获得第一个角色后的一切

Question

是否可以在第一个字符后获取所有字符串？

var val = 'asdasd:111122:123123123';
var response = val.substring(val.lastIndexOf(":")+1);

alert(response ); // "123123123"
// Would like: ":111122:123123123"

谢谢！

Answer 1

使用indexOf(...)代替lastIndexOf(...)

如果要包含":"，请不要在索引中添加一个。

像这样：

＆＃13;

＆＃13;

var val = 'asdasd:111122:123123123';
var response = val.substring(val.indexOf(":"));

alert(response); // ":111122:123123123"

＆＃13;

＆＃13;

＆＃13;

Answer 2

var mobileWithCode="+91-9842505145";//mobile value with nation code

mobile = mobileWithCode.substring(mobileWithCode.indexof("-"));

alert(mobile);

Answer 3

只需删除+1并继续您的代码将正常工作

var response = val.substring(val.lastIndexOf(":"));

alert(response); // Would Become: ":111122:123123123"
