Question

我正在创建一个画布绘图应用程序，我希望能够在单击该工具时为每个工具加载光标图像。我做了这个工作，直到我做了一点重新装修并改变了布局。我把工具放在一张桌子里重新设计，但我不认为这应该是问题所在。谢谢你的帮助。

首先删除班级<div class="tools">

中的数字“2”

第二条路径错误，更正：

 $('.tools table tr th div').each(function() {
        $(this).click(function () {
        console.log($(this).attr('id'));
            setCursor($(this).attr('id'));
        });
    });
