我正在使用AdminLTE引导程序模板。 我想在点击它时禁用或关闭附加到侧边栏项目的所有点击事件处理程序（展开/折叠行为）。
这是我到目前为止所尝试的内容，但它只禁用了当前的方法。 注意：“do-not-open”是我分配给所有treeview li项目的特定类。
$(".do-not-open").on("click", function (e) {
alert("Please select fields first");
/// $(this).unbind("click")
$(this).off("click")
return;
})
现在.off（）或.unbind（）只是禁用当前的click方法而不是其他文件中的其他事件处理程序。 这是我的代码的html

使用event.preventDefault API
阻止默认行为$(".do-not-open").on("click", function (e) {
e.preventDefault();
... Your codes here
return;
})
这将阻止重定向。

为什么不这样做？
$(".do-not-open").off('click');
会删除所有匹配的li项的点击次数吗？
