javascript - jQuery AJAX callback does not set variable before function returns? -

i have function:

var foo=function(){ var ret="false"; var data={}; data["blah"]="blah"; $.ajax({ type: "post", url: "https://website.com/a", data: data, datatype: "json" }).success(function (data) { ret=data["stuff"]; alert("set "+ret); }).error(function (a, b, c) { alert("error"); ret="false"; }); homecoming ret; }

when following: alert(foo());

i follow order of output:

1.false

2.set true

i expecting ret set true , returning false, not what's happening. doing wrong?

the $.ajax async default. basicly return ret; before javascript set ajax response.

try utilize async: false in $.ajax phone call options.

javascript jquery

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
