前言

本章节记录常用控件 Wizard，NavContainer。

• Wizard控件是一种用于分步导航和指导用户完成多步骤任务的界面控件。它通常用于创建复杂的表单或流程，其中用户需要按照一定的顺序完成多个步骤。Wizard控件可以将整个过程分解为一系列步骤，并允许用户逐步完成每个步骤。
• NavContainer 是 SAPUI5 中用于实现页面导航的容器控件。它允许在同一个页面上管理多个子页面，并支持页面之间的导航。

其路径是：

• sap.m.Wizard
• sap.m.NavContainer

1. Wizard

1.1 基本结构

<Wizard>
<WizardStep></WizardStep>
<WizardStep></WizardStep>
<WizardStep></WizardStep>
</Wizard>

---

1.2 属性

1.2.1 Wizard：complete

• 当所有Step完成时提供Preview按钮绑定事件

	<Wizardid="CreateProductWizard"complete="wizardCompletedHandler">

wizardCompletedHandler:function(){this._oNavContainer.to(this.byId("wizardReviewPage"));},

1.2.2 Wizard：finishButtonText

• 更改最后一个步骤的按钮文本。默认是Preview

1.2.3 Wizard：currentStep

• 指定初始化时显示的步骤

1.2.4 Wizard：backgroundDesign

• 共有4种属性Standard,Solid,List,Transparent。 具体效果差异不大

1.2.5 Wizard：enableBranching

• 可以分配Step中的分支，并指定需要的Step作为下一步
• 要配合WizardStep中的subsequentSteps,nextStep使用.
• 必须初始化时指定subsequentSteps对应组建的nextStep （onAfterRendering）

• View

   <Button text="更换为A-C-B" press="ChangeStep"></Button><Wizard id="customStep" enableBranching="true" backgroundDesign="Solid"><WizardStep id="A" title="A" subsequentSteps="B,C"></WizardStep><WizardStep id="B" title="B" nextStep="D"></WizardStep><WizardStep id="C" title="C" nextStep="D"></WizardStep><WizardStep id="D" title="D" ></WizardStep></Wizard>

• Controller

	onAfterRendering: function () {var stepA = this.byId("A")var stepB = this.byId("B")stepA.setNextStep(stepB)    },ChangeStep:function(){var wizard2 = this.byId("customStep")wizard2.discardProgress(wizard2.getSteps()[0]);var stepA = this.byId("A")var stepC = this.byId("C")stepA.setNextStep(stepC)    },

1.2.6 WizardStep：validated

• 判断当前页面有无错误。如果没有错误则显示下一步按钮，否则不显示下一步按钮
• 再控制器中使用validateStep,invalidateStep控制属性
• 结合activate属性一起使用，activate事件绑定控制validated属性的逻辑

	<WizardStepid="ProductInfoStep"validated="false"title="基本信息"activate="additionalInfoValidation">

	additionalInfoValidation: function () {var name = this.byId("ProductName").getValue();var unit = this.byId("ProductUnit").getValue();if (unit != "EA") {this._wizard.setCurrentStep(this.byId("ProductInfoStep"));this.model.setProperty("/productUnitState", "Error");} else {this.model.setProperty("/productUnitState", "None");}if (name.length < 6) {this._wizard.setCurrentStep(this.byId("ProductInfoStep"));this.model.setProperty("/productNameState", "Error");} else {this.model.setProperty("/productNameState", "None");}if (name.length < 6 || unit != "EA") {this._wizard.invalidateStep(this.byId("ProductInfoStep"));} else {this._wizard.validateStep(this.byId("ProductInfoStep"));}},

1.2.7 WizardStep：complete

• 当点击下一步按钮之后触发事件

• View

	<WizardStepid="PricingStep"complete="inputComplete"validated="true"title="最后确认">

• Controller

	inputComplete: function () {this.model.setProperty("/complete", true)debugger},

1.3 跳转函数

1.3.1 goToStep

• pageno是需要跳转的Step

this._wizard.goToStep(this._wizard.getSteps()[pageno]);

1.3.2 discardProgress

• 撤回所有Step并跳转

this._wizard.discardProgress(this._wizard.getSteps()[pageno]);

2. NavContainer

2.1 基本组成

• 默认会显示第一个Page，之后会通过事件进行Page之间的跳转

<NavContainer><pages><Page></Page><Page></Page></pages>
</NavContainer>

2.2 Page跳转

• 跳转到指定Page

	this._oNavContainer = this.byId("wizardNavContainer");this._oNavContainer.to(this.byId("wizardReviewPage"));

• 跳转到之前Page

	this._oWizardContentPage = this.byId("wizardContentPage");this._oNavContainer.backToPage(this._oWizardContentPage.getId());

• 绑定跳转事件

	var fnAfterNavigate = function () {this._wizard.goToStep(this._wizard.getSteps()[pageno]);this._oNavContainer.detachAfterNavigate(fnAfterNavigate);}.bind(this);this._oNavContainer.attachAfterNavigate(fnAfterNavigate);

3. 示例代码
