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)


当前回答

我在express/nodejs应用程序中得到了这个错误,当MongoDB数据库的模式和我们创建的模型不匹配时。

其他回答

对于我这个TypeScript初学者来说,这是_var1的getter和setter的问题。

class Point2{
    
    constructor(private _var1?: number, private y?: number){}

    set var1(num: number){
        this._var1 = num  // problem was here, it was this.var1 = num
    }
    get var1(){
        return this._var1 // this was return this.var1
    }
}

在Angular中,如果你使用mat-select并且有400多个选项,可能会出现这个错误 https://github.com/angular/components/issues/12504

你必须更新@angular/material版本

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]);
}

我在express/nodejs应用程序中得到了这个错误,当MongoDB数据库的模式和我们创建的模型不匹配时。

你可以在crome浏览器中找到你的递归函数,按ctrl+shift+j,然后source选项卡,它会给你代码编译流程,你可以在代码中使用断点。
