Find the first string after character

I am trying to find the first character after a special character. For example: String: dog/11/99 I want jQuery to find 1(the character after the first /) and then 9(the character after the second /)

<table border="1">
   <tr><td class="abc">apple</td></tr>
   <tr><td class="abc">ball</td></tr>
   <tr><td class="abc">cat/55/77</td></tr>
   <tr><td class="abc">dog/11/99</td></tr>
</table>

I need to look through the whole table and then give me the character after the special character.

Any idea how I can accomplish that?

You can use .match() with RegExp /\W/ to match character that is not a word character, .index of returned array, String.prototype.slice(), bracket notation to get selected character at index of string.

var str = document.querySelector("table tr:last-child td").textContent;
var index = str.match(/\W/).index;
var res1 = str[index + 1];
var res2 = str.slice(index, str.length).match(/\W/).index;
var res2 = str[
             str.slice(index + 1, str.length).match(/\W/).index + 1 
             + index + 1
           ];

console.log(res1, res2);
<table border="1">
   <tr><td class="abc">apple</td></tr>
   <tr><td class="abc">ball</td></tr>
   <tr><td class="abc">cat/55/77</td></tr>
   <tr><td class="abc">dog/11/99</td></tr>
</table>

Try using the Regex:

/\/(.)/g

That will return the first character after any /.
For example:

var match, regex = /\/(.)/g;
while (match = regex.exec('dog/11/99')) console.log(match);
// ["/1", "1", index: 3, input: "dog/11/99"]
// ["/9", "9", index: 6, input: "dog/11/99"]

with match[1] being your desired character.
