我目前正在使用复选框并根据所选值显示值。几乎所有东西都在我必须选中复选框的异常情况下工作method of shipping
。现在用户可以选择两种方式,这是一个问题。有没有办法只允许检查一个复选框method of shipping
?例子
JS
<script>
function check_value(currentElement, val, id, type) {
var el = document.getElementById("imgBox" + id);
if (val > 0 && val < 4) { //will trigger when [1,2,3]
if(currentElement.checked)
{
el.src = "images/" + type + val + ".jpg";
el.style.display = "";
}
else
{
el.src = "";
el.style.display = "none";
}
}
}
</script>
HTML
<h2>Choose method of shipping</h2>
<form name="shipping_list">
<input type="checkbox" name="shipping1" onclick='check_value(this, 1, "4", "shipping")'/> USPS Ground<br />
<input type="checkbox" name="shipping2" onclick='check_value(this, 2, "4", "shipping")'/> FedEx
</form>
<img id="imgBox4" src="#" style="display:none">
