JavaScript - Ipad Touchmove Event Problem.
Quick question, I found this code snip on stackoverflow and it has one little bug. When you touch / move in the element, the console.log is being fired. If you continue to drag / move outside the element, the console.logs still continue to fire.
So it seems that once the event is started it's no longer confined to the element its being assigned to. Any ideas on how to keep it bound to the element? Here is the code: Code: $('#someElm').bind('touchmove',function(e){
e.preventDefault();
var touch = e.originalEvent.touches[0] || e.originalEvent.changedTouches[0];
console.log(touch.pageY+' '+touch.pageX);
});
Thanks in advanced. Similar TutorialsHello I'm having problems with a very simple bit of Javascript not working with the latest version of Safari for ipads and iphones. The script in question is used as a 'previous image ' and 'next image' navigation facility, basically closing one pop-up window and opening up another, when viewing a photo gallery. It has worked perfectly for a number of years on all browsers. It is only the latest version of Safari for ipads and iphones where there's a problem. On an iphone, the new window unfortunately opens up in a new tab and the existing window fails to close. Mobile Safari soon reaches the maximum of 8 permissible tabs as a user moves through the photos gallery. On an ipad2, no new window opens and the existing window fails to close. the website is www.gethigh.co.uk Code:
}
function picPopup4(page,width,height){
//alert(scroll);
var a;
a = width / 2;
var b;
b = height / 2;
var LeftPosition = (screen.width/2) - a;
var TopPosition = (screen.height/2) - b;
window.open(page, "", "width="+width+",height="+height+",toolbar=no,header=no,location=no,resizable=yes,"+"left="+LeftPosition +",top="+TopPosition+",scrollbars=yes");
window.close();
}
and this is an example of the code creating the navigation within each pop-up window Code:
<tr>
<td align="center"><a class="link8" href="javascript:picPopup4('legslip1.html','560','770');" target="_self">
previous image</a> <a class="link8" href="javascript:window.close()">close
window</a> <a class="link8" href="javascript:picPopup4('breaking2.html','505','800');" target="_self">next
image</a></td>
</tr>
I'll come clean and admit I'm not a programmer and have a very basic and ancient understanding of HTML coding. My website must be approaching double digit years old (which will be immediately apparent if you view its structure). I can usually resolve most things, and maintain its functioanality when needs be, but this particular problem has got me stumped. I've come onto this forum to see if anyone could provide a simple work-around ? Or if anyone would know if this is a bug within Safari which may be rectified soon (a search through the Apple forums gave no clues). I'm loathed to make any major updates/changes to my site, as despite its age it renders beautifully on all browsers except the latest ipad/iphone Safari.

Hi All, Need a bit of help here, need this SELECT to submit the page and end up at the below URL, correctly passing the GET values through the string. <code> <select name="dir-fact-misma" id="dir-fact-misma" class="text100" tabindex="" onChange="alta_nueva.action='alta.php?page=p2#alta'; return true;"> <option value="Si" <?php if(!isset($_POST['dir-fact-misma']) || $_POST['dir-fact-misma'] == 'Si') print "Selected='Selected '"; ?>>Si</option> <option value="No" <?php if(isset($_POST['dir-fact-misma']) && $_POST['dir-fact-misma'] == 'No') print "Selected='Selected '"; ?>>No</option> </select> </code> the form in which this SELECT is placed needs to be submitted so that other fields in the form are not lost, they are saved in Session Variables. the same javascript but activated through an onclick event works perfect elsewhere in the same form with the following code, i think its the onChange that doesn't work for some reason. <code> <input name="p1" type='submit' id="p1" onclick="alta_nueva.action='alta.php?page=p1#alta'; return true;" value='1' /> </code> the page is programmed in PHP.

