我试图逐步验证每个步骤，但我只能验证输入错误，但不能验证选择。 希望当select的值等于零（0）时，也会进行验证。
有人可以帮我这个JS吗？我将非常感谢。

答案 0 :(得分：0)
您需要在 allNextBtn.click 事件中的for循环中检查控件类型，如下所示：
for(var i=0; i<curInputs.length; i++){
//if the control is select check the selected index if it is ZERO
if ( $(curInputs[i]).is('select') && (curInputs[i].selectedIndex === 0)
{
isValid = false;
}
//else check control validity
else if (!curInputs[i].validity.valid)
{
isValid = false;
}
if(!isValid)
{
$(curInputs[i]).closest(".form-group").addClass("has-error");
}
}
并更改此行：
curInputs = curStep.find("input[type='text'],input[type='url'],select[type='text']"),
对此：
curInputs = curStep.find("input[type='text'],input[type='url'],select"),
这是完整的js代码：
$(document).ready(function () {
var navListItems = $('div.setup-panel div a'),
allWells = $('.setup-content'),
allNextBtn = $('.nextBtn');
allWells.hide();
navListItems.click(function (e) {
e.preventDefault();
var $target = $($(this).attr('href')),
$item = $(this);
if (!$item.hasClass('disabled')) {
navListItems.removeClass('btn-primary').addClass('btn-default');
$item.addClass('btn-primary');
allWells.hide();
$target.show();
$target.find('input:eq(0)').focus();
$target.find('select:eq(0)').focus();
}
});
allNextBtn.click(function(){
var curStep = $(this).closest(".setup-content"),
curStepBtn = curStep.attr("id"),
nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next().children("a"),
curInputs = curStep.find("input[type='text'],input[type='url'],select"),
isValid = true;
$(".form-group").removeClass("has-error");
//BEGIN EDIT
for(var i=0; i<curInputs.length; i++){
//if the control is select check the selected index if it is ZERO
if ( $(curInputs[i]).is('select') && (curInputs[i].selectedIndex === 0))
{
isValid = false;
}
//else check control validity
else if (!curInputs[i].validity.valid)
{
isValid = false;
}
if(!isValid)
{
$(curInputs[i]).closest(".form-group").addClass("has-error");
}
}
//END EDIT
if (isValid)
nextStepWizard.removeAttr('disabled').trigger('click');
});
$('div.setup-panel div a.btn-primary').trigger('click');
});
