Am I wrong??

 

After I read your recommend article , I try to adding script following on the aspx page:

 

I expect when I click [u] toolbar, tag <u> should be removed.

 

But it does not effect anything.

 

<script>

function CuteEditor_FilterHTML(editor,code) {  

return code.replace(/(<u[^\>]*\>)([\s\S]*)(\<\/u\>)/i, "$2");

}

function CuteEditor_FilterCode(editor,code) {  

return code.replace(/(<u[^\>]*\>)([\s\S]*)(\<\/u\>)/i, "$2"); }

</script>
