如何在Js按钮单击时使用Javascript变量执行PHP脚本? [关闭]
I would like to run a PHP segment of code with veriables from a Javascript text field while using that veriable in the PHP function. All of that should be executed with a Javascript button click.
[Js Text] --> Js button click --> veriable --> PHP (MySQL DB)
An attached sample code would be grand.
Thanks.
KEYWORD: AJAX (Asynchronous JavaScript and XML).
With jQuery you can perform a POST
request to a PHP script and receive a response.
$.post("test.php", { name: "John", time: "2pm" })
.done(function(data) {
alert("Data Loaded: " + data);
});
See: http://api.jquery.com/jQuery.post/
PS:
In your PHP you can use: $_POST['name']
/$_POST['time']
to request these variables.
use ajax...if you are using jquery check http://api.jquery.com/jQuery.ajax/ and for running the ajax event look for the click event @ http://api.jquery.com/click/
As far as I know, there's no way to execute php by js, because the process of interpreting a php webpage is as follows:
php server ==generate==> html files ==webbrowser execute==> JS
You just cannot go back to the first stage in js. Also the js is executed at your browser rather than the server.
To do your work, you should write a new php page that execute the desired action and call this page using JS.
Also, I assume you are just calling Database, and you can definately find other ways to link to database via JS.
