Javascript返回false - 来自函数 [英] Javascript return false - from function

问题描述

有什么办法可以做到以下几点：

  validateLogin（）; 
返回false; 
  

但是实际上就像这样..

  validateLogin（）; 
  

以下是函数：

 function validateLogin（）{
 if（hi = true）{
 return true; 
} 
 else {
 return false 
} 
  

我想为表单提交事件附加这个函数，所以如果HI是错误的 - 我想返回false;这意味着它会停止从表单提交..我知道返回假;将这样做，我只需要知道我怎么可以得到这个返回到父功能？

在此先感谢！

  return validateLogin（）;然而，正如mmayo指出的那样，不要忘记返回值：
  

  event.returnValue = false; 
  

Is there any way to do the following:

validateLogin();
return false;

But actually like this..

validateLogin();

And here is the function:

function validateLogin(){
if(hi=true){
return true;
}
else{
return false
}

I want to attach this function for the event of a form being submitted, so if HI is false - i want to return false; meaning it will stop for form from submitting.. i know return false; will do so i just need to know how i can get this return back to the parent function?

Thanks in advance!

解决方案

You can use it as follow:

return validateLogin();

however, as mmayo pointed out, don't forget about the return value:

event.returnValue = false;
