将变量从一个HTML页面传递到另一个HTML页面的最佳做法是什么？ [英] What is the best practice for passing variables from one HTML page to another?
问题描述
我对网络应用程序编程相对较新，所以我希望这个问题对于每个人来说都不是太基础。
I'm relatively new to web application programming so I hope this question isn't too basic for everyone.
我创建了一个带有FORM的HTML页面，该页面包含一个dojox datagrid（v1.2），填充了不同杂货项目的描述行。用户选择他感兴趣的项目后，他将点击提交按钮。
I created a HTML page with a FORM containing a dojox datagrid (v1.2) filled with rows of descriptions for different grocery items. After the user selects the item he's interested in, he will click on the "Submit" button.
在这一点上，我可以得到javascript函数将项目ID号存储为javascript变量但是我不知道如何将此ID传递到后续的HTML
At this point, I can get the javascript function to store the item ID number as a javascript variable BUT I don't know how to pass this ID onto the subsequent HTML page.
我应该将ID作为URL查询字符串参数传递吗？还有其他更好的方法吗？
Should I just pass the ID as an URL query string parameter? Are there any other better ways?
编辑：整个过程就像一个购物车。用户将从网格中选择项目，然后在下一页用户将填写一些详细信息，然后结帐。
The overall process is like a shopping cart. The user will select the item from the grid and then on the next page the user will fill out some details and then checkout.
我还应该提到我正在使用grails，所以这是发生在一个GSP页面，但目前它只包含HTML。
I should also mention that I'm using grails so this is happening in a GSP page but currently it only contains HTML.
推荐答案
你可以使用隐藏的输入字段;作为表单的一部分发送。
You could just use a hidden input field; that gets transmitted as part of the form.
<html>
<head>
</head>
<body>
<script type="text/javascript">
function updateSelectedItemId() {
document.myForm.selectedItemId.value = 2;
alert(document.myForm.selectedItemId.value);
// For you this would place the selected item id in the hidden
// field in stead of 2, and submit the form in stead of alert
}
</script>
Your grid comes here; it need not be in the form
<form name="myForm">
<input type="hidden" name="selectedItemId" value="XXX">
The submit button must be in the form.
<input type="button" value="changeSelectedItem" onClick="updateSelectedItemId()">
</form>
</body>
</html>
