Re: get a a char's position when its string is clicked

Is it possible to get the cursor's position in an input text?

Try this function (IE only):

function caretPos(){
var i=document.f.txt.value.length+1;
if (document.f.txt.createTextRange){
theCaret = document.selection.createRange().duplicate();
while (theCaret.parentElement()==document.f.txt &&
theCaret.move("character",1)==1) --i;
}
return i==document.f.txt.value.length+1?-1:i;
}

You 're lucky you have an input. I use this function in a textarea, and if
my cursor is at the 345th position, it takes quite a while for the while
loop on line 5 to reach the end.

Works great with Ie. Didn't know about the createTextRange,
parentElement stuff

Thank you very much !
