I know how to create help text with a mouseover event.
However, this doesn't work when using a smart phone.
Is there a way to create a button that, when clicked, will display help text that looks the same as the mouseover help text?
hover doesn't exist on mobile devices, and I'm guessing you're meaning while the user touches the Element. If this is the case, I see you have two options:
1 (CSS) Use :active
Example:
Element:active{ /* Stuff to do */ }
2 (Javascript) Use ontouchstart
Element.ontouchstart = function(e)
{
//hovering
};
or
Element.addEventListener('touchstart', function(e)
{
//Hovering!
});
I'll leave you to the rest, because as you said: I know how to create help text with a mouseover event.

I basically want to hide the tooltip on click anywhere in the chart. For this I have configured tooltip as follows:
tooltip:{
hideDelay: 50000 //So that the tooltip stays open for a long time
}
You can check out the example at:
http://jsfiddle.net/e56KT/16/
Anyone with bright ideas!!!
Updated Question:
Before hiding the tooltip:
After hiding the tooltip:
As you can see the div element si not hiding even after hiding the tooltip by the method you described. In a series chart, if we customize the tooltip with increased width and height, the mouse over on other markers doesn't work as this div element stays on top of those markers.
Your code is actually working. It appears not to though because the hide method honors the hideDelay. If you want it to hide immediately try:
hideTooltip = function(){
chart.tooltip.label.fadeOut();
chart.tooltip.isHidden = true;
}
This is what the hide method does internally.
Finally, if you want it to hide if you click anywhere on the chart then I'd hook both the chart: events: click event and the plotOptions: events: click event.

I am a newbie to javascript programming, but am making progress! I am developing a web app in house for children with autism, for touch screen browsers (55" touch screen PCs and Nexus 7 tablets). We will only use Firefox as it appears most compatible. The children will click on image "buttons" to make choices and to communicate their needs. The buttons need to give visual feedback when touched. I have solved this by using the active state in CSS:
img { opacity:1.0 };
img:active { opacity:0.4 };
This works fine. Hover is no good for use on touch screens. I also have a need for some images to be made invisible but to remain where they are, and to toggle on and off on a long press. For this I have found a toggle function and a timer function and combined them.
JAVASCRIPT (in <head> of page):
var t
function tog_vis(id) {
var e = document.getElementById(id);
if(e.style.opacity == 1 )
e.style.opacity = 0 ;
else
e.style.opacity = 1 ;
HTML:
<img id="myimg" onclick="DoSomething();" onmousedown="t=setTimeout(function(){ tog_vis('myimg'); }, 1500);" onmouseup="clearTimeout(t);" src="images/img1.png">
Problem is the active state gets taken over by the onmousedown and onmouseup events (I have read that this is because they are both part of the click event - makes sense!), and I am guessing that the onclick event may also mess things up further.
Expected/Desired behaviour:
1.On a normal click, the image changes opacity to 0.4, and when released returns to 1, then completes the onclick request.
2.On a long click, the image opacity goes to 0, and on a second long click the opacity returns to 1, with NO onclick event.
The app will eventually have # 100 similar images that must perform the first behaviour, whilst the second behaviour will only be needed on # 10 buttons so I could happily code functions individually if necessary. I have also found that the 55" touchscreens (Windows 7) are not responding to the img:active CSS, so guessing these are relying on the touchdown and touchup events, whilst the tablets are very well behaved.
Any help here much appreciated.

You could you css3 transitions and a little javascript for this use case. Have a look at this fiddle: http://jsfiddle.net/Ce8J5/
Also you could realise the hover with javascript/jquery, just remove the hover css statement and define some addionatial css classes and add them via javascript.
E.g.
$("#element").mouseenter(function(){
$(this).addClass(".hover");
});
$("#element").mouseleave(function(){
$(this).removeClass(".hover");
});
I'm trying to work around a webview issue on Android devices using Select drop down menus, using instead radio buttons in a popup to make user selections
What I need though is for the button text to change according to the selection the user has made. I've put togetaher a Fiddle of what I thought would work, but it's not playing ball, and I was wondering if any wiser heads out there could offer some advice.
Fiddle here;
http://jsfiddle.net/vinomarky/gEXhD/
Note: I've currently added some alerts in there when the javascripts fire, but they are not firing, and am not sure why not.
Question 1:
How to change the button text to match the user selection
Question 2:
How to make the radio selection minimize as soon as a user has made a selection, without having to click off the radio
Thanks in advance
you can use jquery click event instead of using onclick attribute
because you use jquery mobile ui, to change button text you should change button text container value not pressure_cands itself
and to hide popup screen when an item selected call click event of popupBasic-screen div
$('#updown1').click(function(){
// to change button label
$('#pressure_cands .ui-btn-text').html('THP');
// call popupBasic-screen click event to hide popup menu
$('#popupBasic-screen').click();
});
$('#updown2').click(function(){
// to change button label
$('#pressure_cands .ui-btn-text').html('FBHP');
// call popupBasic-screen click event to hide popup menu
$('#popupBasic-screen').click();
});
I know how to toggle an entire div, however I only want to hide all but the top 10% or top 100px, for example. And then when the div is clicked, the entire div opens.
I thought I saw this a while ago, but can't remember where.
Thanks.
$(document).ready(function() {
// hides the slickbox as soon as the DOM is ready
$('#slickbox').hide();
// toggles the slickbox on clicking the noted link
$('#slick-toggle').click(function() {
$('#slickbox').toggle(400);
return false;
});
});
Your code should be something in the lines of:
$(document).ready(function() {
// hides the slickbox as soon as the DOM is ready
$('#slickbox').animate({height: '20px'});
// toggles the slickbox on clicking the noted link
$('#slick-toggle').click(function() {
$('#slickbox').animate({height: '100%'});
return false;
});
});
Take a look the image on my home page, is this kind of what you want to do?
http://www.carsonshold.com/
I have it jet out when you hover over it, but that can easily be changed to a click. It somewhat complicated to do, and still isn't perfect in IE (the page loads and the clip isn't recognized until you hover over it).
It may be slightly different from what you want since I did this on an image rather than a div, so I needed to animate the clipping mask. The function I used is as follows:
var featureDuration = 300; //time in miliseconds
$('#featured-img').hover(function() {
$(this).animate({ left : "-164", clip: "rect(0px,384px,292px,0px)" },{queue:false,duration:featureDuration});
}, function() {
$(this).animate({ left : "17px", clip: "rect(0px,203px,292px,0px)" },{queue:false,duration:featureDuration});
});
If you want to animate the clip, you will need to insert this JS as well because it doesn't behave properly otherwise. http://www.overset.com/2008/08/07/jquery-css-clip-animation-plugin/
Take a look at the CSS in my code if you are unsure how I did the rest of it, or comment on here if you have any questions.
Cheers
Did this rather quickly, note it will only hide the bottom portion.

