如何使用Javascript查找index.html文件存储在目录中的目录？

Question

我正在使用输入框，当按下搜索按钮时，我想查看搜索到的术语是否是index.html文件存储在其中的目录中的现有目录。这是迄今为止的代码：

function searchWebs () {
    var searchedTermRaw = document.getElementById('searchBox').value;
    var searchedTerm    = searchedTermRaw.toUpperCase();
    if (searchedTerm == "") {
        return;
    } else {
        if (searchedTerm == "NUMI" || searchedTerm == "ELMDON PM") {
            document.getElementById('searchFor').innerHTML        = "Search results for '" + searchedTermRaw + "'.";
            document.getElementById('searchForDetails').innerHTML = "";
        } else {
            document.getElementById('searchFor').innerHTML        = "No search results were found for '" + searchedTermRaw + "'.";
            document.getElementById('searchForDetails').innerHTML = "Please use the ID provided within the email Netwal sent you, if you have not been sent an email with the ID, your website isn't ready for viewing/testing yet.";
        }
    }
}

<div class="section">
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <div class="col-sm-12">
                    <input type="text" class="form-control input-lg" id="searchBox" placeholder="Website ID">
                </div>
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <br>
                    <a class="btn btn-lg btn-primary col-lg-12" onclick="searchWebs();">Search</a>
            </div>
        </div>
    </div>
</div>
<div class="section">
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <h1 id="searchFor"></h1>
                <p id="searchForDetails"></p>
            </div>
        </div>
    </div>
</div>

我想替换if语句以检查搜索项是NUMI还是ELMDON PM，并检查目录是否存在。

使用此方法searchedTerm并传递路径或https://stacksnippets.net/

确保维护跨域政策。

我已为此问题添加了baseUrl var baseUrl = "https://stacksnippets.net/"; function isAvailable(url) { url = baseUrl + url; var http = new XMLHttpRequest(); http.open('HEAD', url, false); try { http.send(); } catch (err) { return false; } return http.status != 404; } 。

js

示例：

我尝试了baseUrl一词，这会生成网址https://stacksnippets.net/js

  

我担心这个例子由于跨域错误和混合内容错误而无法正常工作，但这种方法适用于您的情况。

您可以通过更改function searchWebs() { var searchedTermRaw = document.getElementById('searchBox').value; var searchedTerm = searchedTermRaw.toUpperCase(); if (searchedTerm == "") { return; } else { if (isAvailable(searchedTerm)) { document.getElementById('searchFor').innerHTML = "Search results for '" + searchedTermRaw + "'."; document.getElementById('searchForDetails').innerHTML = ""; } else { document.getElementById('searchFor').innerHTML = "No search results were found for '" + searchedTermRaw + "'."; document.getElementById('searchForDetails').innerHTML = "Please use the ID provided within the email Netwal sent you, if you have not been sent an email with the ID, your website isn't ready for viewing/testing yet."; } } } var baseUrl = "https://stacksnippets.net/"; function isAvailable(url) { url = baseUrl + url; var http = new XMLHttpRequest(); http.open('HEAD', url, false); try { http.send(); } catch (err) { return false; } return http.status != 404; }
