This code could be in javascript, PHP, it doesn't really matter to me. 回答1: This should help you out. Here is a tutorial regarding usage - a demo is found below: Usage: <input name="text" onKeyDown="CountLeft(this.form.text, this.form.left,50);" onKeyUp="CountLeft

问题 In response to an example I posted previously, Andreas Oetjen showed a neat way to display a table of fractional and decimal numbers in textView using attributed strings aligning numbers so the decimal point or forward slash characters appear in the same column as shown in Example 1 below . With that introduction to attributed strings I was prompted to ask: how to display each column in a different colour or font ? ( to associate data with file types found elsewhere in the app ) When I try to

Prevent grep in R from treating “.” as a letter

问题 I have a character vector that contains text similar to the following: text <- c("ABc.def.xYz", "ge", "lmo.qrstu") I would like to remove everything before a . : > "xYz" "ge" "qrstu" However, the grep function seems to be treating . as a letter: pattern <- "([A-Z]|[a-z])+$" grep(pattern, text, value = T) > "ABc.def.xYz" "ge" "lmo.qrstu" The pattern works elsewhere, such as on regexpal. How can I get grep to behave as expected? 回答1: grep is for finding the pattern. It returns the index of the

regex to also match accented characters

问题 I have the following PHP code: $search = "foo bar que"; $search_string = str_replace(" ", "|", $search); $text = "This is my foo text with qué and other accented characters."; $text = preg_replace("/$search_string/i", "<b>$0</b>", $text); echo $text; Obviously, "que" does not match "qué". How can I change that? Is there a way to make preg_replace ignore all accents? The characters that have to match (Spanish): á,Á,é,É,í,Í,ó,Ó,ú,Ú,ñ,Ñ I don't want to replace all accented characters before

How to count grapheme clusters or “perceived” emoji characters in Java

由 只谈情不闲聊 提交于 2019-12-22 05:25:21
问题 I'm looking to count the number of perceived emoji characters in a provided Java string. I'm currently using the emoji4j library, but it doesn't work for grapheme clusters like this one: 👩‍👩‍👦‍👦 Calling EmojiUtil.getLength("👩‍👩‍👦‍👦") returns 4 instead of 1 , and similarly calling EmojiUtil.getLength("👻👩‍👩‍👦‍👦") returns 5 instead of 2 . Are there any APIs or methods on String in Java that make it easy to count grapheme clusters? I've been hunting around but understandably the codePoints()

Breaking down a Hangul syllable into letters (jamo)

由 谁说胖子不能爱 提交于 2019-12-22 01:17:29
问题 I'm working on a program that deals with Korean sentences and I need a way to break down a syllable, or block, into its letters. For those who don't know Hangul, a syllable is composed of 2-4 letters (jamo), creating thousands of different combinations. What I'd like to do is break down those syllables into the letters that form it. I was able to get the first letter by comparing its Unicode value to the associated letter in that range, i.e. a syllable that starts with x letter is in y range.
