使用生成的链接URL填充文本字段

我创建了一个简单的表单,允许用户上传图像并提交表单。表单数据上传到Google电子表格。为了在谷歌电子表格中填充图像,我需要图像拥有自己的网址。我正在测试imgur的API,并且在完成此操作之后它非常有效:https://hacks.mozilla.org/2011/03/the-shortest-image-uploader-ever/

现在我的表单为该特定图片生成了一个网址,如何使用该网址填充我的Google电子表格?我正在考虑使用一个文本框,它会在生成时自动填充href,但我不知道该怎么做。

在imgur的API生成链接后,是否有更简单的方法将链接粘贴到我的电子表格中?

我在这里包含了它的工作演示。



 function upload(file) {
        /* Is the file an image? */
        if (!file || !file.type.match(/image.*/)) return;
        /* It is! */
        document.body.className = "uploading";
        /* Lets build a FormData object*/
        var fd = new FormData(); 
        fd.append("image", file); // Append the file
        var xhr = new XMLHttpRequest(); // Create the XHR
        xhr.open("POST", "https://api.imgur.com/3/image.json"); // Boooom!
        xhr.onload = function() {
            // Big win!
            document.querySelector("#link").href = JSON.parse(xhr.responseText).data.link;
            document.body.className = "uploaded";
        }
        
        xhr.setRequestHeader('Authorization', 'Client-ID 490be95195679b1'); // Imgur API key here
        
       
        /* And now, we send the formdata */
        xhr.send(fd);
    }

#link, p , div {display: none}
    .uploading div {display: none}
    .uploaded div {display: none}
    .uploading p {display: inline}
    .uploaded #link {display: inline}

<input type="file" onchange="upload(this.files[0])"><br />
<!-- this is the text box we could paste the url in -->
<input tyle="text">

<p>Uploading...</p>
<a id="link">Link to imgur file</a>

这将使用网址填充文本框

document.getElementById("urlText").value = JSON.parse(xhr.responseText).data.link;

<input type="text" id="urlText" name="urlText">

        /* It is! */
        document.body.className = "uploading";
        /* Lets build a FormData object*/
        var fd = new FormData(); 
        fd.append("image", file); // Append the file
        var xhr = new XMLHttpRequest(); // Create the XHR
        xhr.open("POST", "https://api.imgur.com/3/image.json"); // Boooom!
        xhr.onload = function() {

            document.querySelector("#link").href = JSON.parse(xhr.responseText).data.link;
            document.body.className = "uploaded";
       document.getElementById("urlText").value = JSON.parse(xhr.responseText).data.link;

        xhr.setRequestHeader('Authorization', 'Client-ID 490be95195679b1'); // Imgur API key here
        

        /* And now, we send the formdata */
        xhr.send(fd);
    }

#link, p , div {display: none}
    .uploading div {display: none}
    .uploaded div {display: none}
    .uploading p {display: inline}
    .uploaded #link {display: inline}

<input type="file" onchange="upload(this.files[0])"><br />
<input type="text" id="urlText" name="urlText">

<p>Uploading...</p>
