I want to replace selected text(or insert new text after cursor position if nothing is selected).
The new text is entered from another textbox.
I want to be able to insert new text without clicking first (focusing) in the textarea.
meaning: first
select text to replace inside textarea, then enter new text into the textbox and click the button.
<textarea id='text' cols="40" rows="20">
</textarea>
<div id="opt">
<input id="input" type="text" size="35">
<input type="button" onclick='pasteIntoInput(document.getElementById("input").value)' value="button"/>
</div>
function pasteIntoInput(text) {
el=document.getElementById("text");
el.focus();
if (typeof el.selectionStart == "number"&& typeof el.selectionEnd == "number") {
var val = el.value;
var selStart = el.selectionStart;
el.value = val.slice(0, selStart) + text + val.slice(el.selectionEnd);
el.selectionEnd = el.selectionStart = selStart + text.length;
}
else if (typeof document.selection != "undefined") {
var textRange = document.selection.createRange();
textRange.text = text;
textRange.collapse(false);
textRange.select();
}
}
Online example:
link text
