[英]How to map Nested JSON to an HTML table using Javascript
I have JSON Data from an API which contains users at different locations. 我有一个来自API的JSON数据,该API包含位于不同位置的用户。 I want to map it to an HTML table that looks like the one shared below. 我想将其映射到看起来像下面共享的HTML表。
JSON DATA: JSON数据:
{
"data": [{
"location": "Location 1",
"Address": "location 1, Address",
"users": [{
"name": "Location 1 User",
"state": "Active"
}]
}, {
"location": "Location 2",
"Address": "Location 2, Address",
"users": [{
"name": "Location 2 User",
"state": "Active"
},
{
"name": "Location 2 User",
"state": "Inactive"
}
]
}]
}
If you notice in the third column, both users of the second location are added inside one td element and are listed in one cell. 如果您在第三列中注意到,则第二个位置的两个用户都被添加到一个td元素内,并在一个单元格中列出。 I want to transform my JSON to this sort of table with RAW Javascript. 我想用RAW Javascript将JSON转换为这种表。
I have tried different ways but no luck so any help on this would be appreciated! 我尝试了不同的方法,但是没有运气,因此,对此将有所帮助!
Thank you! 谢谢!

<script>
json_data =
{
"data": [{
"location": "Location 1",
"Address": "location 1, Address",
"users": [{
"name": "Location 1 User",
"state": "Active"
}]
}, {
"location": "Location 2",
"Address": "Location 2, Address",
"users": [{
"name": "Location 2 User",
"state": "Active"
},
{
"name": "Location 2 User",
"state": "Inactive"
}
]
}]
}
//Accessing the JSON Document using these loops
Object.keys(json_data['data']).forEach(key => {
var tr = document.createElement('tr');
tr.className = 'cell'
document.getElementsByTagName('tbody')[0].appendChild(tr);
Object.keys(json_data['data'][key]).forEach(key2 => {
var td = document.createElement('td');
td.setAttribute('colspan', '2');
if (key2 === 'users') {
Object.keys(json_data['data'][key][key2]).forEach(key3 => {
if (key3 > 0) {
td.innerHTML = td.innerHTML + ', ' + json_data['data'][key][key2][key3]['name'];
}
else {
td.innerHTML = td.innerHTML + json_data['data'][key][key2][key3]['name'];
}
})
}
else {
td.innerHTML = json_data['data'][key][key2];
}
document.getElementsByClassName('cell')[key].appendChild(td);
})
});
</script>
the code is pretty straightforward. 该代码非常简单。 The main thing to take note of is the Object.keys().forEach() loops and the createElements 要注意的主要事情是Object.keys()。forEach()循环和createElements
There could be a much easier way to do this, but hey, it works. 可能有一种更简单的方法来执行此操作,但是,它确实有效。
