如何将数组/值传递给Javascript函数 [英] How to pass Array/Values to a Javascript function

问题描述

我正在学习使用在线资源的项目的Javascript，但我不知道如何使这个功能正常工作。

I am learning Javascript for a project using online resources however i don't know how to get this function working.

var results =[[a1,a2,a3,a4,a5]];
var winner = 0;

function checkWinner (results)
{ 
  for (var i = 0; i < results.length; i++)
    if (results[0][i] > 50)
    {
      winner = results[0][i];

    }
}

在函数之后，我使用：
checkWinner（results）;

Just after the function, i use: checkWinner(results);

在HTML文件中，我使用alert来显示变量获胜者。但它显然不起作用。我意识到这是我对范围和全局变量的理解的问题。

In a HTML file i use alert to display the variable winner. But it obviously doesn't work. I realise it is a problem with my understanding of scope and global variables.

推荐答案

应

var Results =[[a1,a2,a3,a4,a5]];
var winner = 0;

function checkWinner (results)
{ 
  for (var i = 0; i < results[0].length; i++)
    if (results[0][i] > 50)
    {
      winner = results[0][i];

    }
}

checkWinner(Results);

为避免名称冲突，请从大写字母中命名全局变量。
同样在你的代码中，你调用父数组的长度。您需要指定Child数组的长度

To avoid name collisions name global variables from capital case. Also in your code you call the length of the "parent" array. You need to specify the length of the "Child" array
