如何将javascript创建的节点输入数组

Question

I'm trying to push elements generated from this

function myFunction() 
{ 

    var x=document.getElementById("stat"); 
    var para=document.createElement("p"); 
    var node=document.createTextNode(stat.value); 
    para.appendChild(node);
    var element=document.getElementById("output"); 
    element.appendChild(para); 
    stat.value="" 

} 

into an array to run through 4 separate functions to determine their avg., med., mode, and standard deviation. I thought I'd be about to target them with an getElementByTagName, but it doesnt seem to work.

Answer 1

It's a typo.

You're using stat as a variable name instead of x .

The most important thing for a variable it's the name... you should pick variable names more carefully.

Functions have both a name and a semantic and the semantic (logic) is of course more important than the name (not saying that the name is not important, of course).

But variables are basically just names.

Answer 2

Something like this?

function myFunction(element) 
{ 
  var stat=document.getElementById(element); 
  var para=document.createElement("p"); 
  var node=document.createTextNode(stat.value); 
  para.appendChild(node);
  var element=document.getElementById("output"); 
  element.appendChild(para); 
  stat.value="" 
} 

var elements = ['stat', 'stat2', 'stat3', 'stat4']

for (var i = 0; i < elements.length; ++i) {
  myFunction(elements[i])
}
