Javascript字符串替换为动态创建的模式。

My code only replaces the first match, ignoring the flags (global and multi line). What am I doing wrong?

我的代码只替换了第一个匹配，忽略了标记(全局和多行)。我做错了什么?

for (var i = 0; i < values.length; i++) {
        template = template.replace('{' + i + '}', values[i].toString().trim(), 'gm');
    }

As you can see, my placeholders have this format: {0}, {1} etc

如您所见，我的占位符有这种格式:{0}, {1}等等。

According to MDN, the flags are non-standard for the normal .replace() method. Instead, you can pass in a RegExp with the same result.

根据MDN，旗帜是正常的非标准的。replace()方法。相反，您可以在RegExp中传递相同的结果。

template.replace(new RegExp('\\{' + i + '\\}', 'gm'),
    values[i].toString().trim());

Since curly braces have special significance in regular expressions, you have to escape them.

由于花括号在正则表达式中具有特殊的意义，所以必须要避免它们。
