function removeLeadingZeros(str) { // 实现去除字符串前面0的逻辑 } 2. 在函数内部,使用正则表达式或循环结构识别并去除字符串前面的0 这里我们使用正则表达式来实现,因为它既简洁又高效: javascript function removeLeadingZeros(str) { // 使用正则表达式匹配并去除字符串前面的0 return str.replace(/^0+/,...
function removeLeadingZeros(str) { let i = 0; while (i < str.length && str[i] === '0') { i++; } return i === str.length ? '0' : str.substring(i); } // 示例 console.log(removeLeadingZeros("000123")); // 输出: "123" console.log(removeLeadingZeros("0000")); // 输...
function removeLeadingZeros(dateStr) { return dateStr.replace(/-(0)(\d)/g, '-$2'); } const dateWithZeros = "2023-04-09"; const dateWithoutZeros = removeLeadingZeros(dateWithZeros); console.log(dateWithoutZeros); // 输出: "2023-4-9" 方法二:使用Date对象解析和格式化 代码语言:txt 复...
// Increment result exponent if there is a final carry, otherwise remove leading zero. if (b) ++y.e; else c.shift();// Remove trailing zeros. for (i = c.length; !c[--i];) c.pop(); y.c = c;return y; };/* * Return a string representing the value of this Big in ...
