Ajax响应转换 [英] Ajax response conversion

问题描述

我有这个由ajax返回的数组:

I have this array that is returned by ajax:

console.log(res);
["07Apr|1", "06Apr|3", "05Apr|12", "04Apr|11", "03Apr|0", "02Apr|0", "01Apr|6", "31Mar|0", "30Mar|7", "29Mar|16", "28Mar|5", "27Mar|5", "26Mar|12", "25Mar|9", "24Mar|4", "23Mar|10", "22Mar|16", "21Mar|2", "20Mar|19", "19Mar|22", "18Mar|10", "17Mar|11", "16Mar|10", "15Mar|19", "14Mar|0", "13Mar|4", "12Mar|14", "11Mar|5", "10Mar|26", "09Mar|7", "08Mar|5"] 

我使用JSON.stringify转换此数组:

I convert this array using JSON.stringify:

(变量"res"是我的ajax的响应，如上所示)

(The variable "res" is the response of my ajax -as shown above)

            var obj = [];
            var daysBack = 30;
            var objItem = {};
            for(var x = 0; x <= daysBack; x++){
                var currObj = res[x];
                var objCombo = currObj.split("|");
                var objItem = "{date: '"+objCombo[0]+"', downloads: '"+objCombo[1]+"'}";
                objItem = JSON.stringify(eval("(" + objItem + ")"));
                obj.push(objItem);
            }

将"obj"转储到控制台时，我得到:

When I dump the "obj" to the console I get:

console.log(obj); 
["{"date":"07Apr","downloads":"1"}", "{"date":"06Apr","downloads":"3"}", "{"date":"05Apr","downloads":"12"}", "{"date":"04Apr","downloads":"11"}", "{"date":"03Apr","downloads":"0"}", "{"date":"02Apr","downloads":"0"}", "{"date":"01Apr","downloads":"6"}", "{"date":"31Mar","downloads":"0"}", "{"date":"30Mar","downloads":"7"}", "{"date":"29Mar","downloads":"16"}", "{"date":"28Mar","downloads":"5"}", "{"date":"27Mar","downloads":"5"}", "{"date":"26Mar","downloads":"12"}", "{"date":"25Mar","downloads":"9"}", "{"date":"24Mar","downloads":"4"}", "{"date":"23Mar","downloads":"10"}", "{"date":"22Mar","downloads":"16"}", "{"date":"21Mar","downloads":"2"}", "{"date":"20Mar","downloads":"19"}", "{"date":"19Mar","downloads":"22"}", "{"date":"18Mar","downloads":"10"}", "{"date":"17Mar","downloads":"11"}", "{"date":"16Mar","downloads":"10"}", "{"date":"15Mar","downloads":"19"}", "{"date":"14Mar","downloads":"0"}", "{"date":"13Mar","downloads":"4"}", "{"date":"12Mar","downloads":"14"}", "{"date":"11Mar","downloads":"5"}", "{"date":"10Mar","downloads":"26"}", "{"date":"09Mar","downloads":"7"}", "{"date":"08Mar","downloads":"5"}"]

现在，我要从此格式更改上面的数组格式:

Now, I want to change the above array format from this one:

["{"date":"07Apr","downloads":"1"}", "{"date":"06Apr","downloads":"3"}", "{"date":"05Apr","downloads":"12"}", "{"date":"04Apr","downloads":"11"}", ....]

到那个:

[{"date":"07Apr","downloads":"1"}, {"date":"06Apr","downloads":"3"}, {"date":"05Apr","downloads":"12"}, {"date":"04Apr","downloads":"11"}, ....]

我的意思是消除用大括号括住对象的双引号.

I mean to eliminate the double quotes that enclose the objects in curly braces.

任何想法将不胜感激...

Any ideas would be appreciated...

推荐答案

您可以解析从ajax响应接收到的数据以创建数组.

You can parse the data you received from the ajax response to create the array.

var populateArray = function (ajaxResponse) {
    var newArray = [];
    ajaxResponse.forEach(function (item, index) {
        var props = item.split('|');
        var obj = {
            date: props[0],
            downloads: props[1]
        };
        newArray.push(obj)
    });

    return newArray;
}

为演示，请尝试

console.log(populateArray(["07Apr|1", "06Apr|3", "05Apr|12", "04Apr|11", "03Apr|0", "02Apr|0", "01Apr|6", "31Mar|0", "30Mar|7", "29Mar|16", "28Mar|5", "27Mar|5", "26Mar|12", "25Mar|9", "24Mar|4", "23Mar|10", "22Mar|16", "21Mar|2", "20Mar|19", "19Mar|22", "18Mar|10", "17Mar|11", "16Mar|10", "15Mar|19", "14Mar|0", "13Mar|4", "12Mar|14", "11Mar|5", "10Mar|26", "09Mar|7", "08Mar|5"]));
