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 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: -
谢谢!
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:--
Thanks!
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; }
