I am using textarea to enter text and every time i send text, i have to press Shift Enter
but when the text is sent it adds /n at the end, I'm using the Enter newline key instead of submit

Ex: hello => hello\n

Image not selected send by key enter: here is my code:

    checkSubmitKey() {
      if (!this.isEnterSubmit) {
        this.sendMessage();
      }
    },
    
    
    onChangeInput() {
      this.getTextareaRef().addEventListener("keyup", (e) => {
        this.handlesaveDraftMessages()
        if (e.key === "Enter" && !e.shiftKey && this.isEnterSubmit) {
          this.sendMessage();
          this.resizeTextarea();
        }
      });
      this.resizeTextarea();
    },
    
    
    resizeTextarea() {
      const el = this.getTextareaRef();

      if (!el) {
        return;
      }

      el.style.height = "auto";
      let newHeight = el.scrollHeight;
      el.style.height = `${newHeight}px`;
    },

<textarea
     rows="1"
     id="roomTextarea"
     ref="roomTextarea"
     v-model="messageInput"
     :placeholder="$t('containers.admin.chat.chatPlaceholder')"
     
     @keyup="onChangeInput"
     @keyup.enter.shift.exact.prevent="checkSubmitKey"
     @click.self="checkmarkSeen"
     @paste="onPasteClipboard"
 />

how do i fix the above
thanks for your help !

CodePudding user response：

Instead of keyup, use keydown event and then preventDefault() while Enter is hit without shift key:

document.querySelector('textarea').addEventListener('keydown', e => {
  if(e.key === 'Enter' && !e.shiftKey) {
    e.preventDefault();
    console.log('send:', e.target.value);
  }
});

<textarea></textarea>
