Title: reset on textbox / datebox / combobox triggers onchange Post by: gordis gmbh on September 16, 2015, 09:47:46 AM I have a series of textboxes with onchange function implemented to submit the changed value to the database.
If the database delivers an error, I try to restore the component's oldvalue using 'setValue'. But the 'setValue' call triggers the onchange function again and as a result the submit gets called again - resulting in a never ending loop! Please find the demo here: http://jsfiddle.net/2xo0cyz9/ (http://jsfiddle.net/2xo0cyz9/) What am I doing wrong here? I dont want to call reset on the textbox. I want to restore the previous value. The same problem exists with date and comboboxes as well. Please help. Thanks.

The 'initValue' method changes the textbox value but does not trigger the 'onChange' event.

However, for comboboxes it doesn't behave like setValue but does setText: http://jsfiddle.net/2xo0cyz9/3/ (http://jsfiddle.net/2xo0cyz9/3/) Title: Re: reset on textbox / datebox / combobox triggers onchange Post by: stworthy on September 17, 2015, 06:17:45 AM Please try this updated example http://jsfiddle.net/2xo0cyz9/4/

It doesn't seem to work for me. When I call such rollback function during onChange event I get strange situation that value of combobox is reset to oldValue but in ui it looks like new value was selected. So I have combobox displaying "YES" but when I check its value it is "NO" Does anyone have runnig example how to successfully recover oldValue in combobox if for example database operation failed? |
