JavaScript - Mobile Development Question (jquery, Ajax, Html5 Related)
What would be the best way to get data for a mobile site. I've tried using Jquery $.ajax to bring in the data from a php file.
It seems to work however it takes some time to load without a way to really give a progress meter. I was wondering what the fastest way to do this would be. For instance it loads and loads then after a long while the alert(); pops up and the data loads into the page. Ultimately i was thinking i could use the ajax request to read in the data from the mysql database server, then transfer it to localstorage, im using HTML5 primarily for the development also just for reference. Somewhat new to mobile development i was just wondering if anyone had a starting point for me to look at and go from there. Code: $(document).ready(function($){
var dataret = 0;
$.ajax({
type: 'POST',
url: 'mobile.php',
beforeSend: function(){
$('#status').show();
},
success: function(data){
//initialize localstorage here
alert('success');
// if it takes as long as it does, a few minutes, at least show a loading bar...
$('#progress').progressbar({
});
},
dataType: 'json'
});
});
Thanks in advance! Similar Tutorialsi want to know how to Upload images or videos through drag and drop (jquery or html5 tools)
I am incorporating this menu into a site and for desktop users I need the mouseover. However, after referencing the link below for mobile devices (most management has Blackberrys). I am concerned the mouseover will not work on their phones. How do I add an option that will work on phones - like mouseover OR click option? http://www.quirksmode.org/m/table.html Thanks! I'm trying to finish off a NotePad/SketchPad app using the HTML5 canvas element and i am getting an error when i try to PUT image data to the canvas. also the getImageData() function for CANVAS is also not working. I would like to get this working soon, because i have a really nice Prototype of a 7 inch Touch screen device i would like to install this to. Error: canvas.putImageData is not a function according to all of the HTML5 canvas tutorials i've read (including the one on Mozilla-Dev), it should be correct, but it's still throwing this error. It makes no sense at all. I remember getting a similar error to this before by using the DOM element identifier - getElementByID() where the "D" is a capital letter when it should have been a lower case. However that doesn't seem to be the case here. Can anyone help me out with this? here's my HTML & JS code The main HTML UI file Code: <html><head>

so i have this "class" defined in a javascript file, "a.cross-link". This enables the ability for users to navigate the webpage in a slider format. it works fine if I directly place the required html code: Code: <a class="cross-link" href="#3" title="Go to Page 2">View Results</a> but if i have php print out that line for me, it doesn't work: PHP Code: echo "<a class= \"cross-link\" href=\"#3\" title=\"Go to Page 3\">$name</a>";( Where $name is some variable) Note: the php code is just your average sql stuff. here is an interesting observation i've made: if i "hardcode" this this into the html: <a class="cross-link" href="#3" title="Go to Page 3">View Results</a> and then i go to generate the sourcecode, this is what appears (this works): <A class=cross-link title="Go to Page 3" href="#3" jQuery1283131847233="30">View Results</A> but if i have the html made by a php echo statement, it just stays the same - i dont get a jQuery1283131847233="30" generated in the sourcecode. i'm sorry i'm having difficulty describing the problem. i'm new to jquery and ajax stuff. to me, it seems like the "cross-link" class i have defined in the javascript isn't being applied to correctly. i have no idea. can you invoke javascript from a php echo statement that is formatted to produce html code? here is another thing i believe is true: when the page loads, the javascript loads. the users, through the use of ajax, submitts a sql querey and navigates, using a jquery slider, to another div (where i want the user to go after selecting a resulting link from the sql query). so the javascript is going to execute before the list of results is produced. do I need to rerun the javascript each time new php produced sql data is populated in a div? if so, how? i dont know what more information you may need, so please ask. Thanks. I want to pass the "divId' function so that i can grab functions dynamically into the server where "success" is. this possible? I know the current setup is not (because " d.divId " isn't a variable) Code: function run(times,divId)
{
$(function()
{
var client_id = $('#client_id').attr('value');
$.ajax(
{
url:'http://urlhere.com',
data:{c:client_id},
timeout:99999999999999,
dataType:'jsonp',
jsonp:'callback',
jsonpCallback:'jsonpCallback',
error:function()
{
if (times==1)
{
run(2);
}
else
{
$('#'+divId).html('Error')
}
},
success:function(d)
{
$('#'+divId).html('$'+d.divId);
}
});
}

