sort（）数组顺序与数字 [英] sort() array names sequentially with numbers

问题描述

大家好，不久之后我问如何排序一个字符串数组，这些字符串将会有数字，我希望按顺序数字顺序排列。


例如：


myArray [0] =" file1" ;;

myArray [1] =" ; file2" ;;

myArray [2] =" file3";

myArray [3] =" file4";

myArray [ 4] =" file5";

myArray [5] =" file6";

myArray [6] =" file7";

myArray [7] =" file8";

myArray [8] =" file9";

myArray [9] =" file10";

myArray [10] =" file11";


等...


但是使用普通排序功能下面的数字排序......

----------------------------------- ----

功能比较（a，b）{

返回（ab）

}


myArray.sort（比较）;

------------------------------- --------

按照我不想要的顺序返回数组并且不一致。


例如：

myArray [0] =" file1";

myArray [1] =" file10";

myArray [2] =" file2" ;;

myArray [3] =" file3";

myArray [4] =" file4";

等..


当它达到20等时会发生同样的事情。


我在下面给出了这个代码，它在大多数现代浏览器中都很有用但是

崩溃IE5，实际上它会弹出一个警告，说该脚本已经运行了很长时间并且希望我保释。任何人都可以解释为什么这个

代码失败或知道另一种方法来实现这个目标吗？

函数cmp（a，b）{

返回（b
}

函数numCmp（a，b）{

var re1 = /（\d +）| \ D + / g;

var re2 = /（\d +）| \ D + / g;

re1.lastIndex = 0;

re2.lastIndex = 0;

var res = 0;

do {match1 = re1.exec（a）; match2 = re2.exec（b）;

if（match1）{if（match2）{

if（match1 [1]）{

if （match2 [1]）{

res = Number（match1 [1]） - 数字（match2 [1]）||

cmp（match1 [0]，match2 [0]）;

} else {res = -1;}

} else {if（match2 [1]）{res = 1;

} else {res = cmp（match1 [0]，match2 [0]）;}}

} else {res = 1;}} else {if（match2）{res = - 1;} else {res = 0;休息;

}

}

} while（res == 0）;

返回res;

}

Hi all, A while back I asked how to sort an array of strings which would
have numerals and I wanted to put them in sequential numerical order.

For example:

myArray[0] = "file1";
myArray[1] = "file2";
myArray[2] = "file3";
myArray[3] = "file4";
myArray[4] = "file5";
myArray[5] = "file6";
myArray[6] = "file7";
myArray[7] = "file8";
myArray[8] = "file9";
myArray[9] = "file10";
myArray[10] = "file11";

etc...

However using the normal sort function below for numerical sorting...
---------------------------------------
function compare(a,b){
return(a-b)
}

myArray.sort(compare);
---------------------------------------
returns the array in an order I do not want and is not consistent.

For example:
myArray[0] = "file1";
myArray[1] = "file10";
myArray[2] = "file2";
myArray[3] = "file3";
myArray[4] = "file4";
etc..

Same thing happens when it gets to 20 etc..

I was given this code below which works great in most modern browsers but
crashes IE5, actually it pops an alert that the script has been running a
long time and wants me to bail. Can anyone shed some light as to why this
code fails or know of another way to accomplish this?
function cmp(a,b) {
return (b<a)-(a<b);
}
function numCmp(a,b) {
var re1 = /(\d+)|\D+/g;
var re2 = /(\d+)|\D+/g;
re1.lastIndex = 0;
re2.lastIndex=0;
var res = 0;
do{ match1 = re1.exec(a);match2 = re2.exec(b);
if(match1){if (match2){
if(match1[1]) {
if(match2[1]) {
res = Number(match1[1]) - Number(match2[1]) ||
cmp(match1[0],match2[0]);
}else{res = -1;}
}else{if(match2[1]){res = 1;
}else{res = cmp(match1[0],match2[0]);}}
}else{res = 1;}}else{if(match2){res = -1;}else{res = 0; break;
}
}
} while(res == 0);
return res;
}

myArray [8] =" file9";
myArray [9] =" file10";
myArray [10] =" file11" ;;


然而，使用下面的常规排序函数进行数字排序...



和...为什么不重命名你的电影es？

myArray [0] =" file01";

myArray [1] =" file02";

myArray [2] =" file03";

myArray [3] =" file04";

myArray [4] =" file05";

myArray [5] =" file06";

myArray [6] =" file07";

myArray [7] =" file08" ;;

myArray [8] =" file09";

myArray [9] =" file10" ;;

myArray [10] =" ; file11" ;;


会修复你的myArray.sort（比较）

----------------- ----------------------
功能比较（a，b）{
返回（ab）
}
myArray.sort（比较）;
---------------------------------- -----
按照我不想要的顺序返回数组，并且不一致。

例如：
myArray [0] =" file1" ;;
myArray [1] =" file10" ;;
myArray [2] =" file2";
myArray [3] =" file3";
myArray [4] =" file4";
等。

同样的事情发生在20等...

Hi all, A while back I asked how to sort an array of strings which would

myArray[0] = "file1";
myArray[1] = "file2";

myArray[4] = "file5";
myArray[5] = "file6";
myArray[6] = "file7";
myArray[7] = "file8";
myArray[8] = "file9";
myArray[9] = "file10";
myArray[10] = "file11";

etc...

However using the normal sort function below for numerical sorting...

and ... why not rename your files ?

myArray[0] = "file01";
myArray[1] = "file02";
myArray[2] = "file03";
myArray[3] = "file04";
myArray[4] = "file05";
myArray[5] = "file06";
myArray[6] = "file07";
myArray[7] = "file08";
myArray[8] = "file09";
myArray[9] = "file10";
myArray[10] = "file11";

would fix your myArray.sort(compare)
---------------------------------------
function compare(a,b){
return(a-b)
}

myArray.sort(compare);
---------------------------------------
returns the array in an order I do not want and is not consistent.

For example:
myArray[0] = "file1";
myArray[1] = "file10";
myArray[2] = "file2";
myArray[3] = "file3";
myArray[4] = "file4";
etc..

Same thing happens when it gets to 20 etc..

>并且...为什么不重命名你的文件？

因为他们不会成为我的档案而我无法控制他们的名字

命名，但他们必须按特定顺序排序。

David

> and ... why not rename your files ?
Because they won''t be my files and I will have no control over what they are
named, however they must be sorted in a specific order.
