Hi, I was trying this but it doesn't work with some combinations ... so I came up with this variation: (I multiply the major version by 1000 to cater for having minor versions that go beyond 9 )

function minVersion(version) {
		//console.log('minVersion:: testing for jquery minimum of ' + version );
		if(typeof window.jQuery == 'undefined'){
			console.log('minVersion:: no jquery found ...');
			return false;
		}
		var vrs = window.jQuery.fn.jquery.split('.'),
		min  = version.split('.');
		//pad the arrays to 3 digits
		while(vrs.length < 3)
			vrs.push(0);
		
		while(min.length < 3)
			min.push(0);
		//build a number
		var req = parseInt(min[0])*1000 + parseInt(min[1])*10 + parseInt(min[2]);
		var ins = parseInt(vrs[0])*1000 + parseInt(vrs[1])*10 + parseInt(vrs[2]);
		
		
		return ins >= req;
	}
