javascript - Joining ajax results? -

-

I will have to produce a result from 2 XMLHttpRequests how I can make requests concurrently and wait for both ends Can i do

I have something like this ... 

  resp1 = ""; Req1.onreadystatechange = function (if {this.readyState = 4) resp1 == this.responseText;} req2.onreadystatechangefunction () {if (this.readyState = 4) Finish (this.responseText);} Function Finish (resp2 ) {If (resp1 == "") setTimeOut (end (resp2), 200); Other {... both are done ...}

I have not tested it yet but I think it will work. Is there a better way? My code should be as quick and fast as possible.

You do not need a timer for this.

You only have to check in one callback whether the other has ended or not, and if so, then call ended .

For example: 

  var resp1 = null, resp2 = null; Req1.onreadystatechange = function () {if (this.readyState === 4) {resp1 = this.responseText; If (resp2! == faucet) ends (); }}; Req2.onreadystatechange = function () {if (this.readyState === 4) {resp2 = this.responseText; If (resp1! == faucet) ends (); }};

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
