我一直在修改我发现的一段代码，但我不能让它按照我的意愿工作。这是当前的Javascript：
function JsonUtil() {
/**
* Given a provided object,
* return a string representation of the object type.
*/
this.isType = function (obj_) {
if (obj_ === null) {
return "null";
}
if (obj_ === NaN) {
return "Nan";
}
var _type = typeof obj_;
switch (_type) {
case "undefined":
return "undefined";
case "number":
return "number";
case "boolean":
return "boolean";
case "string":
return "string";
case "function":
return "function";
case "object":
if (this.isArray(obj_)) {
return "array";
}
return "associative";
}
},
/**
* Recursively search and display array as an HTML table.
*/
this.tableifyArray = function (array_) {
if (array_.length === 0) {
return "[ empty ]";
}
var _out = "<table class='arrayTable'>";
for(var i = 0; i < array_.length; i++) {
_out += "<tr class='arrayTr'><td class='arrayTd'>"
+ this.tableifyObject(array_[i]) + "</td></tr>";
}
_out += "</table>";
return _out;
},
/**
* Recursively search and display common javascript types as an HTML table.
*/
this.tableifyObject = function (obj_) {
/*
if (obj_ === '') {
return "[ empty ]";
}
*/
switch (this.isType(obj_)) {
case "null":
return "¡The data object is null!";
case "undefined":
return "undefined";
case "number":
return obj_;
case "boolean":
return obj_;
case "string":
return obj_;
case "array":
return this.tableifyArray(obj_);
case "associative":
return this.tableifyAssociative(obj_);
}
return "!error converting object!";
},
/**
* Recursively search and display associative array as an HTML table.
*/
this.tableifyAssociative = function (array_) {
if (this.isEmpty(array_)) {
return "{ empty }";
}
var _out = "<table class='associativeTable'>";
for (var _index in array_) {
_out += "<tr class='associativeTr'><td class='associativeTd'>"
+ this.tableifyObject(_index) + "</td><td class='associativeTd'>"
+ this.tableifyObject(array_[_index]) + "</td></tr>";
}
_out += "</table>";
return _out;
},
/**
* identify if an associative array is empty
*/
this.isEmpty = function (map_) {
for (var _key in map_) {
if (map_.hasOwnProperty(_key)) {
return false;
}
}
return true;
},
/**
* Identify is an array is a 'normal' (not associative) array
*/
this.isArray = function (v_) {
return Object.prototype.toString.call(v_) == "[object Array]";
},
/**
* given the desire to populate a map of maps, adds a master key,
* and child key and value to a provided object.
*/
this.addToMapOfMaps = function (map_, mkey_, key_, value_) {
if (map_ === undefined) {
map_ = {};
}
if (map_[mkey_] === undefined) {
map_[mkey_] = {}
}
if (map_[mkey_][key_] === undefined) {
map_[mkey_][key_] = null;
}
map_[mkey_][key_] = value_;
return map_;
}
}
这是CSS：
.arrayTable { border: 1px solid #c2c2c2; background-color: #c2c2c2; padding: 5px;}
.arrayTr { border: 1px solid #c2c2c2; background-color: #c2c2c2; padding: 5px;}
.arrayTd { border: 1px solid #c2c2c2; background-color: #c2c2c2; padding: 5px; vertical-align: top;}
.associativeTable { border: 1px solid #c2c2c2; background-color: #fff; padding: 5px;}
.associativeTr { border: 1px solid #c2c2c2; background-color: #fff; padding: 5px;}
.associativeTd { border: 1px solid #c2c2c2; background-color: #eee; padding: 5px; vertical-align: top;}
打电话给你只是做：
var json = new JsonUtil();
json.tableifyObject(jsonObject);
工作真的很棒，但不是我想要的，目前数组表显示如下：
NAME 123123
ID 1
CATEGORY 12412
NAME AAAA
ID 2
CATEGORY 2123
我想修改数组表的显示方式，垂直地需要它们以及一个表结构中的所有数据，而不是每个寄存器中的很多表。像这样：
NAME ID CATEGORY
123123 1 12412
AAAA 2 2123
如何更改递归Javascript以创建此类结果？
答案 0 :(得分：0)
做到了！如果_obj是一个数组，则添加代码以生成另一种类型的表。 万一有人需要同样的东西，这很有效！
function createTableBasedOnJsonArray(array_) {
var _out = "";
for(var index in array_) {
if(index == 0) {
_out += "<table class='arrayTable'><thead>";
//create thead
for(var key in array_[0]) {
_out += "<th>" + key + "</th>";
}
_out += "</thead>";
}
var values = array_[index];
//create tbody
_out += "<tbody><tr class='arrayTr'>";
for(var key in values) {
_out += "<td class='arrayTd'>" + values[key] + "</td>";
}
_out += "</tr>";
}
_out += "</tbody></table>"
return _out;
}
因此，JSON Object to HTML的整个json库现在如下：
function JsonUtil() {
/**
* Given a provided object,
* return a string representation of the object type.
