        {
            alert("Select ER Type");
        }

推荐答案

innerHTML属性在IE中尝试添加或更新表单元素时出现问题，解决方法是创建一个div并设置附加到 DOM 之前的 innerHtml 属性:

The innerHTML property has some problems in IE when trying to add or update form elements, the workaround is to create a div and set the innerHtml property on that before appending to the DOM:

var newdiv = document.createElement("div");
newdiv.innerHTML = xmlhttp.responseText;
var container = document.getElementById(id);
container.appendChild(newdiv);
