JavaScript - Google Map Speed Up
Hello. I have a problem. I use google map to show some points. I have to show all points for some region, and number of points gets to 4.000. So it takes some minutes to show all points.
I use gif image-> size: 400 bytes I found http://fundrace.huffingtonpost.com/ and it takes only couple of seconds to load more 1000 markes. Does someone know how to resolve this? Thanks Similar TutorialsHello, I'm working on a rotator and I'm needing to slow it down. I think I would use var speed right? How would I use it in this script? <script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script> <script type="text/javascript"> $(document).ready(function() { $('.slideshow').cycle({ fx: 'fade' }); }); </script> Hi all, I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this Code: <div id="myDiv"></div>
...
function test() {
for (i=0 i<100; i++) {
var obj = document.create("div");
// do stuff to style div and set content
document.getElementById("myDiv").appendChild(obj);
}
// DO SOMETHING WITH ONE OF THESE DIVS
}
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access? I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times. The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch. Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away. Any information much appreciated, I hope I have been clear enough. I'm using IE7 and so are the testers. Thanks, Dale I have this horizontal news ticker which works just perfect in ie7 regarding to speed, but when looking at the same page in ie8 the speed is very slow... Has anybody else encountered this, and if yes... How do I solve this? Code: initialize: function(element, options) {
this.setOptions({
marHeight: 18,
marWidth: 565,
steps: 20,
speed: 20,
direction: 'left',
pauseOnOver: true,
pauseOnContainerOver: true
}, options);
this.timer = null;
this.textElement = null;
this.mooqueeElement = element;
this.constructMooquee();
}
Thanks in advance :-) I have a piece of raw code. I want to make some images greater/smaller onmouseover/onmouseout, in a graduate mode, on using some independent setTimeout objects which are to be started/clear . It works ok if the mouse goes up and down at a reasonable speed. But if the movement is fast, the onmouseout looks to fail in firing (and some images remain on their bigger stage), which is somehow weird. Where could be the mistake? What did I make wrong (except that I might have had done that with Flash)? Any thoughts? You have in the attachment (see test.zip) the full example, with the used images, as well.

In the home page (index.html) i have a flash intro. The first time a user sees the website, the intro should play. Once he goes to another page (about_us or contact_us) and comes back to the home page, it should show a different swf (the version without the intro) - i have created two swf files. I need to know how to change them when the user has already seen the intro or was in the home page before. When i googled, i found something on cookies. I have no clue on how to set them and change the swf file. Would be great if someone has already done this or point me to a tutorial. i need java script. please help!!!!!!! i need script will detect connection speed and redirect to a page:
Hello Experts, I did a website & I am having trouble wit it. In IE8, FF& Chrome, the site works perfectly. But in IE7, the site slows down very much that even the link hover effect doesn't show properly. I believe its some kind of javascript or Ajax request which is causing such delay. Can you guys please help me sort this out.... Here is the site with functionality... http://tinyurl.com/3qkunvy Here is the site without functionality but just the gallery is integrated... http://tinyurl.com/439ejhk The speed was even better before the Ajax is applied for contents. Any solutions/fixes please... was wondering if it made sense to optimize the comparison order inside an if() statement if one of the comparison targets is a function call eg: Code: var a = true,
b = function() {return false;};
if (b() || a) {...}
if (a || b()) {...}
would the second statement run faster because it would theoretically never need to call b() in this situation? can the eval order be relied on? does this depend on the js engine/internal optimizations? thanks, Leon I have a page with a GoogleMap with a GoogleBar and I would like the GoogleBar to appear with something written in it already and to have that search executed. In other words, I would like to "write something to the GoogleBar and press Enter" automatically as soon as the map loads. How can I do this? btw: By GoogleBar, I mean the search bar that appears on the map after using the enableGoogleBar() function. Hello good coders! Thanks to the wonderful script provided by coothead he http://www.codingforums.com/showthread.php?t=87036 I was wondering how I could adjust the transition/fade speed between the images in the script? I tried a couple of different ways, but I couldn't get it working. Does anyone know how I can adjust this in a cross-browser compatible way?

Hi, I'm not sure where I have translated this incorrectly. I have one google map embedded on my page which works fine. But I wanted to add a second one. I thought the easiest way to do this would be to have a second page which is called later on with all the details on it for the second map. However although I think (this I presume is where I went wrong) I have replicated the instructions correctly the place holder for the second map just remains blank. This is the code for my called page with the instructions for the second map: PHP Code: <?php echo $_POST['Map'] . '<br />'; ?> <div id="placemap_canvas"></div> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> html {height:250px} body {height:250px} #placemap_canvas {width:100%; height:150px;} </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true" /> </script> <script type="text/javascript"> var latlng = new google.maps.LatLng ( <?php include("dbconnect.php"); $result = mysql_query("SELECT * FROM regions WHERE RegionPId='{$_POST['Map']}'"); while($row = mysql_fetch_array($result)){ echo $row['maplink']; } mysql_close($con); ?> ); var myOptions = { zoom: 4, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("placemap_canvas"), myOptions); } </script> And this is the script of the main page, just in case I would be better off keeping them both in one place. Code: <head>
<script type="text/javascript">
function loadSubPlace(File,ID,Msg,Eile,EID,Esg){
loadXMLDoc1(File,ID,Msg);
var mimer = setTimeout(function(){loadXMLDoc1(Eile,EID,Esg)},5000);

