Question

我想使用append添加html代码，但是当第二次添加时，输入中的文本不会跟随新行：

HTML：

    '<form>' +
    '<input type="text" id="newFoldr" name="fname" placeholder=".ex nameFanpage" value="">' +
    '<input type="button" class="cancelButton" id="cancelButton" value="Cancel" data-dismiss="modal" aria-label="Close">' +
    '<input type="button" class="submitButton" id="submitButton" value="Create" style="width:142px;margin-left: 5px;">' +
    '</form>' +

Javascript：

$('.submitButton').click(function () {
    var addFolder = '<div class="_5bm7 _2mk4" role="presentation" style="height: 50px;border:none;"><div class="_5bmf"></div>' +
    '<div class="_1577">' +
    '<div class="ellipsis">' +
    '<div class="_1i5z"><div class="_1i5-">' +
    '</div>' +
    '</div>' +
    '<span id="namaFolder"></span>' +
    '</div>' +
    '</div>' +
    '</div>';

    if( document.getElementById("newFoldr").value === '' ){
        swal("Whoops!", "You need to write something!", "info");
    } else {
        $('.columnFolder').append(addFolder);
        var inputan = document.getElementById("newFoldr").value;
        document.getElementById("namaFolder").innerHTML= inputan;
        swal("Success!", "Your folder has been created!", "success");
    }
});

如果您无法清除输入值，只需在else块中添加以下代码

document.getElementById("newFoldr").value = "";

完整的javascript代码如下

$('.submitButton').click(function () {
    var addFolder = '<div class="_5bm7 _2mk4" role="presentation" style="height: 50px;border:none;"><div class="_5bmf"></div>' +
    '<div class="_1577">' +
    '<div class="ellipsis">' +
    '<div class="_1i5z"><div class="_1i5-">' +
    '</div>' +
    '</div>' +
    '<span></span>' +
    '</div>' +
    '</div>' +
    '</div>';

    if( document.getElementById("newFoldr").value === '' ){
        swal("Whoops!", "You need to write something!", "info");
    } else {
        $('.columnFolder').append(addFolder);
        var inputan = document.getElementById("newFoldr").value;
        $('.columnFolder div._5bm7._2mk4:last').find('span').text(inputan);
        document.getElementById("newFoldr").value = "";
        swal("Success!", "Your folder has been created!", "success");
    }
});

我想要在第二次弹出时不清除输入值
