rich text editor - javascript: Google Closure - RichTextEditor plugin -

i making custom plugin rich texteditor sets span class selected text, like: <span class="myclass">text</span>

ok, pretend have following text:

this test. 

now after selecting test , clicking button trigger plugin output:

this <span class="myclass">test</span>. 

now after select whole text , click button again, output:

<span class="myclass">this <span class="myclass">test</span>.</span> 

any idea how fix this?

you use rangy library , class applier module.

var applier = rangy.createcssclassapplier("myclass"); applier.applytoselection();
