问题描述
我的数组没有被正确排序。有人可以让我知道我做错了?
My array isn't being sorted properly. Can someone let me know what I am doing wrong?
...
sortArray = new Array ("hello", "Link to Google", "zFile", "aFile");
//sort array
if (dir == "asc") {
sortArray.sort(function(a,b){return a - b});
} else {
sortArray.sort(function(a,b){return b - a});
}
for(var i=0; i<sortArray.length; i++) {
console.log(sortArray[i]);
}
的日志显示他们以相同的顺序,因为它们被输入。
the log is showing them in the same order as they were entered.
推荐答案
您想在您的排序比较,而不是减法:
You want to make a comparison in your sort, not a subtraction:
if (dir == "asc") {
sortArray.sort(function(a, b) {
return a.toLowerCase() > b.toLowerCase()
});
} else {
sortArray.sort(function(a, b) {
return b.toLowerCase() > a.toLowerCase()
});
}
我也用与toLowerCase()
让链接到谷歌被适当放置。
I also used toLowerCase()
so that 'Link to Google' is placed appropriately.