$tigerlilly=$row['RegionPId'];
echo '<input type="button" class="button3" name="place" id="place" value="' . $row['sub'] . '" onclick="loadSubPlace(\'getPlace.php\',\'txtHintPlaceSub\',\'hepatica=' . urlencode($wheat) . '\',\'getPlaceMap.php\',\'placemapcanvas\',\'Map=' . urlencode($tigerlilly) . '\');" />';

I've cut out the script that doesn't relate to this so I hope I haven't missed anything important. Can the Google API replace scraping? You can get blocked by Google if you scrape, but can you get the same info from the Google API at no risk?
I am making a dynamic google map and need to pass in a JS Object that has latitude, longitude, address, name, and a link. The JS Object will be getting those values from a DB and may have up to 15 recordsets. I need to know how to separate that out into it's entities to include in the Map API regardless of how many recordsets there are.
Hello guyz! I need to fetch some images whit custom sizes in Google Images, this is the API from Google that let me search end fetch images: Code: /*
* How to search for images and restrict them by size.
* This demo will also show how to use Raw Searchers, aka a searcher that is
* not attached to a SearchControl. Thus, we will handle and draw the results
* manually.
*/
google.load('search', '1');
function searchComplete(searcher) {
// Check that we got results
if (searcher.results && searcher.results.length > 0) {
// Grab our content div, clear it.
var contentDiv = document.getElementById('content');
contentDiv.innerHTML = '';
// Loop through our results, printing them to the page.
var results = searcher.results;
for (var i = 0; i < results.length; i++) {
// For each result write it's title and image to the screen
var result = results[i];
var imgContainer = document.createElement('div');
var title = document.createElement('h2');
// We use titleNoFormatting so that no HTML tags are left in the title
title.innerHTML = result.titleNoFormatting;
var newImg = document.createElement('img');
// There is also a result.url property which has the escaped version
newImg.src = result.tbUrl;
imgContainer.appendChild(title);
imgContainer.appendChild(newImg);
// Put our title + image in the content
contentDiv.appendChild(imgContainer);
}
}
}
function onload() {
// Our ImageSearch instance.
var imageSearch = new google.search.ImageSearch();
// Restrict to extra large images only
imageSearch.setRestriction(google.search.ImageSearch.RESTRICT_IMAGESIZE,
google.search.ImageSearch.IMAGESIZE_MEDIUM);
// Here we set a callback so that anytime a search is executed, it will call
// the searchComplete function and pass it our ImageSearch searcher.
// When a search completes, our ImageSearch object is automatically
// populated with the results.
imageSearch.setSearchCompleteCallback(this, searchComplete, [imageSearch]);
// Find me a beautiful car.
imageSearch.execute("Subaru STI");
}
google.setonloadCallback(onload);
But all I could find about restricted images sizes is this: Code: imageSearch.setRestriction(google.search.ImageSearch.RESTRICT_IMAGESIZE,
google.search.ImageSearch.IMAGESIZE_MEDIUM);
My problem is that I need custom fixes images sizes, not between a range of values like the above script was giving me... Google API reference says that: Code: google.search.ImageSearch.RESTRICT_IMAGESIZE - When this is specified as the value of type, the image search results will be restricted to images with certain pixel dimensions. Valid optional values for this type are as follows: * google.search.ImageSearch.IMAGESIZE_SMALL - restrict to small images, icons * google.search.ImageSearch.IMAGESIZE_MEDIUM - restrict to medium images * google.search.ImageSearch.IMAGESIZE_LARGE - restrict to large images * google.search.ImageSearch.IMAGESIZE_EXTRA_LARGE - restrict to extra large images Those who wants to play whit Google Playground, this is the link: Code: http://goo.gl/sPs2 Could some one help me get that images whit fixed sizes? Hi, Can anyone help define the difference between the 2 scripts below and help identify what is/should happen for each? Code: <script type="text/javascript">
var _gaq = _gaq || [];

Hello Everyone! I'm new to the forums but have a question with Google Translate I'm trying to add to my site. I believe the code for Google Translate is a Java Script and I'd like to put this on my website in the side column. The only thing I would like to modify is a <br> (break) between the Powered by and Google Translate. So I would like it to be center aligned like: Powered by Google Translate Right now it is stretching out the column because of the added space and frustrating me! Any idea how to do this? Here is the code: Code: <div id="google_translate_element"></div><script>
function googleTranslateElementInit() {
new google.translate.TranslateElement({
pageLanguage: 'en'
}, 'google_translate_element');
}
</script><script src="http://translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
My knowledge of javascript and coding in general is very very limited so any changes you make or where I should put the code, definitely let me know Thanks, Phil Hi guys, I'm trying to run this sample file that i got from the google docs.

my problem is i don't know how to execute it so i can see how it works. I tried sticking this code within a php file and it returns an error on the first line for unexpected t-string. So i tried changing the extension to xml and it just displays the code but does not execute. I'm stumped. Any help is appreciated. Thanks P.S. - Yes i do have the zend gdata framework installed and running on my server and is working correctly according to their test. Hi, I have just set up google analytics on my website but it is showing tracking unknown symbol in the status. Is it just the case of it taking time to set up or should it work straight away. Thanks Tyler |
