transport.js/run() error:'process_request' is undefined_PHP tutorial

Using ECshop’s AJAX (ie: transport.js)

Sometimes IE will appear: ReferenceError: process_request is not defined, and FF will appear: transport.js/run() error: undefined. In fact, this has nothing to do with transport.js. So what's the problem?

(1) First find lines 445-447 and find these two sentences:

/* Define two aliases */
var Ajax = Transport;
Ajax.call = Transport.run;

(2) Then I found 735 and found this sentence:

Ajax.onRunning = showLoader;

Haha... Actually the problem lies in the showLoader function in this sentence. Because there is this statement

in line 753 of this function

if (! obj && process_request), and the above problem occurs because the variable process_request is not defined! !

(3) Why is it said that the variable is not defined?

The reason is very simple, because EC often uses this sentence:

…..

Put it at the end... Of course the above error will appear when there is some other processing, JS loading, JS running, but before it reaches the bottom!!!

What is the use of the process_request variable? In fact, it is to create a DIV layer to display the message "Your request is being processed..."! ! Why is it implemented this way? Because this can support multiple languages.

Solution:

(1) Add the sentence var process_request = 'Processing your request...' in the showLoader function body; if it is in English, it will be changed to English. . .

(2) Place the sentence var process_request = "{$lang.process_request}"; in the <script> below the <header> </script>

(3) Redefine the Ajax.onRunning event. For example, you can create a new function run yourself, Ajax.onRunning = run

Second method: For this problem, the official administrator's reply is "Sometimes ajax captures incomplete order information and such an error message appears, but this will not affect your normal use, please don't worry. If you want to close , which can be removed in the basic settings of the store in the background. In fact, according to the official statement, the problem still exists. The solution is "out of sight, out of mind". Comment out this pop-up statement: Found. js/transport.js, line 227: alert(this.filename + "/run() error:" + ex.description); Copy the code and change it to: /* alert(this.filename + "/run() error:" + ex.description); */
