Javascript/jQuery - replace last occurence of a word in a string
提问by ojek
I have a string that ends with a fixed word - Button. Now I need to replace that word with ''. How can I do it? Also, if my string is something like ButtonButtonor similar, I need to cut out only last Button.

var original = 'ButtonButton';
var newString = original.replace(/Button$/, '');
// "Button"

If you don't have to check, if it really ends with Button, just remove the last 6 letters:
如果您不必检查，如果它真的以 结尾Button，只需删除最后 6 个字母：
var str = "ButtonButton";
str = str.substr(0,str.length-6);
console.log(str); //"Button"
