如何通过Javascript在Popover (Bootstap)中添加Html标记(如<button>)

Question

我用的是Bootstrap。我想在弹出框里有个按钮。以前很好，但现在不行了。

<button type="button" class="btn btn-primary mx-2" id="pop" data-container="body" data-toggle="popover" data-placement="bottom" data-html="true" data-content="">
  Button
</button>

Javascript：

function updatePopover() {
    var popStr = "";
    popStr = popStr + "<h5> Heading :  </h5><div class='mx-2 my-2'>";
    popStr = popStr + "<button class='btn btn-success' onclick='function()' id ='funcid'>Button</button>"
    document.getElementById('pop').setAttribute('data-content', popStr);
    $('#popcart').popover('hide');

}

Answer 1

简单地说，您可以执行以下操作：

​

var dynamicData = ['Dynamic Data', 'Dynamic Data', 'Dynamic Data', 'Dynamic Data'];

$('[data-toggle="popover"]').popover({
    title: "<h5>Heading</h5>",
    content: function () {
        var resultData = $(`<div><ul class="list-group">`);
        for (var i in dynamicData) {
            resultData = resultData.add(
                `<li class="list-group-item d-flex justify-content-between align-items-center">
                    `+ dynamicData[i] + `
                    <span class="badge badge-primary badge-pill">`+ i + `</span>
                </li>`
            );
            // console.log(i, dynamicData[i]);
        }

        resultData = resultData.add(`</ul><br/><button class='btn btn-danger' id ='funcid'>Close</button></div>`);

        return resultData;
    }
});

$(document).on("click", "#funcid", function () {
    $(this).parents(".popover").popover('hide');
});

.popover-body {
    width: 200px;
}

你提供的代码被破坏了。你把"忘在了

popStr = popStr + "<button class='btn btn-success' onclick='function()' id ='funcid'>Button</button>"

你能试试吗，看看它是否解决了你的问题。
