trim

问题 I know of the jQuery $.trim() function, but what I need is a way to trim whitespace from the END of a string only, and NOT the beginning too. So str =" this is a string "; would become str =" this is a string"; Any suggestions? Thanks! 回答1: You can use a regex: str = str.replace(/\s*$/,""); It says replace all whitespace at the end of the string with an empty string. Breakdown: \s* : Any number of spaces $ : The end of the string More on regular expressions: https://developer.mozilla.org/en

问题 today I was wondering if there is a better solution perform the following code sample. string keyword = " abc, foo , bar"; string match = "foo"; string[] split= keyword.Split(new char[] { ',', ';' }, StringSplitOptions.RemoveEmptyEntries); foreach(string s in split) { if(s.Trim() == match){// asjdklasd; break;} } Is there a way to perform trim() without manually iterating through each item? I'm looking for something like 'split by the following chars and automatically trim each result'. Ah,

问题 This question already has answers here : How can I convert a string to boolean in JavaScript? (83 answers) Closed 2 years ago . JavaScript has parseInt() and parseFloat() , but there's no parseBool or parseBoolean method in the global scope, as far as I'm aware. I need a method that takes strings with values like "true" or "false" and returns a JavaScript Boolean . Here's my implementation: function parseBool(value) { return (typeof value === "undefined") ? false : // trim using jQuery.trim()

This is what I did so far: @ECHO OFF cd /filePath
