Jquery string find with regex and replace with add one

Question

This is my string

<input name="e8[1][4]" value="" type="hidden">
<input name="e10[1][4]" value="" type="hidden">
<input name="e8[1][4]" value="" type="hidden">
<input name="e10[1][4]" value="" type="hidden">
<input name="e6[1][4]" value="" type="hidden">
<input name="e9[1][4]" value="" type="hidden">
<input name="e6[1][4]" value="" type="hidden">

I have to change all second array element with +1. it shoud be my output

<input name="e8[1][5]" value="" type="hidden">
<input name="e10[1][5]" value="" type="hidden">
<input name="e8[1][5]" value="" type="hidden">
<input name="e10[1][5]" value="" type="hidden">
<input name="e6[1][5]" value="" type="hidden">
<input name="e9[1][5]" value="" type="hidden">
<input name="e6[1][5]" value="" type="hidden">

How I achieve this format with jquery or regexsolution. i make following regex to get last number of string how i work ahead

var patt1 = /(\d+)(?!.*\d)/;

Regex doesn't convert your groups to any value other than string. You'd need to convert to int to add +1 to all the values — abc123

how i pick 4 into string. it should be any number. but the number will be the same. ex in start it is 90 then all group it wil be the 90 — reena.sharam

not a fan of modifying html content using string operations... so here you go - jsfiddle.net/arunpjohny/547Pc/1 — Arun P Johny

Do this:

var result = 'string'.replace(/\d+(?=\]")/g, function (match) {
    var newNum = Number(match) + 1; // 5
    return newNum;
});
console.log(result);// replaced second number in array with +1
