Javascript Ngfor对象列表,并从主数组中一个对象内的数组再次循环
嗨,我有以下数据结构Javascript Ngfor对象列表,并从主数组中一个对象内的数组再次循环,javascript,jquery,html,angular,typescript,Javascript,Jquery,Html,Angular,Typescript,嗨,我有以下数据结构 this._days=[ { "day": "", "timing": {} }, { "day": "Monday", "timing": [ {'9:00AM-10:00AM': {'subject': 'Physics','teac
this._days=[
{
"day": "",
"timing": {}
},
{
"day": "Monday",
"timing": [
{'9:00AM-10:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'10:00AM-11:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'11:00AM-12:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'12:00AM-13:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'13:00AM-14:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}}
]
},
{
"day": "Tuesday",
"timing": [
{'9:00AM-10:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'10:00AM-11:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'11:00AM-12:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'12:00AM-13:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}},
{'13:00AM-14:00AM': {'subject': 'Physics','teacher': 'Amanda','Location': 'Room 05'}}
]
},
...
我想显示如下的值
在我的html中,我尝试
<table width="100%" align="center" height=100%;>
<tr class="day">
<th *ngFor="let row of _days">{{row.day}}</th>
</tr>
<tr class="time" *ngFor="let x of _days.timing">
<th style="width:100px">{{_days.timing[x][key]}}</th>
<td>{{_days.timing[x].value}}</td>
</tr>
</table>
无论如何,我可以在我的html中实现这一点,这样我就可以得到如图所示的预期结果。提前感谢各位。首先,您需要根据时间筛选数据
var tabelRows = {};
var firstRow = [];
_days.forEach(function(v,i){
v.timing.forEach(function(val,ind) {
var row = Object.keys(val)[0];
if(firstRow.indexOf(row) == -1) {
firstRow.push(row);
tabelRows[row] = [val[row]];
} else {
tabelRows[row].push(val[row]);
}
});
});
然后执行forEach循环,您可以执行以下操作:
<tr class="time" *ngFor="let x of firstRow">
<th style="width:100px">{{x}}</th>
<td *ngFor="let y of tabelRows[x]">{{y.subject}}</td>
</tr>
这里你错了这里你分配了_天。时间什么都不是
