JavaScript - Jquery Ui - Limiting Move Axis.
Hi all, using the Draggable featu http://jqueryui.com/demos/draggable/
How can I limit the draggable div so it hits the sides of the container? It states I can do this: Quote: Constrains dragging to either the horizontal (x) or vertical (y) axis. Possible values: 'x', 'y'. Code examples Initialize a draggable with the axis option specified. $( ".selector" ).draggable({ axis: 'x' }); Get or set the axis option, after init. //getter var axis = $( ".selector" ).draggable( "option", "axis" ); //setter $( ".selector" ).draggable( "option", "axis", 'x' ); But I don't really understand it. :S Not great with Javascript - so please make it simple! Thanks. Similar Tutorialswhat is the best way to count the seconds between each onkeyup to "autosave" without sending an ajax command after each key? id like my script to update after 2 seconds of no typing.... (yes, jquery is in use on the page) Code: function microtime (get_as_float) {
var now = new Date().getTime() / 1000;
var s = parseInt(now, 10);
return (get_as_float) ? now : (Math.round((now - s) * 1000) / 1000) + ' ' + s;
}
var lastKeyUp=0;
function saveChange(id,field,value){
thismicrotime=microtime(true);
if(lastKeyUp == 0 || (thismicrotime-lastKeyUp) >= 2000000){
$.get("saveChange.php",
{ 'field': field, 'value': value, 'id': id },
function(data){
lastKeyUp=thismicrotime;
},
'xml'
);
}
}
Code: <input type="text" name="field1" onkeyup="saveChange('2','field1',this.value);" />
i'd use onchange or onblur but that requires you to unfocus the field before it saves... I'm programming a function that breaks a massive string (2 million + characters) into "manageable" chunks of 500,000 characters. The function goes as follows: Code: var json_string = "{'action':'message-send','recipients':recipients,'message':message";
var bytes_chunks = scripting.messages.voice.recorder.bytes.chunk(500000);
$.each(bytes_chunks,function(i,v){
json_string += ",'voice_bytes_"+i+"':'"+v+"'";
});
json_string += "}";
As you can see, everything should work fine, and the function should return a stringified json array (which would be parsed and sent to a server) but the string is truncated and function exited after the first interval. When I decrease the length of "v" using substr to 5 characters, all the expected children are returned. What could the problem be? I have the following javascript code: Code: elms=document.getElementById('friends').getElementsByTagName('li');
for(var fid in elms){
if(typeof elms[fid] === 'object'){
fs.click(elms[fid]);}
}
Which grabs all "li" tags with the ID "friends" , and then goes through and clicks all of those elements. How would I go about having it to where it only clicks up to 200 elements, and not all of them. Hi I am wondering how I would limit the drop zones to just one image per drop zone? Code: <ul id="images"> <li><a id="1" draggable="true"><img src="images/1.jpg" value = "flower"></a></li> <li><a id="2" draggable="true"><img src="images/2.jpg" value = "boy"></a></li> <li><a id="3" draggable="true"><img src="images/3.jpg" value = "girl"></a></li> </ul> <form name = "objects" id="form" action = "form.php" method = "post"> <div class="drop_zones"> <div class="drop_zone" id="drop_zone1" droppable="true" type = "text" name = "drop_zone1"> </div> <div class="drop_zone" id="drop_zone2" droppable="true" type = "text" name = "drop_zone2"> </div> <div class="drop_zone" id="drop_zone3" droppable="true" type = "text" type = "file" name = "drop_zone3"> </div> </div> Code: var addEvent = (function () {
if (document.addEventListener) {
return function (el, type, fn) {
if (el && el.nodeName || el === window) {
el.addEventListener(type, fn, false);
} else if (el && el.length) {
for (var i = 0; i < el.length; i++) {
addEvent(el[i], type, fn);
}
}
};
} else {
return function (el, type, fn) {
if (el && el.nodeName || el === window) {
el.attachEvent('on' + type, function () { return fn.call(el, window.event); });
} else if (el && el.length) {
for (var i = 0; i < el.length; i++) {
addEvent(el[i], type, fn);
}
}
};
}
})();
var dragItems;
updateDataTransfer();
var dropAreas = document.querySelectorAll('[droppable=true]');
function cancel(e) {
if (e.preventDefault) {
e.preventDefault();
}
return false;
}
function updateDataTransfer() {
dragItems = document.querySelectorAll('[draggable=true]');
for (var i = 0; i < dragItems.length; i++) {
addEvent(dragItems[i], 'dragstart', function (event) {
event.dataTransfer.setData('obj_id', this.id);
return false;
});
}
}
addEvent(dropAreas, 'dragover', function (event) {
if (event.preventDefault) event.preventDefault();
this.style.borderColor = "#000";
return false;
});
addEvent(dropAreas, 'dragleave', function (event) {
