Replace Number in string in jquery

Question

I want to replace a number withing string since it can be done in regex but i don't know much about it here's my code

var rowNo=6;
var tName=jQuery(this).attr('name');

tName will be in this format

input_[3][InvoiceNo]

and I want to remove 3 and replace with rowNo value in regex what i tried was this

replace(/[0-9]+/, rowNo)

but this replaces all numbers with rowNo. I don't want to do that, what I want is to replace 3 with rowNo.

Replace number inside []

replace(/\[[0-9]+\]/, '['+rowNo+']')

var str = 'input_[3][InvoiceNo]',
  rowNo = 4;
alert(str.replace(/\[[0-9]+\]/, '[' + rowNo + ']'));

Replace number with brackets,

var rowNo = 8;
var str = 'input_[3][InvoiceNo]';

alert(str.replace(/\[\d+\]/, '[' + rowNo + ']')); // returns input_[8][InvoiceNo]

You can include [] to find string to be replaced

.replace(/\[[0-9]\]+/, "[" + rowNo +"]")

var str = "input_[3][InvoiceNo_8_9]";    
var rowNo = 6;
str = str.replace(/\[[0-9]\]+/, "[" + rowNo +"]")
document.write(str);
