I updated the bookmarklet to fix some formatting issues.
```
Code:
javascript:(function() {
var textareas = document.querySelectorAll('textarea.input');
textareas.forEach(function(textarea) {
var text = textarea.value;
var pattern1 = /\[URL=(.*?)\[\/URL\]/g;
var pattern2 = /(\n)([A-Z"]|\d|\[B\]|\[I\]|\[IMG\])/g;
var pattern3 = /\[IMG alt="([^"]*)"/g;
var pattern4 = /\n/g;
var pattern5 = /(\[HEADING=2\]|\[LIST\]|\[\*\)|\[\/LIST\]|\[IMG\])/g;
var replacedText = text.replace(pattern1, '[U][URL=\$1[/URL][/U]');
replacedText = replacedText.replace(pattern2, '\$1\n\$2');
replacedText = replacedText.replace(pattern3, '\n[IMG alt="$1"');
replacedText = replacedText.replace(pattern4, '\n\n');
replacedText = replacedText.replace(pattern5, '\n\$1');
replacedText = replacedText.replace(/\n{4,}/g, '\n\n');
replacedText = replacedText.replace(/\[U\]\[U\]\[URL=(.*?)\[\/URL\]\[\/U\]\[\/U\]/g, '[U][URL=\$1[/URL][/U]');
replacedText = replacedText.replace(/\[\/HEADING\]\n/g, '[/HEADING]');
replacedText = replacedText.replace(/\[\/IMG\]\n/g, '[/IMG]');
textarea.value = replacedText;
});
})();
```
The modified bookmarklet you provided is a JavaScript code that manipulates the text content of all textarea elements with the class "input". It applies several changes to the text content of these textareas, which is stored in the
textarea.valuevariable.
Here's a breakdown of the changes you made:
1. **Pattern 3**: You've changed the pattern from
/\*)"/g to
/\[IMG alt="([^"]*)"/g. This pattern matches any text that starts with
[IMG alt=" and ends with
"]. The
([^"]*) part is a capturing group that matches any character except a double quote (`"`), repeated any number of times. The
g at the end of the pattern indicates that this pattern should be applied globally, i.e., it should match all occurrences in the string, not just the first one.
2. **Replacement for Pattern 3**: You've changed the replacement string from
'\n[IMG alt="$1"' to
'\n[IMG alt="$1"'. This means that for each match of the pattern in the text, it will be replaced with a newline character followed by
[IMG alt=", followed by the captured group (represented by
$1), and ending with
"].
Now, let's discuss what the bookmarklet does:
1. **Pattern 1**: This pattern matches any text that starts with
[URL= and ends with
[/URL]. The
([^"]*) part is a capturing group that matches any character except a double quote (`"`), repeated any number of times. The
g at the end of the pattern indicates that this pattern should be applied globally.
2. **Replacement for Pattern 1**: For each match of the pattern in the text, it is replaced with
[U][URL=$1[/URL][/U]. Here,
$1 represents the captured group in the pattern, which is the URL inside the
[URL= and
[/URL] tags.
3. **Pattern 2**: This pattern matches any newline character followed by a space, a capital letter, a double quote, or a digit, or any of the specified special tags.
4. **Replacement for Pattern 2**: For each match of the pattern in the text, it is replaced with a newline character followed by the captured group (represented by
$1), followed by another newline character.
5. **Pattern 4**: This pattern matches any newline character.
6. **Replacement for Pattern 4**: For each match of the pattern in the text, it is replaced with two newline characters.
7. **Pattern 5**: This pattern matches any of the specified special tags.
8. **Replacement for Pattern 5**: For each match of the pattern in the text, it is replaced with a newline character followed by the captured group (represented by
$1).
9. **Final Replacement**: The text is then further processed to remove any occurrence of four or more consecutive newline characters, and to remove any occurrence of
[U][U][URL= and
[/URL][/U][/U] tags.
Finally, the modified text is set as the value of the textarea. This means that the changes will be reflected in the textarea when you run the bookmarklet.
this is what it does with bbcode enabled
edit:
updated it again to fix posts with poor html formatting
This modified bookmarklet will now remove any matches for the
FONT and
COLOR tags in addition to the existing operations. The
g flag at the end of each regular expression ensures that the replace operation is performed globally, i.e., all occurrences of the pattern in the string are replaced, not just the first one
Code:
javascript:(function() {
var textareas = document.querySelectorAll('textarea.input');
textareas.forEach(function(textarea) {
var text = textarea.value;
var pattern1 = /\[URL=(.*?)\[\/URL\]/g;
var pattern2 = /(\n)([A-Z"]|\d|\[B\]|\[I\]|\[IMG\])/g;
var pattern3 = /\[IMG alt="([^"]*)"/g;
var pattern4 = /\n/g;
var pattern5 = /(\[HEADING=2\]|\[LIST\]|\[\*\)|\[\/LIST\]|\[IMG\])/g;
var pattern6 = /\[\/?FONT(=.*?)?\]/g;
var pattern7 = /\[\/?COLOR(=.*?)?\]/g;
var replacedText = text.replace(pattern1, '[U][URL=\$1[/URL][/U]');
replacedText = replacedText.replace(pattern2, '\$1\n\$2');
replacedText = replacedText.replace(pattern3, '\n[IMG alt="$1"');
replacedText = replacedText.replace(pattern4, '\n\n');
replacedText = replacedText.replace(pattern5, '\n\$1');
replacedText = replacedText.replace(pattern6, '');
replacedText = replacedText.replace(pattern7, '');
replacedText = replacedText.replace(/\n{4,}/g, '\n\n');
replacedText = replacedText.replace(/\[U\]\[U\]\[URL=(.*?)\[\/URL\]\[\/U\]\[\/U\]/g, '[U][URL=\$1[/URL][/U]');
replacedText = replacedText.replace(/\[\/HEADING\]\n/g, '[/HEADING]');
replacedText = replacedText.replace(/\[\/IMG\]\n/g, '[/IMG]');
textarea.value = replacedText;
});
})();