if (event.preventDefault) event.preventDefault();
this.style.borderColor = "#ccc";
return false;
});
addEvent(dropAreas, 'dragenter', cancel);
// drop event handler
addEvent(dropAreas, 'drop', function (event) {
if (event.preventDefault) event.preventDefault();
// get dropped object
var iObj = event.dataTransfer.getData('obj_id');
var oldObj = document.getElementById(iObj);
// get its image src
var oldSrc = oldObj.childNodes[0].src;
oldObj.className += 'hidden';
var oldThis = this;
setTimeout(function() {
oldObj.parentNode.removeChild(oldObj); // remove object from DOM
// add similar object in another place
oldThis.innerHTML += '<a id="'+iObj+'" draggable="true"><img src="'+oldSrc+'" /> </a>';
// and update event handlers
updateDataTransfer();
// little customization
oldThis.style.borderColor = "#ccc";
}, 500);
return false;
});
Anyone know? Dear Forum Members HI, I am no coder, however I am modifying my website and changing the slideshow to the one found on this website, most wonderful, the Cut & Paste JavaScript Slideshow( http://www.javascriptkit.com/script/.../jsslide.shtml ) I have it working now, and I have but one question, does the code include a way to limit the number of times that it cycles through the slides? So it just freezes on one photo after x number of cycles? many thanks, and happy holidays... I want to limit the number of characters shown in a select box when its 'dormant' ie. I want the drop down to have the full word but when something is selected, I want it to show only the first 3 characters of the word. I can limit the width to a fixed px width but the right width is different depending on the word. (its a drop down of month names, I want them to have the full 'grown up' name in the drop down but that's too long and cumbersome for the space I have, I've trimmed it down by setting the width in CSS but it looks so much neater when the first 3 characters just show in the box rather than 4 or 3.5) In my previous post, I asked how to create a function that would allow me to add to or subtract from a maxvalue, and thankfully I got help regarding that. However, something's got me stumped for the past few weeks that I still can't resolve... This is the relevant code: Code: <html>
<head>
<script type="text/javascript" language="Javascript">
function chgAdv(btn)
{
var form = btn.form;
var newqty = parseInt(btn.value);
var maxqty = form.maxqty;
var maxadv = form.maxadv;
if (eval("btn.checked") == true && parseInt(maxadv.value) + newqty <= 15) {
var newmax = parseInt(maxqty.value) - newqty;
var newadv = parseInt(maxadv.value) + newqty;
}
else if (eval("btn.checked") == false && parseInt(maxadv.value) - newqty >= 0) {
var newmax = parseInt(maxqty.value) + newqty;
var newadv = parseInt(maxadv.value) - newqty;
}
else {
var newmax = parseInt(maxqty.value);
var newadv = parseInt(maxadv.value);
}
if ( newadv >= 0 && newmax >= 0) {
maxqty.value = newmax;
maxadv.value = newadv;
}
}
function chgDis(btn) {
var form = btn.form;
var newqty = parseInt(btn.value);
var maxqty = form.maxqty;
var maxdis = form.maxdis;
if (eval("btn.checked") == true && parseInt(maxdis.value) + newqty <= 10) {
var newmax = parseInt(maxqty.value) + newqty;
var newdis = parseInt(maxdis.value) + newqty;
}
else if (eval("btn.checked") == false && parseInt(maxdis.value) - newqty >= 0) {
var newmax = parseInt(maxqty.value) - newqty;
var newdis = parseInt(maxdis.value) - newqty;
}
else {
var newmax = parseInt(maxqty.value);
var newdis = parseInt(maxdis.value);
}
if (newdis >= 0 && newmax >= 0) {
maxqty.value = newmax;
maxdis.value = newdis;
}
}
</script>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<form name="f1">
<b>Advantages</b> (<input type="text" class="RO" name="maxadv" value="0" />)<br />
<input type="checkbox" class="RO" name="Absolute Direction" onclick="chgAdv(this);" value="2" />Absolute Direction<br />
<input type="checkbox" class="RO" name="Allies" onclick="chgAdv(this);" value="3" />Allies<br />
<hr>
<b>Disadvantages</b> (<input type="text" class="RO" name="maxdis" value="0" />)<br />
<input type="checkbox" class="RO" name="Antisocial" onclick="chgDis(this);" value="2" />Antisocial<br />
<input type="checkbox" class="RO" name="Ascetic" onclick="chgDis(this);" value="4" />Ascetic<br />
max quantity: <input type="text" readonly class="RO" name="maxqty" value="40" />
</form>
</body>
</html>
styles.css is simply: Code: input.RO {
border: none;
width: 40px;
text-align: center;
}
