--------------------
Does it occur to anyone else that the way to do this is to work with
the
mouseup event in the textarea itself always updating a hidden field to
the current selection.
-------------------
Interesting that you put it like that since that is what I thought I
was doing. Except that I was using a global var instead of a hidden
field. But the idea was the same, to store the info somewhere
onmouseup(), so as to avoid problems with loss of focus. That is how
the script works. The problem is that my function doesn't seem to be
capturing the info. Just to go over it again, my textarea gets declared
like this:
<div class="formInpu t"><textarea id="inputId5"
name="formInput s[cbMainContent]" style="height:2 00px; width:100%;"
class="textarea Input"
onmouseup="setF ieldSelectionVa lue(this)"></textarea>
<p><a href="#inputId5 " onclick="makeBi gger(inputId5); ">Make box
larger?</a></p></div>
and then setFieldSelecti onValue was trying to capture that value like
this:
// 01-24-05 - most of the time, with most browsers, you can't get a
selection from a form
// input with a function triggered with a form control like a
button, because clicking the
// button shifts the focus to the button and destroys the selection.
So I'm thinking that
// perhaps we can have a global variable that is set with
setFieldSelecti onValue() which
// can be called onMouseUp(). This sets the value and
insertAtCursor( ) can check to see
// if that value is there.
var fieldValue = "";
function setFieldSelecti onValue(myField ) {
// 01-24-05 - this next line is meant to ensure that we don't
// carry an old value forward.
fieldValue = "";
if (document.selec tion) {
if (document.selec tion.createRang e) {
var range = document.select ion.createRange ();
var fieldText = range.text;
} else if (document.selec tion.getRangeAt ) {
// 01-24-05 - this next bit may work in Mozilla
var range = document.select ion.getRangeAt( 0);
if (range) {
if (range.text) {
var fieldText = range.text;
} else if (range.value) {
var fieldText = range.value;
}
}
} else if (document.selec tion.toString) {
var fieldText = document.select ion.toString();
}
} else if ('number' == typeof myField.selecti onStart) {
// MOZILLA/NETSCAPE support
//
myField.value.s ubstring(myFiel d.selectionStar t,myField.selec tionEnd)
var startPos = myField.selecti onStart;
var endPos = myField.selecti onEnd;
if (myField.value. substring) {
if (endPos != 0) {
var fieldText = myField.value.s ubstring(startP os, endPos);
}
}
}
if (fieldText != "") fieldValue = fieldText;
}
