问题 I have a simple input field inside a form tag: <body> <form action="#"> <label>Input</label> <input type="hidden" id="foo" name="foo" /> </form> </body> I tried to set this value from a js file: $(document).ready(function(){ $('#foo').val('foo') }) but in the html source the attribute isn't set at all. If I try to set the input type to "button" or anything else, it works. I just can't do it with a hidden input field. What am I doing wrong? 回答1: Can you retrieve the value from the hidden field

Why does my HiddenField fail on a second attempt to instantiate?

由 守給你的承諾、 提交于 2019-12-12 03:18:53
问题 On my web page, almost all the elements (which are divided into panels/divs) are created dynamically only after the user selects one of two choices (show this or show that). After a form submission, though, the form returns to its original pristne/austere state.
