I have a drop down list and a input field on the page using MVC. I use JQuery to get the value from Controller to set value for this input field depends on the drop down list selection. I noticed the input field is populated on the page, but the value attribute is still empty checked using browser Developer Tool. I use
@Html.EditorFor(model => model.inputFieldID, new { htmlAttributes = new { @id = "inputFieldID"} })
In JQuery ajax I set the value like:
$("#inputFieldID").val(NewValueFromDB);
and I can see value is set using
alert($("#inputFieldID").val());
but on the page, the value attribute field is empty, what did I miss?
UPDATE:
I figured out that because I try to make the input field not editable, so I gave @disabled = "disabled" to it. That seems stopping the value get passed to Controller.
But my question is, if I want to make the input field not editable, but still can pass the value to Controller what should I do?
ANSWER Use readonly instead of disabled attribute and give a grey background-color to make it look like not editable.
Thank you.
The jQuery .val() method updates the element's value property and not the attribute value.
The attribute is mainly used to initialize the property.
Normally you do not have a need for the value attribute of input elements.
