逐步模式引导

Question

我试图逐步验证每个步骤，但是我只能验证输入错误，但不能验证选择。 希望当select的值等于0（0）时，也会进行验证。

有人可以帮我这个JS吗？ 我将非常感谢。

  $(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[type='text']"), isValid = true; $(".form-group").removeClass("has-error"); for(var i=0; i<curInputs.length; i++){ if (!curInputs[i].validity.valid){ isValid = false; $(curInputs[i]).closest(".form-group").addClass("has-error"); } } if (isValid) nextStepWizard.removeAttr('disabled').trigger('click'); }); $('div.setup-panel div a.btn-primary').trigger('click'); });

您需要在allNextBtn.click事件内的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');
});
