Question

我有一个完美运行的BMI计算器，但我的客户现在想让用户能够从其当前CMs + KGs的测量值切换到提供石头，英尺和英寸。我不完全确定如何转换它。

我的代码如下：

$("#height").bind(
    "slider:changed", function (event, data) {              
        $("#height_value").html(data.value.toFixed(0)); 
        calculateBMI();
    }
    );

$("#weight").bind(
    "slider:changed", function (event, data) {              
        $("#weight_value").html(data.value.toFixed(0)); 
        calculateBMI();
    }
    );

function calculateBMI(){
    var weight = $("#weight_value").html();
    var height = parseInt($("#height_value").html())/100;
    var bmi = weight / (height * height);

    var type = "Normal";

    var imageResult = $('#image-result');
    var classes = 'underweight overweight obese very-obese normal-weight';

    if (bmi < 15){
        type= "Score below 20: Underweight";
        imageResult.removeClass(classes);
        imageResult.addClass('underweight');
    }else if(bmi <=24.9){
        type= "Score: 20-25: Normal Weight";
        imageResult.removeClass(classes);
        imageResult.addClass('normal-weight');
    }else if(bmi <=29.9){
        type= "Score 26-30:Overweight";
        imageResult.removeClass(classes);
        imageResult.addClass('overweight');
    }else if(bmi <=34.9){
        type= "Score 31-40:Obese";
        imageResult.removeClass(classes);
        imageResult.addClass('obese');
    }else{
        type= "Score: 40+:Very Obese";
        imageResult.removeClass(classes);
        imageResult.addClass('very-obese');
    }
    $("#result").html("<small>"+type+"</small>");
    $('#bmi-index').html(bmi.toFixed(1));
}
calculateBMI();

非常感谢您的帮助！

没关系。我设法通过插入这个来转换它：

$("#height").bind(
    "slider:changed", function (event, data) {              
        $("#height_value").html(data.value.toFixed(0)); 
        var inches = (data.value*0.393700787).toFixed(0);
        var feet = Math.floor(inches / 12);
        inches %= 12;
        $("#height_value_in").html(feet + "ft " + inches + 'in');
        calculateBMI();
    }
    );

$("#weight").bind(
    "slider:changed", function (event, data) {              
        $("#weight_value").html(data.value.toFixed(0)); 
        $("#weight_value_pounds").html((data.value*2.20462).toFixed(0) + 'lb' );
        calculateBMI();
    }
    );

jQuery Calculator转换为英尺/英寸
