我正在使用直接Web Remoting (DWR) JavaScript库文件,只在Safari(桌面和iPad)中得到一个错误

它说

超过最大调用堆栈大小。

这个错误到底是什么意思,它是否完全停止处理?

Safari浏览器也有任何修复(实际上是在iPad Safari上,它说

JS:执行超时

我认为这是相同的调用堆栈问题)

如果你因为某些原因需要一个无限的进程/递归运行,你可以在一个单独的线程中使用webworker。 http://www.html5rocks.com/en/tutorials/workers/basics/

如果你想操纵dom元素并重新绘制,请使用动画 http://creativejs.com/resources/requestanimationframe/

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]);
}

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。

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>

几乎每个答案都说这只能由无限循环引起。这是不正确的,否则您可以通过深度嵌套调用溢出堆栈(并不是说这是有效的,但它肯定是在可能的范围内)。如果你可以控制你的JavaScript虚拟机,你可以调整堆栈大小。例如:

节点——时= 2000
