Javascript RegEx - Start and End of String Anomalies -



Javascript RegEx - Start and End of String Anomalies -

so im trying basic regex out first time , i've been told theres few ways of stating start , end of string.

one way '\a' & '\z' , other '^' & '$'.

for reason when running in js, later alternative works.

does know why might please?

var str = "123456", pattern1 = new regexp("^\\d{6}$"), pattern2 = new regexp("\a\\d{6}\z"); if(pattern1.test(str)){ alert('pattern 1 match!'); }else{ alert('pattern 1 no match!'); } if(pattern2.test(str)){ alert('pattern 2 match!'); }else{ alert('pattern 2 no match!'); }

i think whoever told \a , \z supposed work misinformed. based on javascript regular expressions documentation, ^ , $ should work.
