未捕获的TypeError: form.steps不是函数
提问于 2016-06-13 17:49:45
我正在尝试为我的窗体创建一个简单的向导。但是它会给我一个"CursusWizard.js:3未捕获函数: form.steps不是一个函数“错误。
我也是第一次使用Angular，我想这可能和我的javascript不能正常工作有关。
这是我的html和表单：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title> Cursus </title>
</head>
<form id="example-advanced-form" class="form-horizontal" name="form" action="#" ng-submit="addCursus()">
<h3>Cursus aanmaken</h3>
<fieldset>
<legend> Cursus informatie</legend>
<label for ="naam"> Cursus naam</label>
<input id="naam" name="naam" type="text" class="required" ng-model="formCursus.name">
<label for ="cursuscode"> Cursus code</label>
<input id="cursuscode" name="cursuscode" type="text" class="required" ng-model="formCursus.cursuscode">
<label for ="aantalec">Aantal ec </label>
<input name="aantalec" type="text" list="aantalec" class="required" ng-model="formCursus.aantalec">
<datalist id="aantalec">
<option value="Boston">
<option value="Cambridge">
</datalist>
<label for ="periode">Periode </label>
<input name="periode" type="text" list="periode" class="required" ng-model="formCursus.periode">
<datalist id="periode">
<option value="Boston">
<option value="Cambridge">
</datalist>
<button class="btn-default" type="submit">Add</button>
<p>(*) Mandatory</p>
</fieldset>
<h3>Profile</h3>
<fieldset>
<legend>Profile Information</legend>
<label for="name-2">First name *</label>
<input id="name-2" name="name" type="text" class="required">
<label for="surname-2">Last name *</label>
<input id="surname-2" name="surname" type="text" class="required">
<label for="email-2">Email *</label>
<input id="email-2" name="email" type="text" class="required email">
<label for="address-2">Address</label>
<input id="address-2" name="address" type="text">
<label for="age-2">Age (The warning step will show up if age is less than 18) *</label>
<input id="age-2" name="age" type="text" class="required number">
<p>(*) Mandatory</p>
</fieldset>
<h3>Warning</h3>
<fieldset>
<legend>You are to young</legend>
<p>Please go away ;-)</p>
</fieldset>
<h3>Finish</h3>
<fieldset>
<legend>Terms and Conditions</legend>
<input id="acceptTerms-2" name="acceptTerms" type="checkbox" class="required"> <label for="acceptTerms-2">I agree with the Terms and Conditions.</label>
</fieldset>
</form>
</html>以下是我使用javascript编写的代码：
var form = $("#example-advanced-form").show();
form.steps({
headerTag: "h3",
bodyTag: "fieldset",
transitionEffect: "slideLeft",
onStepChanging: function (event, currentIndex, newIndex)
{
// Allways allow previous action even if the current form is not valid!
if (currentIndex > newIndex)
{
return true;
}
// Forbid next action on "Warning" step if the user is to young
if (newIndex === 3 && Number($("#age-2").val()) < 18)
{
return false;
}
// Needed in some cases if the user went back (clean up)
if (currentIndex < newIndex)
{
// To remove error styles
form.find(".body:eq(" + newIndex + ") label.error").remove();
form.find(".body:eq(" + newIndex + ") .error").removeClass("error");
}
form.validate().settings.ignore = ":disabled,:hidden";
return form.valid();
},
onStepChanged: function (event, currentIndex, priorIndex)
{
// Used to skip the "Warning" step if the user is old enough.
if (currentIndex === 2 && Number($("#age-2").val()) >= 18)
{
form.steps("next");
}
// Used to skip the "Warning" step if the user is old enough and wants to the previous step.
if (currentIndex === 2 && priorIndex === 3)
{
form.steps("previous");
}
},
onFinishing: function (event, currentIndex)
{
form.validate().settings.ignore = ":disabled";
return form.valid();
},
onFinished: function (event, currentIndex)
{
alert("Submitted!");
}
}).validate({
errorPlacement: function errorPlacement(error, element) { element.before(error); },
rules: {
confirm: {
equalTo: "#password-2"
}
}
});我做错了什么？

var form = $("#example-advanced-form").show();您将.show()返回的值赋给变量form，据我所知，在jquery中.show()不返回任何值，因此表单可能没有方法方法step()，引用form.step()将导致错误。

您是否包含了jquery cdn for steps函数？请参考下面的cdn链接，尝试添加cdn并在添加后发布您的发现。"https://cdnjs.cloudflare.com/ajax/libs/jquery-steps/1.1.0/jquery.steps.min.js“
祝你编码愉快！
