我有这个隐藏的div
<div class="amount" style="display:none;">$30.00</div>
我用Javascript获得这个div值:
var price;
window.onload = function(){
//Get the value from the amount div
price = document.getElementsByClassName('amount')[0].innerHTML;
//Set the hidden_price input value (on the form below) to the price
document.getElementById("hidden_price").value = price;
};
现在我有一个隐藏输入的表单
<form action="phpfile.php" method="post">
<input type="hidden" name="hidden_price" id="hidden_price">
<input type="submit" />
</form>
当我点击提交时,我在php中有变量
$hidden_price = $_POST['hidden_price'];
我可以不提交表格吗?
答案 0 :(得分:0)
提交表单的等效表单可以是:
$.post('phpfile.php', $("form").serialize(), .done(function( data ) { alert( "Data Loaded: " + data ); });
