如何解决“无法加载资源:服务器响应状态为404()”

标签: javascript html

当我单击cadastro.html上的exec cadastrarAluno()时,它将显示在控制台上:

加载资源失败:服务器响应状态为404()

cadastro.html:30未捕获的ReferenceError:在HTMLAnchorElement.onclick(cadastro.html:30)上未定义cadastrarAluno

如果我在没有Firebase托管的情况下在localhost上打开相同的文件,则xD看起来一切都很好我应该怎么做才能解决此问题?

function armazenaAluno(matricula, nome, turma, senha, nota = 'Nao realizado ainda') {
    await firebase.database().ref('alunos/' + turma + '/' + matricula).set({
        nome,
        turma,
        senha,
        nota,
    });
}

function validaCadastro(inputArray) {
    for (let input of inputArray) {
        if (input.value.length == 0) {
            alert('ERRO: Preencha todos os campos')
            return false
        }
    }
    if (inputArray[3].value != inputArray[4].value) {
        alert('ERRO: As senhas devem coincidir')
        return false
    }
    return true

}


async function cadastrarAluno() {
    let inputEls = document.getElementsByTagName('input')

    if (validaCadastro(inputEls)) {
        const matricula = inputEls[0]
        const nome = inputEls[1]
        const turma = inputEls[2]
        const senha = inputEls[3]
        await armazenaAluno(matricula, nome, turma, senha)
        window.open('https://herancasexual.firebaseapp.com/')
    }

}

这取决于为您的应用程序提供服务的内容。如果仅运行.html文件。尝试将代码修改为相对路径。如果您正在运行服务器,请尝试在src中给出绝对路径。例如:

相对而言 <script src="../src/functions.js" type="text/javascript">

绝对是 <script src="{Root_path}/src/functions.js" type="text/javascript">,根据您的服务器路径,根目录路径可以是localhost/bio2文件夹。
