javascript - 如何在单击复选框时使用数据库中的值填充输入文本字段

Question

我正在尝试使用单击复选框事件时从 SELECT 查询返回的变量值自动填充多个输入文本字段。例如:SELECT 查询返回 Warehouse Street Address ($WarehouseStreetAdress)。然后在选中“使用仓库街道地址”复选框后，应将该地址输入到输入文本字段中。我有以下代码:

$WarehouseStreetAddress = $_POST['WarehouseStreetAddress']; ...Select query works fine...

<input id="checkbox" type="checkbox"> Use Warehouse Address<br>
Street Address: <input id="StreetAddress" type="text"> 

$("#checkbox").change(function() {
    if (this.checked) {
    var StreetAddress= $WarehouseStreetAdress;
    }
$("#StreetAddress").val(StreetAddress);
}

Answer 1

我认为您混合了 PHP 和 Javascript..

<input id="checkbox" type="checkbox"> Use Warehouse Address<br>
Street Address: <input id="StreetAddress" type="text"> 

<script type="text/javascript">
$("#checkbox").change(function() {
    if (this.checked) {
        $("#StreetAddress").val("<?php echo $_POST['WarehouseStreetAddress'];?>");
    }
})
</script>
