Hi. Textarea introduces poems. How do we identify the entry numbers of all wire transfers on Javascript?

var txt = document.getElementById('txtarea').value.replace('\r', '');
var txtar = txt.split('\n');
//а далее - работаем с txtar[i].length

IE7 (thanks AlexWindHope):

var txt = document.getElementById('txtarea').value.replace('\r', '');
var txtar = txt.split('\n');

//а далее - работаем с (txtar[i].indexOf('\r') ? txtar[i].length-1 : txtar[i].length)

Based on the logic that we have to start the violin after the addition of the block, it was added in .append()"<script src='https://yastatic.net/share2/share.js' async='async'></script>"It's working.There is no need for "var share = Ya.share2."But I think it's kind of weird.Smart advice, huh?

I am not very clear if you find www.ejemplo.com/archivo, you want to replace all that piece, including the domain name, or only "/archivo".I'm going to present a possible solution based on the first assumption. Anything you tell me:<?php // Para la prueba $url_image = 'https://www.ejemplo.com/archivo'; $image = 'www.foo.com/bar'; // Script $variable='www.ejemplo.com/archivo'; $url_search='#^(https?://)'.preg_quote($variable, '#').'#i'; $result=preg_replace($url_search, '$1'.$image, $url_image); print $result . "\n"; Changes made:The most important thing, when incorporating the variable in the regular expression, escape it with preg_quote, as the variable can contain special characters with meaning for a regular expression (such as the point . for example)I have simplified a bit the capture of http/s by making the optional 's' (?)I have changed the delimiters of the regular expression to #, so I don't have to escape the bars and it's more legible.By assigning the value to $variable you have to encapsulate the string with quotes and finish the instruction with ;In str_replace you had the second and third parameter rotated. The second is the expression of replacement and the third is the string where to perform the substitutions.

I don't understand your question, because it's not clear enough. But to catch the domain you can use a Javascript property that returns the domain of the page.document.domain When running this on the console of the so you will have the following return:"pt.stackoverflow.com" For more information you can access this documentation by clicking https://developer.mozilla.org/en-US/docs/Web/API/Document/domain .

No, your system doesn't need to have an injection vulnerability. While you could implement these clauses easily (and insecurely) by doing an "eval", or tossing the result in a WHERE with no validation, it is possible to do that properly. You would parse the to verify it conforms to the proper format, and then build back a now-trusted query.

https://datatables.net/examples/basic_init/table_sorting.html , it is possible to change the ordering of a DataTable using the property order which is a vector of two-position vectors, where the first indicates which column (from 0) and the second type, whether it is growing (asc) or descending (desc), as following example:$(document).ready(function() { $('#example').DataTable( { "order": [[ 3, "desc" ]] //Ordena pela quarta coluna de forma descrescente } ); } );

It can be achieved with recursive expressions, unfortunately they are not supported in javascript.To do so in javascript you would have to specify it manually in the expression, but it will always be limited to the number of inner brackets you consider when creating the expression, up to 2 inner brackets could be:let regExp = /F[(?:[^[\]]+|[(?:[^[\]]+|\[[^[\]]*])*])*]/g; https://regex101.com/r/uDI3Ez/5 Or you can use the library. https://github.com/slevithan/xregexp , although you would have to add the delimiters again if you need them as it eliminates them.let matches = XRegExp.matchRecursive(txt, 'F\[', '\]', 'g'); let newmatches = matches.map(match => 'F[' + match + ']'); In case you're interested in pcre with recursive expression it might be:/(F*)[(?>[^[\]]+|(?R))*]/g https://regex101.com/r/E7mVe9/5

Since only one coincidence is expected in each line, you will have the following expression:(?s)^\s*{\s*(\w+)\s*\?\s*(.*?)(?:\s*:\s*({[^{}]*}|\S+))?\s*}\s*$ See. https://regex101.com/r/xFjtfe/2 ♪Details(?s) - a flag allowing the point to also locate the ports of the line^ - beginning of text\s*{\s* - symbol {on the left and on the right of which there may be 0 and more underweight symbols(\w+) - Group No. 1: one and more letters, numbers or symbols of the bottom line\s*\?\s* - symbol ?on the left and on the right of which there may be 0 and more underweight symbols(.*?)

Yes, these are comments for regular C# expressions (or more specifically .NET, since it is valid for all languages that adopt .NET as a library). Everything that is after # until the dim of the line will be ignored. It is also possible to determine the beginning and end of the comment with parentheses.In other languages or more specifically in other regular expression libraries comments may be available with a slightly different syntax. https://docs.microsoft.com/en-us/dotnet/standard/base-types/regular-expression-language-quick-reference?WT.mc_id=DOP-MVP-5002397#miscellaneous_constructs .

If you have a class last One element on the page will work. If you have several tables on the page and each table has a line with the class. lastThen, when selecting the seltzer, describe the search context$('.last', table).before(newTr);
