用于匹配以数字结尾的常量单词的正则表达式是什么

Question

我要匹配的字符串就像 -

'RANDOM1', 'RANDOM2', 'RANDOM78'

此处 RANDOM 一词始终以数字结尾。 任何帮助，将不胜感激。

Answer 1

您需要从该行的开头（private void ProcessContent() { for (int page= 1; page <= pdfReader.NumberOfPages; page++) { var strategy = new LocationTextExtractionPersonalizada(); var currentPageText = PdfTextExtractor.GetTextFromPage( pdfReader, page, strategy); //Here is where I want to get each word with its coordinates var chunksWords= ChunkRawToWord(strategy.ChunksInPage); } } private List<Chunk> ChunkRawToWord(IList<Chunk> chunks) { if (chunks == null || chunks[0] == null) return null; var words = new List<Chunk>(); //Poor RegEx pattern to get the word and its wathever string pattern = @"[@&\w+]*(-*\/*\s*\:*\;*\,*\.*\(*\)*\%*\>*\<*)?"; var something = chunks[0].Render.GetCharacterRenderInfos(); for (int i = 0; i < chunks.Count; i++) { var wordsInChunk = Regex.Matches( chunks[i].Text, pattern, RegexOptions.IgnoreCase); var rectangleChunk = new Rectangle(chunks[i].Rect); for (int j = 0; j < wordsInChunk.Count; j++) { if (string.IsNullOrWhiteSpace(wordsInChunk[j].Value)) continue; var word = new Chunk( rectangleChunk, chunks[i].Render, wordsInChunk[j].ToString()); if (j == 0) { word.Rect.Right = word.BF.GetWidthPoint(word.Text, word.FontSize); words.Add(word); continue; } if (words.Count <= 0) continue; word.Rect.Left = words[j - 1].Rect.Right; word.Rect.Right = words[j - 1].Rect.Right + word.BF.GetWidthPoint(word.Text, word.FontSize); words.Add(word); } } return words; } ）和之后的一个或多个字符（^）匹配单词RANDOM

你可以试试这个：

var str='RANDOM1';
if(/^RANDOM\d+$/gi.test(str))
  console.log('true');
else
  console.log('false');
