Can't get to nested table

in Getting Started • 10 years ago

Hi everyone,

I develop pages within a third party web application. The page output has tables within tables. I have an 'id' for the table I want, 'oErrorsList' which I then want to find the value of 'SelectedRowID'. I have tried the following code but I get nothing.

var myTable.text = $('table').filter('[id=oErrorsList]').SelectedRowID;
alert(myTable);

I am new to this forum and I don't know if this is enough information so I am including an image of part of the page. Thanks very much for any help given.

if you know the id of the row you want, go directly to it:

var tempvar = $('#selectedrowid').text();

alert(tempvar);

keep in mind, however, that ID's cannot start with a number. Because of this, you may not be able to select by ID in some browsers when the ID starts with a number.

Hi Kevin,

I pasted your suggestion in and I got the alert but it was blank. Anything else?

I have this function attached to a button:

         function fnTesting()
            {
                alert('test');
                var tempvar = $('#SelectedRowID').text();
                alert(tempvar);
//                var myTable.text = $('table').filter('[id=oErrorsList]').SelectedRowID;
//                alert(myTable);
            }

more than likely you need something more like this:

var selectedRowID = $('#oErrorsList').attr('SelectedRowID');

var tempvar = $('#' + selectedRowID).text();

alert(tempvar);

Hi, I use the following and got the first 'test' alert but not the second.

         function fnTesting()
            {
                alert('test');
//                var tempvar = $('#SelectedRowID').text();
//                alert(tempvar);
                var selectedRowID = $('#oErrorsList').attr('SelectedRowID');
                var tempvar = $('#' + SelectedRowID).text();
                alert(tempvar);
//                var myTable.text = $('table').filter('[id=oErrorsList]').SelectedRowID;
//                alert(myTable);
            }

you capitalized the second use of the selectedRowID Variable. javascript is case-sensitive.

Hi, I corrected the mistake and got the second alert but it was empty.

         function fnTesting()
            {
                alert('test');
//                var tempvar = $('#SelectedRowID').text();
//                alert(tempvar);
                var selectedRowID = $('#oErrorsList').attr('SelectedRowID');
                var tempvar = $('#' + selectedRowID).text();
                alert(tempvar);
//                var myTable.text = $('table').filter('[id=oErrorsList]').SelectedRowID;
//                alert(myTable);
            }

try this to ensure you are getting a selected row id

var selectedRowID = $('#oErrorsList').attr('SelectedRowID');

alert(selectedRowID)

more than likely it is failing because either the id is not unique or in the browser you are testing in id's can't start with numbers.

Hi Kevin,

I looked for duplicate 'oErrorsList' and found something. I removed it and then tested with the following. I got the first 'test' alert, the second alert was blank, and the third alert had all the text that was in the selected row - but not the id itself !! Yahoo, progress!!

         function fnTesting()
            {
                alert('test');
                var tempvar = $('#SelectedRowID').text();
                alert(tempvar);
                var selectedRowID = $('#oErrorsList').attr('SelectedRowID');
                var tempvar2 = $('#' + selectedRowID).text();
                alert(tempvar2);
//                var myTable.text = $('table').filter('[id=oErrorsList]').SelectedRowID;
//                alert(myTable);
            }

yeah it won't have the id since the id is an attribute in the tr html element. you have the id already in the selectedRowID variable, just add it to the alert.

alert(selectedRowID + tempvar2);
