如何清除Web表单中的所有文本框？(名称“form1”在当前上下文中不存在)

var form = document.getElementById("form1");

var form = document.querySelector("#form1");

var form = document.getElementById("form1");
var elements = form.elements;
for(var i = 0; i < elements.length; i++){
  var element = elements[i];
  if(element.type === "text" || element.type === "password" || element.type === "email"){
    element.value = "";
  }
}

var form = document.getElementById("form1");
var elements = form.elements;
Array.from(elements).forEach(function(element){
  if(element.type === "text" || element.type === "password" || element.type === "email"){
    element.value = "";
  }
});
