Create table from JSON object in JavaScript
提问by Don Viegues
I am trying to create an HTML table with information I use to draw a plot. I don't want to query the database twice, and I want to create the chart and a table with the information. This is what I get from the server and that it gets charted:
我正在尝试使用用于绘制绘图的信息创建一个 HTML 表格。我不想两次查询数据库，我想创建图表和包含信息的表格。这是我从服务器得到的，并被绘制成图表：
var data = {
"selector":"#charttotalday",
"jsondata":[
{
"label":"Client1",
"data":[
[1382670000000,110157],
[1382756400000,199055],
[1382842800000,362996],
[1382929200000,302],
[1383015600000,169],
[1383102000000,88],
[1383188400000,49]
],
"points":{
"fillColor":"#88bbc8"
}
},
{
"label":"Client2",
"data":[
[1382670000000,58611],
[1382756400000,112268],
[1382842800000,193060],
[1382929200000,115],
[1383015600000,45],
[1383102000000,65],
[1383188400000,18]
],
"points":{
"fillColor":"#ed7a53"
}
},
{
"label":"Client3",
"data":[
[1382670000000,65534],
[1382756400000,118362],
[1382842800000,200058],
[1382929200000,123],
[1383015600000,65],
[1383102000000,53],
[1383188400000,26]
],
"points":{
"fillColor":"#9FC569"
}
}
]
};
Because of the way the information is organized, I can not use $.each to loop over it and create a table of the format:
由于信息的组织方式，我无法使用 $.each 循环遍历它并创建以下格式的表：
Client1 Client2 Client3
1382670000000 | 10157 | 58611 | 65534 |
1382756400000 | 99055 | 12268 | 18362 |
1382842800000 | 62996 | 93060 | 10058 |
1382929200000 | 302 | 115 | 123 |
1383015600000 | 169 | 45 | 65 |
1383102000000 | 88 | 65 | 53 |
1383188400000 | 49 | 18 | 26 |
I am thinking that the best way would be to read the object and create a new one with the structure that I need, that can be used with $.each.
我认为最好的方法是读取对象并创建一个具有我需要的结构的新对象，该结构可以与 $.each 一起使用。
I have tried with this:
我试过这个：
$.each(data.jsondata, function(key, value) {
thead += '<th>' + value.label + '</th>';
tableData[value.label] = new Object();
$.each(value.data, function(key1, value1) {
$.each(value1, function(key2, value2) {
if(key2 == 0) {
//here I have the time line, axis Y
index = value2;
}
if(key2 == 1) {
//here I have the values for the table
tableData[value.label][index] = value2;
}
});
});
});
thead += '</tr>';
But this only creates a more simple element with the information that I need, but still cant turn into what I need.
但这只会用我需要的信息创建一个更简单的元素，但仍然不能变成我需要的。
Can someone please point me in the right direction?
有人可以指出我正确的方向吗？

This will map your data to table:
这会将您的数据映射到表：
var headers=[ ""], rows={}
$.each(data.jsondata,function(clientIdx,item){
headers.push(item.label );
$.each( item.data,function(i,arr){
if( !rows[arr[0]]){
rows[arr[0]]=[];
}
rows[arr[0]][clientIdx]=arr[1];
})
})
var rowHtml='<tr><th>'+headers.join('</th><th>')+'</th></tr>';
$.each(rows,function(key, arr){
rowHtml+='<tr><td>'+key+'</td>';
rowHtml +='<td>'+arr.join('</td><td>')+'</td></tr>';
})
$('#table').html(rowHtml);
