本文详细介绍了如何将html输入框与javascript数据过滤功能相结合，实现一个实时的职位搜索应用。通过利用`document.getelementbyid`获取用户在输入框中键入的值，并将其作为参数传递给javascript函数，我们能够对预定义的工作列表进行动态、大小写不敏感的筛选，最终在控制台输出匹配结果及数量。

构建基础HTML搜索界面

要实现用户交互式的搜索功能，首先需要一个包含输入字段和触发按钮的HTML界面。用户将在此输入他们感兴趣的职位名称和地点。

  
  
  搜索

在这个结构中，我们定义了两个文本输入框，分别用于职位标题和地点，并为它们分配了唯一的id（titleInput和locationInput），以便JavaScript能够准确地获取它们的值。一个按钮被用于触发搜索操作，其onclick事件绑定了一个名为searchJobs()的JavaScript函数。

定义职位数据与搜索逻辑

在前端应用中，数据通常以数组或对象的形式存在。这里我们使用一个包含多个职位对象的数组作为示例数据源。每个职位对象都包含title和location属性。
