parameters are passed in, you need to obtain the parent node of the first parameter to use the inserbefore function. If (ELEM = Null ) {ELEM=Before;Before=Parent;Parent=Before. parentnode;} Parent. insertbefore (checkelem (ELEM), before );} ; ELEM ELEM. constructor = string ...... Here, the operation order is ELEM (ELEM. constructor = string )...... In addition, inserting data directly from innerhtml is more efficient, but XML does not support the innerhtml attribute.
