Question

How can remove the 'tp.','ta.' and 'tta.' from below string from each place where it is coming

str = " tp.FirstName, tp.FamilyName, ta.DOB, tta.TypeOfLocation
WHERE

tp.DateStamp BETWEEN '2012-02-12 15:13:00' AND '2013-02-12 15:13:00'

AND tta.db_name_id =21
AND

tp.FirstName = 'Darlene'";

I need result as below:

FirstName, FamilyName, DOB, TypeOfLocation
WHERE

DateStamp BETWEEN '2012-02-12 15:13:00' AND '2013-02-12 15:13:00'

AND db_name_id =21
AND

Can try this:

str.replace(/(tp\.)|(ta\.)|(tta\.)/g, '');

Fiddle : check the console

This won't work as . will match any character. Your output will have DateSp BETWEEN instead of DateStamp BETWEEN.

    "aaa tp.bbb tf.ccc  tq.ddddd".replace(/[(tp\.)(tf\.)(tq\.)]/g, "")

    "aaa bbb ccc  ddddd"

But. Regular expressions can be an order of magnitude slower than 'normal' string operations. There are up to 10 browsers and 5 platforms these days where this has to be tested. Hard to believe but this example might be much faster:

     "aaa tp.bbbb  tf.ccc".split("tp.").join("").split("tf.").join("")
     "aaa bbbb  ccc"

Try and test. I would test on very large strings on mobile browsers first. It all depends WHERE do you perceive the primary usage is going to be.

Use this:

str = str.replace(/tp\./g,"").replace(/tta\./g,"").replace(/ta\./g,"");

Try str.substring(str.indexOf(".")) for each word in the string.

var newstring = str.replace(".tp","").replace(".ta","").replace("tta.","");

that would work

Replace (when used with strings) only replaces the first occurrence.
