当我按下按钮时一切都很好但是当按下它时它会触发该功能并在我的浏览器上快速返回，在它的最后一个按钮中。按下输入时我尝试了几种触发按钮的方法，但我遇到了同样的问题

function calculate() {
          
         
      var response = document.getElementById("text").value;
    
    if (response ==0 || response =="" || response >100 || response < 0) {
        alert('you should write a 0<number<100');
       
        
    } else{
    
     var start = new Date();
     var date = start.getFullYear();
        

    
   var result = date - response;
   
    x.innerHTML = 'Your Birth is '+ result;
    document.getElementById('ma').style.color = 'lightpink';   
    document.getElementById('ma').style.fontFamily = 'sans-serif';
    document.getElementById('ma').style.fontSize = "45px";
      
 
        
    } ;
    


  
  

};
