Textarea类型特殊字符

Question

In a textarea I want the user to be able to press the letters on their keyboard and type 𝒜ℬ𝒞𝒟 etc. (so typing the &ascr ; &bscr ; special characters)

Is there anyway to do this? And have the user freely being able to edit the characters like in a normal textarea.

The user will be able to click to select a style (which sets my var style integer) and the letters will be a different style like 𝔄𝔅ℭ𝔇 (&Afr ; &Bfr ; &Cfr ; etc.)

What I want to achieve at the end is the user typing a paragraph, then the text will appear formatted in that way in the textarea, they could switch styles in between. Then they will be able to copy the text / save it as a .html file.

Any method is welcome! :)

Thanks!

Example of what the user could type: Hello my name is Friedpanseller!

What the textarea could display: ℋℯ𝓁𝓁ℴ ℳ𝓎 𝒩𝒶𝓂ℯ ℐ𝓈 𝔉𝔯𝔦𝔢𝔡𝔭𝔞𝔫𝔰𝔢𝔩𝔩𝔢𝔯!

Then the user can delete some words in the middle / edit them like a normal textarea

尝试使用第三方工具（我更喜欢使用CKEditor ），因为它是免费的

Here is an example of what you could do. Type "a" (without quotes) into that text area. It's not exactly fast , but it's what I could gather. It doesn't address all of your requests but it's a start.

$("textarea").bind("keyup", function() {
    var cursorPosition = $('textarea').prop("selectionStart");
    var text = $(this).val();
    if (text.indexOf('a') > -1) {
        text = text.replace(/a/g, '𝒶');
        $(this).val(text);
        $('textarea').prop("selectionStart", cursorPosition - 1);
        $('textarea').prop("selectionEnd", cursorPosition - 1);
    }
});

You could try to apply this systematically for the characters you want to substitute. Good luck.

When you are adding the code in blank html, please add document.ready for jquery event bind.

$(document).ready(function(){
$("textarea").bind("keyup", function() {
    var cursorPosition = $('textarea').prop("selectionStart");
    var text = $(this).val();
    if (text.indexOf('a') > -1) {
        text = text.replace(/a/g, '𝒶');
        $(this).val(text);
        $('textarea').prop("selectionStart", cursorPosition - 1);
        $('textarea').prop("selectionEnd", cursorPosition - 1);
    }
});
});

It works this way, if we use the same code in separate HTML page.
