[jQuery] Adding element to an array of object

[FrenchiINLA]

I would like to add a key value to an object array. let's say i have 2
arrays:
            var parArr = new Array('par1', 'par2', 'par3', 'par4');
            var valArr = new Array('val1', 'val2', 'val3', 'val4');

I would like to obtain
ext={par1:val1, par2:val2,pa3:val3,par4:val4}

Any help would be greatly appreciated.