i m very new to this thread so i will try to be as clear as possible i m try to create a website where i n have inserted a menu (this menu template i found online which is free.) Code: <div id="menu">
<ul class="menu">
<li><a href="#" class="parent"><span>Home</span></a>
<li><a href="#"><span>Cities</span></a>
<div><ul>
<li><a href="#"><span>Pune</span></a></li>
<li><a href="#"><span>Mumbai</span></a></li>
<li><a href="#"><span>Delhi</span></a></li>
<li><a href="#"><span>Madras</span></a></li>
</ul></div>
</li>
<li><a href="#"><span>Login</span></a></li>
<li><a href="#"><span>About Us</span></a></li>
<li class="last"><a href="#"><span>Contact Us</span></a></li>
</ul>
</div>
what i am trying to do here is when i click on city (one of the menu) it should read the values from database table (the table name is cityCode. this table contains two rows first cityName and second cityCode) n depending on which city is selected it should retrieve the code of that city. also where to save that retried value because i want to use that retried code to extract value from another table. Realizing that form input placeholders aren't universally recognized among browsers, I began changing all of mine using onblur and onfocus handlers instead. As an example, I used the following code, which works in most cases: Code: <input type="text" name="example" maxlength="5" value="Example" onblur="if(this.value=='') this.value='Example';" onfocus="if(this.value=='Example') this.value='';"/> At first, I coded all of the inputs without a value attribute. But, when the page initially loaded, the fields would load empty, and the value/placeholder wouldn't appear until the field had been "focused" and then "blurred" again. Adding the value attribute seemed to correct that problem, again, for the most part. I have some text fields that appear only after I select a particular radio button or select option. Problem is, when the radio is clicked, the field appears, but even with the value attribute in place, the field appears void. I'm not sure what is different, or what I'm doing wrong. Here's the javascript code with the radio button (note:everything works except that the "placeholder" doesn't show when the field first appears): Code: function showfield() {
document.forms[0].otherRelation.value = "";
document.getElementById("newBox").style.display = "none";
var r = document.forms[0].relation;
var len = r.length;
for (var i =0; i<len; i++) {
if (r[i].checked && r[i].value == "Otherrelation" ) {
document.getElementById("newBox").style.display = "inline";
}
}
}
<input type="radio" name="relation" value="Otherrelation" onclick="showfield()"/>Other
<span id = "newBox" style="display:none">:
<input type = "text" name="otherRelation" size="35" value="Your Relationship" onblur="if(this.value=='') this.value='Your Relationship';" onfocus="if(this.value=='Your Relationship') this.value='';"/>
</span>
Thanks for any help. Sorry so long. I'm trying to simulate a textfield on a canvas; that is when clicking on the text box a cursor appears and blink. My problem here is when I create more than one object, the event listener will work only on the last object created. Here is my code: Javascript Code: var canvas;
var ctx;
var MousePosX;
var MousePosY;
var Cursor_Width = 1;
var Cursor_Height = 21;
var Height = 27;
var LapseTime = 800;
function init(CanvasName) {
canvas = document.getElementById(CanvasName);
ctx = canvas.getContext("2d");
}
/*
Create Textfiled
*/
function Textfield(x, y, w) {
Textfield.prototype.x = x;
Textfield.prototype.y = y;
Textfield.prototype.w = w;
Textfield.prototype.Cursor_PosX = x + 3;
Textfield.prototype.Cursor_PosY = y + 3;
// draw rectangle
ctx.beginPath();
ctx.rect(this.x, this.y, this.w, Height);
ctx.closePath();
ctx.stroke();
// listen for mouse click event
canvas.addEventListener("mousedown", function(evt) {
// calculate mouse coordination on canvas
MousePosX = evt.clientX - canvas.offsetLeft;
MousePosY = evt.clientY - canvas.offsetTop;
// if mouse coordination is within texfield display cursor
if((MousePosX > Textfield.prototype.x && MousePosX < (Textfield.prototype.x + Textfield.prototype.w)) && (MousePosY > Textfield.prototype.y && MousePosY < (Textfield.prototype.y + Height))) {
Textfield.prototype.cursor();
}
});
}
/*
Cursor for textfield
*/
Textfield.prototype.cursor = function() {
// alert("good");
ctx.beginPath();
ctx.strokeStyle = "black";
ctx.rect(this.Cursor_PosX, this.Cursor_PosY, Cursor_Width, Cursor_Height);
ctx.closePath();
ctx.stroke();
setTimeout("Textfield.prototype.animate_cursor()", LapseTime);
};
/*
Change color of cursor to white to make blinking effect
*/
Textfield.prototype.animate_cursor = function() {
ctx.strokeStyle = "white";
ctx.stroke();
setTimeout("Textfield.prototype.cursor()", LapseTime);
};

I'm doing this nonprofit site for a students club in my college, and it needs an event calendar. I just have a bit of touch on javascript, and the only way this is going to be done in is javascript so I'm stuck with it. I took one of my assignments and modded it to the requirements of them. 1. A 6 month calendar. problem - I have to get thismonth, check whether its <July,then display Jan to June. Else July to December.(A semester calendar) figured it out. 2.Want to highlight a specific date, and place a link in it, so when somebody click the date, say a textarea in a form, displays the event details. problem - Have no idea on how to do it.

