使用WS添加WTFORM字段

Question

我目前正在尝试使用WTFORM重写表单

当我尝试替换JS输入创建时，我陷入了困境。我有以下jQuery派，我想用一个WS调用来替换它，以在WTFORM类中插入一个新字段。

$(
    '<div class="MAIN_order_' + (cptOrder + 1) + '" style="display: none">' +
    '        <div class="form-group">' +
    '            <label for="orderNumber_' + (cptOrder + 1) + '">' + gt.gettext('ORDER_NUMBER') + ' ' + (cptOrder + 1) + ' <a href="#removeorder" class="ORDER_' + (cptOrder + 1) + '" onclick="removeOrderNumber(this)"><i class="fa fa-minus-square" aria-hidden="true"></i></a> </label>' +
    '            <div class="input-group mb-2">' +
    '                <div onclick="drawRectangle(document.getElementById(\'orderNumber_' + (cptOrder + 1) + '\'))" class="input-group-prepend" style="display:none;">' +
    '                    <div class="input-group-text"><i class="fas fa-eye" aria-hidden="true"></i></div>' +
    '                </div>' +
    '                <input autocomplete="off" required name="facturationInfo_order_number_' + (cptOrder + 1) + '" id="orderNumber_' + (cptOrder + 1) + '" type="text" class="form-control" onfocusout="ocrOnFly(true, this, true); removeRectangle()" onfocusin="ocrOnFly(false, this, true)">\n' +
    '            </div>' +
    '        </div>' +
    '    </div>'
).insertAfter(lastOrder).slideToggle();

这可能吗？如果是，我该怎么办？
