Opera input type="checkbox" Problem

try the the following code with Opera 9.01 (Windows). when clicked
slightly faster than normal clicking, the toggler checkbox and other
checkboxes displays differently although event method works fine to
update the checkboxes. there is not any problem with IE 6 or FireFox
1.5. also, i used the double click event method to see if its the
source but that does not help even. Opera 9.01 seems to be slow at
updating checkboxes visually. am i missing something or are there any
work arounds, solutions for this problem.

Yeah, I noticed that too with the Opera 9.x series. :-(

BTW, Opera 8.54 doesn't seem to have this problem.

As such, for the time being, the work-arounds seem to be either:

a) Swap-out your onclick event with either onmousedown or onmouseup
b) Click slowly
c) Revert back to 8.54
d) Use an alternate browser.

Cheers.

I have a large form that is generated dynamically in a jsp using xml / xslt. So, to break up this form into several "tabbed" sections, I break up the form using <div> tags. Each <div style="display:none"> can be displayed by setting the style attribute to "display:", or hidden with "display:none". This gives the illusion that the person filling out the form is switching from page to page...without the overhead of extra hits on the server,...

I want to know what's wrong with this code (I'm an amateur programmer). I'm trying to check if every field has a value or if checkboxes/radios have at least one item checked on each group (yes, you know, with the same name in the HTML tag). I want to have a generic code which I can fit to every document. The problem is that it never got into the line: if(elm.type == "checkbox" || elm.type == "radio") I've put an alert(elm.type)

Hi, Does the following indeed imply that this event is NOT called when an <input type="checkbox" is toggled? This would thus imply the usage of the onClick handler instead (assuming an action needs to be invoked on check/ uncheck). W3C Recomendation: 18 Scripts onselect = script The onselect event occurs when a user selects some text in a text field. This attribute may be used with the INPUT

Hi all, I was trying to make an image submit button with a rollover and discovered to my suprise that there is no way to access a form element of the "image" type. I tried specifying it by name and also by the elements array with no luck. Even weirder, I can sandwich an image button in between other input types and then write a script diplaying the contents of the elements array and it acts as if the image button does not exist at all!...

I noticed that using an HTMLInputRadioButton and specifying a value to be an empty string (""), this is overridden by ASP.Net which set the value of the control to be the same as the ID of the control.

Hi all.. I have a DataGrid with checkboxes. In the header I have a "check all" checkbox. I'm wondering if there is an easy way to check all checkboxes using that checkbox. I could do it using JavaScript code, but the main problem I have is that checkboxes ids aren't kept when the datagrid is rendered, for example, if the checkboxes have the name chkNumid, when the datagrid is rendered, the checkboxes become dgDataGrid_ctl02_chkNumId,

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
