在.js文件中执行PHP代码 [英] Executing PHP code inside a .js file

问题描述

我试图在.js文件中执行一些PHP，但是显然不知道如何正确执行.

I'm trying to get a bit of PHP to execute inside of a .js file, but obviously don't know how to do it properly.

基本上，代码是在页面上添加了一些HTML标记，我将这些标记用于滑出式联系表单.但是，联系表本身是在Wordpress中通过短代码完成的.因此，我试图使短代码能够在使表格滑出的代码内运行.

Basically the code is adding some HTML tags to my page, which I am using for a slideout contact form. However the contact form itself is done in Wordpress by a shortcode. So I'm trying to get the shortcode to work inside the code that makes the form slide out.

var phpTest = '<?php do_shortcode("[contact-form-7 id=\'1088\' title=\'Live Chat Form\']"); ?>';

// add feedback box
$this.html('<div id="fpi_feedback"><div id="fpi_title" class="rotate"><h2>'
    + thisSettings.title
    + '</h2></div><div id="fpi_content">'
    + phpTest
    + '</div></div>');

如果我将变量"phpTest"更改为带有文本的常规字符串，则显示效果很好，我只是不确定在这种情况下如何执行php.

If I change the variable "phpTest" to a regular string with text, it shows up fine, I'm just not sure how to execute the php in this instance.

推荐答案

编辑:脚本类型应始终为text/javascript，因为application/javascript可能会破坏与旧版浏览器的兼容性(我认为IE8和之前的版本将忽略该类型的脚本标签).但是，内容类型仍应为application/javascript.

EDIT: The script type should always be text/javascript as application/javascript may break compatibility with older browsers (I think IE8 and earlier will ignore the script tag with that type). The Content-type, however, should still be application/javascript.

您不能像普通的.php文件那样将php混入.js文件中，因为.js文件没有像.php那样由.php引擎预处理文件.

You can't mix in php into a .js file, the way you would with a normal .php file, since the .js file is not preprocessed by the .php engine the way your .php files are.

最典型的方法(包括js文件中的php)是在.php文件中仅包含内联JS(在<script>标记之间的内容).然后它将按预期工作.

The most typical way to do this--including php in a js file--is to just have inline JS (stuff between <script> tags) in your .php file. Then it will work as expected.

另一种可行的方法是在php中创建一个js文件，因此请使用以下方式启动您的.php文件

Another way to go is to make a js file within php, so start your .php file with

<?php
header("Content-type: application/javascript");
?>
var jsvar='something';
var othervar='<?php echo $phpVar; ?>';
//<?php //some php ;?>

然后像这样将其包含在您的页面中

and then include it on your page like this

<script src='myjs.php' type='text/javascript'></script>
