javascript - setTimeout doesn't run synchronously -


i'm trying make function show messages after 2 seconds in 'for' function, seems isn't running in order @ all, if set 1 time higher, not wait until done , next task. how make settimeout wait finish before starting new one?

time += 2000; (function(set, cname, time) {     if (cname == "a" || cname == "b") {         settimeout(function() {            text.innerhtml = "somethibng <br />"+text.innerhtml;            set.setattribute("class", "type"+cname );                 }, time);             } else {         settimeout(function() {             text.innerhtml = "something else <br />"+text.innerhtml;                 set.setattribute("class", "type"+cname );                                        }, time);          settimeout(function() { text.innerhtml = "and text <br />"+text.innerhtml; }, time);                 }    })(set, cname, time);

it's async callback, call next settimeout within callback of first.

time += 2000; (function(set, cname, time) {     if (cname == "a" || cname == "b") {         settimeout(function() {             text.innerhtml = "somethibng <br />"+text.innerhtml;             set.setattribute("class", "type"+cname );                 }, time);             } else {     settimeout(function() {         text.innerhtml = "something else <br />"+text.innerhtml;             set.setattribute("class", "type"+cname );                                     /******* call second settimeout once first 1 finished ***/         settimeout(function() { text.innerhtml = "and text <br />"+text.innerhtml;      }bind(<pass things second timeout if need>),    time);           /**** notice bind, it's not mandatory (unless pass vars second timeer) **/          }), time);               }       })(set, cname, time);