As it stands, it works as long as the total value is less than or equal to the limit (for advantages it's 15, for disadvantages it's 10). However, the moment it goes past the limit -- for instance, if you change Antisocial's value from 2 to 7, or if you add several additional checkboxes with any values -- the whole thing starts going crazy; specifically, maxvalue doesn't revert to 40 when the all the checkboxes are unchecked. What I'd want to happen is that the user cannot select or apply advantages or disadvantages if the maximum advantage is greater than 15 or the maximum disadvantages is greater than 10. I'm thinking that a button for adding disadvantage points to/subtracting advantage points from the maxvalue (that becomes disabled if the user goes past his limit on advantages/disadvantages) is useful at this point, but I'm really stumped on the implementation of the idea. An alternate idea of mine is that all other advantage/disadvantage checkboxes would become disabled if their value is greater than the remaining number of points, but I don't know how that is possible either. Any and all help is greatly appreciated. So, i have this code which retrieves php files for me using jquery and id love to get it working with Jquery history plugin. I tried modifying the code i got from the ajax demo to work for me, but i just couldnt do it as i do not know any javascript really.. ( actually what i tried was simply to change "#ajax-links a" to "#menu li a" and .html to .php ..but nothing.. :rolleyes: Id be very gratefull if someone would help me out with this one. All related code can be found bellow (the ones that should be needed anyways): This is the code that retrieves php files inside "#content" when item from "#menu li a" with the specified id is clicked Code: $(document).ready(function(){
//References
var change = $("#menu li a");
var loading = $("#loading");
var content = $("#content");
//Manage click events
change.click(function(){
//show the loading bar
showLoading();
//load selected section
if(this.id == "home")
{
change.load(this.className='current-page');
content.slideUp();
content.load("pages/index.php", hideLoading);
content.slideDown();
}
else if(this.id == "secondpage")
{
change.load(this.className='current-page');
content.slideUp();
content.load("pages/secondpage.php", hideLoading);
content.slideDown();
}
else
{
//hide loading bar if there is no selected section
hideLoading();
}
});
//show loading bar
function showLoading(){
loading
.css({visibility:"visible"})
.css({opacity:"1"})
.css({display:"block"})
;
}
//hide loading bar
function hideLoading(){
loading.fadeTo(1000, 0);
};
});
Heres the structure of the menu/content Code: <ul id="menu"> <li><a id="home" class="normal" href="#Home"></a></li> <li><a id="secondpage" class="normal" href="#Secondpage"></a></li> </ul> <div id="content"> <ul id="sec-menu"> <li><a id="link1" class="normal" href="#">Link1</a></li> <li><a id="link2" class="normal" href="#">Link2</a></li> </ul> </div> Heres the code that jquery history plugin uses in demo for ajax Code: jQuery(document).ready(function($) {
function load(num) {
$('#content').load(num +".html");
}
$.history.init(function(url) {
load(url == "" ? "1" : url);
});
$('#ajax-links a').live('click', function(e) {
var url = $(this).attr('href');
url = url.replace(/^.*#/, '');
$.history.load(url);
return false;
});
});

Hey all im getting used to using .js still and I am trying to figure out how to create a button to move a selected field within a box of fields to the top, instead of just moving it one-by-one to the top. Here is what I currently have that moves the selected just up one. Can someone expand on this and make it so it will move to the top instead of just one? SearchFieldsWindow.prototype.cmdMoveUp_OnClick = function() { var searchFields = this.__searchFields; var items = this.__lstSelected.get_Items(); var selectedIndices = this.__lstSelected.get_SelectedIndices(); var count = selectedIndices.get_Count(); for (var i = 0; i < count; i++) { var selectedIndex = selectedIndices.get_Item(i); // Don't allow when first item selected if (selectedIndex == 0) break; var uniqueID = items.get_ItemValue(selectedIndex); var label = items.get_ItemLabel(selectedIndex); searchFields.MoveUp(uniqueID); items.RemoveAt(selectedIndex); items.Insert(selectedIndex - 1, uniqueID, label); this.__lstSelected.SetSelected(selectedIndex - 1, true); this.__lstSelected.SetSelected(selectedIndex, false); } }; So if the user enters a serial number in the "Serial_Number" field and hits enter I would like the cursor to move DOWN to the next "Serial_Number" field. Is this possible?? Tracy Code: <table>
<tr>
<td>
Serial Number:<br>
<input
type = "text"
size = "30"
onclick = "this.select();"
onChange = "updateField(this.name,this.id,this.value)";

Hello. Could you guys point me in the right direction. I have a DIV that I woul like to move along with the users vertical scrollbar. So when the user scrolls down on the page the DIV will follow. Where can I find information on how I can do this.
