在我的例子中，click事件在子元素上传播。所以，我不得不写以下内容:

e.stopPropagation ()

点击事件:

 $(document).on("click", ".remove-discount-button", function (e) {
           e.stopPropagation();
           //some code
        });
 $(document).on("click", ".current-code", function () {
     $('.remove-discount-button').trigger("click");
 });

下面是html代码:

 <div class="current-code">                                      
      <input type="submit" name="removediscountcouponcode" value="
title="Remove" class="remove-discount-button">
   </div>

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。

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，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 { }

在我的例子中，我发送的是输入元素而不是它们的值:

$.post( '',{ registerName: $('#registerName') } )

而不是:

$.post( '',{ registerName: $('#registerName').val() } )

这冻结了我的Chrome标签到一个点，它甚至没有显示我的“等待/杀死”对话框，当页面变得无响应…

我们最近添加了一个字段的管理网站，我们正在工作- contact_type…简单的对吧?好吧，如果你调用select“type”，并试图通过jquery ajax调用发送它，它会失败，这个错误深埋在jquery.js中。

$.ajax({
    dataType: "json",
    type: "POST",
    url: "/some_function.php",
    data: { contact_uid:contact_uid, type:type }
});

问题是，type:type -我相信是我们将参数命名为“type”-有一个名为type的值变量不是问题。我们将其更改为:

$.ajax({
    dataType: "json",
    type: "POST",
    url: "/some_function.php",
    data: { contact_uid:contact_uid, contact_type:type }
});

并相应地重写了some_function.php——问题解决了。
