问题 I am a beginner in JavaScript and wanted to ask the following: I have two simple functions and was wondering if there is any way to pass a variable value from one function to another. I know I can just move it outside the function to be used in other functions as well but just need to know the way how I can have one local variable and manipulate with it in my second function. Is this possible and how? Here is some code: window.onload = function show(){ var x = 3; } function trig(){ alert(x);

问题 Overview: I would like my KSH script to test for the presence of certain files in a directory, present the user with a list of those files along with a number. The user then chooses the number they want and the relevant value from the array is assigned to a variable. So far I have the following: ### Create test files in directory #### touch ABCDEF.jar touch BCDEFG.jar touch CDEFGH.jar touch DEFGHI.jar touch EFGHIJ.jar touch FGHIJK.jar touch GHIJKL.jar set -A JARS ` ls -1 | grep .jar | cut -d'

问题 I would like to hide certain columns and rows based on inputs into certain cells, to make the code easily editable. Furthermore, if the reference cell/range is empty, then I would like to continue the code without hiding any rows or columns. Columns to Hide: based on cells C8:D8 Rows to Hide: based on cells C9:D9 This is where the logical fest should take place reportColumnsAddr = settingsSheet.Range("C8").Value & ":" & settingsSheet.Range("D8").Value reportRowsAddr = settingsSheet.Range("C9"

问题 I have a number of related questions about tensorflow behavior when attempting to do graph surgery using import_graph_def . 2 different graph surgeries In the image above, I represent with bold red arrows 2 different graph surgeries. On the left, there are 2 graphs, g1 and g2, and the surgery consists of replacing a node in graph g2 by a node - and everything below it - from graph g1. How to do that is explained in this post. The surgery on the right, which involves replacing nodes that

问题 Are there any "general rules" as to when one is preferable to the other? The context of this question is: I asked a different question regarding host association yesterday (link) and in the comments, I was advised to use host association with caution. The reason being that through host association, it is easy to inadvertently modify variables since the subroutines have unrestricted access to all variables that are declared in the module. To illustrate this, I will use the following code
