This option allows you to add a custom callback function for execCommand handling. This enables you to override internal command functions in TinyMCE. The example below shows how the mceLink and mceImage are overriden.
Example of usage of the execcommand_callback option:
function myCustomExecCommandHandler(editor_id, elm, command, user_interface, value) {
var linkElm, imageElm, inst;
switch (command) {
case "mceLink":
inst = tinyMCE.getInstanceById(editor_id);
linkElm = tinyMCE.getParentElement(inst.selection.getFocusElement(), "a");
if (linkElm)
alert("Link dialog has been overriden. Found link href: " + tinyMCE.getAttrib(linkElm, "href"));
else
alert("Link dialog has been overriden.");
return true;
case "mceImage":
inst = tinyMCE.getInstanceById(editor_id);
imageElm = tinyMCE.getParentElement(inst.selection.getFocusElement(), "img");
if (imageElm)
alert("Image dialog has been overriden. Found image src: " + tinyMCE.getAttrib(imageElm, "src"));
else
alert("Image dialog has been overriden.");
return true;
}
return false; // Pass to next handler in chain
}
tinyMCE.init({
...
execcommand_callback : "myCustomExecCommandHandler"
});
