Question

代码链接：http://jsbin.com/lozifokuzi/1/edit?html,js,output应该显示16个单词，但它只显示15个单词（用希伯来语写的单词）。代码用JavaScript和jQuery语言编写。

$(document).ready(function () {
// creat array of objects, DetermineIDs
var words = new Array(16);
for (var i = 0; i < words.length; i++) {
    words[i] = new Object();
    words[i].id = i + 1;
}
                
//insert into objects words
               
words[0].word = "קוף";
words[1].word = "קוף";
words[2].word = "אריה";
words[3].word = "אריה";
words[4].word = "נמר";
words[5].word = "נמר";
words[6].word = "טלפון";
words[7].word = "טלפון";
words[8].word = "מחשב";
words[9].word = "מחשב";
words[10].word = "מקלדת";
words[11].word = "מקלדת";
words[12].word = "אוגר";
words[13].word = "אוגר";
words[14].word = "עכבר";
words[15].word = "עכבר";
//Determine locations

有人可以帮忙吗？

Answer 1

你在函数Random（）中有17个循环：

   while ((random < 1 || random > 17) || RandomC(ezer, random)) 
   {
      random = parseInt(Math.random() * 100);
   }

使它成为16：

   while ((random < 1 || random > 16) || RandomC(ezer, random)) 
   {
      random = parseInt(Math.random() * 100);
   }

你的问题是你有16个元素从1到16，你的随机函数给出16个随机数从1到17，如果返回范围有数字17它缺少从1到16的东西，这意味着你的p元素那个nubmer没有充满内容。
