如何使用JSON转换和传输PHP变量数据到HTML页面的Javascript
[英]How to convert and transmit PHP Variable data Using JSON to HTML page's Javascript
问题描述
I can't seem to figure it out how to convert the following PHP variable to HTML: 
我似乎无法弄清楚如何将以下PHP变量转换为HTML：
$persondata = "<div id='teach'><h3>Name: " . $row["fname"]. "<br>User Name: " . $row["username"]. "</h3><p>Password: " . $row["upass"]. "</p></div><br>";
I wanted to pass that exact data to my HTML page, so that I can use JavaScript's getElementById function to insert it into a selected data field. 我想将确切的数据传递到HTML页面，以便可以使用JavaScript的getElementById函数将其插入到选定的数据字段中。
I asked a similar question here , which helped me work out some of logic I need, but I can't work out this part of the equation. 我在这里提出了类似的问题，该问题帮助我确定了所需的一些逻辑，但我无法解决等式的这一部分。
If you could please let me know of a simple way of going about this, it would be very much appreciated, as I don't even know the keywords to search for. 如果可以的话，请让我知道一种简单的处理方法，将不胜感激，因为我什至不知道要搜索的关键字。

A javaScriptVar equals with an echo in php of your php variable. 一个javaScriptVar等于您的php变量在php中的回显。
That is to put php inside js 那就是将php放入js
<script type="text/javascript">
//Your JS
var jsvar = <?php echo $persondata; ?>
//Your JS
</script>
Put PHP var like above into js. 将上面的PHP var放入js。

Continuing from above answer: 从上述答案继续：
That is to put php inside js 那就是将php放入js
<script type="text/javascript">
//Your JS
var jsvar = <?php echo $persondata; ?>;
//Your JS
</script>
Put PHP var like above into js. 将上面的PHP var放入js。
If you want to transmit data from a PHP script in a server to a client side HTML page for using in js. 如果要将数据从服务器中的PHP脚本传输到客户端HTML页面以在js中使用。 Go like following. 像下面一样去。
- First get all your data in PHP in an array and use
json_encode()and after thatechothat variable.首先在数组中使用PHP获取所有数据，然后使用json_encode()，然后echo该变量。 - Now in the client side HTML use
jQuery.ajax()and send request to that PHP file in server.现在在客户端HTML中使用jQuery.ajax()并将请求发送到服务器中的该PHP文件。 - When you have the response in Json use js to fragment it and append wherever you want. 当您在Json中获得响应时，请使用js对其进行分段，然后将其附加到所需的任何位置。
Above is the basic procedure to send data from PHP to HTML page using JS. 上面是使用JS将数据从PHP发送到HTML页面的基本过程。
