How to stop onChange in JavaScript

Question

In one of my selection boxes, I have an onChange="..." specified... because I want to change some other form value after any selection changes.

However, in the same page, some weird case I have to manually set the value. So I have to use some JavaScript to set the value of the selection combobox, but in this case, I don't want that onChange event to be fired.

How can I walk around it?

Forgot to mention that I am actually using dijit.form.comboBox. For normal HTML form comboBox, it won't cause any issue. Only I use the dijit comboBox, and I try to set the value to some other value, dojo will trigger the onChange.

If you are using Dijit, then you can pass an additional false flag at the end of the set() method that will prevent the widget from firing the onChange event.

For example:

dijit.byId(myComboBox).set("value","Choose an option...",false);
