Re: help clicking radio buttons using WWW::Mechanize::Chrome

I can't reproduce the problem. I'm using WWW::Mechanize::Chrome v0.65, Chromium v87, and the following program:

#!/usr/bin/perl -w
use strict;
use 5.012;
use Log::Log4perl qw(:easy);
use WWW::Mechanize::Chrome;

my $url = "https://www.tenthousand.cc/products/interval-short";

Log::Log4perl->easy_init($ERROR);
my $mech = WWW::Mechanize::Chrome->new(
    #headless => 0,
    # headless => 1,
    # launch_exe => 'C:\Program Files (x86)\Google\Chrome\Application\
+chrome.exe'
);
my $post_response;

$post_response = $mech->get($url);
$post_response->is_success || die $post_response->status_line;

$mech->sleep(5);

# step 1 - select color
say "Color";
$mech->click({id => 'ProductSelect-option-color-solar-8568844557'});

# step 2 - select size
say "Size";
$mech->click({id => 'ProductSelect-option-size-medium-8568844557'});

# step 3 - select inseam
say "Inseam";
$mech->click({id => 'ProductSelect-option-inseam-9-inch-8568844557'});

# step 4 - select liner/no liner
say "Liner";
$mech->click({id => 'ProductSelect-option-liner-no-8568844557'});
say "Done";
$mech->sleep(5);

This program runs through to Done, waits 5 seconds and then finished. It seems to me all elements on the website get selected.

Maybe you are using an older version of WWW::Mechanize::Chrome?

After further testing I verified the following: 1. I am using WWW-Mechanize-Chrome-0.65 2. I am using Chrome 87.0.4280.141 (Official Build) (64-bit) 3. Adding the `$mech->sleep(5);` after the `$post_response->is_success \|\| die $post_response->status_line;` as you have done above fixed my problem. Is this `sleep()` call always necessary after a `get()` due to the following (taken from the documentation): Note that the returned HTTP::Response object gets the response body filled in lazily, so you might have to wait a moment to get the response body from the result. This is a premature optimization and later releases of WWW::Mechanize::Chrome are planned to fetch the response body immediately when accessing the response body. Finally, I noticed that if I change this line: `$mech->click({id => 'ProductSelect-option-color-solar-8568844557'});` [download] to the following: `my $response = $mech->click({id => 'ProductSelect-option-color-solar-8 +568844557'}); $mech->sleep(5); print Dumper($response); if ($response->is_success) { printf("click succeeded\n"); }` [download] the output is: `> ./www_mechanize_chrome_testcase.pl $VAR1 = []; Can't call method "is_success" on unblessed reference at ./www_mechani +ze_chrome_testcase.pl line 27.` [download] Is that expected? If `$mech->click()` returns an `HTTP::Response` object, shouldn't I be able to call the `is_success` method?	[reply] [d/l] [select]

Ouch - yes, that is an inconsistency/bug in the behaviour of `->click()`. When the `->click()` method results in external HTTP requests, then the returned value is an HTTP::Response object. When the result is just some internal Javascript code, the result is an arrayref of the triggered events. This is wrong and I'll make it so that `->click` always returns an HTTP::Response object, as documented.	[reply] [d/l] [select]

I noticed that adding the following line from your example fixed my code: `$mech->sleep(5);` [download] Generally speaking, should one always call `$mech->sleep();` after a call to `$mech->get()` (and possibly other methods)? I didn't see this explicitly mentioned in the documentation for the `get()` method but I'm not a web developer so maybe it's just common knowledge that something like that is required?
