首先，您应该查看函数 string.localCompare [

first of all you should look at the function string.localCompare[^] as well as to make it work properly you will have to compare string length too

hiii，

hiii,

function myFunction()
{
var x="abc123";
var y="abc122"
if((x.localeCompare(y)<0 && x.length<=y.length))
{
alert(y);
}
else
{
alert(x);
}
}

希望它能正常工作

hope this will work fine
