as shown in the figure: I use str.replace (/ (null) /, "jsonCallBack");
can only replace the first null,
, but what should I do to replace the third?
the following is the string
"< input type=" radio "name=" p_date_type_sl_sl_sl "value=" id_id_id_D "onclick=" ig.smartSubmit ("ccbppt_form:id_id_id_D",null,null,"ccbppt_form:id_id_id_D,ccbppt_form:parasGrid,ccbppt_form:jsCodes",null); "> < label for=" p_date_type_sl_sl_sl "> Japan < / label >"
then let the rule match only to the third null
replace(/null(?=\);)/,'jsonCallBack')
