随机数,if,else if

Question

我正在写这样的JavaScript代码:

function rollTrigger() {
var roll = Math.round(Math.random()*999999999+1);
var result = document.getElementById("result");

if (roll <= 50900000) {
    result.innerHTML = "Category 0";
    BoLPamount += 1;
    document.getElementById("boxlesserprizes").innerHTML = "Box of Lesser Prizes " + BoLPamount; 
    log.innerHTML += "<br />Trigger - win = true; Category 0"; //LOG        
} else if (roll <= 900000) {
    result.innerHTML = "Category A";
    log.innerHTML += "<br />Trigger - win = true; Category A"; //LOG
} else if (roll <= 360000) {
    result.innerHTML = "Category B";
    log.innerHTML += "<br />Trigger - win = true; Category B"; //LOG
} else if (roll <= 211890) {
    result.innerHTML = "Category C";
    log.innerHTML += "<br />Trigger - win = true; Category C"; //LOG
} else if (roll <= 109020) {
    result.innerHTML = "Category D";
    log.innerHTML += "<br />Trigger - win = true; Category D"; //LOG
} else if (roll <= 56505) {
    result.innerHTML = "Category E";
    log.innerHTML += "<br />Trigger - win = true; Category E"; //LOG
} else if (roll <= 34888) {
    result.innerHTML = "Category F";
    log.innerHTML += "<br />Trigger - win = true; Category F"; //LOG
} else if (roll <= 15574) {
    result.innerHTML = "Category G";
    log.innerHTML += "<br />Trigger - win = true; Category G"; //LOG
} else {
    result.innerHTML = "MEH";
    log.innerHTML += "<br />Trigger - win = false"; //LOG
};
document.getElementById("roll").innerHTML = roll;

};

但是它没有正常工作......例如,如果随机数是40200000,那么它会显示"类别0",但是即使随机数为10,它仍然显示"类别0"而不是"类别G".有什么想法错了吗？

Answer 1

if (roll <= 50900000)
那么10小于50900000,不是吗？
颠倒if语句的顺序,一切都应该没问题.
