Question

上面的代码会将我重定向到所需的页面，但不会将数据输入数据库。

如果我删除14:27:50: Executing external task 'build'... :compileJava NO-SOURCE :processResources NO-SOURCE :classes UP-TO-DATE :jar UP-TO-DATE :assemble UP-TO-DATE :compileTestJava NO-SOURCE :processTestResources NO-SOURCE :testClasses UP-TO-DATE :test NO-SOURCE :check UP-TO-DATE :build UP-TO-DATE :b-features:compileJava UP-TO-DATE :b-features:processResources NO-SOURCE :b-features:classes UP-TO-DATE :b-features:jar SKIPPED /home/nikita/IdeaProjects/multi-project-reference/a-features/src/main/java/outerproject/A.java:3: error: package innerproject does not exist import innerproject.B; ^ /home/nikita/IdeaProjects/multi-project-reference/a-features/src/main/java/outerproject/A.java:7: error: cannot find symbol B b = new B(); ^ symbol: class B location: class A /home/nikita/IdeaProjects/multi-project-reference/a-features/src/main/java/outerproject/A.java:7: error: cannot find symbol B b = new B(); ^ symbol: class B location: class A 3 errors :a-features:compileJava FAILED FAILURE: Build failed with an exception.命令，则数据已成功输入数据库。

我想一起完成这两项任务。出路是什么？

window.location.href

Answer 1

您可以使用提及here的承诺来确定将用户重定向到Votingpage.html的安全时间

firebasep.set(newData).then(function(data){
  alert("New");
  window.location.href="Votingpage.html";
}).catch(function(error){
  console.log(error);
});

Answer 2

它会将您重定向到所需的页面，但不会将数据输入数据库，因为查询失败但您错误地将重定向代码放在错误回调中，修复了这样的代码，以便更清楚地看到发生了什么

firebase.set(newData)
  .then((data) => {
      // redirect here
  })
  .catch((error) => {
     // display error here
  });

在页面重定向上没有数据输入firebase数据库
