Javascript 按th和行中第一个td进行的表映射，以从json对象填充

使用php内联回显json数组，我希望js/jquery根据这些数据填充表

HTML表格

<table>
<thead>
    <tr>
        <th>Time</th>
        <th data-day='2013-03-15'>15-3</th>
        <th data-day='2013-03-16'>16-3</th>
        <th data-day='2013-03-17'>17-3</th>
    </tr>    
</thead>
<tbody>
<tr data-time='09'>
    <td>9am</td>
    <td></td>
    <td></td>
    <td></td>
</tr>
</tbody>
</table>
<script>
var arr=[ 
 {"date":"2013-03-15","id":"4","time_booked":"09:00:00"},
 {"date":"2013-03-15","id":"1","time_booked":"09:10:00"},
 {"date":"2013-03-17","id":"5","time_booked":"09:30:00"}
];
$.each(arr,function(){
    console.log('id:'+this.id+'inside:'+this.date+'|'+this.time_booked);
});
</script>

但我觉得这很愚蠢！必须有一种方法可以使用x，y（表头，行头）映射表，否则就没有了？

我认为jQuery就是您想要的。在下面的代码示例中，我使用它获取日期的

colIndex

。在这种情况下，它获取表中的所有

th

单元格，并使用

.index（..）

和一个选择器来查找所需的日期。这给出了你正在寻找的日期的列索引，从那里开始，一切都很简单

var arr=[ 
 {"date":"2013-03-15","id":"4","time_booked":"0900"},
 {"date":"2013-03-15","id":"1","time_booked":"0910"},
 {"date":"2013-03-17","id":"5","time_booked":"0930"}
];
$.each(arr,function(){
    var cell = GetCellByDateAndTime(this.date, this.time_booked);
    $(cell).text(this.id);
});

function GetCellByDateAndTime(date, time) {
    var colIndex = $("#BookingsTable th").index($("[data-day='" + date + "']"));
    var row = $("#BookingsTable tr[data-time='" + time + "']")
    var cell = $(row).children($("td"))[colIndex];
    return cell;
}

还有一个

$.each(arr,function(){
    var rday=this.date;
    var rtime=this.time_booked;
    var sel='tr[data-hr="'+rtime.substr(0,2)+'"]';
    var dom=$(sel).find('td[data-day="'+rday+'"]').first();
    if(dom.length)dom.append(this.id);
});

var arr=[ 
 {"date":"2013-03-15","id":"4","time_booked":"0900"},
 {"date":"2013-03-15","id":"1","time_booked":"0910"},
 {"date":"2013-03-17","id":"5","time_booked":"0930"}
];
$.each(arr,function(){
    var cell = GetCellByDateAndTime(this.date, this.time_booked);
    $(cell).text(this.id);
});

function GetCellByDateAndTime(date, time) {
    var colIndex = $("#BookingsTable th").index($("[data-day='" + date + "']"));
    var row = $("#BookingsTable tr[data-time='" + time + "']")
    var cell = $(row).children($("td"))[colIndex];
    return cell;
}
