Вопрос
How do I use the execCommand() in Chrome? Here is the code I have right now It is being used to insert a special character when hitting the tab button
function editAble(supr){
document.getElementById('codeline').contentEditable='true';
document.getElementById('codeline').onkeydown=function(e)
{
if(e.keyCode==9){
e.preventDefault();
range1 = document.getElementById('codeline');
range1.execCommand("InsertHtml",false,"p");
}
}
}

The execCommand()
method is a method of Document
objects, not elements. IE also provides execCommand()
as a method of its TextRange
and ControlRange
objects, but these are not present in other browsers.
document.execCommand("InsertHtml", false, "p");
You may want to consider what happens if the user presses the Tab key when the user has previously selected some text: in that case you'd probably want to delete the contents of the selection before inserting your tab character.
