您能告诉我如何从json对象中删除所有null和空字符串值吗?删除密钥时出现错误。
到目前为止,这是我所拥有的,但是不能正常工作:
$.each(sjonObj, function(key, value) {
if(value == "" || value == null) {
delete sjonObj.key;
}
});

您sjonObj.key
实际上是要删除。您需要使用数组访问符号:
delete sjonObj[key];
但是,这也将删除value等于0的地方,因为您没有使用严格的比较。使用===
来代替:
$.each(sjonObj, function(key, value){
if (value === "" || value === null){
delete sjonObj[key];
}
});
但是,这只会使对象浅走。要深入地做,可以使用递归:
(function filter(obj) {
$.each(obj, function(key, value){
if (value === "" || value === null){
delete obj[key];
} else if (Object.prototype.toString.call(value) === '[object Object]') {
filter(value);
} else if ($.isArray(value)) {
$.each(value, function (k,v) { filter(v); });
}
});
})(sjonObj);

}

})(sjonObj);
console.log(sjonObj)

请注意,如果您愿意使用lodash /
underscore.js之类的库,则可以_.pick
改用。但是,由于两个库都没有提供深层过滤功能,因此您仍然需要使用递归进行深层过滤。
sjonObj = (function filter(obj) {
var filtered = _.pick(obj, function (v) { return v !== '' && v !== null; });
return _.cloneDeep(filtered, function (v) { return v !== filtered && _.isPlainObject(v) ? filter(v) : undefined; });
})(sjonObj);
此变体具有保留原始对象不变的附加优点,但是它确实创建了一个全新的副本,如果您不需要原始对象,效率将会降低。
