Javascript在新标签中输入密钥打开页面

Question

我正在使用搜索框，并且尝试了多个修复程序，所有这些都反映在代码中。当您单击搜索按钮时，搜索栏会工作并将您带到搜索页面，但是如果您按下回车键，它只会将当前页面的刷新版本拉到新选项卡中。有人知道解决这个问题的方法吗？

Answer 1

您的文本框位于表单内，当您按回车键时默认提交表单。通过处理 onsubmit 函数来覆盖表单的默认提交行为。如果您在此函数中 return false，表单将不会提交。

<form target="_blank" onsubmit='return handleSubmit();'>
    <div><input type="text" placeholder="Search Google" onchange="urlinput(event)" onkeypress="return searchit()"></div>
    <br />
    <a id="searchbutton" href="" onclick="searchit()" target="_blank" onkeypress="return searchit()">Search</a>
</form>


<script>
  function handleSubmit() {
    return false;
  }
</script>

Answer 2

这是一个简单的修复。只需删除表单标签，您不需要它，因为您有 java 脚本来处理搜索。这将解决问题。
