我想将可编辑div中的字符数限制为10.在用户达到限制后,我想使用.preventDefault()方法来保护div免受其他字符的影响.你能救我吗？JSFiddle https://jsfiddle.net/7x2dfgx6/1/ HTML

<div class="profileInfo" id="About" style="border:solid;" contenteditable="true">OOOOO</div>

JQuery的

    jQuery(document).ready(function($){

    const limit = 10;
    rem = limit - $('#About').text().length;
    $("#counter").append("You have <strong>" + rem + "</strong> chars left.");
    $("#About").on('input', function(event) {
        var char = $('#About').text().length;
        rem = limit - char;
        $("#counter").html("You have <strong>" + rem + "</strong> chars left.");
        if(char>limit)
        {
            event.preventDefault();
            //TODO
        }
    });
});
