how to convert vbscript Mid function to javascript with 2 arguments?

Question

    nHighlightedRow = Mid(string, 2, 11)  

I can convert this like ,

    var nHighlightedRow = string.subStr(2-1,11)

but I have to convert this,

    nHighlightedRow = Mid(string, 11)

can I convert this as follow ?

    var nHighlightedRow = string.subStr(0,11)

Answer 1

no.

it would be string.substring(11-1) .

Answer 2

不， Mid(string,11)从字符11提取到字符串的末尾， string.substring(0,11)从字符1提取，您将需要string.substring(10)
