Execute additional javascript as document ready ? Or Table Editor with selected all lines by default

KNIME Server
1

Hello all,

I want to view a table with all lines selected by default.
This is not configurable with the current Table Editor, so I want to do it with Generic JavaScript View, cf. attached workflow
Test_JS.knwf (10.6 KB)
However, this does not work ! I suppose that I mis-use the Generic JavaScript View node ?
Can someone please tell me how to pre-selected all the lines of the table at first view ? with JS or another way ?

Thanks in advance

Hi,
so far I have not managed to trigger this code when the iframe is loaded and the checkboxes are actually available, but this code sets them all to checked:

$(window.top.document).find("iframe").contents().find("iframe").contents().find("input[type=checkbox]").prop("checked", true);

This is necessary because there are some iframes in the window (one top level and one for each widget).
I simplified the selector a bit for readability. Feel free to change it back to yours. I will continue to search for a solution, but maybe you have an idea how to proceed from here.
Kind regards
Alexander

Hi,
one more idea, not perfect, but working:

var token = setInterval(() => {
var inputs = $(window.top.document).find("iframe").contents().find("iframe").contents().find("input");
    if (inputs.length > 0) {
	    inputs.prop("checked", true);
	    clearInterval(token);
    }
}, 500);

This just checks for the iframes in 500ms intervals and when they are available sets the checkboxes.
Kind regards
Alexander

Hi Alexander,

Thanks for your answers.

I’ve tried the solution that you proposed. It works fine locally, but when I deploy the workflow on the Knime Server, it does not work. I do not really understand the difference ?!!!

However, I found this old thread Custom javascript functions in the HTML page generated by quick forms
And based on this, I made it works locally and also on the Knime server…

Thanks again and have a nice day!
