Dynamically adding Input form field issue reactjs












6















I am trying to add one cascaded form(inner) field dynamically on click of a button +Add Content. The array for the field is getting updated but the view is still same.



However, when I try to add the outer field on click of a button +Add Heading dynamically its getting added with no issues.
Below is the stackblitz url for reference. Thanks in advance.

          You're only ever rendering one Content field, and the {this.AddContentInput} isn't valid syntax. You can edit the AddContentBox method to render all of the Content fields:



          Original:



          ...
          <FormGroup>
          <Label className="set-label-pos upload-img" for="Heading">Content</Label>
          <input className="form-control" type="text"/>
          </FormGroup>
          {this.AddContentInput}
          ...


          Replaced with:



          ...
          { this.AddContentFields(element) }
          ...


          and



          AddContentFields(element) {
          return element.Content.map(content => {
          return (
          <FormGroup>
          <Label className="set-label-pos upload-img" for="Heading">Content</Label>
          <input className="form-control" type="text"/>
          </FormGroup>
          );
          })
          }

          Your code is working fine and the state is updating perfectly. The problem is that the Content part is added only once in your code. I just used a function which you already added in it



          {this.addContentTextBox(element.Content)}



          Just replace the AddContentBox function with this:






          AddContentBox(){
          return this.state.content.map((element,i)=>(
          <div className="header-content" key={i} >
          <div className="heading-content-wrapper">
          <FormGroup>
          <Label className="set-label-pos upload-img" for="Heading">Heading</Label>
          <input className="form-control" type="text"/>
          </FormGroup>
          {this.addContentTextBox(element.Content)}
          {this.AddContentInput}
          <FormGroup>
          <Button color="success" onClick={this.AddContentInput.bind(this,i)}>+ Add Content</Button>
          </FormGroup>
          </div>
          </div>
          ))
          }





          You have the code in that file, but i think you forgot to add it in the function.



          Hope it helps :)

            You are mixing the content variable. In your function AddContentBox() you are using this.state.content.map(...)



            this.state.content is an array of object like {Heading: '', Content: [{value: ''}]}



            BUT in your function AddContentInput() your are pushing an object inside an object of this array contents[index].Content.push({value:''})



            Depending on your needs you should either push in the root array contents.push({Heading: '', Content: [{value: ''}]} OR iterate the right array in your function AddContentBox() and use this.state.content[0].Content.map(...)

                  </div>
                  ))
                  }





                  You have the code in that file, but i think you forgot to add it in the function.



                  Hope it helps :)

                  Your code is working fine and the state is updating perfectly. The problem is that the Content part is added only once in your code. I just used a function which you already added in it



                  {this.addContentTextBox(element.Content)}



                  Just replace the AddContentBox function with this:






                  AddContentBox(){
                  return this.state.content.map((element,i)=>(
                  <div className="header-content" key={i} >
                  <div className="heading-content-wrapper">
                  <FormGroup>
                  <Label className="set-label-pos upload-img" for="Heading">Heading</Label>
                  <input className="form-control" type="text"/>
                  </FormGroup>
                  {this.addContentTextBox(element.Content)}
                  {this.AddContentInput}
                  <FormGroup>
                  <Button color="success" onClick={this.AddContentInput.bind(this,i)}>+ Add Content</Button>
                  </FormGroup>
                  </div>
                  </div>
                  ))
                  }

                      You are mixing the content variable. In your function AddContentBox() you are using this.state.content.map(...)



                      this.state.content is an array of object like {Heading: '', Content: [{value: ''}]}



                      BUT in your function AddContentInput() your are pushing an object inside an object of this array contents[index].Content.push({value:''})



                      Depending on your needs you should either push in the root array contents.push({Heading: '', Content: [{value: ''}]} OR iterate the right array in your function AddContentBox() and use this.state.content[0].Content.map(...)
