Question

如下所示，我正在尝试使用undercorejs中的-.each函数来分配json文件中每条记录的值并将其打印到屏幕上..我有这段代码，但它不起作用......任何想法为什么？

var ty = [{
    "Language": "en-GB",
"Section": "Sales&Marketing",
"ItemName": "CalculationType",
"Texts": "Having selected the account heading select the calculation ..."},
{"Language": "en-GB",
"Section": "Taxes",
"ItemName": "Save",
"Texts": "The Master Tax Table has been pre populated with the current UK, ..."}
];

arr= {};
_.each(ty, function(val,key) {
   arr[key] = val;
});
log(arr);

我认为CDN的问题。如果您需要语言，则需要指定val.Language。并且数组定义也是错误的。给new Array或[]而不是{}。请尝试以下方法：

＆＃13;

function log(contents) {
var result='';
if(_.isArray(contents)) {
    _.each(contents, function(e, i, l) {
        //log(e);
        result += e.Language+'-'+e.Section+'-'+e.ItemName+'-'+e.Texts+'</br>';
    });
} 
return result;
};


var ty = [{
"Language": "en-GB",
"Section": "Sales&Marketing",
"ItemName": "CalculationType",
"Texts": "Having selected the account heading select the calculation ..."},
{"Language": "en-GB",
"Section": "Taxes",
"ItemName": "Save",
"Texts": "The Master Tax Table has been pre populated with the current UK, ..."}
];

arr= new Array;
_.each(ty, function(val,key) {
   arr[key] = val;
});
var res=log(arr);
$('#result').append(res);

underscorejs每个函数都不起作用
