是什么原因造成“未捕获的SyntaxError：意外的令牌O”与$ .parseJSON（）和JSON.parse（） [英] What is causing “Uncaught SyntaxError: Unexpected token o” with $.parseJSON() and JSON.parse()

问题描述

我到处都找过SO和谷歌但也指出，已帮助，我不知道该如何继续。我有我从一个PHP页面中使用返回一个数组回声json_en code（），看起来像这样：

I Have looked all over SO and Google but have have noting that has helped and I'm unsure how to continue. I have an array which I am returning from a php page using echo json_encode() that looks like this:

[" "," "," "," "," ",1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31]

但我不断收到意外标记Ø在Object.parse（本机）当我尝试使用JSON.parse（）来和意外标记Ø在Function.parse（本机）当我使用JQuery的alternitive。

but I keep getting Unexpected token o at Object.parse (native) when I try to use JSON.parse() and Unexpected token o at Function.parse (native) when I use the JQuery alternitive.

但是当我只是其附加到 $范围我可以使用页面上打印出来，所以我在做什么错了，我该怎么纠正呢？

but when I just attach it to the $scope I can print it out using on the page, so What am I doing wrong and how can I correct this?

这是我的控制器

function myController($scope, memberFactory) {

    response = memberFactory.getMonth("2013-08-01 06:30:00");
    //$scope.response = response;
    var monthDays = $.parseJSON(response);

    var dates = [];
    for (var i = 0; i < monthDays.length; i++) {
        if (i % 7 == 0) dates.push([]);
        dates[dates.length - 1].push(monthDays[i]);
    }
    $scope.dates = dates;
    //
}

这是我的服务方式：

obj.getMonth = function (date) {
    var month = $q.defer();
    $http.get('getMonth.php?date=' + date)
        .success(function (data, status, headers, config) {
        month.resolve(data);

    });

    return month.promise;
}

这是我的PHP：

and this is my php:

<?php $daysOfMonth=[ " ", " ", " ", " ", " ",1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31];
echo json_encode($daysOfMonth); ?>

的事情我都试过

如果我回到了的typeof 我得到的对象，所以后来我试图 VAR monthDays = Array.prototype.slice.call（响应）和 VAR monthDays = $ .MAP（响应函数（值，键）{返回值;}）; 在一些答案建议< A HREF =htt​​p://stackoverflow.com/questions/3865139/cast-javascript-object-to-array-how-to>这里，我也曾尝试 JSON.stringify （），但我只是得到 {} 的结果

Things I have Tried

If I return the typeof I get Object, so I have then tried var monthDays = Array.prototype.slice.call(response) and var monthDays = $.map(response, function (value, key) { return value; });as suggested in some of the answers here, I have also tried JSON.stringify() but I just get {} as the result

我真的很沮丧，这真的是需要有人点我在正确的方向

I am really frustrated with this an really need someone to point me in the correct direction

我认为这可能是使用问题 $ q.defer（），因为我更新了我的getMonth方法如下：

I believe this may be an issue with using $q.defer() as I updated my getMonth Method as follows:

obj.getMonth = function (date) {
    var month = $q.defer();
    $http.get('getMonth.php?date=' + date)
        .success(function (data, status, headers, config) {
        month.resolve(data);
        console.log("data " + data[0]);
        console.log("resolved " + month.promise[0]);

    });

    return month.promise;
}   

现在我得到 1 为的console.log（数据+数据[0]）; 预期但我得到了的console.log（月）; 我得到 [对象的对象] 为的console.log（month.promise）我得到 [对象的对象] 和的console.log（month.promise [ 0]）; 我得到未定义

now I get 1 for console.log("data " + data[0]); as expected but I get for console.log(month); I get [object Object] forconsole.log(month.promise) I get [object Object]and for console.log(month.promise[0]); I get undefined

推荐答案

响应已经被解析，你不需要再解析它。

response is already parsed, you don't need to parse it again.

如果您再次解析它，所以你要分析它会首先执行一个toString铸

If you parse it again it will perform a toString-cast first so you're parsing

"[object Object]"

这也解释了意外的标记0 。
