Disable iPython Notebook Autoscrolling
提问by Nyxynyx
In iPython Notebook, is it possible to disable the autoscrolling of long outputs? Or at least set a threshold for the output length before autoscrolling sets in?
在 iPython Notebook 中，是否可以禁用长输出的自动滚动？或者至少在自动滚动设置之前为输出长度设置一个阈值？
Tried the following command
尝试了以下命令
%%javascript
IPython.OutputArea.auto_scroll_threshold = 9999;
but it gives an error
但它给出了一个错误
Javascript error adding output!
SyntaxError: Unexpected identifier
See your browser Javascript console for more details.

To disable auto-scrolling, execute this javascript in a notebook cell before other cells are executed:
要禁用自动滚动，请在执行其他单元格之前在笔记本单元格中执行此 javascript：
%%javascript
IPython.OutputArea.prototype._should_scroll = function(lines) {
return false;
}
There is also an ipython notebook extension, disable_autoscroll, you can use for a more permanent change. Follow ipython issue #2172for the latest details.
还有一个 ipython 笔记本扩展，disable_autoscroll，您可以用于更永久的更改。关注ipython issue #2172了解最新详情。

Can also be done via user interface.
也可以通过用户界面完成。
- Individual cells: Cell->Current Outputs->Toggle Scrolling
- All cells: Cell->All Outputs->Toggle Scrolling
- 单个单元格：单元格->当前输出->切换滚动
- 所有单元格：单元格->所有输出->切换滚动

This works for me (with no semicolon)
这对我有用（没有分号）
%%javascript
IPython.OutputArea.auto_scroll_threshold = 9999
回答by Oldrich Svec
To disable scroll to bottom after run allcommand, execute this code:
要在run all命令后禁用滚动到底部，请执行以下代码：
%%javascript
require("notebook/js/notebook").Notebook.prototype.scroll_to_bottom = function () {}

In the similar way that you can hack a cell to autorun, you can add the following cell:
以类似的方式，您可以将单元格修改为 autorun，您可以添加以下单元格：
%%javascript
require(
["notebook/js/outputarea"],
function (oa) {
oa.OutputArea.auto_scroll_threshold = -1;
console.log("Setting auto_scroll_threshold to -1");
});
which will set the auto_scroll_thresholdto -1which means never autoscroll.
这将设置auto_scroll_threshold为-1这意味着从不自动滚动。
This works on my notebooks that are trusted (e.g. jupyter trust notebook.ipynb), not sure if anycells are executed in untrusted notebooks.
这适用于我受信任的笔记本（例如jupyter trust notebook.ipynb），不确定是否在不受信任的笔记本中执行了任何单元格。
