javascript - How to detect rendered new lines in text node -

-

O people

First of all, I need to know a text node that when / where a text will wrap in the second row.

I think textNode, iterate over the letter by letter, create a new TextNode compound of all the letters till the current step, after that I calculate the height of the text node, if the height of the current step is past If one is different from the other, wrapped the row.

The problem is that I have a hard time understanding the height of the existing text. This is what I have done so far:

You can see that getTextNodeHeight height is wrong and I do not know what is wrong. I got this function.

How do any of you solve this problem? Or is there a better way for this problem?

Set a coordinate somewhere in the middle of your text. Call offset the relative left side of this position at a fixed time interval measured by SetTimeout. Start an event listener on page load, which considers the left offset negative (meaning it is now for the rights of this situation), the event listener starts only one other event listener, which is positive for the left offset , Which will be a symbol. \ N Call two events back and forth to the audience. If you have any questions then I will be back in a few hours.

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job.
