通過POST將JavaScript變量發送到PHP

Question

是否可以在提交表單時將JavaScript變量的內容發送給PHP？

Answer 1

是。 只需在表單提交事件中添加一個javascript回調即可

<script type="text/javascript">
    var myglobalvariable = "myvalue";
    onSubmit = function(){
        document.myform.myinput.value = myglobalvariable;  return true;
    }
</script>
<form name="myform" id="myform" method="post" action="index.php" onsubmit="onSubmit();">
    <input name="myinput" id="myinput" type="hidden" />
</form>
