Remember that the height, weight, and activity are all string and you need to convert it to a number in order to do any operation such as bmr = (66.5 + (13.75 * weight) + (5.003 * height) + (6.755 * age)) * 1.53 īut the Switch case you have is asking for a string '1.53, 1.76, 2. you can get the value of activity by checking each loop of the elements activityĪfter you get the value of the activity. if radio button is checked, set the value Var elements_activity = document.getElementsByName('activity') Var activity = document.getElementsByName("activity").value Var weight = document.getElementsByName("weight").value Var height = document.getElementsByName("height").value Var gender = document.getElementsByName("gender").value Var age = document.getElementsByName("age").Value This is what I wrote below so far: You just enter your height in CM and enter weight in Kilograms.But, when I will calculate the BMR, the button isn't working. I have created an application to calculate BMR.