Hello all, I'm wondering if anyone can offer advice on a simple (or so I thought!) Javascript menu I'm trying to create. I'm creating 5 buttons, using event handlers (onmouseover etc) which exchange 1 image for another. I did the first one fine - it worked perfectly, but as soon as I added the rest they all stopped working properly. The best I have got, is that the last link will do what it's supposed to regardless of which link I hover over! Which is strange. So the browser seems to be actioning the last thing on the list if that makes sense. It seems to me that I need to add an "if" type attribute, so "if" I hover over the home button, the home images change, as opposed to the last one on the list. This is the code I have so far for a single link - the rest are copies of this with adjustments made to the imgname and image sources obviously..... <div style="width:80px; height:20px;margin-top:20px;margin-left:85px;"><a href="about.html" onMouseOver="return changeImage()" onMouseOut= "return changeImageBack()" onMouseDown="return handleMDown()" onMouseUp="return handleMUp()" ><img name="aboutbutton" src="img/aboutn.png" width="80" height="20" border="0" alt="javascript button 1"></a> <script language="JavaScript"> upImage = new Image(); upImage.src = "img/abouth.png"; downImage = new Image(); downImage.src = "img/aboutc.png" normalImage = new Image(); normalImage.src = "img/aboutn.png"; function changeImage() { document.images["aboutbutton"].src= upImage.src; return true; } function changeImageBack() { document.images["aboutbutton"].src = normalImage.src; return true; } function handleMDown() { document.images["aboutbutton"].src = downImage.src; return true; } function handleMUp() { changeImage(); return true; } </script></div> Any suggestions on where I am going wrong would be wonderful. Thanks so much in advance! All the best Hello, I have a script I am using which works great, except when I copy the code and have multiple events it only shows the first one. This I believe is because it's calling the first class name of it's kind. I want the class's to be named the same thing (css styling) and because the site is going to be dynamically driven, but is there a way to modify my script so that instead of looking for the first class it recognizes the right class associated with the button clicked. If anyone can help me fix this problem I am having I would be most appreciative.. Code: <script language="javascript">
function toggle() {
var ele = document.getElementById("commpopup");
if(ele.style.display == "block") {
ele.style.display = "none";
}
else {
ele.style.display = "block";
}
}
</script>
<div class="togglecomment">
<div class="popup" id="commpopup">
<div class="commentbtn"><a href="#"><img src="images/commenticon.png" align="absmiddle" />Comment</a></div>
</div>

Hi forum, I am trying to attach an event to a dynamically produced button, and then use stopPropagation and preventDefault. Code: function chapter12_nodeOne() {
//create an element
var element = document.createElement('input');
//set some attributes
element.setAttribute('type', 'button');
element.setAttribute('value', 'submit');
element.setAttribute('id', 'myBtn');
//appendd the element into a DIV
document.getElementById('myDiv').appendChild(element);
//uses EventUtil to attach an event listener
EventUtil.addHandler(element, 'click', function() {
alert('event attached');
});
var flag = confirm('prevent default behavior of button?');
if (flag) {
var el = document.getElementById('myBtn');/////////////////////////(1)
var ev = el.onclick;
}
}
var EventUtil = {
addHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.addEventListener) {
element.addEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.attachEvent) {
element.attachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = handler;
}
},
removeHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.removeEventListener) {
element.removeEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.detachEvent) {
element.detachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = null;
}
}
};
But when debugging I see under el on the line marked with (1) that the onclick event is null. What am I doing wrong?! PS:the event is attached, when I click on the button I get an alert message **just realised I have put this in the wrong section
is it possible to capture the control.event or element.event that was fired to invoke the onbeforeunload event. for example, if a button is clicked and it causes the onbeforeunload event to fire can i determine which button was clicked. thanks I have the following javascript function: [ function addNewWindowEvent(evType, fn) { if (window.addEventListener) { this.addEventListener("load", fn, false); return true; } else if (window.attachEvent) { var onload = "onload" this.attachEvent(onload, fn); return true; } else { return false; } } ] which is giving me a an exception every time a page on our site loads. The actual exception in firefox is this: uncaught exception: [Exception... "Could not convert JavaScript argument" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: https://cms-dev.stchas.edu/global/js/hdvscripts.js :: addNewWindowEvent :: line 5" data: no] and I'm not sure exactly what it's complaining about. I'm relatively new to javascript so diagnosing and fixing this problem has me quite puzzled, and so far I have been unable to find anything helpful when I try