but that needs to change... I need to be able to drag an image from one browser window to a form text input in a different window, populating it with the image file name. I can do this easily, except that the result is the whole url, and I only want the filename to be inserted. In other words, it inserts http://www.path/path/file.jpg, but I just want to end up with file.jpg. I believe the file object .name property holds the info I need, but I don't know how to populate the input field with it. Any help appreciated. function sendValues() { var str = $("#myForm").serialize(); $.ajax({ type: 'POST', url: "/trying.php?avoidcache=' + myTimestamp();", data: str, cache: false, return:false }); } $(":checkbox[name='brand[]']").click(function() { $("#myForm").submit(); }); ..Upon reload, the values are serialized.. But when the page is done loading..the chosen values (checkbox) is not checked, I need it stay checked so I can add other values via checkbox to the url. here is a live demo.. http://vbizmarketing.com/trying.php Please help. Hey guys I should preface this by saying that this is not for my own site, or my own code; a friend has gone on holiday and needed this project fixing while he was away. Unfortunately my experience with jQuery is almost nil and everything was coded by someone else, so I'm really tearing my hair out. This is a Wordpress installation running Thematic with two child themes, one of which uses Ajax calls to grab page content. The issue is that the Ajaxified calls stop the swfObject content from being loaded. Compa http://dev.segolondon.com/wp292/media/ <- Flash content loads versus: http://dev.segolondon.com/wp292/#wp292/media/ If you take a look at the code of the two pages, you'll see there are no swfobject.embedSWF() calls on the Ajaxified page. It seems as though the jQuery calls are pre-empting the JS/Flash detection, so the swfObject code is never even written to the page. The actual custom, handwritten code (i.e. not from a library or a plugin) on this site is minimal, so I'm grasping at straws to fix this. I read somewhere about using a script block like this: Code: <script>
$(document).ready(
function() {
// Make the swfObject call
}
);
</script>
But I'm not really sure where to put it since there are so many plugins used, all with slightly different embed methods. Any help would be very gratefully received! right now I almost have this script working the way I want it to, here it is: Code: var hash = window.location.hash.substr(1);
var href = $('.workimg a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-5)){
var toLoad = hash+'.html #selected';
$('#selected').load(toLoad)
}
});
$('.workimg a').click(function(){
var toLoad = $(this).attr('href')+' #selected';
$('#selected').slideUp('slow',loadContent);
$('#load').remove();
$('#wrapper').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('normal');
window.location.hash = $(this).attr('href');
function loadContent() {
$('#selected').load(toLoad,'',showNewContent)
}
function showNewContent() {
$('#selected').slideDown('slow',hideLoader);
}
function hideLoader() {
$('#load').slideUp('slow');
}
return false;
});
How it works is an image is clicked, and it fills the #selected div with content. The problem I'm having is the #selected div is always visible so the questions I have are 1. How do I get this to snap to the #selected Div and add a 1 second delay before the slideDown effect? 2. How do I get add a fade in effect so it becomes Opacity=0 -> slideDown -> Opacity=1 when it appears and Opacity=1 slideUp -> Opacity=0 when it transitions to the next? Hi there, I am trying to make a view that stacks images on top of one another. As the user uses mouseup or mousedown (+ LMB click) the user can scroll through the images. I am trying to use Ajax to load the new image when the user mousesup. RIght now nothing happens on mouseup. Can someone tell me what I am doing wrong please? thank you. FYI: no errors on Firebug, hence I am posting here. Code: $("#filmviewer").mouseup(function(){
alert("t");
});
html Code: <div id="filmviewer" style="width:400px;"> <img src="pic_1.jpg" /> </div> The problem is when I click and mouseup over the image the alert("t") does not fire. what am I doing wrong? I am trying to perform an AJAX lookup during form validation onsubmit. It is important that it takes place during submit, but it seems to always return true and allow the form to post even when it should not. I have tried putting the AJAX portion in its own function and having it return true or false to the validation function but also does not seem to work. Here is what the code looks like... Code: $("#companyform").submit(function() {
$.ajaxSetup({ cache: false });
$.post("ajax_v2Functions.cfm", { coNum: $("#companyNumber").val() },
function(response) {
if(response != "") {
alert("That company number is already in use by " + response);
$("#companyNumber").focus();
return false;
}
return false;
} , "html");
if($("#companyname").val() == "") {
alert("The company name cannot be left blank.");
$("#companyname").focus();
return false;
}
if($("#companyNumber").val() == "") {
alert("The company number cannot be left blank.");
$("#companyNumber").focus();
return false;

I'm make a ajax call to a processing PHP file that echos either "success" or an "error message". When the success is returning, i want Jquery to recognize this and then redirect the browsers instead of displaying the success message. Here are some snippets. I can only seem to parse to a blank or null. Jquery code: Code: $.ajax({
type: "POST",
url: "process.php",
data: wfLoginPost(),
success: function(msg){
alert(msg);
// both below are either null or blank
//var res = $(msg).find("span.response").text();
//var res = $(msg).find("span.response").html();
if(res == 'Success'){
window.location = 'http://www.google.com';
}
}
});
process.php PHP Code: if($qry[0]['pwd'] == $password){ echo "<span class='response'>Success</span>"; }else{ echo "<span class='response'>Username or password did not match</span>"; } Here is the contents of the msg response from the ajax post: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<span class='response'>Success</span>
All, I currently have this code to make a post to my database: Code: var $dataString = 'name='+ $name + '&black_white=' + $black_white + '&color=' + $color + '&color=' + $other + '&other_text=' + $text;
$.post("save_edits.php", {image_save_string: $dataString}, function(result) {
$("#multiple_images").hide();
$("#result_success").html("<font color='red'>We've successfully saved your photo edits!</font><br><br>");
$("#image_divs").html(result);
});
Within the result I'm actually recreating the form for them to use if they want. I have a decent amount of jQuery that got initialized when the original page was loaded. Once I get my new form it doesn't work because it wasn't originally included in the page initialization. Is there a way just to call the document.ready function again to have it reinitialize my form elements again? Thanks in advance. I have a problem where the page doesn't expand when more results get loaded via jquery on a facebook style wall. Once more results get loaded the footer stays static instead of moving down. What's the best way to do this? Hi all, I am using the following script posted on this site: http://www.javascriptkit.com/script/...oundlink.shtml It works great, but I want to extend this script and mute the sound using a checkbox. This checkbox has the id: sound. If checked, I want to hear the sounds, when unchecked, no sounds should be heard. This is the code I currently have for the checkbox: Code: function playSound() {
if (document.getElementById('sound').checked){
-something needs to be added here to make it work?-
}
}
Anyone have an idea how to make this work? Many thanks Hi, I was just wondering is it possible to have an onclick() JavaScript function that would use PHP to INSERT a new row into a MySQL table? Like is it possible to put some php into a javascript function that runs when I click the button on my page? Something like that? The PHP updates the MySQL database and the JavaScript tells the PHP when to happen? Just wondering what's the best way to go about that. |
