javascript - Execute a method whenever some method has finished executing completely -

i've javascript method defined follows:

updtcrtedtpage = function() {primefaces.ab({source:'j_id_ev',formid:'j_id_es',process:'typenewlob_in lobidforedit j_id_ev',update:'createlobfullpagepanel',oncomplete:function(xhr,status,args){prepareforcrtedtfullpage();},params:arguments[0]});} 

i want execute method (aftercomplete()) whenever method has finished executing. (this method initiates ajax request & appends received html data on dom). want aftercomplete() method executed whenever ajax response has been received.

i cannot directly like:

updtcrtedtpage(); aftercomplete(); 

as call aftercomplete() after ajax request initiated & not finished executing yet.

is there js/ jquery way ?

you pass aftercomplete parameter function can call when ajax call complete. this...

updtcrtedtpage = function(callback) {     primefaces.ab({         source:'j_id_ev',         formid:'j_id_es',         process:'typenewlob_in lobidforedit j_id_ev',         update:'createlobfullpagepanel',         oncomplete:function(xhr,status,args){             prepareforcrtedtfullpage();             callback();         },         params:arguments[0]     }); }  updtcrtedtpage(aftercomplete); 

since can't modify updtcrtedtpage, can modify prepareforcrtedtfullpage i'd suggest using global variable determine callback function call when method complete...

updtcrtedtpagecallback = aftercomplete; 

and in prepareforcrtedtfullpage add last line...

updtcrtedtpagecallback(); 

the first method tidier, second suffice particular situation.
