将JavaScript变量从CakePHP视图传递到控制器

Question

I'm new to CakePHP and plan on developing an application with it. I was wondering if there is a way to pass JavaScript variables created in a View to it's corresponding Controller?

For example, if I generated two coordinate variables using the HTML5 Geolocation JavaScript API in a View, how could I pass these JS variables to a corresponding Controller in order to use them to query a database in a function?

Thanks for the help!

Answer 1

Use AJAX Make a request to that controller action and send those values. The controller should send back a response that you can use in javascript

Answer 2

You can:

• Use AJAX
• Use JavaScript to submit a form
• Use JavaScript to redirect to a URL with ?get variables

Answer 3

Use Ajax and send javascript values as query string in your URL.

In controller, you can get those values using PHP way $_Get['name'] or using cake way $this->request->query['variable_name'];

Hope it helps.

Answer 4

基本上，您需要以任何您喜欢的方式将数据发送到控制器。
