我有值A和C，如何使用javascript检查A和C

Answer 1

这应该适合您。

var myNodeList = document.querySelectorAll("input[value=A], input[value=C]");
for (i = 0; i <	myNodeList.length; i++) {
   	myNodeList[i].checked = true;
}

<input type="checkbox" name="name[]" value="A">A</input>
<input type="checkbox" name="name[]" value="C">C</input>
<input type="checkbox" name="name[]" value="D">D</input>
<input type="checkbox" name="name[]" value="E">E</input>
