I'm using Dynamic Data 4 on my project.
In a template field there's a button that modify (via javascript) the value of the databound input field.
The button modify the input box value correctly but when the input field get the focus his value it's resetted to the previous value. The same happens when saving the form. If the input box previously received input from the keyboard the value it's correctly stored.
Is that behaviour to be considered normal with those premises? There's a way to avoid it?
Thank you very much.
The problem was caused by the presence of an associated asp:TextBoxWatermarkExtender who resetted the value when the (originally null) textbox got the focus.

Using twitter's typeahead library https://twitter.github.io, if you attempt to update an inputs value with javascript (or jQuery), the value is reset to its original value when the input is selected, and then you click away.
See this gif below

As you can see the typeahead form (with id team2) first contains the string randomstring
When updated with $("#team2").val("test") the change can be seen in the input, but when you select the input and then click away it resets.
Values only seem to persist if you select the box and type in the value.
I need a way where I can alter the value through a js command.
I am working on customJs for swagger.
There I want to fill out an input field in advance for my use case.
Basically I can't see the code attached to the input field generated by swagger, but I can fill the input field with inputElement.setAttribute('value',"some stuff" )
But this does not trigger function as it seems, because when I proceed to use the submit button, it says the field is empty, only after I MANUALLY typed a letter and removed it, it recognized my changes.
Can I somehow trigger whatever the underlying function might be?
I want to change the value of an input field with javascript - WITH BROWSER CONSOLE.
I tried
$('input[name="anumber"]').val('200').change();
and
$('input[name="anumber"]').val('200').trigger('change');
So the value changes for half a second to 200 but then changes again back to the original number. Is the website preventing my input and how can I still input something without typing on my keyboard?
Any Help?
I have many controls(like texbox,telerik grid, dropdown and radio button) on one asp panel.Could someone help me in detecting changes in any control of asp panel while clicking submit button.
There might be a better way of doing this, but my suggestion would be:
Create a hidden field that has a default value of "False". This hidden field will tell us if the form has changed or not.
Then assigning any editable control the JavaScript OnChange event.
The OnChange event should call a simple method that sets the value of the hidden field to "True".
For example with jQuery it would be:
function FormChanged() {
$(".hiddenField").val("True");
}
Then when you submit you will be able to access the value of the hidden field to know wether the form has benn changed or not.
I have a knockout model with observable arrays bound to a table. I want to have a button that when clicked, doubles the focused textbox value. I want to do this without having a create a 'hasFocus' observable for every textbox or every ko observable. Couple of issues I experienced :-
if the button just edits the value of the textbox directly using jQuery, the ko value does not get updated. I need a way to tell the button to change the underlying value
if I focus on a textbox then click a button, the focus on the textbox is lost so client side also doesn't remember what textbox is focused
Do an event binding on input on both focus and blur, setting and clearing an observable which tracks what input is active.
When the button is clicked you know which value to double
