H5 Script - Block User Input until Script Complete

Hi all,

We have a particular script that has to run using an async function, with a series of await API calls during it's execution.

There are a number of API calls being made during the script execution, and occasionally the user is able to F3 out of the panel prior to the script completing it's execution.

Does anyone know how we can block user input, after a script has been triggered (onRequesting), until the script has completed?

This might be blocking user input, or as per normal M3, throwing up a loading animation until finished.

Any ideas?

Regards,

Iain

Very good question

public static Init(e: IScriptArgs): void {
const host$ = $('#' + e.controller.ParentWindow.attr('id'))
host$.append('<div id="pDiv" style="position:absolute;top:0;left:0;width:100%;height:100%;z-index:2;opacity:0.4;filter:alpha(opacity=50)"></div>');
setTimeout(() => { host$.find('#pDiv').remove() },3000)

new xxxx(e).run()'
}

You can put host$.find('#pDiv').remove() in any other part of Script of course.

Thanks Antonio

I can see how that works, it's good.

Hi Antonio,

Just a follow up question, I want to block the user input based on a certain condition being met during the execution of the onRequesting() function. When I put the code in there it doesn't seem to work.

How would you implement blocking the user input from onRequesting(), while allowing the rest of the script to continue and complete?

Cheers,

Iain

It works but has some conditions.

Send me You OnRequesting code.

Hi - code below. Basically, it's checking whether the user has allocated more than one lot to the line, and if so, it calls "manipulateCOLines" function. We need to block the user from being able to "F3" until that function has completed.
