For循环里面For循环Javascript [英] For loop inside For Loop Javascript

问题描述

（var i = 0，len = data.ORDER_STATUS [0] .ORDERS.length; i< len; i ++）{
if（data.ORDER_STATUS [ 0] .ORDERS [i] .SEC_TYPE ==MLEG）{
for（var i = 0; i< data.ORDER_STATUS [0] .ORDERS [i] .LEGS.length; i ++）{
LEGS + ='< tr class =MLEGS>< td class =orderFirst>'+
data.ORDER_STATUS [0] .ORDERS [i] .LEGS [i]。 SYMBOL +
'< / td>< td>'+ data.ORDER_STATUS [0] .ORDERS [i] .LEGS [i] .ACTION +
'< / td>< td> 'data.ORDER_STATUS [0] .ORDERS [i] .LEGS [i] .QTY +
'< / td>< td>< / td>< td>< / td> < TD>< / TD>< TD>< / TD>< TD>< / TD>< TD>< / TD>< TD>< / TD>< / TR> ;





$ p $由于某些原因，跳过一些数据。我在某处丢了一个continue语句吗？

解决方案在内部循环中使用一个不同的变量，比如 j 而不是 i 。

  （var i = 0，len = data.ORDER_STATUS [0] .ORDERS.length; i< len; i ++）{
 // ... 
 
 for（var j = 0; j< data.ORDER_STATUS [0] .ORDERS [i] .LEGS.length; j ++）{
 // ... 
 data.ORDER_STATUS [0] .ORDERS [i] .LEGS [j] .SYMBOL + 
  

for (var i = 0, len=data.ORDER_STATUS[0].ORDERS.length; i < len; i++) {
     if (data.ORDER_STATUS[0].ORDERS[i].SEC_TYPE=="MLEG") {
           for (var i = 0; i < data.ORDER_STATUS[0].ORDERS[i].LEGS.length; i++) {
                 LEGS +='<tr class="MLEGS"><td class="orderFirst">' +
                 data.ORDER_STATUS[0].ORDERS[i].LEGS[i].SYMBOL +
                 '</td><td>' + data.ORDER_STATUS[0].ORDERS[i].LEGS[i].ACTION +
                 '</td><td>' + data.ORDER_STATUS[0].ORDERS[i].LEGS[i].QTY +
                 '</td><td></td><td></td><td></td><td></td><td></td><td></td><td></td></tr>';
           }
     }
}

For some reason this statement is skipping some data. Am I missing a continue statement somewhere or something?

解决方案

Use a different variable on the inner loop, like j instead of i.

for (var i = 0, len=data.ORDER_STATUS[0].ORDERS.length; i < len; i++) {
    //...

   for (var j = 0; j < data.ORDER_STATUS[0].ORDERS[i].LEGS.length; j++){
       //...
       data.ORDER_STATUS[0].ORDERS[i].LEGS[j].SYMBOL +
