Text is no copying by clipboard.js – Jquery

I’m trying to copy text using clipboard.js but it’s not copying.
here’s my code

$(document).ready(async function () {
    var html = ''
    var script = '<script>'
    let response = await ajax('/admin/all_files', 'POST', '')
    for (let i = 0; i < response.length; i++) {
        var url = window.location.origin + '/get_file/' + response[i][0]
        html += `<div>
                <img src="`+ url +`" alt="">
                <div>
                    <button  id="ttc_`+ i +`_url" data-clipboard-text=`+ url +`>URL</button>
                </div>
            </div>`
        script += `var ttc_`+ i +`_url = new Clipboard('#ttc_`+ i +`_url');`
    }
    $('#insert_image_modal_body').html(html)
    script += '</script>'
    $('body').append(script)
})

my ajax function is:

async function ajax(url, method, data) {
    return $.ajax({
        url: window.location.origin + url,
        method: method,
        data: data
    }).done((response) => {
        return response
    });
}

it shows nothing, no error but the text is not copying too.

    I think the error is due to bootstrap modals, I was adding data to the modal. Adding data to a single div outside the modal and using the append function instead of HTML solved my problem.

    Now my code is

    let html = '';
    const response = await ajax('/admin/all_files', 'POST', '');
    for (let i = 0; i < response.length; i++) {
        const url = window.location.origin + '/get_file/' + response[i][0];
        html += `
            <div style="border-radius: 9px; border: 1px solid #000; height: 150px;" class="col-1 col m-1 p-1 d-flex flex-column align-items-center">
                <img style="height: 100px; width: auto; max-width:100%" src='${url}' alt="" />
                <div class="row m-0 my-1 p-0 justify-content-center">
                    <button style="width: 45%;" class="mx-1 btn btn-sm btn-outline-success clipboard" data-clipboard-action='copy' data-clipboard-text='${url}'>URL</button>
                    <button style="width: 37%;" class="mx-1 btn btn-sm btn-outline-primary clipboard" data-clipboard-text='Hi 2'>Alt</button>
                </div>
            </div>`;
    }
    $('#insert_image_box_body').append(html);

    Couple of things, I noticed in some areas you were using var when you could’ve been using let or const (as of ES6). Here’s a good article that will describe the differences for you: https://www.freecodecamp.org/news/var-let-and-const-whats-the-difference/

    Secondly, your code seems to generate javascript, within javascript… it’s possible what you’re doing, but might as well just do what you’re doing within the existing script tags that you already have.

    Thirdly, you are attempting to use template literals to form you strings. That’s great, however you aren’t leveraging the most important part, and that’s the ability to inject values directly into the string using the ${} notation.

    Regarding the clipboard code. Since you are utilizing data-clipboard-text there’s no need to require each button to have a unique id. Instead you can add a class, for example copy-btn that you add to each button. This way you only have to call new ClipboardJS('.copy-btn'); once!

    Taking all of these into consideration, I’ve cleaned up your code a bit below:

    $(document).ready(async function () {
        let html = '';
        const response = await ajax('/admin/all_files', 'POST', '');
        for (let i = 0; i < response.length; i++) {
            const url = window.location.origin + '/get_file/' + response[i][0];
            html += `
                <div>
                    <img src='${url}' />
                    <div>
                        <button class='copy-btn' data-clipboard-text='${url}'>URL</button>
                    </div>
                </div>
            `;
        }
        $('#insert_image_modal_body').html(html);
        new ClipboardJS('.copy-btn');
});
