<h1>Option: execcommand_callback</h1>
</div>
<div class="content">
<p>
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.

<h3>Example of usage of the execcommand_callback option:</h3>
<div class="example">
<pre>
function <strong>myCustomExecCommandHandler</strong>(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({
...
<strong>execcommand_callback : "myCustomExecCommandHandler"</strong>
});
