[Solved] how can I custom a button to insert a html code?

Hi yjfeng ,

I used the other one:http://modxcms.com/forums/index.php/topic,31097.msg188847.html#msg188847

just tested it...inserting <!--splitter--> works with both methods

why I have modified the content of template,but when I select a template from droplist,the code inserted is older one.
for example,in test.htm, I replace code "aaa" with "bbb",but the content inserted is still "bbb"?
I have tried logoff back-end, and re-open brower,but nothing changed.
thank sharkbait again!

I found wheather comment code can be insert depand on browser!

in FF:<!--splitter--> can be inserted well.
in Chorme:<!--splitter--> can’t be inserted. but <!--splitter-->&nbsp; can be inserted.
in IE7,8:<!--splitter--> can’t be inserted,and can’t be refresh by template!

I hate IE!!
