要删除前导零,请replace()
按照以下语法在方法中使用Regex-
yourStringValue.replace(/\D|^0+/g, ""))
假设以下是我们具有数字值的变量-
var theValue1="5001000"; var theValue2="100000005"; var theValue3="05000001"; var theValue4="00000000006456";
var theValue1="5001000"; var theValue2="100000005"; var theValue3="05000001"; var theValue4="00000000006456"; console.log(theValue1.replace(/\D|^0+/g, "")); console.log(theValue2.replace(/\D|^0+/g, "")); console.log(theValue3.replace(/\D|^0+/g, "")); console.log(theValue4.replace(/\D|^0+/g, ""));
要运行上述程序,您需要使用以下命令-
node fileName.js.
输出结果
在这里,我的文件名为demo101.js。这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo101.js 5001000 100000005 5000001 6456
