Hi,

JavaScript is a case sensitive language.

If you change the line of code:

Code: Select all

tables.myWorldDiscounts.fetchTable();

to

Code: Select all

tables.myWorldDiscounts.fetchtable();

This should fix your problem.

Also I see on the next line you should call:

Code: Select all

controls.table1.show();

to show the table. You are missing the () at the end.

I hope this helps

' "fetchtable" of undefined '

Hi,

Sorry I misinformed you. The syntax should be fetchTable with a capital T. I misread the error. The error is suggesting that the table does not exist on the form.

Code: Select all

tables.myWorldDiscounts.fetchTable();

Is the table name correct for the fetchTable() function? Does myWorldDiscounts exist in the form?

Your last screen shot link did not work, so perhaps you can send me a screen shot of the Form - 'firstForm'

Kind regards

Steve

thanks, i actually redid the entire resource attachment and the table is displaying... BUT, the button event returns an error , the text box should display a message of the users first and last name... here is a screenshot, of error, code, and setup...

Hi,

You need to modify the line:

Code: Select all

controls.text1.text.text = fields.firstName + fields.lastName

to

Code: Select all

controls.text1.text.text = "welcome " + fields.firstName.value + " " + fields.lastName.value 

The important part here is the .value at the end of the field name you are referencing ... this returns the actual value of the field.


Kind regards

thanks Steve, it fixed it and i learned something...

is there a way to debug the JS script for syntax or other errors? do you have suggestions

[Steve]

The JavaScript editor has syntax checking inside it. If there is a red syntax error (little squiggle), you can hover over it and it will tell you the error.

There is no interactive debugger though for JavaScript. This would be a nice edition to Ebase.
