将 JavaScript 变量传递给嵌入在 php 中的 html 时遇到问题

Question

as my title indicates, I am having trouble passing a JavaScript variable to html that is embedded in PHP. The PHP (html, JavaScript) file works and display's a document on the browser. Where I need help is in calling a JavaScript function from the embedded html. As the document is being is being constructed, that's when the JavaScript function should be called so that the document will contain the retrieved JavaScript value. I have tried various solutions, but they do not work. I hope my explanation is not too wordy. If you need to see code, please let me know

Answer 1

Unfortunately, I don't think it's going to work the way you hope. The PHP is being run server side, before it is sent to the client. The end user is downloading the constructed html before his or her browser ever starts running the javascript.

Answer 2

You are trying (by the sounds of it) to run PHP and Javascript at the same time to populate your tags... This isn't going to work.

Three Options:

• Do everything in PHP on the server and send the completed page. (most logical)
• Do what you can in PHP, send the page to the client and execute an AJAX call on page load to finish the job. (if javascript is needed)
• Use Node... (Javascript that runs on the server - it's a win / win situation)
