javascript - 如何使用javascript插入换行符？

Question

我的提交表单包含姓名、电子邮件和电话号码字段。当然，我想在三者之间插入换行符。我试图在所有三个之间插入一个换行符，但只在表单末尾生成一个换行符，而我的代码应该附加 3 个换行符，而不是一个。

生成的 View 源显示如下:

<label>Name: </label><input required="" name="fullName" type="text"><label>Email: </label>   <input required="" name="email" type="text"><label>Phone Number: </label><input required="" name="phoneNumber" type="text"><br><input value="Submit Query" type="submit"></form>

生成此表单的 Javascript 代码:

function queryForm()
{
    var queryBox = document.getElementById("queryBox").style.display = "block";
    var queryForm = document.getElementById("queryForm");
    var linebreak = document.createElement("br");

    var lblName = document.createElement("label");
    lblName.textContent = "Name: ";
    queryForm.appendChild(lblName);

    var fullName = document.createElement("input");
    fullName.name = "fullName";
    fullName.type = "text";
    fullName.required = "required";
    queryForm.appendChild(fullName);
    queryForm.appendChild(linebreak);


    var lblEmail = document.createElement("label");
    lblEmail.textContent = "Email: ";
    queryForm.appendChild(linebreak);
    queryForm.appendChild(lblEmail);

    var email = document.createElement("input");
    email.name = "email";
    email.type = "text";
    email.required = "required";
    queryForm.appendChild(email);


    var lblPhoneNumber = document.createElement("label");
    lblPhoneNumber.textContent = "Phone Number: ";
    queryForm.appendChild(linebreak);
    queryForm.appendChild(lblPhoneNumber);

    var phoneNumber = document.createElement("input");
    phoneNumber.name = "phoneNumber";
    phoneNumber.type = "text";
    phoneNumber.required = "required";
    queryForm.appendChild(phoneNumber);


    var submitQuery = document.createElement("input");
    submitQuery.type = "submit";
    submitQuery.value = "Submit Query";
    queryForm.appendChild(linebreak);
    queryForm.appendChild(submitQuery);
}

Answer 1

您应该创建新的 <br>每次附加它时标记，例如

linebreak = document.createElement("br");
queryForm.appendChild(linebreak);
