Question

我有一个java地图，我将其转换为json。这就是我的脚本的样子

var newVar = '[';

for(var x in pdict.Stores){
    newVar += '{' + '"Store_ID":"' + x.ID + '",';
    newVar += '"inv list id":"' + x.inventoryList.ID + '",';
    newVar += '"Store Address":"' + x.address1 + '",';
    newVar += '"zip":"' + x.postalCode + '"},';
}

newVar += ']';

pdict.Stores正在给我一张地图。在进行连接时，最后一个逗号被添加到json的末尾，json变得无效。如何在']'

关闭之前删除最后一个'，'

这是输出

[{"Store_ID":"46305","inv list id":"jonesny-46305-inventory","Store Address":"739 Reading Avenue Suite #306","zip":"19610"},{"Store_ID":"48760","inv list id":"jonesny-46305-inventory","Store Address":"1665 State Hill Rd","zip":"19610"},{"Store_ID":"48811","inv list id":"jonesny-46305-inventory","Store Address":"1665 State Hill Road","zip":"19601"},{"Store_ID":"53046","inv list id":"jonesny-46305-inventory","Store Address":"2630 Westview Dr","zip":"19610"},]

我不能使用jquery。它必须是基于javascript的解决方案。

不要这样做。

创建一个新对象，将其构建出来，并使用stringify将其序列化。

var a = [];
for(var x in pdict.Stores){
    var b = {};
    b.Store_ID = x.id;
    b["inv list id"] = x.inventoryList.ID;
    b["Store Address"] = x.address1;
    b.zip = x.postalCode;
    a.push(b);
}

return JSON.stringify(a);

如何从json中删除一个额外的'，'
