Get right 2 charcters from an input to another input

Question

I have input in one field:

<td>
    Main Category   
    <select  id="category" name="category" class="form-control">
        <option value=""></option>
        <option value="Non-Current Asset">Non-Current Asset 11</option>
        <option value="Current Asset">Current Asset 12</option>
        <option value="Non-Current Liability">Non-Current Liability 21</option>
        <option value="Current Liability">Current Liability 22</option>
        <option value="Cost of Sales">Cost of Sales 23</option>
        <option value="Operating Expenses">Operating Expenses 31</option>
        <option value="Selling Expenses">Selling Expenses 32</option>
        <option value="Operating Income">Operating Income 41</option>
        <option value="Other Income">Other Income 42</option>
        <option value="Equity">Equity 51</option>
    </select>
</td>

So if I select "Non-Current Asset 11" from drop down, I want the right 2 characters "11" entered in another input field automatically. Other input field is as follows:

<td>
    Main Code
    <input id="main_code" type="text" name="main_code" readonly />
</td>

You should not. Much better to use value or some data attribute for this, like `data-id="11"`. — vp_arth, Jan 18 '17 at 08:07

Pierre, I know your concern is CSS3 in my requirements. I put it as somewhere I read that now CSS is more than just styling. Thanks — Abdul, Jan 18 '17 at 09:08

It seems that you have same text in value attribute of option and in text you have numbers.

What you can do

Write javascript function which will remove the text from text value of option based on the selected value. Then only number will remain which you can user\pass to other input.

Thanks Rahul, I am new to web development and still am unable to extract / cut the string. Can you kindly provide the simplest solution to this issue using HTML5? If not then in CSS3, Javascript or jQuery. – Abdul Jan 18 '17 at 08:09

I solved it myself as follows with HTML5

changed the selection as follows;

 <td>Main Category   <select  id="category" name="category" class="form-control" required oninput="main_code.value = parseInt(category.value)">
                  <option value=""></option>
                  <option value="11">Non-Current Asset 11</option>
                  <option value="12">Current Asset 12</option>
                  <option value="21">Non-Current Liability 21</option>
                  <option value="22">Current Liability 22</option>
                  <option value="23">Cost of Sales 23</option>
                  <option value="31">Operating Expenses 31</option>
                  <option value="32">Selling Expenses 32</option>
                  <option value="41">Operating Income 41</option>
                  <option value="42">Other Income 42</option>
                  <option value="51">Equity 51</option>
                  </select></td>

Done

Use javascript to get the text of selected option and replace all other characters from string.

<script>
    function jsfunction(element)
    {
        var text = element.options[element.selectedIndex].text;
        text = text.replace(/[^0-9]/g, '');
        document.getElementById("main_code").value=text;
    }
</script>

Main Category
Non-Current Asset 11 Current Asset 12 Non-Current Liability 21 Current Liability 22 Cost of Sales 23 Operating Expenses 31 Selling Expenses 32 Operating Income 41 Other Income 42 Equity 51

Main Code       
<input id="main_code" type="text" name="main_code" readonly />
