laravel 4: URL::route vs jquery
提问by user2482384
(As new laravel user) I'm trying to build a ajax call url through the laravel URL::class:
（作为新的 Laravel 用户）我正在尝试通过 Laravel URL::class 构建一个 ajax 调用 url：
$.ajax( {
url: '{{ URL::route('getUser', ['3']) }}',
success: function(results) {
alert(results);
}
});
routes.php:
路线.php：
Route::get('admin/getUser/{user_id}', array(
'as' => 'getUser',
'uses' => 'AdminController@getUser'
));
Instead of the hard coded 3this parameter should come from jquery (e.g. $(this).attr('user_id')).
3这个参数应该来自jquery（例如$(this).attr('user_id')）而不是硬编码。
Can someone tell me how to create the URL dynamically?
有人能告诉我如何动态创建 URL 吗？
It seems that because of the route definition the URL::routefunction needs the parameter hardcoded or as a php varaible.
似乎由于路由定义，URL::route函数需要硬编码参数或作为 php 变量。
I hope this is +/- clear...
我希望这是 +/- 清楚...
Thanks for help anyway!
无论如何感谢您的帮助！

You could keep the url clean and pass the variable as data in your ajax call.
您可以保持 url 干净并在 ajax 调用中将变量作为数据传递。
var urlGetUser = "{{ URL::route('getUser') }}",
userId = $(this).attr('user_id');
$.ajax({
type: "POST",
url: urlGetUser,
data: { id: userId }
}).done(function( msg ) {
alert( msg );
});
This way you won't have to create ajax calls for every possible user ID. Something both other current solutions also offer.
这样您就不必为每个可能的用户 ID 创建 ajax 调用。其他当前的解决方案也提供了一些东西。

I've been using URL::to() for my Ajax calls. I've had problems to. But if you do use URL::to() you would be able to use javascript variables. try this:
我一直在使用 URL::to() 进行 Ajax 调用。我遇到了问题。但是，如果您确实使用 URL::to()，您将能够使用 javascript 变量。尝试这个：
$id = 3;
"{{URL::to('getUser/'".$id.")}}"
Hope this helps, I'm new too. if you find a better way to do this awesome, let me know ;)
希望这有帮助，我也是新手。如果您找到更好的方法来做到这一点，请告诉我；）

Because PHP actually handles the file before passing it to the browser it may be indeed impossible to dynamically use a php variable directly, but theres a way around it. This may work ONLY if you havent type-casted your route parameter user_idto a certain definition.
因为 PHP 在将文件传递给浏览器之前实际上会对其进行处理，所以直接动态地使用 php 变量确实是不可能的，但是有一种方法可以解决它。仅当您没有将路由参数类型user_id转换为某个定义时，这才可能起作用。
// Add a placeholder which we'll use jQuery to swap out later
urlTo = "{{ URL::route('getUser', ['%userid%']) }}";
// swap out the placeholder dynamically using jQuery
urlTo = urlTo.replace('%userid%', $('#someElement').attr('user_id'));
$.ajax({
url: urlTo,
success: function(results) {
alert(results);
}
});
What we've done here is to create a placeholder in our URL generated from a route so we'll probably have a URL like http://localhost/app/profile/%userid%after PHP has finished processing. We then use jQuery to replace the placeholder to our actual dynamic value.
我们在这里所做的是在从路由生成的 URL 中创建一个占位符，因此我们可能会http://localhost/app/profile/%userid%在 PHP 完成处理后得到一个 URL 。然后我们使用 jQuery 将占位符替换为我们的实际动态值。
