radio-button

问题 this is a similar issue to what is mentioned in a related post but I thought it was different enough to get its own question. Here it goes: I have been able to get the "radio circle" to disappear no problem when declaring the radio buttons in xml by setting the button attribute of the radio button to null like this: <RadioButton android:id="@+id/radioButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="One" android:background="@drawable/radio_button

问题 If I have several radio buttons of the same name, only one can be selected at any one time. When one becomes selected, any namesakes lose their selection. I'm intrigued as to why this doesn't constitute a .change() event for jQuery. Hacking the $.change() function would be pretty drastic, but this doesn't seem to be reported as a bug — so I'm interested in finding out why this isn't the case. Test below: I'd expect the two change events to fire whenever a radio is selected, but that isn't the

问题 From this and this (and other) questions on SO and many other material on internet, I understood how to bind radio button with VM. But all of them create separate property for each possible value of radio button. One question (this) is similar to my requirement but the accepted answer suggests to use ListBox instead of radio button. To represent person gender (Datatype CHAR, Possible values 'M', 'F'), three properties needs to be created in VM as PersonGender, IsPersonMale, IsPersonFemale. I

问题 I need to built a list of radio buttons, based on data I return from my DB. Each button needs to have a value associated with it that I can get out based on the selected button. Ideally I would just use the RadioButtonList control, however, I need to have a very custom layout which a RadioButtonList doesn't appear to be able to handle. An alternative would be to create individual RadioButton s and wrap them in a Panel to group them. However, there doesn't appear to be a Value property on a

问题 I have two radio buttons with the same name, one is checked by default. How can you check or uncheck a radio button in jQuery when selecting from id? I've tried: $('#radio1').attr('checked','checked'); $('#radio1').attr('checked', true); Nothing seems to work.. any ideas? Thank you! 回答1: You can not have same id ( #radio1 ) more than once, use a class instead. $('.radio1').attr('checked', true); $('.radio2').attr('checked', true); The id should be used once per element per page. If you want

问题 Please see this: http://gisdev.clemson.edu/fireflies Toward the top right are three checkboxes and I am trying to make them work like radio buttons. Part of the programming is working but here is something which is problematic: Initially, the 'Counties' checkbox is checked. And if I were to click on the 'Hydric Soil Rating' checkbox and then click back on the Counties checkbox the Hydric checkbox still stays checked. The console doesn't output anything, meaning the value of checkboxes

问题 I'm working on a Shiny app that enables folk to browse some time series data. I have a number of widgets that enable people to select variables and type of analysis. In between, I have a modest radioButton mechanism that allows users to select time series for some variables: radioButtons("radio_year_select","Year", c("1999" = "1999", "2001" = "2001"))), The code generates a simple widget: In the context of this particular application, I would like to have the options presented in a horizontal
