如何在第二页上将值从Javascript传递给php变量？
[英]How to pass value from Javascript to php variable on the second page?
问题描述
I have two pages. 
我有两页。 One that accepts input and stores it to a javascript variable. 接受输入并将其存储到javascript变量的接收器。 The other will receive the sent variable and store it to php variable so that i can forward it to the database. 另一个将接收发送的变量并将其存储到php变量，以便我可以将其转发到数据库。
here's the code of my first page: 这是我的第一页的代码：
<html>
<head>
<script type="text/javascript">
var pricee= 0;
var quants;
function queue(num,str){
this.pricee=num;
this.quants=str;
alert(num+" "+str);
}
function alertCurrentNumandStr(){
alert("This is the latest: "+this.pricee+" "+this.quants);
}
function send(num){
this.pricee=num;
}
</script>
</head>
<body>
<ul>
<li><script type="text/javascript">var x=42, y="alive";</script><a href="#" onclick="queue(x, y);">42 Alive</a></li>
<li><a href="#" onclick="alertCurrentNumandStr();">Get</a></li>
<li><script type="text/javascript">var t=10;</script><a href="#" onclick="send(t);">Submit</a></li>
<!--How to send this.pricee, this.quants to .php when clicking the Submit link(above)?-->
</ul>
</body>
</html>
And code on my secondpage: 和我的第二页上的代码：
<html>
<head>
<?php
$testNum= $_GET['pricee']
?>
</head>
<body>
<?php
echo "<h1>The num value </h1>";
echo $testNum;
?>
</body>
</html>
How can I pass the javascript variables to the second page when I click Submit? 单击“提交”后，如何将javascript变量传递到第二页？

You can also do this with simple GET Variable. 您也可以使用简单的GET变量执行此操作。
-
<a href='yourphpfilename.php?price1=xxx&YOUR2ndvariable=xxx'>Click this</a> And by forwarding to the next php page, simple fetch this variables using
通过转发到下一个php页面，使用简单的获取此变量 $_GET['price1'];
$ _GET [ '价格1']; ... ...

change your send function to this 将您的发送功能更改为此
function send(quants){
window.location.href = "yourPhpPageUrl.com?price"+pricee+'qunatity' +quants;
}
there will be no change in your PHP file . 你的PHP file没有变化。 just give it a try 试一试吧

put your li tags in form tag like so: 把你的li标签放在form标签中，如下所示：
<form action="action_page.php" method="GET">
<ul>
<li><script type="text/javascript">var price1=12, itn1="Mar";</script><a href="#" onclick="queue(price1, itn1);">Marinated $12</a></li>
<li><script type="text/javascript">var price2=1, itn2="Kalamay";</script><a href="#" onclick="queue(price2, itn2);">Kalamay $1</a></li>
<li><script type="text/javascript">var price3=5, itn3="coach Yeng";</script><a href="#" onclick="queue(price3, itn3);">Coach Yeng $5</a></li>
<li><a href="#" onclick="getPrice();">Get</a></li>
<li><script type="text/javascript">var quantity=10;</script><a href="#" onclick="send(quantity);">Submit</a></li>
</ul>
<input type="text" name="pricee" value="100">
<br>
Pricee:<br>
<input type="submit" value="Submit">
</form>
i have assumed here that your php page is action_page.php 我假设你的php页面是action_page.php
here method = "GET" tells the php page tha it has to receive the values as get requests. 这里method = "GET"告诉php页面它必须接收值为get request。
In addition to this, input type="submit" before the closing form tag tells that you are using a submit event to sent the values in the li tags. 除此之外，在结束form标记之前input type="submit"表示您正在使用submit事件来发送li标记中的值。
You have used a pricee tag in your php code ( $_GET("pricee") ). 您在PHP代码中使用了pricee标签（ $_GET("pricee") ）。 To match this request you must have an element with name="pricee" . 要匹配此请求，您必须拥有name="pricee"的元素。
I have added that tag above. 我在上面添加了这个标签。
