Question

我有Ajax和javascript，现在我正在将此模式获取到另一个页面或另一个单独的浏览器。

目前，我可以获取模式，但在模式显示之前，我需要它刷新页面。我如何才能做到而无需单击刷新。我已经进行了一些研究，并且看到了setInterval函数，但是我应该如何通过代码实现它呢，谢谢！我只想在模态显示之前不刷新页面。

在这里是我的模式形式，这是代码，而在我提交提交按钮之后

if ($count != 0) {
      while($row = mysqli_fetch_array($data)) { 
          echo '<div id="myModal" class="modal" style="position:fixed;  display: none; padding-top: 100px; 
          left: 0; top: 0; width: 100%; height: 100%; overflow: auto; background-color: rgb(0,0,0); background-color: rgba(0,0,0,0.9); ">
                <div class="container" style="width: 100%">
                <div class="card col-12" style="background-color: red; color: white;">
                <div class="card-header">
                    <p><h3 class="text-center">Announcement</h3></p>
                </div>
                  <div class="card-body text-center">
                      <h5>'.$row['additional_info'].'</h5>
                      <p>Please click refresh button to resume after the announcement</p>
                  </div>
                  </div>
                </div>
                <img class="modal-content" id="img01">
                </div>';
              $dataid = $row['id'];
      }
  }

这是我要在其中放置 setInterval 函数以使页面自动不刷新的脚本

document.getElementById('myModal').style.display='block';

目前，它没有任何特殊代码，只是我显示模态的方式，但需要刷新

我希望一旦我已经单击了提交按钮，就应该显示模态的输出。对于我的代码，按钮已经被单击，我只想插入setInterval函数以使模式显示而无需刷新页面

刷新

# ===============================
# = DATA SOURCE
# ===============================

# Set here configurations for the database connection

# Connection url for the database "netgloo_blog"

spring.datasource.url = jdbc:mysql://localhost:3306/auto_journey

# Username and password
spring.datasource.username = root
spring.datasource.password =auto123

# Keep the connection alive if idle for a long time (needed in production)
#spring.datasource.testWhileIdle = true
#spring.datasource.validationQuery = SELECT 1

# ===============================
# = JPA / HIBERNATE
# ===============================

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager).

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update): with "update" the database
# schema will be automatically updated accordingly to java entities found in
# the project
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy

# Allows Hibernate to generate SQL optimized for a particular DBMS
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
