I just wanted to ask if onmouseup and onmousedown events are supported on touch screen mobile devices when deployed.
I have this code here:
<img src="images/plus.png" id="+" onclick=compare(this.id) onmousedown=changeplus() onmouseup=changeplus2() class=plus_button style="width:100px; height:100px;">
And I'm not sure if the device will support those.
I can't test it because I don't have the device yet.
If it is not, is there any alternative for that?
Thanks in advance.
You can simulate Touch events, in Chrome browser easily.
1- Press F12 to see Developer Tools
2- Click on the 'Settings' icon in bottom-right corner
3- Go to 'Override' section in Settings Panel
4- Activate check-box: 'Emulate Touch Events'
That's all! Ready to test your code.

i have 7 button gaming mouse when i press back button on mouse this media dialog appear , when i scroll anywhere on any tab this is also appear . please tell me how can i disable this one its very irritative .
i already disable hardware media key hendling and Global Media Controls Modern UI from chrome://flags/
This was finally resolved.
Near the scrolling wheel is a dpi button, which also can be used to switch
between normal and media mode by holding it for 3 seconds. In the media mode the wheel controls the volume and does not scroll.
I need to right click on an element and go to inspect element.
I have tried to right click but since its a touch device emulator that action doesn't make sense, the dropdown doesn't appear.
It works fine when i am not in the emulator mode checking for things, but when i am in the emulator for touch devices (ipad, iphone, galaxy), I lose the right click.
How do it make chrome open that html tag just like the inspect element, so i don't have to dig through the html trying to find the element i want?
thanks in advance! :)
Left click and hold on the element in the emulation window.
The context menu will then appear, and you'll need to move your mouse to Inspect Element before releasing the click to activate it.
You can use either the magnifying glass in the top left corner of the developer tools, or you could turn off the touch sensor emulation by going to Emulation|Sensors|Emulate touch screen and turn it back on after you find your element.
Since the last update of Google Chrome, a screen ruler shows up when inspecting an element. Does anyone know how to disable this ruler?
This is an old question, but now you can enable or disable now in Chrome Developer Tools -> Settings -> Show Rulers (you can also access the settings just pressing F1).
In Chrome 38, there is a "Toggle Device Mode" button to the left of menu items in developer tools. Clicking on it will toggle display of ruler and device emulation list.
Go to "Settings" -> "General" tab.
In the end of page, click on button "Restore defaults and reload".
=)
It's not possible for the moment.
You need to wait Chrome 25 or use Canari.

This is now known as Device Mode. It allows you to select different device screen sizes as well as emulate different Network Speeds.
You can enable/disable it by clicking the Phone Icon on your console.
Upgrading to the latest dev release fixed this for me:
http://www.google.com/chrome/intl/en/eula_dev.html?dl=mac
This started happening to me out of the blue. I use Chrome inspect element for developing, on a personal computer that no one else uses.
This morning, I had the whole rulers-and-menus thing appear as if out of nowhere.
The above suggestions did nothing. When I got to the configuration check-box for rulers, I discovered it was turned off.
I was able to get the old look back by resetting the defaults in the same config menu which held the rulers check-box. Hope that helps anyone stuck like I was.
When you have the unspect editor opened, Just go to settings by clicking the icon (top right on the unspector) there you will find a big button saying restore defaults and reload . That worked for me . Good luck
I'm using Chrome Canary (Version 45.0.2451.0 canary), and the presence of the rulers appears to be tied to whether Emulation is enabled. Restoring defaults (as suggested above) turns it off, or you can just go to the drawer at the bottom and do it.
I'm building out my jquery mobile app out and have been testing in Chrome. Its the best for me because the debugging is great.
I was using a TAPHOLD event but decided to go away from that for a swipe-right event.
Chrome actually registered the taphold, so I was hopeful that it would register a swipe right with the mouse. But I cannot get it to register unless I have to do something else... anyone?
