php - CodeIgniter error pages show in popup mode -

-

How can we display all kinds of error messages without redirecting error pages application \ errors \ * Error_pages *
Here, we will be in the same page and if any error occurs on the action, it will appear in popup mode. Can anyone help me with code example?

Although the question is not clear, you can check the availability of a 404-Not Found page like this. : -

The first open routes in the App / Config folder Set php and a custom controller name. 

  $ route ['404_override'] = 'my404 / 404_page'; // is the name of my404 class.

Create a new administrator and type the following code into it. 

  & lt ;? Php class my404 CI_Controller {public function __construct () {parent:: __ generation (); } Public Function 404_page () {// Instead of loading any view, simply handle this response via AJAX call from your client side $ error = array (); $ Error ['ERROR_CODE'] = '404'; $ Error ['error_message'] = 'This URL was not found'; Echo json_encode ($ error); }}? & Gt;

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