I have a form with two text input boxes. I want to limit the text typed into the boxes as follows: 1. Either box can have the number 2 typed in, but the other box must remain empty OR 2. Each box can have the number 1 typed into Is this possible with JS and, if so, how do I do it?? Hi Guys. First off i'd like to say Hi as i'm new to the forums. But am looking forward to spending a lot of time here. I am currently studying Javascript to help create a bit more user interaction with my websites which I use CSS/XHTML and PHP5 to design. Ok with that said I was hoping someone might be able to lend a slight hand. I am trying to create an Image menu for a site I'm working on that is rather simple in essence. When the user hovers over a button I have the menu will move left or right depending. I have not got a great deal into it yet as I have become stuck, as I'm new I figured it would be easier to troubleshoot if I build up the program bit by bit. ----> menupic variable is being passed by php into javascript Code: function moveImagesLeft() {
for (i=0; i<=100; i++) {
setPixels = (i + 2);
for (L=1; L<=menuPic; L++){ /* this loop makes sure that all the pictures move together */
indexpic = "menupic"+L;
document.getElementById(indexpic).style.left="-"+setPixels+"px";
}
}
}
Ok, very simple. I have a DIV container that holds my images and the overflow is hidden, php works out how many images there are and feeds that into javascript. This all works fantastically however it seems that once I reach the bottom of my second for loop Code: document.getElementById(indexpic).style.left="-"+setPixels+"px"; Nothing else happens, the pictures all shift left 2pixels as they should but nothing else. The top loop is not going again (excuse the poor use of terminology) I dont know if it makes a different but where the images are they are declared as so. Code: <a href="#"><img class="menupic" id="menupic1,2,3,4,5 (etc)" src="_image" border="0" height="50" width="60"></a> Code: .menupic {position:relative; display:block; width:60px, height:40px}
and the Id class is there so that my javascript can control it. I hope that I have worded this in a way that is easily understandable. Any help would be greatly appreciated. I try not to ask for too much help because working things out is part of the learning curve but in this instance I have spent a lot of time and not found a solution. Kindest Regards Oli Right. I'm trying to create a little game (If you can call it that) where every time the user hovers over a <div> which contains a button, said <div> moves to a random point on the page. I've tried a way of moving the item and Googled extensively but have not yet come up with a way of doing it. This is my current code: Code: if(document.getElementById)
{
var carrier = document.getElementById(btnarea);
carrier.style.top = randomHeight + "px";
}
if(document.getElementById)
{
var carrier = document.getElementById(btnarea);
carrier.style.left = randomWidth + "px";
}
Which does not work. I hover over the <div> and the button, yet nothing happens. I can click the button, which seems to be the only thing working right now. I have a feeling the issue could be with another part of the code, but I wanted to see what you people thought first. Any ideas? You can see it working (Or not) at http://zeroerror.co.uk/public/clickme.php. Thanks in advance. Hi once again! Is it possible to detect was the mouse on the move or not in the moment when button is released ? Hi all, I'm trying to do something with a WYSIWYG editor. Below is a piece of code that takes selected text and wraps various BBCodes around it. The code almost works... but I want a few changes and I hope someone has an idea for me. Note: the var range = ed.selection.getRng(true); line gets a W3C compatible range containing the current selection - even under MSIE. The editor takes care of this. Note: The var elem = ed.dom.create('span', false, ' '); line creates a SPAN element with the initial content " " and returns it's element in "elem". Code: var ed = (tinymce.activeEditor || opener.tinymce.activeEditor);
if(ed)
{
var sel = ed.selection.getContent();
var range = ed.selection.getRng(true);
var elem = ed.dom.create('span', false, ' ');
elem.innerHTML = bbopen + sel + bbclose;
range.deleteContents();
range.insertNode(elem);
ed.selection.select(elem);
ed.focus();
return;
}
This code works, but not exactly as I want. For example, if I type "This is a test" and wrap code tags around it, I get this: But what I WANT is this: Also, if I select no text and hit the BBCode button, I get the open tag and the close tag, all highlighted. What I want in this case is the open tag, the close tag and the cursor IN BETWEEN them ready for text insertion. I'm thinking that I can take the range start and end offsets and move them to get what I want, but so far I've failed. One thing I DON'T want to have to do is create THREE spans... one for the open, one for the selection and one for the close. Trying to avoid that if possible. Any help will be greatly appreciated! Thanks! -- Roger |
