我想显示foreach子行数据表
假设我有像这样的ajax数据
"data": [
{
"date" : "1/17/2016",
"supplier" : "supplier1",
"total" : "$10",
"payment" : "Cash",
"product" : Array[2]
0: "product1"
1: "product2"
"price" : Array[2]
0: "$5"
1: "$5"
},
{
"date" : "2/1/2016",
"supplier" : "supplier2",
"total" : "$3",
"payment" : "Cash",
"product" : Array[1]
0: "product1"
"price" : Array[1]
0: "$3"
},
{
"date" : "1/17/2016",
"supplier" : "supplier3",
"total" : "$15",
"payment" : "Cash",
"product" : Array[3]
0: "product1"
1: "product2"
2: "product3"
"price" : Array[2]
0: "$3"
1: "$5"
2: "$7"
},
我想在链接here之后为product & price
数组创建数据表子行
我只编辑function format
中的脚本以满足我的需求
function format ( d ) {
// `d` is the original data object for the row
return '<table class="table table-border table-hover">'+
'<tr>'+
'<td>Product</td>'+
'<td>Price</td>'+
'</tr>' +
'<?php
$loop = 5;
echo $loop; <-- here
for ($i=0; $i<$loop; $i++) {
echo "<tr><td>'+d.product['$i']+'</td> <td>'+d.price['$i']+'</tr>";
} ?>' +
'</table>';
}
它运行得很好......我可以显示我想要的数据......但我必须定义$loop
手册......
我尝试使用$loop = "'+d.product.length+'"
当我echo
知道它的变量时,它显示实际值
(说我3
product
数组3
也显示for
但不知何故,当它进入$loop
部分时,$i<=$loop
变为0
因为不显示任何行(如果我将条件设置为$loop = "'+d.product_.length+'" . "'+d.product_.length+'"
,那么每行父母中显示一行详细信息)
我发现了一些奇怪的东西
echo $loop
;
33
==&gt; 3
(例如,如果产品数组计数为sum
)
但如果我将其更改为0
,则结果为$loop = "'+d.product_.length+'" + "'+d.product_.length+'"
echo $loop
;
0
==&gt; 3
(如果产品数组计数也是{{1}})
如何解决它,所以我可以知道我的脚本应该循环多少
答案 0 :(得分:5)
你真的不需要php
在这里添加一个循环附加表,而是可以使用jquery
&#39; s $.each
..你只需要在append
之前构建表体结构,如下所示:
/* Formatting function for row details - modify as you need */
function format ( d ) {
console.log(d.product);
var trs=''; //just a variable to construct
$.each($(d.product),function(key,value){
trs+='<tr><td>'+value+'</td><td>'+d.price[key]+'</td></tr>';
//loop through each product and append it to trs and am hoping that number of price
//values in array will be equal to number of products
})
// `d` is the original data object for the row
return '<table class="table table-border table-hover">'+
'<thead>'+
'<th>Product</th>'+
'<th>Price</th>'+
'</thead><tbody>'
+ trs +
'</tbody></table>';
}
$(document).ready(function() {
var table = $('#example').DataTable({
"ajax": 'https://raw.githubusercontent.com/kshkrao3/JsonFileSample/master/Employees.json',
"columns": [
{
"class": 'details-control',
"orderable": false,
"data": null,
"defaultContent": ''
},
{ "data": "date"},
{ "data": "supplier"},
{ "data": "total"},
{ "data": "payment"}
]
});
// Add event listener for opening and closing details
$('#example tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var row = table.row( tr );
if ( row.child.isShown() ) {
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
}
else {
// Open this row
row.child( format(row.data()) ).show();
tr.addClass('shown');
}
});
});
注意:您的
click event
出现了错误。由于您在dTable.row
中持有引用,因此您必须table.row
尝试table
变量。
