[jQuery] Re: Removing item from array based on property

[Karl Swedberg]

Hey Mervyn,

this should do it:
var arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}];
for (var i=0; i < arr.length; i++) {
  if (arr[i].a1 == 1) {
      arr.splice(i,1);
    }
}

just loop through the members of the array and check each one's a1  
property. If it equals 1, remove it from the array with the .splice()  
method.

Hello all,

I have a question about removing an item from an array.

I am looking to remove an item from the array based on the property.

Ie.
arr = [{a1: 1, a2: 2},{a1: 3, a2: 4}, {a1: 5, a2: 6}]

remove first item from array because a1 = 1.

I am not entirely sure how to do this. I tried messing around with
grep a bit, but that didn't turn out well.

Thanks
