下面的函数将执行线性归一化(感谢 SMcCrohan) 并且您可以将您需要的值传递给它.

The function below will perform linear normalization (thanks S McCrohan) and you can pass it the values you'll need.

https://jsfiddle.net/7cn57wnd/

function normalize(enteredValue, minEntry, maxEntry, normalizedMin, normalizedMax) {

    var mx = (enteredValue-minEntry)/(maxEntry-minEntry);
    var preshiftNormalized = mx*(normalizedMax-normalizedMin);
    var shiftedNormalized = preshiftNormalized + normalizedMin;

    return shiftedNormalized;

}

//Acceptable values: 0 - 10,000,000
//User enters: 99,000,000
//Normalization window: 200 - 3800

normalize(99000000, 0, 100000000, 200, 3800);

//Returns 3764
