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;

#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。

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]);
}

这个问题可能是因为递归调用没有任何终止的基本条件。

就像在我的情况下，如果你看到下面的代码，我有相同的API调用方法和方法，我用来执行操作后的API调用。

const getData = async () => {
try {
  const response = await getData(props.convID);
  console.log("response", response);
 } catch (err) {
  console.log("****Error****", err);
}
};

基本上，解决方案就是删除这个递归调用。

如果您不小心导入/嵌入了相同的JavaScript文件两次，有时会出现这种情况，值得在检查器的资源选项卡中检查。

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。

dtTable.dataTable({
    sDom: "<'row'<'col-sm-6'l><'col-sm-6'f>r>t<'row'<'col-sm-6'i><'col-sm-6'p>>",
    "processing": true,
    "serverSide": true,
    "order": [[6, "desc"]],
    "columnDefs": [
        {className: "text-right", "targets": [2, 3, 4, 5]}

    "ajax": {
        "url": "/dt",
        "data": function (d) {
            d.loanRef = loanRef;
        }
    },
    "fnRowCallback": function (nRow, aData, iDisplayIndex, iDisplayIndexFull) {
        var editButton = '';
        // The number of columns to display in the datatable
        var cols = 8;
        // Th row element's ID
        var id = aData[(cols - 1)];
    }
});

在上面的数据函数中，我使用了相同的名称d.loanRef = loanRef，但没有创建变量loanRef，因此递归地声明了自己。

解决方案:声明一个loanRef变量，或者更好的是，使用与d.loanRef不同的名称。
