提交时未输入字段时如何自动滚动到表单区域

Question

我想提交一个表单，但当没有输入字段时，它应该自动指向该区域。我有收音机按钮。当它没有被点击时，它应该自动滚动到单选按钮区域。当我执行代码时，它不是自动滚动到单选按钮，而是自动滚动文本字段。

每当我试图提交表单时，它不是自动滚动的，它只显示错误情况。如何修复此

$('.sellingFormSave').submit(function(e) {
//e.preventDefault();
$('.form_error').remove();
var count = 0;
if (!$('[name=condition]:checked').val()) {
$('.condition_radio .wrapper').after('<label class="form_error" style="color:red">Select the condition of the trucks.</label>');
count++;
}
if ($('[name=product_id]').val() == '') {
var qty = 0;
if (count > 0) {
$('[type=submit]').attr('disabled', false);
return false;
}
}
});

Answer 1

1. 您没有一个名为product_id的字段
2. 如果选中某个单选框，则忽略其他字段。由于无线电是必需的，所以不能触发"；name"；或"；城市；字段，因为浏览器不允许您在不选择收音机的情况下提交
3. 什么是product_name，为什么在不使用product_name的情况下将数量设置为0

这是一个演示。我按下保存按钮，这样你就可以看到浏览器会把注意力集中在空名称上。

下次请让代码与HTML 匹配

$('#sellingFormSave').on("submit", function(e) {
$('.form_error').remove();
if (!$('[name=condition]:checked').val()) {
$('.condition_radio .wrapper').after('<label class="form_error" style="color:red">Select the condition of the trucks.</label>');
}
if ($('[name=name]').val() == '') {
e.preventDefault()
$('[name=name]').focus();
}
});

#dummy { margin-bottom: 1000px }
