Question

如何创建if语句以检查整数是否以0结尾？

例如，我想要这样的if语句：

var test = 107; //107 is an example it'should some unknown number

if(test is xx1 - xx9){
  //do something
}
else if(test is xx0){
  //do something
}

Answer 1

if (test % 10) {
    // does not end with 0
} else {
    // ends with 0
}

Answer 2

if(/0$/.test(number)) {
  /* it ends in a 0 */
}
else {
  /* it doesn't */
}

Answer 3

//使用模数

var test1 = 110

if（test1％10 == 0）{ } //数字以零结尾

Answer 4

      var test=107;
      var isEndsWithZero =test%10; 
      if(isEndsWithZero!==0)
      {
        //Ends With 1-9,Do something
        alert("Ends With 1 to 9");
      }
      else
      {
        //Ends With Zero ,Do something
        alert ("ends with zero");
      }

示例：

test=107;
isEndsWithZero=107%10 //7
Else part will get executed
