我有一个这样的变量：

deftemplate = {

};

我在这里有删除特定活动的代码：

function delact(event) {
var curact = parseInt(event.target.getAttribute("curact"));
deftemplate["activities"].splice(curact, 1);
for (var d = 0; d < deftemplate["tasks"].length; d++) {
    if (deftemplate["tasks"][d]["activity"] == curact) {
        for (var g = 0; g < deftemplate["tasks"][d]["equipments"].length; g++) {
            restoreCount2(deftemplate["tasks"][d]["equipments"][g][0], deftemplate["tasks"][d]["equipments"][g][1]);
        }

        for (var g = 0; g < deftemplate["tasks"][d]["manpower"].length; g++) {
            restoremCount2(deftemplate["tasks"][d]["manpower"][g][0], deftemplate["tasks"][d]["manpower"][g][1]);
        }

        for (var y = 0; y < deftemplate["tasks"].length; y++) {
            if (deftemplate["tasks"][y]["parent"] == d) {
                deftemplate["tasks"][y]["parent"] = null;
            }
            if (deftemplate["tasks"][y]["activity"] > curact) {
                console.log("Task Name: " + deftemplate["tasks"][y]["taskname"]);
                deftemplate["tasks"][y]["activity"]--;
            }
        }
        deftemplate["tasks"].splice(d, 1);
    }
}
loadacts($("#prjstartdate").val());
}

问题是任务通过索引连接到活动变量。当您删除＆＃34;活动＆＃34;中的特定活动时变量任务活动索引多于活动删除索引需要减少1再次安排到活动变量但我的代码似乎没有工作。我该如何修复此代码？

Answer 1

问题在于这一行

for

和for循环。删除项目时，下一个项目位于同一个插槽中。然后d递增索引，然后跳过索引。

结论：拼接后减少deftemplate["tasks"].splice(d, 1); d--;。

mmap failed: ENOMEM (Out of memory)

_{（我建议使用更好的数据结构。）}

Answer 2

它是你减少活动的for循环。如果我正在阅读正确的代码，问题是在按下按钮之后，每个活动都被删除。

解决方法是在完成删除项目后再执行另一个for循环，并减少那里的活动。您还需要使用d -

将d降低1

＆＃13;

var curact = parseInt(event.target.getAttribute("curact"));
deftemplate["activities"].splice(curact, 1);
for (var d = 0; d < deftemplate["tasks"].length; d++) {
    if (deftemplate["tasks"][d]["activity"] == curact) {
        for (var g = 0; g < deftemplate["tasks"][d]["equipments"].length; g++) {
            restoreCount2(deftemplate["tasks"][d]["equipments"][g][0], deftemplate["tasks"][d]["equipments"][g][1]);
        }

        for (var g = 0; g < deftemplate["tasks"][d]["manpower"].length; g++) {
            restoremCount2(deftemplate["tasks"][d]["manpower"][g][0], deftemplate["tasks"][d]["manpower"][g][1]);
        }

        for (var y = 0; y < deftemplate["tasks"].length; y++) {
            if (deftemplate["tasks"][y]["parent"] == d) {
                deftemplate["tasks"][y]["parent"] = null;
            }
        deftemplate["tasks"].splice(d, 1);
        d--;
    }
}
for(var y = 0; y < deftemplate["tasks"].length; y++){
  if (deftemplate["tasks"][y]["activity"] > curact) {
    console.log("Task Name: " + deftemplate["tasks"][y]["taskname"]);
    deftemplate["tasks"][y]["activity"]--;
  }
}

＆＃13;

Answer 3

如果要从数组中删除项目，则应该向后迭代。

for (var d = deftemplate["tasks"].length -1; d >= 0; d--) {
    // deftemplate["tasks"][d] can be removed...
}

拼接for循环并更改活动的索引号
