textRange object   

Hi,

Surprisingly, no one seems to have encountered this issue anywhere I've 
searched.

My problem is, while looping through a document using the textRange object, 
it appears that when it encounters the search string in text that is not 
"selectable", such as the href value in a link, or other "non-displayed" 
html, I get the following error:

Error: Could not complete the operation due to error 800a025e.

It would have been nice if there was an "isSelectable", or "innerText" 
property on the textRange object.

Any suggestions, solutions or work-a-rounds?

Thanks 

Tony

I'm not sure I understand. In my experience, TextRange only searches the 
displayed text, it does not look inside element attributes. Can you show 
an example of what you are doing?

You mean like textRange.text property?

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly

Re: textRange object   

Igor,

Thank you for your response...It got me to look at the problem differently.

It turns out that the problem was DIVs with the style display set to "none". 
Guess it's kinda hard to select text thats display is being suppressed.

You where right about findText searching the displayed text only. Although, 
when I created the range from the body, ALL HTML was included in the range, 
so I assumed THAT text being searched literally. Somehow findText is smart 
enough to only search the text that the user will actually see. 

Uh, with the exception of "non-displayed" DIVs of course.

Thanks again.

Tony

You could call select() inside try / catch block, this way you can 
intercept any error before it reaches the user.

Another approach is to use boundingHeight and boundingWidth properties. 
I suspect, but am not sure, that they would both be 0 when TextRange is 
positioned over hiddent text.

Yet another is to use parentElement() method, then walk up the 
parentElement chain until you either reach the element with no parent 
(usually the document) or find an element with display:none style.
