on a specific directory This is my bacakomik.php Code: <?php

<img src="img0.jpg" id="im">
With the current code on bacakomik.php, I only can change the img src of id "im" in the same directory only. What I want is that the Javascript could "add" the "$exploded[0]" variable so that the picture can be loaded from different directory. Anyone can do this? I believe that the fix should be somewhere on input tag inside OnClick, or do you know where? Anyway, I found this on the net http://p2p.wrox.com/php-faqs/11606-q...avascript.html Please help me to those who can... Hey, I've got to make the values of some textboxes change the co-ordinates of my sprite on a canvas and havent a clue on how to do it, Here is my form with the two textboxes and submit button: <form> x: <input type="text" name="x" /><br /> y: <input type="text" name:"y" /><br /> <input type="submit" value="Submit"/><br /> </form> And i need it so that they change the values of these: //this shows where my sprite will start on the canvas var block_x; var block_y; searched the internet for hours and cant really find anything i understand or works. any help is much appreciated All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero I wrote a log function that took note of various function calls. Thinking that functions are first class objects, and objects have properties, I made the name of each logged function a property of that function, e.g., brightenInnerPara.name = "brightenInnerPara"; Every browser I tried (Firefox, MSIE, Opera, Chrome, Safari) accepted the assignment, no problem. In Firefox and MSIE, the result was what I wanted: brightenInnerPara.name == "brightenInnerPara" But in the others, the result was: brightenInnerPara.name == null Question 1. Which Javascript is correct here? I favor Firefox and MSIE, not merely because they were willing to give me what I wanted, but also because it makes no sense to accept an assignment statement without throwing an error and then give it a null semantics, like Chrome, Opera, and Safari did. I found a workaround, using assignments like this: brightenInnerPara.prototype.name = "brightenInnerPara"; To my surprise, that worked in every browser. But I don't know why. It seems that such assignments are enough to cause each function to have its own distinct prototype. Question 2. Just how inefficient is my workaround, and why does it work? 1st part i have a main jsp page with some values. For example 5 text boxes and one submit button. When i click on the submit button a popup form should generate with a list box. when i select a value from the listbox the value should be transferred to the main jsp(say in 5th textbox )and 2nd part along with these 5 values the control should transfer to another jsp. i am able to do the first part but second part is not getting. Thanks in advance. |
