Enter键验证contenteditable

Question

我有一个标题，用户可以修改，因为contenteditable。我希望当用户按下Enter时，这会验证标题而不是传递一行。

<div class="panel-participants-title"
     *ngIf="thread.title !== '' ">
    <div class="panel-title"
         contenteditable="true">
           {{thread.title.substring(1)}}
    </div>
</div>


.panel-participants-title:hover > *[contenteditable="true"] {
  background: #989898;
}
.panel-participants-title > *[contenteditable="true"] {
  outline: 0;
}

///// UPDATE

<div class="panel-participants-title">
     <div class="panel-title"
          contenteditable="true"
          (keypress)= "validateTitle($event)">
              {{thread.title.substring(1)}}
     </div>
</div>

validateTitle(event: any): void {
  if(event.keyCode===13) {
    document.getElementById("panel-title").submit();
  }
}

//////// UPDATE2

validateTitle(event: any): void {
  if(event.keyCode===13) {
    event.preventDefault();
    event.stopPropagation();
    event.submit();
  }
}

Answer 1

这是一个小提琴的工作示例，如果它关闭:)

document.querySelector('#id1').addEventListener('keypress', function (e) {
    var key = e.which || e.keyCode;
    if (key === 13) { // 13 is enter
      	var text = document.getElementById("id1").value;
        if (text.includes("w")) {
        	alert("Omg, the string contains a W, try again");
        } else {
     		document.getElementById("id1").blur();
        }
    }
});

Input Field <input id="id1" type="text" name="fname">

Answer 2

onKeyPress="if(event.keyCode == 13) validerForm();"

和

function validerForm(){
    document.getElementById("formulaire").submit();
}

通常这就是你想要做的。基本上当键号13（Enter键）并按下它时会启动一个将验证表格的功能。
