如何保持textarea中的文本格式相同

Question

I am inserting some text using textarea. I want to substring the textarea once it reaches the limit and set the content to the same editor. But its removing the formatting before whatever is texted and setting plain text. I want with same format.

  tinyMCE.init({ mode: "textareas", theme: "advanced", editor_selector: "mceEditor", paste_auto_cleanup_on_paste: 'true', theme_advanced_disable: 'justifyleft,justifyright,justifyfull,justifycenter,indent,image,anchor,sub,sup,unlink,outdent,help,removeformat,link,fontselect,hr,styleselect,formatselect,charmap,separator,code,visualaid,strikethrough,fullscreen', theme_advanced_buttons1: 'bold,italic,underline,numlist,bullist,undo,redo,cleanup,spellchecker', theme_advanced_buttons2: "", theme_advanced_buttons3: "", plugins: 'spellchecker,fullscreen,paste', spellchecker_languages: '+English=en-us', spellchecker_rpc_url: '<%out.print(request.getContextPath());%>/jazzy-spellchecker', theme_advanced_statusbar_location: "bottom", theme_advanced_path: false, statusbar: true, setup: function (editor) { editor.onKeyUp.add(function (evt) { var inputRichTextArea = $(editor.getBody()).text(); var maxLengthRichTextArea = document.getElementById(editor.id).maxLength; var inputRichTextAreaLength = inputRichTextArea.length; if (inputRichTextAreaLength > maxLengthRichTextArea) { inputRichTextAreaLength = maxLengthRichTextArea; editor.setContent(""); tinyMCE.activeEditor.selection.setContent(inputRichTextArea.substring(0, maxLengthRichTextArea)); } var value = maxLengthRichTextArea - inputRichTextAreaLength; if (value >= 0) { $(editor.getContainer()).find("#" + editor.id + "_path_row").html("Remaining characters: " + (value)); } if (inputRichTextAreaLength >= maxLengthRichTextArea) { $(editor.getBody()).keypress(function (e) { inputRichTextAreaLength = $(editor.getBody()).text().length; if (inputRichTextAreaLength >= maxLengthRichTextArea) { e.stopPropagation(); return false; } var value = maxLengthRichTextArea - inputRichTextAreaLength; if (value >= 0) { $(tinyMCE.activeEditor.getContainer()).find("#" + editor.id + "_path_row").html("Remaining characters: " + (value)); } }); } }); } }); 

 <textarea maxlength = 50 rows="4" cols="50"></textarea 

How can I keep the same formatting.

Pasting text

Formatting text

In your example, you use the function .text() to get the content which only selects the text without format. Try using .getContent() instead, as it selects the whole content.
