Problem with using Views Ajax for PAGER in the block

Add the function of Drupal.Views.Ajax.handleErrors /sites/all/modules/views/ajax.js in (modules_dir) /sites/all/modules/views/ajax_view.js. But will still be some error (alert error), he is now corrected with this error)))

not what I wanted to write or can translate.google.com))
In the file/sites/all/modules/views/js/ajax_view.js Drupal.Views.Ajax.handleErrors add function from the file/sites/all/modules/views/js/ajax.js (at the bottom somewhere).
Further problem with the encode json:
should be replaced by a function drupal_to_js (common.php)
line 2499

return '"'. str_replace(array("\r", "\n", "<", ">", "&"),
                              array('\r', '\n', '\x3c', '\x3e', '\x26'),
                              addslashes($var)) .'"';

to a new

$replace_pairs = array(
        // ", \ and U+0000 - U+001F must be escaped according to RFC 4627.

I picked up from the last patch d7.
And you can string 2536 (drupal_set_header ('Content-Type: text / javascript; charset = utf-8')) is replaced by drupal_set_header ('Content-Type: application / json;');
Bear in mind you change in the core CMS))

Мне за что))

Here is a patch to fix a problem in ajax_view.js (no function Drupal.Views.Ajax.handleErrors).
But does not solve the problem of parsing json function drupal_to_js

I had the same problem and this solution helped.

Thanks!

+  else if(textStatus=='timeout'){
+      error_text = Drupal.t("The server doesn't answer. Time out.");
+  }
+  else if(textStatus=='parsererror') {
+      error_text = Drupal.t("Error while parsing code");
+  }
+  else {
+    error_text = xhr.status + ': ' + xhr.statusText;
+  }

Could you use drupal code style? Thanks!

Won't it be simpler to just include the ajax.js file too? Am I missing something?

I had similar symptoms. Though the button would work on the second click. A 302 redirect was being called by Secure Pages module... which then threw an error and caused views to call the non-existent function.

The ajax path being used by views was not properly whitelisted in Secure Pages configuration. Adding "views/ajax*" to the whitelist section resolved the issue for me. Hope this helps someone.

related to #3, i found i was getting this problem because of U+2028 characters in pasted text. the code in #3 prevents the json ajax error from Views, but it still failed - i had to replace those characters with blanks. see #479368: D7: Create RFC compliant HTML safe JSON

i had the same issue but the above solution fixed my issue Thank you kratkar

Steps i have followed
1) Added the function Drupal.Views.Ajax.handleErrors to /modules/view/js/ajax_view.js
/**
* Display error in a more fashion way
*/
Drupal.Views.Ajax.handleErrors = function (xhr, path) {
var error_text = '';

if ((xhr.status == 500 && xhr.responseText) || xhr.status == 200) {
error_text = xhr.responseText;

// Replace all < and > by < and >
error_text = error_text.replace("/&(lt|gt);/g", function (m, p) {
return (p == "lt")? "<" : ">";
});

// Now, replace all html tags by empty spaces
error_text = error_text.replace(/<("[^"]*"|'[^']*'|[^'">])*>/gi,"");

// Fix end lines
error_text = error_text.replace(/[\n]+\s+/g,"\n");
}
else if (xhr.status == 500) {
error_text = xhr.status + ': ' + Drupal.t("Internal server error. Please see server or PHP logs for error information.");
}
else {
error_text = xhr.status + ': ' + xhr.statusText;
}

alert(Drupal.t("An error occurred at @path.\n\nError Description: @error", {'@path': path, '@error': error_text}));
}

2) Changed the below line in /includes/common.js inside the function drupal_to_js
return '"'. str_replace(array("\r", "\n", "<", ">", "&"),
array('\r', '\n', '\x3c', '\x3e', '\x26'),
addslashes($var)) .'"';

to

$replace_pairs = array(
// ", \ and U+0000 - U+001F must be escaped according to RFC 4627.
'\\' => '\u005c',
'"' => '\u0022',
"\x00" => '\u0000',
"\x01" => '\u0001',
"\x02" => '\u0002',
"\x03" => '\u0003',
"\x04" => '\u0004',
"\x05" => '\u0005',
"\x06" => '\u0006',
"\x07" => '\u0007',
"\x08" => '\u0008',
"\x09" => '\u0009',

"\x0d" => '\u000d',

"\x10" => '\u0010',
"\x11" => '\u0011',
"\x12" => '\u0012',
"\x13" => '\u0013',
"\x14" => '\u0014',

"\x17" => '\u0017',
"\x18" => '\u0018',
"\x19" => '\u0019',
"\x1a" => '\u001a',
"\x1b" => '\u001b',
"\x1c" => '\u001c',
"\x1d" => '\u001d',
"\x1e" => '\u001e',
"\x1f" => '\u001f',
// Prevent browsers from interpreting these as as special.
"'" => '\u0027',
'<' => '\u003c',
'>' => '\u003e',
'&' => '\u0026',
// Prevent browsers from interpreting the solidus as special and
// non-compliant JSON parsers from interpreting // as a comment.
'/' => '\u002f',
// While these are allowed unescaped according to ECMA-262, section
// 15.12.2, they cause problems in some JSON parser.
"\xe2\x80\xa8" => '\u2028', // U+2028, Line Separator.
"\xe2\x80\xa9" => '\u2029', // U+2029, Paragraph Separator.
);

return '"'. strtr($var, $replace_pairs) .'"';

Thanks a lot jp_rajan!

Fixed my issue!

thanks @jp_rajanfor - I had the same issue with views 6.x-2.12 and your solution fixed it. Can you submit a patch or shall I?

is this function present in the D7 version?

Works for me, aside from the fact that core still doesn't contain the patch mentioned in #1086098: D6 JSON is total garbage - Create RFC 4627 compliant HTML safe JSON which is a related to the issue, but can't be part of this issue's resolution really.

Marking this as critical since it exists in a stable release of views 6.x-3.0 and it breaks the normal operation of the ajax pager.

Hi

I had the same symptoms.
I also found out that this is related to certain characters, as described in #15.

The instructions in #16 solved the problem.
Thank you!

Is there a way to prevent the storing of problematic characters in the first place?
With transliteration or the ckeditor module?

I'm using the Secure Pages module and was facing the same problem. wwwpro's solution in #14 fixed it!

On Drupal 6.19, got this error after upgrading jQuery from version 1.3.2 to 1.7.1.
Found out that the bug was with drupal_json function under include/common.inc. Solution #3 fixed it. Thanks to kratkar.
Note that the drupal_set_header('Content-Type: text/javascript; charset=utf-8'); is commented only, notifying the client that the returned content is of json type is not necessary in my case.

Solution #3 fixed it. Thanks to kratkar.
