我想有可能与javascript取消选择复选框"demo2"当我取消选中复选框"demo1"。只有取消选择
<input type="checkbox" name="demo1" value="Bike">
<label for="vehicle1"> I have a bike</label><br>
<input type="checkbox" name="demo2" value="Car">
<label for="vehicle2"> I have a car</label><br>
我猜你只是想用" radio";这样的行为。你可以在下面看到如何使用纯JS完成它。
<html>
<body>
<script>
function switcher(obj) {
if(obj.checked == true) {
document.getElementsByName('demo2')[0].checked = false;
document.getElementsByName('demo1')[0].checked = false;
obj.checked= true
}
}
</script>
<input type="checkbox" name="demo1" value="Bike" onclick="switcher(this)">
<label for="vehicle1"> I have a bike</label><br>
<input type="checkbox" name="demo2" value="Car" onclick="switcher(this)">
<label for="vehicle2"> I have a car</label><br>
</body>
</html>
