Javascript - Assign The Correct Value To A Textbox?
Sep 23, 2010
I am passing in a value to the form that I ultimately assign to a textbox using javascript. The value is a calculation based on values from another page/form. However, the textbox is editable.
When reloading the form with the previously saved data, I don't want the value of the textbox to be overwritten with the pre-calculated value from another page if it was edited manually upon save.
The other stipulation is, the page/form that has the values that the calculation is created from, can be changed. Therefore, I would also want to check to see if the calculated value has changed since last load, and if so, load that over the manually entered value.
So...
If textbox is blank populate with calculated value else if Manually entered value trumps calculated value else if calculated value has changed since last calculation, it trumps manually entered value.
The other concern with this all, is how do I determine if the user has typed in the textbox to determine if the value was manually entered?
I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
