在HTML表中绑定jSon数据

Question

我正在尝试导入excel数据，并最终将其绑定到HTML表。目前，它是有效的，但我对数据绑定做了一点更改，不幸的是无法按预期绑定数据。以下是我迄今为止尝试过的带有示例jSon数据的代码片段：

var data = [{
ID: "1002",
EMAIL: "[e-mail]"
},
{
ID: "1004",
EMAIL: "[e-mail]"
},
{
ID: "1006",
EMAIL: "[e-mail]"
},
{
ID: "1008",
EMAIL: "[e-mail]"
}
];
var table = document.createElement("table");
table.border = "1";
var cell = "";
var row = table.insertRow(-1);
//Add the header cells
var headerCell = document.createElement("TH");
headerCell.innerHTML = ("ID");
row.appendChild(headerCell);
headerCell = document.createElement("TH");
headerCell.innerHTML = ("EMAIL");
row.appendChild(headerCell);
data.forEach(function(obj) {
//Get an array of all available keys in current element
var keys = Object.keys(obj);
//Loop through all obtained keys
keys.forEach(function(key) {
//The following line will match ID/IDS/id/ids
if (key.toUpperCase().indexOf("ID") > -1) {
//Add the data cells
cell = table.insertRow(-1).insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found ids: ", obj[key]);
}
//The following line will match AMOUNT/AMOUNTS/amount/amounts
if (key.toUpperCase().indexOf("EMAIL") > -1) {
//Add the data cells
cell = table.insertRow(-1).insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found emails: ", obj[key]);
}
});
});
var dvExcel = document.getElementById("excelTable");
dvExcel.innerHTML = "";
dvExcel.appendChild(table);

<div id="excelTable"></div>

问题是，我拥有的数据格式如下：

ID       EMAIL
1002
[e-mail]
1004
[e-mail]

预期输出：

ID     EMAIL
1002   [e-mail]
1004   [e-mail]

Answer 1

正如其他人已经说过的，您需要移动行创建

这是一个更简单的版本

var data = [
{ ID: "1002", EMAIL: "[e-mail]" },
{ ID: "1004", EMAIL: "[e-mail]"},
{ ID: "1006", EMAIL: "[e-mail]"},
{ ID: "1008", EMAIL: "[e-mail]"}
];
document.getElementById("excelTable").innerHTML = [
'<table border="1"><thead>', 
...Object.keys(data[0]).map(key => `<th>${key}</th>`),
'</thead><tbody>', 
...data.map(item => `<tr><td>${item.ID}</td><td>${item.EMAIL}</td></tr>`),
'</tbody></table>']
.join("")

<div id="excelTable"></div>

问题是在插入新单元格的同时创建新行，请尝试我们创建一行的方法

var data = [{
ID: "1002",
EMAIL: "[e-mail]"
},
{
ID: "1004",
EMAIL: "[e-mail]"
},
{
ID: "1006",
EMAIL: "[e-mail]"
},
{
ID: "1008",
EMAIL: "[e-mail]"
}
];
var table = document.createElement("table");
table.border = "1";
var cell = "";
var row = table.insertRow(-1);
//Add the header cells
var headerCell = document.createElement("TH");
headerCell.innerHTML = ("ID");
row.appendChild(headerCell);
headerCell = document.createElement("TH");
headerCell.innerHTML = ("EMAIL");
row.appendChild(headerCell);
data.forEach(function(obj) {
//Get an array of all available keys in current element
var keys = Object.keys(obj);
//Loop through all obtained keys
keys.forEach(function(key) {
//The following line will match ID/IDS/id/ids
if (key.toUpperCase().indexOf("ID") > -1) {
//Add the data cells
row = table.insertRow(-1);
cell = row.insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found ids: ", obj[key]);
}
//The following line will match AMOUNT/AMOUNTS/amount/amounts
if (key.toUpperCase().indexOf("EMAIL") > -1) {
//Add the data cells
cell = row.insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found emails: ", obj[key]);
}
});
});
var dvExcel = document.getElementById("excelTable");
dvExcel.innerHTML = "";
dvExcel.appendChild(table);

<div id="excelTable"></div>

您正在为所有键创建行，在外循环中移动您的行

var data = [{
ID: "1002",
EMAIL: "[e-mail]"
},
{
ID: "1004",
EMAIL: "[e-mail]"
},
{
ID: "1006",
EMAIL: "[e-mail]"
},
{
ID: "1008",
EMAIL: "[e-mail]"
}
];
var table = document.createElement("table");
table.border = "1";
var cell = "";
var row = table.insertRow(-1);
//Add the header cells
var headerCell = document.createElement("TH");
headerCell.innerHTML = ("ID");
row.appendChild(headerCell);
headerCell = document.createElement("TH");
headerCell.innerHTML = ("EMAIL");
row.appendChild(headerCell);
data.forEach(function(obj) {
//Get an array of all available keys in current element
var keys = Object.keys(obj);
var row =  table.insertRow(-1);
//Loop through all obtained keys
keys.forEach(function(key) {

//The following line will match ID/IDS/id/ids
if (key.toUpperCase().indexOf("ID") > -1) {
//Add the data cells
cell =row.insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found ids: ", obj[key]);
}
//The following line will match AMOUNT/AMOUNTS/amount/amounts
if (key.toUpperCase().indexOf("EMAIL") > -1) {
//Add the data cells
cell = row.insertCell(-1);
cell.innerHTML = obj[key];
//console.log("found emails: ", obj[key]);
}
});
});
var dvExcel = document.getElementById("excelTable");
dvExcel.innerHTML = "";
dvExcel.appendChild(table);

<div id="excelTable"></div>