By now the actual chrome developer tools (tried chrome 20) can emulate touch and swipe events.
You can activate that behavior through the tool options, accessible via the little gear-wheel in the bottom corner.
Just check "Emulate touch events" from the options. Then you can also swipe with your mouse.
In desktop browsers I tend to use the right mouse button testing swipes. It will open a context-menu but it actually works (I normally use Chrome 17 and Firefox 10).
For instance when left-clicking and then swiping on an image in Chrome or Firefox it selects the image and you are then moving around the transparent thumbnail of the image. But when right-clicking and swiping the swipe event is fired.
UPDATE
This update is pretty late to the punch but this just shouldn't be necessary anymore. In fact the Chrome developer tools (the ones I'm used to using) have gotten a lot better about emulating devices.
A lot of the answers here are old and out of date. As of Chrome 63, swipe is built-in as long as you are in responsive mode with developer tools open. So open Developer Tools (3 dots->tools->developer tools), then click the phone/tablet icon on the left to put Chrome into a mobile mode. Then if you left click and hold, you will see the cursor changed to a dot, and you can swipe.
Update: this appears to be enabled in Chrome by default (37.0.2062.120 as of September 2014) you do the following:
Open Developer Tools
Click the little phone icon next to the search icon in the upper left (next to the Elements tab)
In the Emulation tab on the bottom choose a device model from the drop down
Previous answer:
To get this working in the current version of Chrome (32.0.1700.107 as of Feb 2014) you do the following:
Open Developer Tools
Click the gear icon in the upper right
Select the Overrides tab on the left
Click on Show 'Emulation' view in console drawer
Close the Settings popup
Open the Console (button to the left of the gear)
Click the Emulation tab in the console (next to Console and Search)
Choose a device and click on Emulate (and click Reset to cancel emulation)
I'm trying to get up to speed on HTML5 by prototyping an extremely simple drawing app using <canvas> and touch events like ontouchstart and ontouchmove.
This is displaying and working fine in an Android emulator where I use mouse clicks to simulate touch events. However, it doesn't work at all when running in my desktop browser (Safari 5.1.1, Firefox 7 on Windows).
I thought the mouse click events would be interpreted as touch events like they are when running within the emulator.
I wonder now if perhaps desktop browsers simply don't support touch events.
It's actually the other way round. Mobile browsers translate touch to mouse events for legacy support. If it needs to work on both mobile and desktop, and you don't really need touch events, you could just use mouse events instead. Failing that, bind both touch and mouse events and have the touch event cancel the mouse event. This way on mobile devices the touch fires and mouse doesn't. On desktop the touch doesn't fire and the mouse will.
For pilau, here's a simple example of cancelling the click event on mobile devices. Please note the question is more about drawing which would involve click dragging, which would require a bit more code for detection, but the basic idea is the same, bind the events you need to handle. Then e.preventdefault() will stop the mobile browsers from emulating click type events.
$('#element').on('touchend click', function(e){
// Do your onclick action now
// cancel the onclick firing
e.preventDefault();
});
Firefox 6 and above supports the touch events. See the compatibility table here.
MDN article on Touch Events
EDIT : Are you testing with a touchscreen or the mouse? The mouse events do not automatically translate to touch events. See this post for how to simulate touch events with a mouse.
ontouchstart will be a add on to the iphones version of webkit for javascript. you could test it but only on an emulator.
If you are working with react, the synthetic events are different:
onClick Works for both, mobile and desktop.
onTouchStart works only for mobile. Also, this event goes before the onClick event. Maybe it is the first event to being trigged.
In my case, I needed an event before the onClick event in a mobile and desktop environment, so I used onMouseDown. which with synthetic events from React, works for both, mobile and desktop.
Remember, for development propose, the easiest way to test in mobile or in desktop is with the developer tools, clicking on Toggle device toolbar or cmd + shift + M in the inspector.
Good luck!
