Question

我有这样的网页

<div id="home" class="cvitae-section slider sliderStyle7 active"> 
	<div class="cvitae-container"> 
		<div class="slider-content"> 
			<div class="box-container" >  
				<p class="name">  HAMZA KAVAK</p>
				<p class="designation">  &lt; Web Developer /&gt; </p>  
			</div> 
		<img src="img/slider/7-image.png" class="image" alt="Slider"> 
		</div>
	</div>
</div>

我想在webview android上部分查看网页，并从网页中删除一些div元素。

这是来自Java Docs＆gt;＆gt;＆gt; readingURL

String yourHtmlString = Html.toHtml(someString);

现在你有了它的字符串，你可以使用它......

当你完成后，你应该只将你编辑过的字符串转换成html字符串：

import { Component, Input, OnChanges } from '@angular/core';
import { FormGroup, FormBuilder, NgForm, REACTIVE_FORM_DIRECTIVES, Validators } from '@angular/forms';

    @Component({
      selector: '[dependent-row]',
      providers: [],
      template: `
        <tr [formGroup]="dependentForm">
          <td>
            <input type="text" formControlName="foo">
          </td>
          <td>
            <input type="text" formControlName="bar">
          </td>
        </tr>
      `,
      directives: [REACTIVE_FORM_DIRECTIVES]
    })
    export class DependentRowComponent implements OnChanges {
      @Input() dependent: any;
      _Form: any;

      constructor(fb: FormBuilder) {
        this.dependentForm = fb.group({
          foo: [''],
          bar: [''],
        })
      }

      ngOnChanges() {
        this._Form.find('foo').updateValue(this.dependent.foo);
        this._Form.find('bar').updateValue(this.dependent.bar);
      }
    }

!!! ...但请注意并非所有html标签都在Android上工作 !!!