and google for information on this. I would appreciate any help or suggestions. Thanks. henryv Ok, so I have multiple issues, but this is the one I have not been able to work around. I'm building a simple website for personal use, so I know it only has to work on Safari for the iPad, a simple catalog of song charts for use on stage in my piano bar. Everything works GREAT in Safari/Chrome for Windows 7, but doesn't seem to quite work on Safari for iPad. The issue I'm having is I've set up a DIV with two image buttons on it to execute a ScrollBy command to scroll the page up or down depending on the button. Everything works great on Safari for Windows 7, as in I can keep scrolling down the page by pressing the scroll down button multiple times. On iPad, it only works once, and will not continue to scroll. I've also tried it in Atomic Lite for iPad, with the same effect. I've mocked up a simple page, to take all the other variables out. http://www.duelingpianopiano.com/jef...testscroll.htm Eventually, I will be installing it he http://www.duelingpianopiano.com/jef...testscroll.htm The code in the head tag is below: <code> <script language="JavaScript" type="text/javascript"> <!-- Copyright 2003, Sandeep Gangadharan --> <!-- For more free scripts go to http://sivamdesign.com/scripts/ --> <!-- var y1 = 510; // change the # on the left to adjuct the Y co-ordinate (document.getElementById) ? dom = true : dom = false; function hideIt() { if (dom) {document.getElementById("layer1").style.visibility='hidden';} } function showIt() { if (dom) {document.getElementById("layer1").style.visibility='visible';} } function placeIt() { if (dom && !document.all) {document.getElementById("layer1").style.top = window.pageYOffset + (window.innerHeight - (window.innerHeight-y1)) + "px";} if (document.all) {document.all["layer1"].style.top = document.documentElement.scrollTop + (document.documentElement.clientHeight - (document.documentElement.clientHeight-y1)) + "px";} window.setTimeout("placeIt()", 10); } // --> </script> <script language="JavaScript"> function scrollup(){ parent.scrollBy(0,-window.innerHeight-50); } function scrolldown(){ parent.scrollBy(0,window.innerHeight-50); } </script> </code> The code from the body tag: <code> <body topmargin="00" leftmargin="0" rightmargin="0" bottommargin="0" marginwidth="0" marginheight="0" link="#FFFFFF" vlink="#FFFFFF" alink="#FFFF00" bgcolor="#FFFFFF" "overflow: visible" onLoad="placeIt(); showIt()"> INSERT CONTENT HERE <div id="layer1" style="position:absolute; right:0; width:50px; height:150px; visibility:hidden"> <font face="verdana, arial, helvetica, sans-serif" size="2"> <div style="float:left; background-color: ; padding:0px; border:0px solid black"> <img src="upbutton.png" width=50 height=75 border="0" align="left" onClick="scrollup();"> <img src="downbutton.png" width=50 height=75 border="0" align="left" onClick="scrolldown();"> </div> </code> Like I said, it works just as needed in Safari/Chrome for Windows 7, but not on iPad. Doesn't seem to work in IE 8, but that doesn't bother me. I have not tested in FireFox. Your ideas are much appreciated. I'm not an Apple person, so maybe there is a well known issue with scrollBy and Safari for iPad, that I'm not aware of. If that is the case, if anyone has an idea for a direction for a workaround that would be great as well. Eventually, I would like to use the smooth scrolling scripts that I've seen out there, but that is way down the road. I'm more worried about the functionality as is. hi all, I want to be able to move an image from a left or right when tilting my ipad. when tilted the the right the image moves to the right according to the angel tilted and do the same to the other direction. the image is doubled (or more) the size of the stage (1024x768). I can't use Flash for obvious reasons so looking at other options. thanks The web page belows works OK in IE and FireFox on XP and Windows7 It does NOT work on IPAD using Safari. Question: How can I delete the new window("IPADREPORT") when I run it the second, third,fourth, etc time ? How can I get the window name( "IPADREPORT") to see if it exists? SUggestions? TIA, Steve42 <code> [aSafari.html] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"> <html lang="en"> <head> <script language="JavaScript" type="text/javascript"> function pReport(){ // 1-17-12 var menuWindow = open("","ipadreport"); // 1-17-12 menuWindow.close(); // above closes previous report window var menuWindow = window.open('','ipadreport');// 1-17-12 document.ipadreport.submit(); menuWindow.focus(); } </script> <title>Ipad_PopUp_Test</title> </head> <body> <br><br> <form method=post name="ireport" target="ipadreport" action="http://myreport.asp"> <input type="hidden" name="reporttest" value="apple"> <a href='javascriptReport()'> Create Report</a> </form> </body> </html> </code> I have a ondrag event handler and in that I am trying to retrieve e.ClientX but it always return 0 in Mozilla. Works fine in IE though. How can retrieve the clientX and clientY in ondrag event? Hi Guys, I've been searching the net for both examples and pluggins to create draggable divs and although I've found many, I cant find the effect I'm after. I want the div to slow down to a stop after it has been release like when you are scrolling on one of apples mobile devices. If anybody can point me in the right direction ill be very great full. |