*/
this.isType = function (obj_) {
if (obj_ === null) {
return "null";
}
var _type = typeof obj_;
switch (_type) {
case "undefined":
return "undefined";
case "number":
return "number";
case "boolean":
return "boolean";
case "string":
return "string";
case "function":
return "function";
case "object":
if (this.isArray(obj_)) {
return "array";
}
return "associative";
}
},
/**
* Recursively search and display array as an HTML table.
*/
this.tableifyArray = function (array_) {
if (array_.length === 0) {
return "[ empty ]";
}
var _out = createTableBasedOnJsonArray(array_);
return _out;
},
/**
* Recursively search and display common javascript types as an HTML table.
*/
this.tableifyObject = function (obj_) {
switch (this.isType(obj_)) {
case "null":
return "¡The data object is null!";
case "undefined":
return "undefined";
case "number":
return obj_;
case "boolean":
return obj_;
case "string":
return obj_;
case "array":
return this.tableifyArray(obj_);
case "associative":
return this.tableifyAssociative(obj_);
}
return "!error converting object!";
},
/**
* Recursively search and display associative array as an HTML table.
*/
this.tableifyAssociative = function (array_) {
if (this.isEmpty(array_)) {
return "{ empty }";
}
var _out = "<table class='associativeTable'>";
for (var _index in array_) {
_out += "<tr class='associativeTr'><td class='associativeTd'>"
+ this.tableifyObject(_index) + "</td><td class='associativeTd'>"
+ this.tableifyObject(array_[_index]) + "</td></tr>";
}
_out += "</table>";
return _out;
},
/**
* identify if an associative array is empty
*/
this.isEmpty = function (map_) {
for (var _key in map_) {
if (map_.hasOwnProperty(_key)) {
return false;
}
}
return true;
},
/**
* Identify is an array is a 'normal' (not associative) array
*/
this.isArray = function (v_) {
return Object.prototype.toString.call(v_) == "[object Array]";
},
/**
* given the desire to populate a map of maps, adds a master key,
* and child key and value to a provided object.
*/
this.addToMapOfMaps = function (map_, mkey_, key_, value_) {
if (map_ === undefined) {
map_ = {};
}
if (map_[mkey_] === undefined) {
map_[mkey_] = {}
}
if (map_[mkey_][key_] === undefined) {
map_[mkey_][key_] = null;
}
map_[mkey_][key_] = value_;
return map_;
}
}
function createTableBasedOnJsonArray(array_) {
var _out = "";
for(var index in array_) {
if(index == 0) {
_out += "<table class='arrayTable'><thead>";
//create thead
for(var key in array_[0]) {
_out += "<th>" + spaceRawKeyName(key).toUpperCase() + "</th>";
}
_out += "</thead>";
}
var values = array_[index];
//create tbody
_out += "<tbody><tr class='arrayTr'>";
for(var key in values) {
_out += "<td class='arrayTd'>" + values[key] + "</td>";
}
_out += "</tr>";
}
_out += "</tbody></table>"
return _out;
}
如果有人对“spaceRawKeyName”函数感兴趣，该函数用于通过大写锁定识别将此accountId的字符串分隔为account_Id。
function spaceRawKeyName(string) {
var newone = [];
for(i=0; i<string.length;i++) {
character = string.charAt(i);
if(character == character.toUpperCase()) {
newone.push("_");
}
newone.push(character);
}
var text = "";
for(i=0;i < newone.length;i++){
text += newone[i];
}
return text;
}
当然你可以稍后制作一个.toUpperCase（）让它看起来更加花哨ACCOUNT_ID，顺便说一句...如果你不想添加“_”，你可以简单地替换一个空格。
