Question

你好动态函数不起作用问题在哪里？

DynamicCreateFunction函数有效，但runtimeFunction无效。

  function DynamicCreateFunction(func) {

    var runtimeFunction = new Function(func);
    runtimeFunction ();
}

     function ExpensesGrid()
    {
         alert('working');
    }

Answer 1

您正在尝试传递function作为参数，您可以这样做：

function DynamicCreateFunction(callback){
   callback.call(this); //or .apply() or simply callback()
}

如果您想执行ExpensesGrid，请执行

DynamicCreateFunction(ExpensesGrid);

Answer 2

 hello thanks for the reply but I see the `"call" is not supported error` why ?

    function DynamicCreateFunction(callback){
   callback.call(this); //or .apply() or simply callback()
}

但问题解决了，替代解决了，“功能正在发挥作用”

dynamicFunction = window[func]; 
dynamicFunction();

谢谢 -
