Remove trailing character(s) from string in Javascript
提问by Chris Dutrow
What is an acceptable way to remove a particular trailing character from a string?
从字符串中删除特定尾随字符的可接受方法是什么？
For example if I had a string:
例如，如果我有一个字符串：
> "item,"
And I wanted to remove trailing ','s only if they were ','s?
我想删除尾随的 ',' 仅当它们是 ','s 时？
Thanks!
谢谢！

Use a simple regular expression:
使用一个简单的正则表达式：
var s = "item,";
s = s.replace(/,+$/, "");

if(myStr.charAt( myStr.length-1 ) == ",") {
myStr = myStr.slice(0, -1)
}

A function to trim any trailing characters would be:
修剪任何尾随字符的函数是：
function trimTrailingChars(s, charToTrim) {
var regExp = new RegExp(charToTrim + "+$");
var result = s.replace(regExp, "");
return result;
}
function test(input, charToTrim) {
var output = trimTrailingChars(input, charToTrim);
console.log('input:\n' + input);
console.log('output:\n' + output);
console.log('\n');
}
test('test////', '/');
test('///te/st//', '/');
