After clicking to submit the form in Empire CMS, use js to combine the URL and redirect it

Often, search engine-generated links are excessively long and contain numerous query parameters; we therefore wish to implement pseudo-static URL rewriting while ensuring these links remain accessible for subsequent visits. Original HTML code:

<form class="form-search" id="q-form" method="get">
                <div class="input-append" id="q-input">
                    <input type="text" class="span6 search-query" name="q" title="输入任意关键词皆可搜索"
                           value="">
                    <button type="submit" class="btn">搜索</button>
                </div>
            </form>

<form class="form-search" id="q-form" method="get">
  <div class="input-append" id="q-input">
    <input type="text" class="span6 search-query" name="q" title="输入任意关键词皆可搜索"
           value="" onkeypress="return handleKeyPress(event)">
    <button type="button" class="btn" onclick="submitForm()">搜索</button>
  </div>
</form>

<script>
function handleKeyPress(event) {
  if (event.keyCode === 13) { // 13是回车键的键码
    event.preventDefault(); // 阻止默认行为
    submitForm(); // 调用submitForm()方法处理表单提交
  }
}

function submitForm() {
  // 获取输入框的值
  var query = document.getElementById("q-input").querySelector("input[name='q']").value;
  
  // 组合URL
  var url = "/moreSearch/" + encodeURIComponent(query) + ".html";
  
  // 重定向到URL
  window.location.href = url;
}
</script>
