like below fixes the issue I would do this slightly different, if I understand your requirements. If when you click on a cell you need to do something to the previous clicked cell, use a class. So:

may help you . To select the
, use the .parent() function. However, since you are using HTML function, you will have to pass this to the function. Try this:
code :
function somefunction(myInputBox){
  var myInput = $(myInputBox).parent()[0];
  myInput.setAttribute('customattribute', $(myInputBox).val());
  //this line is just for testing.
  alert(myInput.attributes['customattribute'].value);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr><td customattribute="1"><input type='text' onchange='somefunction(this);'></td></tr>
<tr><td customattribute="2"><input type='text' onchange='somefunction(this);'></td></tr>
</table>
$("input").change(function() {
  var myInput = $(this).parent();
  myInput.attr('customattribute', $(this).val());
  alert(myInput.attr('customattribute'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table>
<tr><td customattribute="1"><input type='text'></td></tr>
<tr><td customattribute="2"><input type='text'></td></tr>
</table>

To fix the issue you can do Take a look at this fiddle: https://jsfiddle.net/3fh4mLba/1/
Basically, adding $(".switch").text("Off"); will set the text to "Off" for all of them before you change it to on.
fill in entire dataframe cell by cell based on index AND column names?

This might help you Turns out there's an even better way to do this. onepan's dictionary comprehension answer above is good but returns the df index and columns in random order. Using a nested .apply() accomplishes the same thing at about the same speed and doesn't change the row/column order. The key is to not get hung up on naming the df's rows and columns first and filling in the values second. Instead, do it the other way around, initially treating the future index and columns as standalone pandas Series.
code :
series_rows = pd.Series(['afghijklde', 'afghijklmde', 'ade', 'afghilmde', 'amde'])
series_cols = pd.Series(['ae', 'azde', 'afgle', 'arlde', 'afghijklbcmde'])

df = pd.DataFrame(series_rows.apply(lambda x: series_cols.apply(lambda y: edit_distance(x, y))))
df.index = series_rows
df.columns = series_cols

fixed the issue. Will look into that further rowspan means "This cell occupies this row and the next row".
There is no next row in your HTML.
