无法获得引导工具提示来显示在 JS 中创建的图像

Question

I am trying to display a barcode image that is generated via JsBarcode inside a bootstrap tooltip.

What I have tried:

1. I tried to move around the Tooltip js code in front and behind the JsBarcode js code.

2. I have searched for anything similar online but the only thing that somewhat resembles a solution is to trigger the JsBarcode code on a btn click and the bootstrap tooltip on page load. This doesn't work for me. I was looking for both to be initialized on page load so that the tooltip would work.

HTML:

    <a id="SellerSKU_ToolTip" data-toggle="tooltip" data-html="true" data-placement="bottom" class="White-tooltip" title="<svg id='Barcode_Seller_SKU'></svg>">123456789012</a></td>

JS Code:

   $(document).ready(function () {

    $(function () {
        $('[data-toggle="tooltip"]').tooltip()
    })

    JsBarcode("#Barcode_Seller_SKU", "1234", {
        format: "auto",
        lineColor: "#0aa",
        width: 2,
        height: 25,
        displayValue: true
    });
    }

The error:

JsBarcode.all.min.js:3 Uncaught TypeError: r.options(...)[n.format] is not a function
    at j (JsBarcode.all.min.js:3)
    at HTMLDocument.eval (eval at globalEval (jquery.min.js:2), <anonymous>:11:9)
    at j (jquery.min.js:2)

    at n.fn.init.append (jquery.min.js:3)
j @ JsBarcode.all.min.js:3

I would be grateful for any help or advice.

Answer 1

The error here is because your code:

JsBarcode("#Barcode_Seller_SKU", "1234", {

is expecting the SVG element to be present on document ready.

But since the tooltip content is generated dynamically on-hover of the element, the SVG element you're expecting to make into a barcode would only be available after you hover over the anchor element.

You can use Bootstrap's tooltip on-show event to create your barcode. Something like this:

 $(function() { var tt = $('[data-toggle="tooltip"]').tooltip({ placement: "right" }); tt.on("shown.bs.tooltip", function() { JsBarcode("#Barcode_Seller_SKU", "123456789012", { format: "EAN13", lineColor: "#0aa", width: 2, height: 25, displayValue: true }); }); });

 .tooltip-inner { max-width: none;important; }