Simple toggle that changes the height, hiding the rest of the content within. Easy enough to animate as well, just modify the toggle functions to adjust the heights rather than adding a class.
I created a contentEditable div to use as a rich textarea. It has resize handlers around it that I'd like to get rid of. Any idea how I'd do this?
Edit: This appears to be happening because I am absolutely positioning the div, so Firefox adds an infuriating _moz_resize attribute to the element which I cannot turn off.
Just as a side note, you can disable Firefox's automatic resize handle feature by sending the (somewhat poorly-documented) enableObjectResizing command to the document:
document.execCommand("enableObjectResizing", false, false);
AFAIK, this can only safely be done once the document has loaded, and there's no way I know of to disable the grabber, which is a separate feature.
It looks like I'll be able to work around this by adding a wrapper div and absolutely positioning the wrapper and then making the inner div contentEditable.
In Chrome 39, these handles don't seem to exist, even if you wanted them to.
In Firefox, one can simply use execCommand, like ZoogieZork answered.
But in Internet Explorer this can't be turned off. It must be worked around.
In WYMeditor development, here's what I've found.
The following results in:
In IE, the resize UI shows up for a split second and then disappears. There seems to be no way for the user to use it.
Images are text selected on mouseup
Ability to drag images. In some browsers, they may have to be selected before dragging. As written in the previous item, a simple mouseup will result in an image being selected.
Images are selected using text selection and not "control selection" (that which provides the resize UI).
This is the best I could come up with after hours of very deep breaths. I think it is good enough if you really want to get rid of those handles.
In IE, Setting oncontrolselect to return false on the image, really does prevent those handles from appearing, and you can do it cleverly, by attaching the following handler to the mousedown event:
function (evt) {
var img;
function returnFalse() {
return false;
}
if (evt.tagName.toLowerCase() === "img") {
img = evt.target;
img.oncontrolselect = returnFalse;
}
}
It actually doesn't work completely well. The reason that it didn't work very well is that in order to begin a drag and drop operation on the image, one had to press and hold the mouse, without moving it, for a split second, and only then begin moving it for the drag. If one pressed the mouse and immediately began dragging, the image would remain in its place and not be dragged.
So I didn't do that.
What I did is the following. In all browsers, I used mouseup to text select the target image exclusively. In non-IE and IE11, synchronously:
function (evt) {
if (evt.target.tagName.toLowerCase() === "img") {
selectSingleNode(img); // In my case, I used Rangy
}
}
In IE 7 through 10, asynchronously:
function (evt) {
if (evt.target.tagName.toLowerCase() !== "img") {
return;
}
window.setTimeout(function () {
selectSingleNode(img); // In my case, I used Rangy
}, 0);
}
This made sure that after those handles show up, they disappear ASAP, because the image loses its "control selection" because that selection is replaced with a regular text selection.
In Internet Explorer 7 through 11, I attached a handler to dragend that removes all selection:
function (evt) {
if (evt.target.tagName.toLowerCase() === "img") {
deselect(); // I use Rangy for this, as well
}
}
This makes the handles that show up after drag and drop, disappear.
I hope this helps and I hope you can make it even better.
I just face that problem.
I tried document.execCommand("enableObjectResizing", false, false); but, the move icon was still appearing. What just fix my problem was just e.preventDefault() when onmousedown event occurs.
element.onmousedown = function(e){
e.preventDefault();
}
for IE11 (I havn't tested the older versions of IE, but I feel like it would work) you can add contenteditable="false" attribute to the img tag. This will prevent any re-sizing from being done while keeping drag and drop in place.
... just the best fix ever
<div contenteditable="true">
<label contenteditable="false"><input/></label>
</div>
or any html element that wraps your input/img
Works on IE11 like a charm
Have you tried adding the style
border: none;
to the div?
