在JS中检查字符串（数组）的回文列表 [英] Checking a list of Strings(Array) as palindrome in JS

问题描述

请解决我的问题，我将检查一个字符串列表作为回文，如果数组中的任何字符串是回文，那么它应该显示结果为true，结果应该是字符串值而不是布尔值。我尝试过很多次，但没有显示结果;看看我的代码如下：
$ b $ pre $ function checkPry（）
{
var status = new Array（） ;
var wordList1 = document.getElementById（tk）。value;
var wordArray = new Array（）;
wordArray = wordList1.split（）;
var alength = wordArray.length;
for（var i = 0; i< = alength; i ++）
{
var str = wordArray [i];
var chrlength = str.length;
var lw = chrlength - 1;
var chk =; （j = 0; j <= chrlength; j ++）
如果（str.charAt（j）！= str.charAt（（lw-j））

b {
chk =false;
休息;
}
else
{
chk =true;


if（chk ==true）
{
status [i] =true;
}
else if（chk ==false）
{
status [i] =false
}
}
var displayStr = status.toString（）;
document.getElementById（show）。innerHTML = displayStr;
}


如果我将输入值设为 [ dalad radar jaijai rexem] 然后它应该给结果为 [true，true，false，false] ，请帮助我;您还可以查看下面的小提琴： -

解决方案

 函数reverse（s）{
 return s.split（）。reverse（）。join（）; 
} 
 
函数checkIsPalindrome（arr）{
 var result = []; 
 for（var i = 0; i< arr.length; i ++）{
 result.push（arr [i] == reverse（arr [i]））; 
} 
返回结果; 
} 
  

Please solve my issue, I am going to check a list of strings as palindrome, if any of the string from the array is palindrome then it should display a result true, the result should be in string value not in Boolean value. I had tried so many times but it is not displaying the result; See my code below:-

function checkPry()
{
    var status = new Array();
    var wordList1 = document.getElementById("tk").value;
    var wordArray = new Array();
    wordArray = wordList1.split(" "); 
    var alength = wordArray.length; 
    for(var i=0; i <= alength; i++)
    {
        var str = wordArray[i];
        var chrlength = str.length;
        var lw = chrlength - 1;
        var chk = "";
        for(j=0; j<=chrlength; j++)
        {
            if(str.charAt(j) != str.charAt((lw - j)))
            {
                chk = "false";
                break;
            }
            else
            {
                chk = "true";
            }
        }
        if (chk == "true")
        {
            status[i] = "true";
        }
        else if (chk == "false")
        {
            status[i] = "false"
        }
    }
    var displayStr = status.toString();
    document.getElementById("show").innerHTML = displayStr;
}

like If I am giving the input value as [dalad radar jaijai rexem] then it should be give result as [true,true,false,false], Please help me in that; you can also check the fiddle below:--

解决方案

You just need to check if something reversed is the same

function reverse(s){
     return s.split("").reverse().join("");
}

function checkIsPalindrome(arr){
   var result=[];
   for(var i=0;i<arr.length;i++){
       result.push(arr[i]==reverse(arr[i]));
   }
   return result;
}
