[英]Javascript sorting caption array the same way as according data array
我在javascript中有一個排序問題,我需要對數組進行排序並以相同的順序(降序)對字幕(保存在另一個數組中)進行排序,我該如何以相同的方式對其進行排序?
為了清楚起見,我將其簡化為一個基本示例:
var arr = Array(9, 5, 11, 2, 3);
var arrCaptions = Array("some text","another bit of text","three", "four?", "maybe five?");
現在,我想運行一種排序機制,以與arr數組相同的方式對arrCaptions數組進行排序,因此您將獲得以下結果:
var arrResult = Array(11, 9, 5, 3, 2);
var arrCaptionsResult = Array("three", "some text" ,"another bit of text", "maybe five?", "four?");
到目前為止,我嘗試過的一切根本不起作用:
var numlist = Array(9, 5, 11, 2, 3);
var list = Array("four?","maybe five?","another bit of text","some text","three");
var resultnumlist = Array();
var resultlist = Array();
resultnumlist[0] = numlist[0];
resultlist[0] = list[0];
for (i = 0; i < list.length; i++) {
var i2 = list.length - 1;
while (numlist[i] < resultnumlist[i2]) {
i2--;
}
resultnumlist.splice(i2 - 1,0,numlist[i]);
resultlist.splice(i2 - 1,0,list[i]);
}
將它們捆綁在一個對象中。
var stuff = [{
id: 9,
text: "text hello"
}, {
id: 5,
text: "text world"
}, {
id: 11,
text: "text test"
}, {
id: 2,
text: "text 23"
}];
stuff.sort( function( a, b ) {
return a.id - b.id; //Objects are sorted ascending, by id.
});
結果是:
[{
"id": 2,
"text": "text 23"
}, {
"id": 5,
"text": "text world"
}, {
"id": 9,
"text": "text hello"
}, {
"id": 11,
"text": "text test"
}]
如何將它們組合成一個數組? 然后,您可以根據數字的值對該數組進行排序,並且標題將一前一后地排序:
//Your arrays
var arr = [9, 5, 11, 2, 3];
var arrCaptions = ["some text", "another bit of text", "three", "four?", "maybe five?"];
//The composite array
var composite = arr.map(function(v, i) {
return {
rank: v,
caption: arrCaptions[i]
};
});
//Sort this array
composite.sort(function(a, b) {
return a.rank - b.rank;
});
console.log(composite);
這是一個演示: http : //jsfiddle.net/cFDww/
這是修改后的代碼:
var numlist = Array(9, 5, 11, 2, 3);
var list = Array("nine?","maybe five?","another bit of 11","some 2","three");
var resultnumlist = new Array();
var resultlist = new Array();
for (i = 0; i < list.length; i++) {
var i2 = resultnumlist.length - 1;
while ((numlist[i] < resultnumlist[i2]) && (i2 >= 0)) {
i2--;
}
i2++;
resultnumlist.splice(i2, 0, numlist[i]);
resultlist.splice(i2, 0, list[i]);
}
console.log(resultlist);
console.log(resultnumlist);
