google apps script - Googlesheets - javascript - Hide columns after column 21 that do not equal a given cells value -

-

itemprop = "text">

My goal is to hide all the columns in all the Google columns based on the text / value of a cell. Range & amp; With column 22 ("U"), the code will hide all the columns in this category, without any line ROW 1 in "J812" (i.e. 812,10), which is a drop down list Is selected through (via data validation).

I have been introduced to Java Script now, so please bear up on my innovation! Through search online, I have put my own solution together, the only problem is that when a script is completed, it shows an error ... in a red box, "call reference outside context". I do not know how this error has disappeared ... plz help

A part of my code comes from here ""

Here's my code: < / P> 

  Hide function column () {var ss = SpreadsheetApp.getActiveSpreadsheet (); Var letter = ss.getActiveSheet (); // Get the data var data = sheet.getDataRange (); // Get the number of columns lastCol = data.getLastColumn () + 1; Logger.log (lastCol); // Call for call (var i = 1; i & lt; lastCol; i ++) {if.get (1, 21 + i) .getValue ()! == Sheet.Getrenz (812,10) .getValue ()) {Sheet.hideColumns (21 + i); }}}

Any help would be appreciated!

The last call is your last column. 1. For your loop, you loop loop till lastCol, however this is 21 + i in getCell (), which means that you go 21 very far and therefore are out of range: -)

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
