javascript - 如何在多个 中显示来自 .map 函数的数据

Question

我已经检查这段代码一段时间了。这是过程:

我正在从服务器检索一些数据。这些数据将使用 .map 函数显示在卡片上。

问题是:它们显示在卡片上，但没有显示在附加的模式上

关注双斜杠注释“//”的代码块

// I started with the map function here 
if(this.state.isLoading === false) {
this.state.data.map((datii,i) => {

  if(isClicked){
    generateButton =    
            <button type="button" className="btn btn-primary" id="postStatus"
                                data-dismiss="modal" data-toggle="modal" data-target={"#exampleModal2"} 
                            onClick={this.handleGeneratedClick} aria-label="Close">
                            Post on social media
                        </button>

    generated = <div className="row">
                  <p className="col-3"><b>Generated Link:</b></p>
                  <p className="col-9">The generated link</p>
                </div>
  }else {        
    generateButton = <button type="button" className="btn btn-primary" onClick={this.handleGeneratedClick}>
                        Generate link
                      </button>
    generated = <div/>
  }

  return(

  content.push(
    <div className="contents" key={datii.campaignId}>

您必须向我们展示您的代码!

但是凭直觉，这就是你如何从 .map 函数中渲染多个 div

    return this.state.serverresponse.map(x=> (
      <div>
          <ExampleComponent
              prop1={x.id}
              prop2={x.data}
              prop3={x.binary}
              prop4={x.label}

          />
        </div>
      ));

this.state.serveresponse 是我存储服务器结果的地方，在我的例子中是一个对象数组。
