Possible to have Multiple Triggers?

1

Hi,

If I have a child table with multiple fields that I would like to trigger on, how can I achieve this?

For e.g., in the function below, I can currently trigger area calculation when the width is changed. But I would like to recalculate area when the length is changed as well.

Thanks

frappe.ui.form.on("Building Dimensions", "width", function(frm, cdt, cdn) {
	var total_area = 0.0;
	var dimensions = frm.doc.dimensions;
	for(var i in dimensions) {
		dimensions[i].area = dimensions[i].length * dimensions[i].width
		total_area += dimensions[i].area
	}
	frm.set_value("total_area",total_area)
	frm.set_value("total_area_sqft", total_area*10.76391)
 });

you can try refresh

frappe.ui.form.on("Building Dimensions", "refresh", function(frm, cdt, cdn) {
	//script
}

or make common function and call it on each field trigger.

frappe.ui.form.on("Building Dimensions", "length", function(frm, cdt, cdn) {
	common_function()
}

same for all fields

  frappe.ui.form.on("Building Dimensions", "width", function(frm, cdt, cdn) {
    	common_function()
    }

Thanks for the reply @Sangram

refresh doesn’t work (maybe since it’s a child table?)
Will use option two for now.

Thanks

Hi @ishanloya! How about refreshing the child table:

cur_frm.refresh_field("items")

@creamdory, thanks for your reply but I’m not sure how to go about doing that.

For now, I’ve followed @Sangram’s advice and changed my code to:

function area_calc(frm, cdt, cdn) {
	var total_area = 0.0;
	var dimensions = frm.doc.dimensions;
	for(var i in dimensions) {
		dimensions[i].area = dimensions[i].length * dimensions[i].width
		total_area += dimensions[i].area
	}
	frm.set_value("total_area",total_area)
	frm.set_value("total_area_sqft", total_area*10.76391)
}

frappe.ui.form.on("Building Dimensions", "length", area_calc)
frappe.ui.form.on("Building Dimensions", "width", area_calc)

Hi @ishanloya! It works like a refresh but on the child level. The “items” is the child doctype name. :wink:
