javascript 在数组元素中搜索

Question

我有这样的数组:

var notes = ["user1,date:13/2/2008,note:blablabla", "user1,date:15/2/2008,note:blablabla", "user1,date:17/2/2008,note:blablabla", "user1,date:13/3/2008,note:blablabla"];

我有

var search_date="17/2/2008";

我想找到最后一次出现的笔记和该笔记的用户。任何人都知道如何？预先感谢您的回复。

Answer 1

试试这个:

var highestIndex = 0;
for (var i = 0; i < notes.length; i++){
    if (notes[i].indexOf(search_date) != -1){
        highestIndex = i;
    }
}
//after for loop, highestIndex contains the last index containing the search date.

然后获取用户，可以这样解析:

var user = notes[highestIndex].substring(0, notes[highestIndex].indexOf(',') - 1);
