show dialog for option submit data -


I have a submission form. I want to show a jquery dialog when someone submits the same data "This data first Exists from! Are you sure about input? " Then select OK or Cancel Can you please tell me what should I do? Thank you.

Send an AJAX request with data from the server - with it, and if the data is present then any The type of error code is returned. Then check for error in AJAX handler, if it is present then "data added" will not show the message to show the message "already exists". The server-side should check the duplicate, as well as enter new data as well.

If the user selects "OK" in the "Data Exists" dialog, then send another request with the parameter to prevent duplicate error.

> Customers: 

  $ Post ("server.php", {"data": somedata}, function (result) {if (result.error & amp; result.error == 1) if (confirm ("duplicate data, continue? ") $ .post (" server.php, {"data": somedata, "suppress": 1}, function (result) {warning ("data was added");); other warning ("data added

Server: Data ']) and $ _POST [' data '] = "") {if (check _duplicate ($ _ POST [' data ']) // this & amp; Do not forget to apply $ _POST ['press']!] = 1) return' {"error": 1} '; else {insert_data ($ _ POST [' data ']); return' {OK } '; // You can also return empty string properly}}

I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
