在我的例子中，在app。module中。ts，我得到这个错误，因为我在imports和entryComponents中声明了组件。

Example:

import { MyComponent } from '....';

@NgModule({
  declarations: [
    MyComponent 
  ],
  imports: [
    MyComponent  -- > remove this from here!!!!
  ],
  providers: [],
  bootstrap: [AppComponent],
  entryComponents: [MyComponent]
})
export class AppModule { }

我在这里还面临着类似的细节问题 上传logo时使用下拉logo上传框

<div>
      <div class="uploader greyLogoBox" id="uploader" flex="64" onclick="$('#filePhoto').click()">
        <img id="imageBox" src="{{ $ctrl.companyLogoUrl }}" alt=""/>
        <input type="file" name="userprofile_picture"  id="filePhoto" ngf-select="$ctrl.createUploadLogoRequest()"/>
        <md-icon ng-if="!$ctrl.isLogoPresent" class="upload-icon" md-font-set="material-icons">cloud_upload</md-icon>
        <div ng-if="!$ctrl.isLogoPresent" class="text">Drag and drop a file here, or click to upload</div>
      </div>
      <script type="text/javascript">
          var imageLoader = document.getElementById('filePhoto');
          imageLoader.addEventListener('change', handleImage, false);

          function handleImage(e) {
              var reader = new FileReader();
              reader.onload = function (event) {

                  $('.uploader img').attr('src',event.target.result);
              }
              reader.readAsDataURL(e.target.files[0]);
          }
      </script>
      </div>

CSS.css

.uploader {
  position:relative;
  overflow:hidden;
  height:100px;
  max-width: 75%;
  margin: auto;
  text-align: center;

  img{
    max-width: 464px;
    max-height: 100px;
    z-index:1;
    border:none;
  }

  .drag-drop-zone {
    background: rgba(0, 0, 0, 0.04);
    border: 1px solid rgba(0, 0, 0, 0.12);
    padding: 32px;
  }
}

.uploader img{
  max-width: 464px;
  max-height: 100px;
  z-index:1;
  border:none;
}



.greyLogoBox {
  width: 100%;
  background: #EBEBEB;
  border: 1px solid #D7D7D7;
  text-align: center;
  height: 100px;
  padding-top: 22px;
  box-sizing: border-box;
}


#filePhoto{
  position:absolute;
  width:464px;
  height:100px;
  left:0;
  top:0;
  z-index:2;
  opacity:0;
  cursor:pointer;
}

在修正之前，我的代码是:

function handleImage(e) {
              var reader = new FileReader();
              reader.onload = function (event) {
                  onclick="$('#filePhoto').click()"
                  $('.uploader img').attr('src',event.target.result);
              }
              reader.readAsDataURL(e.target.files[0]);
          }

控制台的错误:

我解决了它通过删除onclick="$('#文件照片').click()"从div标签。

有时是因为转换数据类型，例如你有一个对象，你认为是字符串。

套接字。以nodejs客户端的Id为例，它不是一个字符串。要将它作为字符串使用，你必须在前面添加单词string:

String(socket.id);

这也会导致最大调用堆栈大小超过错误:

var items = [];
[].push.apply(items, new Array(1000000)); //Bad

我也一样:

items.push(...new Array(1000000)); //Bad

来自Mozilla文档:

But beware: in using apply this way, you run the risk of exceeding the JavaScript engine's argument length limit. The consequences of applying a function with too many arguments (think more than tens of thousands of arguments) vary across engines (JavaScriptCore has hard-coded argument limit of 65536), because the limit (indeed even the nature of any excessively-large-stack behavior) is unspecified. Some engines will throw an exception. More perniciously, others will arbitrarily limit the number of arguments actually passed to the applied function. To illustrate this latter case: if such an engine had a limit of four arguments (actual limits are of course significantly higher), it would be as if the arguments 5, 6, 2, 3 had been passed to apply in the examples above, rather than the full array.

所以尝试:

var items = [];
var newItems = new Array(1000000);
for(var i = 0; i < newItems.length; i++){
  items.push(newItems[i]);
}

在我的例子中，我有两个同名的变量!

发送输入元素而不是它们的值很可能会像FK提到的那样解决它
