提问by Bootleg
For some reason this statement is skipping some data.Am I missing a continue statement somewhere or something ? Here is the code
出于某种原因，此语句正在跳过一些数据。我是否在某处或某处遗漏了 continue 语句？这是代码
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>';
}
}
}

Use a different variable on the inner loop, like jinstead of i.
在内部循环中使用不同的变量，例如j代替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 +

you are using "i" in your outer an inner loops. you need to use a different variable in the inner loop: i have used "inner" below as and example.
您在外部和内部循环中使用“i”。您需要在内循环中使用不同的变量：我在下面使用了“内部”作为示例。
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 inner = 0; inner < data.ORDER_STATUS[0].ORDERS[i].LEGS.length; inner ++) {
// do something
}
}
}
