在JQuery中使用PHP变量

问题描述

反正我可以在JQuery脚本中使用php变量吗?

Is there anyway I can use a php variable in the JQuery script?

示例:

• PHP变量:$sr2
• JQuery脚本的摘要(带有变量):$('#a2_bottom_$sr2')

• PHP variable: $sr2
• Excerpt of JQuery script (with variable): $('#a2_bottom_$sr2')

如何使该变量在该JQuery部分中有效?

How can I make it so the variable is valid in that JQuery part?

谢谢

推荐答案

您可以简单地使用PHP回显代码以启动JavaScript变量.

What you could simply do is use your PHP to echo out the code to initiate a JavaScript variable.

<script type="text/javascript">
<?php

  $phpVar = "foo";
  echo "var phpVariable = '{$phpVar}';";

?>
</script>

一旦解析了PHP代码，并将HTML发送给用户-他们将看到的只是PHP echo的结果-

Once the PHP code is parsed, and the HTML is sent to the user - all they will see is the result of the PHP echo -

<script type="text/javascript">
  var phpVariable = 'foo';
</script>

现在您的phpVariable可用于您的JavaScript！因此，您可以像在其他任何情况下一样使用它-

Now your phpVariable is available to your JavaScript! So you use it like you would in any other case -

$("div."+phpVariable);

这将检索具有foo类的任何<div>元素-

That will retrieve us any <div> element with a foo class -

<div class="foo"></div>
