app 版本比较代码

function compareVersion(Version) {
var arr = [];
var result=”;
arr = Version.split(“.”);
if (arr.length == 3) {
arr.push(0)
}
var sum = 0;
arr[0] = arr[0] * 1000;

arr[2] = arr[2] * 10;
for (var i = 0; i < arr.length; i++) {
sum += parseInt(arr[i]);
}
//与2.6.6比较
result=sum >= 2660 ?’big’ :”small”;
return result;
}
alert(compareVersion(‘1.1.0.3’))
