在JavaScript中从JSON对象创建表 [英] Create table from JSON object in JavaScript
问题描述
我试图创建一个HTML表格,其中包含我用来绘制信息的HTML表格。
我不想查询数据库两次,我想创建图表和一个表的信息。
这是我从服务器得到的,并且它得到了图表:
I am trying to creat an HTML table with information I use to draw at flot. I dont want to query the database twice, and I want to creat the chart and a table with the information. This is what I get from the server and that it gets charted:
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"
}
}
]
};
由于组织信息的方式,我不能使用$ .each创建以下格式的表:
Because of the way the information is organized, I can not use $.each to loop over it and create a table of the format:
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 |
我认为最好的方法是读取对象并创建一个新的结构
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>';
但是这只会创建一个更简单的元素与我需要的信息,我需要。
But this only creats a more simple element with the information that I need, but still cant turn into what I need.
有人可以指点我的方向吗?
谢谢!
Can someone please point me in the right direction? Thanks!
推荐答案
这将将您的数据映射到表:
This will map your data to table:
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);
