要素の css を交換してユーザーに表示しようとしています。例:
#box{background-color:#ccc; float:left} // original css
次に、ユーザーは、発言先を変更して、発言bg-color者を に変更します。#008000inline#box
したがって、新しいCSSは次のようになります#box{background-color:#008000; float:left}
以下は、私がこれに使用しているコードです:

私は2つの値を比較することができません.値は完全に保存され、ifステートメントは常に次のように返されfalse
ます.
if(c_prop==prop){
