  嗯..你可以使用javascript匹配函数与正则表达式来检查输入的格式...以下示例将检查地址是否至少包含一个数字 .

  var resultBox = document.getElementById("ifValid");
  
  function textboxChanged(){
      var address=document.getElementById("address").value;
      
      
      if (address.match(/[0-9]/i)==null){
          resultBox.style.color="red";
          resultBox.innerHTML="not valid";
      } else {
          resultBox.style.color="green";
          resultBox.innerHTML="valid";
      }
  
  }
  

  <input type="text" id="address" placeholder="enter an address" onkeyup="textboxChanged()">
      
  <p id="ifValid" style="color: red;">not valid</p>

  为什么不检查地址字符串开头的数字？

  var resultBox = document.getElementById("ifValid");
  
  function textboxChanged() {
    var address = document.getElementById("address").value;
  
    var parts = address.split(' ');
    if (parts.length > 1 && !isNaN(parts[0]) && parts[1].length > 0) {
      resultBox.style.color = "green";
      resultBox.innerHTML = "valid";
    } else {
      resultBox.style.color = "red";
      resultBox.innerHTML = "invalid";
    }
  
  }
  

  <input type="text" id="address" placeholder="enter an address" onkeyup="textboxChanged()">
  <p id="ifValid" style="color: red;">not valid</p>
