Question

我正在使用搜索框，我尝试了多个修复程序，所有修复都反映在代码中。当您单击搜索按钮时，搜索栏将工作并转到搜索页面，但是如果您按下回车键，它只会将当前页面的刷新版本拉入新选项卡。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，并且在您按Enter键时默认提交表单。通过处理onsubmit函数覆盖表单的默认提交行为。如果您从此函数返回false，则表单将不会提交。

<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。只需删除表单标记，您就不需要它，因为您有java脚本来处理搜索。这将解决问题。
