如何将用户数据加载到输入中？

Question

我正在尝试将已登录用户的数据加载到条目中，但是我不知道该怎么做。我是否必须使用诸如innerText之类的类似内容？

代码HTML：

<form>
        <h2 align="center">Setting</h2>
        <div class="form-group row">
            <label for="uidInput" class="col-sm-1 col-form-label">Uid</label>
            <div class="col-sm-4">
                <input type="text" class="form-control teste" id="uidInput" placeholder="uidInput">
            </div>
            <label for="emailInput" class="col-sm-1 col-form-label">Email</label>
            <div class="col-sm-4">
                <input type="email" class="form-control" id="emailInput">
            </div>
        </div>
        <div class="form-group row">
            <label for="nameInput" class="col-sm-1 col-form-label">Name</label>
            <div class="col-sm-4">
                <input type="text" class="form-control" id="nameInput">
            </div>
            <label for="passwordInput" class="col-sm-1 col-form-label">Password</label>
            <div class="col-sm-4">
                <input type="password" class="form-control" id="passwordInput">
            </div>
        </div>
        <div class="form-group row">
            <label for="surnameInput" class="col-sm-1 col-form-label">Surname</label>
            <div class="col-sm-4">
                <input type="text" class="form-control" id="surnameInput">
            </div>
        </div>
        <div class="form-group row">
            <label for="numberInput" class="col-sm-1 col-form-label">document number</label>
            <div class="col-sm-4">
                <input type="text" class="form-control" id="numberInput">
            </div>
        </div>
    </form>

代码js：

firebase.database().ref('/users/' + uid).once('value').then(function(snapshot) {
    var name = snapshot.val().name;
    var surname = snapshot.val().surname;
    var documentNumber = snapshot.val().documentNumber;
    var email = snapshot.val().email;
    var password = snapshot.val().password;

如果要从数据库中读取从HTML中读取的值，则可以使用以下方法设置元素的内部文本：

firebase.database().ref('/users/' + uid).once('value').then(function(snapshot) {
    var name = snapshot.val().name;
    var surname = snapshot.val().surname;
    var documentNumber = snapshot.val().documentNumber;
    var email = snapshot.val().email;
    var password = snapshot.val().password;

    document.querySelection('#emailInput').textContent = email;
    document.querySelection('#nameInput').textContent = name;
    document.querySelection('#passwordInput').textContent = password;
    document.querySelection('#surnameInput').textContent = surname;
    document.querySelection('#numberInput').textContent = documentNumber;
})
