How to disable the enter key for a particular component

[ashwaja]

Hi,

On a page I have various components( a lot of button and links). Now, for a specific text field on this page, when the focus is on it, and when the user hits the enter key from the keyboard, the page gets refreshed/submitted.

To handle this, we have used <rich:hotkey> tag to disable the enter key for that text field.

[code]

<rich:hotKey key="return" handler="return false;" />

[/code]

This did help us out, but there are other side effects for this, all the buttons on this page does not react for the enter key from the key board,though the rich:hotkey tag was specified only for that text field.

We would like to disable the enter key only for a specific component and retain the enter key event for other components. Please help me on how to achieve this.

Thanks,

Harish.

There are two ways to register <rich:hotKey>:

• place it anywhere on the page. In this case the <rich:hotKey> component is attached to the whole page (html[0] element). This is default scenario.
• attach it with "selector" attribute to all the elements defined using this selector. This attribute uses defined by w3c consortium syntax for CSS rule selector with some jQuery extensions.

Just define a Selector for the Components you want the hotKey attach to.

Hi,

Thanks Mark for providing your ideas but, we have solved it using a javascript function.

This JS function will check for the keycode of enter key when the key is pressed for any specific field.

Thus we will not handle the event when the enter key is pressed.

Thanks,

Harish.

I'm having the same problem, Harish. Can you paste the code that solved it?

Thanks.

This below code had solved my issue.

function handleEnter(field, event) {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
if (keyCode == 13) { 
  return false;
}
else{
  return true;
}
}

thanks, I solved the problem using the rich: HotKey with selector property like Mark Paluch said.
