我想使用Javascript检查并验证范围上的某些数字,例如(1到6)。 我尝试过解决方案一和二,但无法让它工作。
解决方案1
var num =9;
if (!in_array(num, 1,6)){
alert('this number is not within the range);
}
解决方案2
var num =9;
if (num =>1 && num <=6){
alert('this number is okay);
} else{
alert('this number is not within the range);
}
答案 0 :(得分:0)
num&gt; = not num =&gt;
var num =9;
if (num >=1 && num <=6){
alert('this number is okay');
} else{
alert('this number is not within the range');
}
