如何在PHPFox中通过Ajax获取任何DOM元素 [英] How to get any DOM Element by Ajax in PHPFox

问题描述

我认为我可以使用

$this->get('element_id')

获取Ajax函数中每个DOM元素的值.但这是行不通的.只有Post-Elements我可以这样，对吗? 但是我如何获得其他元素?

to get the value of each DOM-Element in a Ajax-Function. But that doesn't work. Only Post-Elements i can get this way, right? But how do i get other Elements?

感谢您的帮助...

这是我的Ajax级:

class Name_Component_Ajax_Folder_Ajax extends Phpfox_Ajax
{
public function test(){

    $iChildItemId = $this->get('element_id');
    var_dump($iChildItemId);
    $this->html('#testdiv', $this->getContent());
}
}

通过单击链接，我调用此函数(test())，我想获取输入字段的值(elemnt_id)

By clicking a link i call this function ( test() ) and i want to get the value of an input-field (elemnt_id)

推荐答案

基本上，您有2种常见的解决方案来在Web浏览器(Firefox，Chrome等)发送给服务器的AJAX请求中传递值.

Basically, you have 2 common solutions to pass a value in an AJAX request that Web browse (Firefox, Chrome, ...) sends to server.

如果使用的是POST请求，则应将期望值指定为隐藏输入<input type='hidden' id='val1' value='value_you_want_to_pass_to_sever'>.

If you are using POST request, you should specific your expected value as a hidden input <input type='hidden' id='val1' value='value_you_want_to_pass_to_sever'>.

如果使用的是GET请求，则可以使用URL参数传递该请求，例如:www.youserver.com?val1=value_you_want_to_pass.

If you are using GET request, you can pass it by using URL param for ex: www.youserver.com?val1=value_you_want_to_pass.

您可以使用JQuery获得要传递的价值.

You can get value you want to pass by using JQuery.

然后，您可以使用$ this-> get('val1')在服务器端获取价值.

Then you can use $this->get('val1') to get your value at server side.
