Javascript 变量不'；t使用if语句进行更改
我面临Java脚本的问题。 我有一段代码在div中创建rain，我需要根据if语句关闭和打开rain 下面是使rain工作的JS代码Javascript 变量不'；t使用if语句进行更改,javascript,html,css,Javascript,Html,Css,我面临Java脚本的问题。 我有一段代码在div中创建rain，我需要根据if语句关闭和打开rain 下面是使rain工作的JS代码 var nbDrop = 120; // function to generate a random number range. function randRange( minNum, maxNum) { return (Math.floor(Math.random() * (maxNum - minNum + 1)) + minNum); } // fu
var nbDrop = 120;
// function to generate a random number range.
function randRange( minNum, maxNum) {
return (Math.floor(Math.random() * (maxNum - minNum + 1)) + minNum);

}
createRain();
var nbDrop=120；
//函数生成一个随机数范围。
函数randRange（minNum、maxNum）{
返回（Math.floor（Math.random（）*（maxNum-minNum+1））+minNum）；
}
//函数生成水滴
函数createRain（）{
对于（i=1；i1）：您应该删除条件==5中的“var”，因为它已经声明了
else if (chosenAnswer == 5){
// var nbDrop = 120;
nbDrop = 120;
2:当nbDrop为0时，注释的方法将不会运行，因为i
从1开始，并且1永远不能小于0
function createRain() {
// for( i=1;i<nbDrop;i++) {
for( i=0;i<=nbDrop;i++) { // need to be like this
