推荐答案
我使用 string.split修复了你的代码，没有任何外部库。您还尝试在目标输入上访问 valueB 时出现引用错误。
I fixed your code by using string.split, and without any external libraries. You also had a reference error trying to access valueB on the target input.
<!DOCTYPE html>
<html>
<head>
<script>
function check(browser) {
var splitValues = browser.split(';');
document.getElementById("answer").value=splitValues[0];
document.getElementById("answerB").value=splitValues[1];
}
</script>
</head>
<body>
<p>What's your favorite browser?</p>
<form>
<input type="radio" name="browser" onclick="check(this.value)" value="400mb;600mb">Internet Explorer<br>
<input type="radio" name="browser" onclick="check(this.value)" value="600mb;700mb">Firefox<br>
<input type="radio" name="browser" onclick="check(this.value)" value="500mb;500mb">Opera<br>
<input type="radio" name="browser" onclick="check(this.value)" value="500mb;500mb">Google Chrome<br>
<input type="radio" name="browser" onclick="check(this.value)" value="300mb;300mb">Safari<br>
<br>
PC Min Ram Requirement is: <input type="text" id="answer" size="20">
Mac Min Ram Requirement is: <input type="text" id="answerB" size="20">
