![]() ![]() Use the querySelector() method to check whether a radio button is selected Output.innerHTML = "The radio button is selected and it's value is " + radio.value Let radioButtons = document.getElementsByName('radio') Using the checked property of the radio button to check whether a radio button is selected The getElementByName() method returns all radio elements with the name radio.Īfter that, we used the for-of loop to iterate through the array of radio buttons and check for every radio button using the ‘checked’ property whether the radio button is selected. The example below is almost the same as the one above, but the difference is that we are accessing all radio buttons using their name at once. ![]() Output.innerHTML = "The radio button with value " + radio3.value + " is checked!" Output.innerHTML = "The radio button with value " + radio2.value + " is checked!" Output.innerHTML = "The radio button with value " + radio1.value + " is checked!" checking if any radio button is selected Let radio3 = document.getElementById('radio3') Let radio2 = document.getElementById('radio2') Let output = document.getElementById("output") Using the checked property of the radio button to check whether a radio button is selected. When the user selects any radio button and clicks on the button, they see a message showing the value of the selected radio button. In JavaScript, we have accessed each radio button by its id and checked the value of every radio button's ‘checked’ property. In the example below, we have created three radio buttons containing different values, such as male, female, and others. In the above syntax, we have accessed the radio button using its id and used the checked attribute to check whether the radio button is selected in the if-statement. Let radio1 = document.getElementById('radio1') Users can follow the syntax below to check whether the radio button is selected using the checked property of the radio element. If the value of the checked property is true, it means the radio button is selected otherwise, it’s not selected. After that, we can use its checked property to check whether the selected radio button is checked. We can access the radio element in JavaScript using various methods. Using the checked property of the radio button In this tutorial, we will learn two approaches to checking whether a radio button is selected using JavaScript. When you fill out any form and ask to choose a gender, you can see they give you three options, and you can select only one. Let’s understand it via real-life examples. So, it is important to check which radio button the user selects to know their choice from multiple options. Users can select any option, and we can get its value and know which option users have selected from the multiple options. ![]() I have seen how to reference a Radio Button, and how to reference a Virtual Field, but haven't seen how to reference a Radio Button that is part of a Virtual Field.In the HTML, the radio buttons allow developers to create multiple options for a choice. I know that Radio Buttons are referenced differently, but I have tried some variations and haven't been able to make it work. If you open the link, you will see that the Virtual2 (Text Field) works, but the Virtual1 (Radio Button) doesn't. This is the code I currently have in the Footer of the Data Page:ĭocument.getElementById("cbParamVirtual1").value="AAA" ĭocument.getElementById("cbParamVirtual2").value="AAA" It's a test form that I am using just to not mess up the main one: What I want to do is change the first option on a radio button, which belongs to a virtual field. I do have the code in the Footer section of the Data Page, and i can make the code work on a virtual field that is text. Hello Caspio Evangelist, and thank you for your help! Is it possible to do what I am trying to do with a Virtual Field? If it is, how can I make it work? I appreciate your help! X is the radio button option order, which starts at 0 and increments based on the order of each radio option.įor example if your radio button has three options: Red, Blue, Green Radio Button: A radio button includes multiple options and each option has an associated ID.I have also change it used " getElementById", and change the statement inside the parenthesis with " InsertRecordVirtual1 0", that last one based on what I found here: Here's the code I'm currently using:ĭocument.getElementByname("InsertRecordVirtual1").value="AAA" Is it possible to condition the values of a radiobutton using Javascript? What I want to do is that, when the Data Page loads, checks if it meets a condition, and if it does, based on that is the value of the first option of my radiobutton. I haven't been able to make the first part work, and i want to make sure that works before adding the 'If' statement.
