如何检查是否正在使用一个元素,以及是否要在Switch Case语句中使用另一个元素。
@snapshot = {
captable: @captable,
evet: @event,
shareholders: @shareholders
}
//Input
function myFunction() {
var myArray = ["60","50", "20", "30", "15", "10"];
var randomJumpingJacks = myArray[Math.floor(Math.random()*myArray.length)];
var randomCrunches = myArray[Math.floor(Math.random()*myArray.length)];
var workOut = document.getElementById("myInput").value;
var text = "";
for(const char of workOut.toUpperCase()){
switch(char) {
case "A":
case "I":
case "N":
case "X":
text += randomJumpingJacks;
text += " Jumping Jacks";
break;
case "B":
case "J":
case "Q":
case "Y":
text += randomCrunches;
text += " Crunches";
break;
case " ":
/*text += " break ";*/
break;
default:
text += "I have never heard of that fruit...";
}
text +=" "
text +="<br>"
}
document.getElementById("excercise").innerHTML = text;
}
示例: 我输入了:ABBY 我希望它能输出:
10个跳插孔
15个仰卧起坐
10个仰卧起坐
20个仰卧起坐
我不确定我是否使用正确的术语,但是我将案例A,I,N,X称为“跳跃块”,将案例B,J,Q,Y称为“紧缩块”。
如果调用的字符来自同一块,则倾向于显示相同的随机数。
在Crunches块的第二个字符(B)上,它自然输出15,但是由于它被用于第一个字符(也为B),我希望它使用其他元素,
,第三个字符(Y)也在Crunches块上,我希望它使用与前两个元素不同的其他元素,依此类推,并重复4次。
我很想知道你的想法。

您需要将随机逻辑移至for循环内。要获得字符串中每个字母的新随机数,您需要在每次循环执行时重新分配该值。请参见下面的代码。
function myFunction() {
var myArray = ["60","50", "20", "30", "15", "10"];
var workOut = document.getElementById("myInput").value;
var text = "";
for(const char of workOut.toUpperCase()){
var randomJumpingJacks = myArray[Math.floor(Math.random()*myArray.length)];
var randomCrunches = myArray[Math.floor(Math.random()*myArray.length)];
switch(char) {
case "A":
case "I":
case "N":
case "X":
text += randomJumpingJacks;
text += " Jumping Jacks";
break;
case "B":
case "J":
case "Q":
case "Y":
text += randomCrunches;
text += " Crunches";
break;
case " ":
/*text += " break ";*/
break;
default:
text += "I have never heard of that fruit...";
}
text +=" "
text +="<br>"
}
document.getElementById("excercise").innerHTML = text;
}
