访问Chrome控制台中的上次记录的值

Question

直接在Chrome控制台中评估表达式时

1 + 1

然后我可以使用

引用评估值

$_

但是，当值是来自应用程序内部的console.log的结果，而不是直接输入控制台的表达式时，我无法使用$ _访问该值。

有没有办法访问最后评估的表达式，无论它来自何处？

Answer 1

在它登录到控制台后，您可以右键单击它并获得存储为全局功能的选项。点击此按钮将定义一个新变量，例如＆＃39; temp1＆＃39;这将指向变量。 Here's a video of it in action (not mine)

Answer 2

请按以下步骤操作：

1. 使用右键单击结果
2. 另存为全局变量
3. 拷贝（temp1中）

Answer 3

你只能复制＆amp;糊。

Answer 4

解决此问题的方法是在全局命名空间中定义变量。据推测，您的console.log(local_variable)位于函数内部。

<script>
  var global_variable = null;

  function some_function() {
    var local_variable = 0;
    global_variable = local_variable;
    console.log(local_variable);
  }
</script>

此处，当调用some_function()时，系统会记录您的local_variable，但您可以在控制台中输入global_variable以快速获取其值并使用它。

Answer 5

您可以通过设置断点，在Chrome的DevTools执行的任何时候访问任何已评估的表达式。

您记录的表达式应该在控制台中有一个可点击的行号 - 按照链接，然后在代码行（应该是您的org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: Scripts not permitted to use new java.util.LinkedHashMap at

我认为function ReFormatTime() { return moment().format("YYYY-MM-DDT00:00:00"); } var now = ReFormatTime(); var _url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('Bokningar')/items?$select=EndDate%2CID%2CEventDate%2CLinkTitle%2CIsBlock%2CProgram_x0020_Id&$filter=EventDate ge datetime'" + now + "'&$top=5000"; 正是您所寻找的。
