为什么我的 HTML 控件没有响应？

Question

我正在尝试让 sigma.js 原型正常工作。基本上，当您单击 dragnode 按钮时，它应该执行 javascript 以添加所有 sigma 功能。

当前，此页面正在加载，但 none 的控件有响应（单击文本框内的单击光标，无法按下按钮）。

在控制台中调试没有发现任何错误。

导入sigma.js模块禁用控件可能很简单吗？

Answer 1

图形容器 div 与您的控件重叠。

更改 div 在样式 sheet 中的定位以修复。 \

<style>
#graph-container {
    top: 100px;
    bottom: 200px;
    left: 0;
    right: 100px;
    background-color: #d3d3d3;
    position: absolute;
}

#sidebar {
    bottom: 0;
    right: 0;
    width: 200px;
    height: 150px;
    position: absolute;
    background-color: #999;
    padding: 10px;
}
</style>

（为清楚起见，切换为浅灰色）。
