javascript - checking for an array in an multidimensional array (pref-jQuery) -

i've got multi-dimensional array, , i'm trying check if holds array. i'm using jquery.inarray function @ moment (i trying array.prototype kept getting errors, never used before).

i trying ensure parent array doesn't add same child array twice

 if(jquery.inarray(new array(step[0],step[1],r2),unavailarray)==-1){     alert(jquery.inarray(new array(step[0],step[1],r2),unavailarray));      unavailarray.push(new array(step[0],step[1],r2));   }  

i've tried

 jquery.inarray("[step[0],step[1],r2]",unavailarray)==-1 

and

 jquery.inarray([step[0],step[1],r2],unavailarray)==-1 

they return -1, , when @ array, have

 [[630,690,09],[3180,3220,2],[3180,3220,2]] 

so isn't working.

i believe you're issue keep adding new array() arrays instead of giving them variable name point to, hence they're never same though may have same exact content each other.

for work wish need assign new array([step[0],step[1],r2]) variable , check variable instead of new array()

var blah = new array(step[0],step[1],r2);  // add array unavailarray if(jquery.inarray(blah,unavailarray)==-1){     alert(jquery.inarray(blah,unavailarray));      unavailarray.push(blah);   }else{     alert('found not added'); }  // try again , wont, instead firing off alert message if(jquery.inarray(blah,unavailarray)==-1){     alert(jquery.inarray(blah,unavailarray));      unavailarray.push(blah);   }else{     alert('found not added'); }
