一个for循环比较两个数组寻找匹配值 [英] A for-loop that compares two arrays looking for matching values

问题描述

我有两个数组，我需要核对对方，如果他们已经达到了一个点，每个阵列中的两个项目实际上是彼此相同，然后附加一些HTML的地方。

I have two arrays that I need to check against each other and if they have reached a point where both items in each array are actually the same as one another, then append some html somewhere.

下面是code的某些位我一直在努力作为一个例子：

Here are some bits of the code I have been trying as an example:

var daysArray = ["1", "2", "3", "4", "5"];
var courseHwork = ["4", "8", "15", "16", "23", "42"];

所以在上面的阵列，只有一个匹配值，作为：4

so in the arrays above there is only one matching value, being: "4"

这里的下一个部分：

for (var i = 0; i < courseHwork.length; i++) {
//in my actual code courseHwork contains several objects, each of which 
//has a duedate property, so here I want to see if this part of the duedate 
//property is equal to any position in the daysArray array.
   if (courseHwork[i].duedate.substring(8,10) === daysArray[i]) {
//here I mean to select an element of this class that contains a string 
//that is equal to that of the matching positions in both arrays. then 
//once found it should take the title property from one of the objects in the
//courseHwork array and append it there.
   $('.fc-day-number:contains("'+daysArray[i]+'")').append("<div class='assignment'>"+courseHwork[i].title+"</div><br />");
        }
        }

如果事情的来龙去脉按计划将找到一个div，包含字符串4，追加从courseHwork数组中的匹配对象属性称号。

If things worked as planned it will have found a div, that contains the string "4" and appended that property 'title' from the matching object in the courseHwork array.

请注意：我的实际daysArray涵盖数字为字符串1 - 31，和对象的courseHwork阵列的动态填充，因此它可以包含任意数量的对象，但没有对象将有超过31的属性值在子被发现。

note: my actual daysArray covers numbers as strings "1"-"31", and the courseHwork array of objects is dynamically populated so it can contain any number of objects, however no object will have a property value that exceeds "31" in the substring being found.

* 问：
我怎样才能通过两个数组的匹配值的两个阵列之间发现每一次循环，一个HTML元素被发现，还包含值完全相同，则已经附加的东西给它？的*

推荐答案

下面是想法，我想出了：

Here is idea i came up with:

var daysArray = ["1", "2", "3", "4", "5", "12"];
var courseHwork = ["4", "8", "15", "16", "23", "42", "12"];

for (var i = 0; i < courseHwork.length; i++) {
    for (var j = 0; j < daysArray.length; j++) {
        if (courseHwork[i] == daysArray[j]) {
          $('div:contains("'+daysArray[j]+'")').append("<div class='assignment'>"+courseHwork[i]+" - appended</div>");
        }
    }
}

好吧，看看如果你想要什么。首先，它会在2阵列相同的值，如果它发现它，它附加的东西div的含4在里面。这是你想要的吗？

Well, check if that what you want. First it looks for SAME value in 2 arrays, and if it finds it, it appends something to div containing "4" in it. Is that what you want?

下面是具有2相同的值，与2的div，每个包含的值的一个例子。
