我找到了一个代码片段,它完全是我需要的,只需稍加改动.
The sample code is here,我试图创建一个可以访问
here的示例表单.
我需要的唯一调整是,我想在加载表单后显示必填字段的星号.但截至目前,它显示了错误样式(页面打开时不需要).我该如何更改表格？
脚本
$(document).ready(function() {
$('.input-group input[required], .input-group textarea[required], .input-group select[required]').on('keyup change', function() {
var $form = $(this).closest('form'),
$group = $(this).closest('.input-group'),
$addon = $group.find('.input-group-addon'),
$icon = $addon.find('span'),
state = false;
if (!$group.data('validate')) {
state = $(this).val() ? true : false;
} else if ($group.data('validate') == "email") {
state = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/.test($(this).val())
} else if ($group.data('validate') == 'phone') {
state = /^[(]{0,1}[0-9]{3}[)]{0,1}[-\s\.]{0,1}[0-9]{3}[-\s\.]{0,1}[0-9]{4}$/.test($(this).val())
} else if ($group.data('validate') == "length") {
state = $(this).val().length >= $group.data('length') ? true : false;
} else if ($group.data('validate') == "number") {
state = !isNaN(parseFloat($(this).val())) && isFinite($(this).val());
}
if (state) {
$addon.removeClass('danger');
$addon.addClass('success');
$icon.attr('class', 'glyphicon glyphicon-ok');
} else {
$addon.removeClass('success');
$addon.addClass('danger');
$icon.attr('class', 'glyphicon glyphicon-remove');
}
if ($form.find('.input-group-addon.danger').length == 0) {
$form.find('[type="submit"]').prop('disabled', false);
} else {
$form.find('[type="submit"]').prop('disabled', true);
}
});
$('.input-group input[required], .input-group textarea[required], .input-group select[required]').trigger('change');
});

最佳答案 您需要在脚本中注释以下行.
$('.input-group input[required], .input-group textarea[required], .input-group select[required]').trigger('change');
这是您的文档中的最后一行.这是负责在页面加载时触发更改事件并将星号更改为交叉的行.只需评论这一行就可以了.
编辑
添加dangerclass而不是info类;默认情况下,这将以红色显示您的星号,在验证时,它将获得带有复选标记的绿色背景.即,修改星号表格组如下.
可选的
注意
撤消我之前建议的脚本更改.
