Question

如何让一个JS函数的参数是带有参数的函数名来调用另一个函数？

类似的东西：

onClick="Clicked(this, 'SomeFunction('test')'"

此致

Answer 1

onClick = "Clicked(this, function () {SomeFunction('test')});"


function Clicked (obj, functionToFire)
{
   functionToFire();
}

Answer 2

<span onclick="Clicked(this, 'SomeFunc', ['test', 123])">AAAA</span>

...

function Clicked(thisObject, funcName, params)
{
 // find an object with name funcName in default (window) scope
 var func = window[funcName];

 // test that the object exist and that it's a function
 if (func && typeof func == "function")
 {
  // call the function with passed params
  // passing 'thisObject' enables to use 'this' keyword within the called function
  func.apply(thisObject, params);

  // as an alternative you may call it without 'this' object
  func.apply(null, params);
 }
}

function SomeFunc(text, num)
{
    alert("text: " + text + ", number: " + num);
}

Answer 3

<script>
function doSomeWork(arg1, arg2)
{
    arg2();
}
function displayThis(msg)
{
    alert(msg);
}
doSomeWork("11",function(){ displayThis("123");});
</script>

Answer 4

你有什么工作，但是，你需要使用javascript eval函数来评估函数中的值一次：

function Clicked(obj, functionText)
{
   // do something with object....
   eval(functionText);
}

否则，如果没有参数，您可以随时传递函数：

onClick="Clicked(this, SomeFunction)"

并实现如下：

function Clicked(obj, func)
{
    // do something with object...
    func();
}

Answer 5

这不可能更简单：

onClick = "function() { someFunction('test') }"

如何将JavaScript函数调用作为参数包含在另一个JavaScript函数中？
