jQuery   testID2   find   test2   replaceWith   test3      Semantically  you are selecting the element with the ID testID2  then you are looking for any descendent elements with the class test2  does not exist  and then you are replacing that element with another element  elements anywhere in the page with the class test3  that also do not exist   You need to do this   jQuery   testID2   addClass  test3   removeClass  test2      This selects the element with the ID testID2  then adds the class test3 to it  Last  it removes the class test2 from that element

testID  testID2   removeClass  test2   addClass  test3      Because you have assigned an id to img too  you can simply do this too       testID2   removeClass  test2   addClass  test3      And finally  you can do this too       testID img   removeClass  test2   addClass  test3
