Within the webbrowser , is it possible to make a <DIV> element focus?
I am using a WebBrowser object to render text which is presented in a table format. This WebBrowser is embedded within an Eclipse plugin project. In order to comply the accessibility requirement, I need to make each entry in the WebBrower to have focus when using the up / down arrow keys to navigate through the entries so the screen reader can read out the text.
I can detect the up/down arrow keys through the java code, but I don't see the focus to be set on the entry. document.getElementById("+newPos+").focus();
I think this is because only button / form / text field can have focus within HTML.
Is there a way for the element to have focus? Or is there a way for the WebBrowser object to spell out the associated text in the entry when the up / down arrow keys are p开发者_JAVA技巧ressed?
Thanks a lot.
I had problems setting a focus on a div without having a height associated with it, although I did not put any listeners on it to check.
document.getElementById(newPos).focus();
However, without altering the newPos code to that, it errored.
With heights set, and using that alteration it allowed me to switch focus between two divs.
<body onload="var test = 'test2'; document.getElementById(test).focus()">
<div id="test">

Change test from 'test2' to test to see the difference. In the second example it focuses, and I can keypress and it will move up and down. I think it's something to do with the scrolling that causes it.
Hope that is of some help.
