jsPlumb 和 Bootstrap 网格

Question

为什么 jsPlumb 不能与 Bootstrap 网格一起使用？我试图让 jsPlumb 在使用 Bootstrap 网格的 HTML 页面上的小部件之间绘制箭头。

我在下面包含的代码呈现出一些完全出乎意料的情况。我正在使用 Firefox 对此进行测试。

            width:80%; height: 400px;
            border: 1px solid gray;
        }

        .item {
            /*height:80px; */
            width: 80px;
            border: 1px solid blue;
            /*float: left;*/

    <script src="//cdnjs.cloudflare.com/ajax/libs/jsPlumb/1.4.1/jquery.jsPlumb-1.4.1-all-min.js"></script>

    <script>
        jsPlumb.ready(function() {
            var common = {
                connector: ["Flowchart"],
                anchor: ["Left", "Right"],
                endpoint:"Dot"
            };

            jsPlumb.connect({
                source:"A",
                target:"B"
            }, common);
            jsPlumb.connect({
                source:"A",
                target:"C"
            }, common);
        });
    </script> 

</body>
</html>

如果我将 div：A、B 和 C 移动到一个 table 中，那么它看起来是正确的。

您正在混合 jQuery 库（3.2.1 和 1.9.1）并且您使用的是旧版本的 jsplumb。

jsPlumb.ready(function() {
    var common = {
        connector: ["Flowchart"],
        anchor: ["Left", "Right"],
        endpoint:"Dot"
    };

    jsPlumb.connect({
        source:"A",
        target:"B"
    }, common);
    jsPlumb.connect({
        source:"A",
        target:"C"
    }, common);
});

#diagramContainer {
    padding: 20px;
    width:80%; height: 400px;
    border: 1px solid gray;
}

.item {
    /*height:80px; */
    width: 80px;
    border: 1px solid blue;
    /*float: left;*/
    margin:50px;
}
