在Angular2中使用带有FormGroup的jquery-steps

Question

请参阅以下示例.我已经加载jquery并jquery-steps进入项目,它正在工作.但是,在渲染视图后,更改输入框中的数据不会更新表单组中的值mainForm.我相信原因是jquery-steps动态删除并重构了表单的html,因此表单组不再链接到DOM.

有没有办法mainForm在jquery-steps重构html 后将FormGroup重新绑定到DOM ？

我读到ComponentResolver和ViewContainerRef,是它应该使用那些？你能举个例子说明如何在这种情况下使用它们吗？

谢谢!

<pre>{{ mainForm.value | json }}</pre>

<form [formGroup]="mainForm" id="mainForm" action="#">
    <h1>Account</h1>
    <div>
        <label for="userName">User name *</label>
        <input formControlName="userName" type="text" class="required">
        <label for="password">Password *</label>
        <input formControlName="password" type="text" class="required">
        <label for="confirm">Confirm Password *</label>
        <input formControlName="confirm" type="text" class="required">
        <p>(*) Mandatory</p>
    </div>
    <h1>Finish</h1>
    < div>
        <input formControlName="acceptTerms" type="checkbox" class="required"> 
        <label for="acceptTerms">I agree with the Terms and Conditions.</label>
    </div>
</form>

import {Component, AfterContentInit} from "@angular/core";
import {FormBuilder, Validators, FormGroup} from "@angular/forms";

@Component({
    templateUrl: 'main-view.template.html'
})
export class MainViewComponent implements AfterContentInit {

    private mainForm: FormGroup;

    constructor(private formBuilder: FormBuilder) {
        this.mainForm = this.formBuilder.group({
            userName: ['', Validators.required],
            password: ['', Validators.required],
            confirm: ['', Validators.required],
            acceptTerms: ['', Validators.required],
        });
    }

    ngAfterContentInit() {
        $("#mainForm").steps();
    }
}

这不起作用的主要原因是jquery-steps插件删除了你的html标记.

在angular2中使用jquery是个不错的主意,但是如果你想让它工作,我可以为你提供一点修改库

jquery.steps.js

function render(wizard, options, state) {
+    var contentWrapper = $('<{0} class=\"{1}\"></{0}>'.format(options.contentContainerTag, "content " + options.clearFixCssClass));
+    contentWrapper.append(wizard.children());
    // Create a content wrapper and copy HTML from the intial wizard structure
    var wrapperTemplate = "<{0} class=\"{1}\">{2}</{0}>",
        orientation = getValidEnumValue(stepsOrientation, options.stepsOrientation),
        verticalCssClass = (orientation === stepsOrientation.vertical) ? " vertical" : "",
-       //contentWrapper = $(wrapperTemplate.format(options.contentContainerTag, "content " + options.clearFixCssClass, wizard.html())),
