Question

I have a textbox and a link button. When I write some text, select some of it and then click the link button, the selected text from textbox must be show with a message box.

How can I do it?

---

When I click the submit button for the textbox below, the message box must show Lorem ipsum. Because "Lorem ipsum" is selected in the area.

If I select any text from the page and click the submit button it is working, but if I write a text to textbox and make it, it’s not. Because when I click to another space, the selection of textbox is canceled.

Now problem is that, when I select text from textbox and click any other control or space, the text, which is selected, must still be selected.

How is it to be done?

OK, here is the code I have:

function ShowSelection() {   var textComponent = document.getElementById('Editor');   var selectedText;    if (textComponent.selectionStart !== undefined)   { // Standards-compliant version     var startPos = textComponent.selectionStart;     var endPos = textComponent.selectionEnd;     selectedText = textComponent.value.substring(startPos, endPos);   }   else if (document.selection !== undefined)   { // Internet Explorer version     textComponent.focus();     var sel = document.selection.createRange();     selectedText = sel.text;   }    alert("You selected: " + selectedText); } 

The problem is, although the code I give for Internet Explorer is given on a lot of sites, I cannot make it work on my copy of Internet Explorer 6 on my current system. Perhaps it will work for you, and that’s why I give it.

The trick you look for is probably the .focus() call to give the focus back to the textarea, so the selection is reactivated.

I got the right result (the selection content) with the onKeyDown event:

document.onkeydown = function (e) { ShowSelection(); } 

So the code is correct. Again, the issue is to get the selection on click on a button… I continue to search.

I didn’t have any success with a button drawn with a li tag, because when we click on it, Internet Explorer deselects the previous selection. The above code works with a simple input button, though…
